Description

Un sistema para la programaciĆ³n de televisiĆ³n.
Antecedentes de la invenciĆ³n 1. Campo de la invenciĆ³n
La presente invenciĆ³n se refiere, en general, a un sistema y un proceso, que permiten a un telespectador acceder a listados de programas de televisiĆ³n, y usar los listados de programas de un modo sencillo y adecuado, para controlar el funcionamiento de un grabador de cintas de vĆ­deo (VCR (video cassette recorder)), u otro dispositivo de grabaciĆ³n. Adicionalmente, se refiere a un sistema y un proceso, tales que crean un directorio de programas grabados por tĆ­tulo, para una fĆ”cil recuperaciĆ³n y reproducciĆ³n del programa. MĆ”s en particular, se refiere a un dispositivo y proceso en los que el VCR, u otro dispositivo de grabaciĆ³n, estĆ” controlado por una simple selecciĆ³n del tĆ­tulo del programa y un comando de grabaciĆ³n, incluso para grabar a unas fecha y hora futuras. MĆ”s especĆ­ficamente, se refiere a un sistema, y proceso, que incorpora un interfaz de usuario intuitivo.
2. DescripciĆ³n del arte previo
La dificultad de configurar un VCR para grabaciĆ³n automĆ”tica en una fecha futura, es notoria. Incluso usuarios sofisticados, tĆ©cnicamente hablando, con frecuencia cometerĆ”n equivocaciones en el procedimiento de programaciĆ³n del VCR, que les hacen grabar el programa equivocado, o no grabar nada en absoluto. Esta dificultad, incluso ha tenido por resultado una sustancial cantidad de humor, dedicada al objeto de programar VCRs.
La dificultad de programar VCR ha sido aliviada, de algĆŗn modo, mediante el desarrollo de los VCRs que usan un receptor de televisiĆ³n como pantalla para mensajes de usuario, e informaciĆ³n de vuelta al usuario, durante el proceso de programaciĆ³n. La Patente U.S. 4.908.713, publicada el 13 de marzo de 1990, de Michael R. Levine, revela un VCR que emplea el receptor de televisiĆ³n como una pantalla para programaciĆ³n VCR, con un interfaz interactivo de usuario para dirigir al usuario en base a un esquema paso a paso. Semejante interfaz de usuario, elimina una gran cantidad de misterio de la programaciĆ³n VCR, pero los usuarios siguen teniendo dificultad con un semejante interfaz basado en Ć³rdenes, y encuentran problemas para llevar a cabo la programaciĆ³n, sin cometer errores que les hagan fallar en la grabaciĆ³n de programas que les gustarĆ­a ver en un momento diferente que aquel en el que han sido emitidos
La Patente U.S. 4.706.121, publicada el 10 de noviembre de 1987, asignada comĆŗnmente a Patrick Young, revela un sistema y proceso en el usuario las selecciones del usuario, a partir de la informaciĆ³n de programaciĆ³n de televisiĆ³n, son empleadas para el control automĆ”tico de un VCR. Esa patente solo contiene una descripciĆ³n de un interfaz de usuario, propuesto para un proceso y un sistema semejantes. Sin embargo, la provisiĆ³n de un interfaz de usuario altamente intuitivo, que haga, a tales sistema y proceso, fĆ”ciles y adecuados para trabajar, es una tarea difĆ­cil. El desarrollo adicional de este sistema, y proceso, ha producido un cambio considerable en el interfaz de usuario respecto del propuesto originalmente.
Adicionalmente, para simplificar la programaciĆ³n VCR, los usuarios que hacen una cantidad sustancial de grabaciones de cintas, tambiĆ©n necesitan un sistema mejorado y proceso para seguir el rastro de sus programas grabados. La AplicaciĆ³n de No. de Serie 07/219.971, presentada el 15 de julio de 1988 en nombre de Patrick Young, revela un sistema y un proceso que proporcionan capacidad de indexaciĆ³n para material grabado. Un interfaz de usuario para un sistema, y proceso, de programaciĆ³n de televisiĆ³n, deberĆ­a tambiĆ©n manejar esta capacidad de un modo intuitivo.
La publicaciĆ³n WO 98/03085 revela un selector de programa automĆ”tico para aparatos a distancia, que emplea una pantalla de visual para mostrar un variedad de palabras e imĆ”genes. Puede ser activada una pantalla por puntos, que se despliega sobre la pantalla visual.
AsĆ­, mientras que el arte relativo al control de VCRs y a sistemas de programaciĆ³n de televisiĆ³n es un arte bien desarrollado, permanece una necesidad para un sistema, y proceso, de programaciĆ³n de televisiĆ³n, que incorpore un interfaz de usuario mejorado. En particular, a diferencia de la mayorĆ­a de los menĆŗs de ordenador, una guĆ­a de TV en cuadrĆ­cula es un arreglo de celdas irregulares, donde el tamaƱo de celda puede variar desde una fracciĆ³n de una hora, hasta una celda que se extiende por muchas horas, mĆ”s allĆ” de la pantalla actual. Si este arreglo se navega con un cursor que va de celda a celda, un simple comando de cursor puede producir violentos cambios de pantalla. Por ejemplo, una orden de cursor a la derecha puede producir un salto abrupto, a una celda situada a varias horas desde la pĆ”gina actual. Esto no solo resulta perturbador, sino que puede llevar considerables esfuerzos recuperar la situaciĆ³n anterior. Claramente, se necesita un movimiento de cursor mĆ”s suave, para las celdas irregulares que se encuentran en una guĆ­a de TV en cuadrĆ­cula.
Las guĆ­as de programaciĆ³n de televisiĆ³n en cuadrĆ­cula impresas, a menudo incluyen informaciĆ³n adicional junto al tĆ­tulo del programa y nombres de emisiĆ³n. Tales cuadrĆ­culas se proporcionan tambiĆ©n, tĆ­picamente, en combinaciĆ³n con una programaciĆ³n impresa mĆ”s detallada que contiene una sinopsis de cada programa, si el programa es una repeticiĆ³n, clasificaciones para las pelĆ­culas, y otra informaciĆ³n. Cuando se usa un receptor de televisiĆ³n, como pantalla para un sistema de programaciĆ³n, el tamaƱo y resoluciĆ³n de la televisiĆ³n limita la cantidad de texto que puede ser mostrado con la cuadrĆ­cula. Se necesita tĆ©cnicas mejoradas para llevar la mĆ”xima informaciĆ³n al usuario, de una forma que se entienda fĆ”cilmente, dentro de las limitaciones de la pantalla de la televisiĆ³n. Cuando estĆ” disponible un gran nĆŗmero de canales para ser vistos, existe tambiĆ©n la necesidad de ordenar la presentaciĆ³n de informaciĆ³n de forma mĆ”s conveniente para el usuario.
Sumario de la invenciĆ³n
Correspondientemente, es un objetivo de la invenciĆ³n proporcionar un sistema de programaciĆ³n de televisiĆ³n, y proceso, con un interfaz de usuario que estĆ© configurado para compensar la naturaleza particular de la informaciĆ³n de programaciĆ³n de televisiĆ³n.
Es un objetivo mĆ”s de la invenciĆ³n, proporcionar un interfaz de usuario que tenga un funcionamiento de cursor que compense un formato de cuadrĆ­cula, de la informaciĆ³n de programaciĆ³n de televisiĆ³n, irregular.
Es otro objetivo de la invenciĆ³n proporcionar un semejante interfaz de usuario, en el que la informaciĆ³n de programaciĆ³n estĆ© presentada en un formato que compense la resoluciĆ³n limitada de la pantalla de televisiĆ³n.
Es aĆŗn otro objetivo mĆ”s de la invenciĆ³n, proporcionar un semejante interfaz de usuario en el que informaciĆ³n de programaciĆ³n suplementaria, sea presentada en superposiciones que obscurezcan una mĆ­nima cantidad de otra informaciĆ³n Ćŗtil.
Es aĆŗn otro objetivo mĆ”s de la invenciĆ³n, proporcionar un semejante interfaz de usuario en el que el orden de presentaciĆ³n de la informaciĆ³n de programaciĆ³n, pueda ser personalizado segĆŗn las preferencias del usuario.
La consecuciĆ³n de estos objetivos, y otros relacionados, puede ser lograda mediante el uso del nuevo sistema, y proceso, de programaciĆ³n de televisiĆ³n, aquĆ­ revelado. Un sistema de programaciĆ³n de televisiĆ³n que incluye un interfaz de usuario de acuerdo con esta invenciĆ³n, tiene una visualizaciĆ³n. Se conecta un medio a la pantalla, para mostrar la programaciĆ³n de televisiĆ³n en la pantalla como un conjunto de celdas irregulares, que varĆ­an en sus dimensiones longitudinales, en correspondencia a las diferentes duraciones del tiempo del programa de televisiĆ³n. Se conecta un medio a la pantalla, para proporcionar un cursor con la programaciĆ³n de televisiĆ³n en la pantalla. El cursor tiene una longitud variable, que corresponde a la longitud de una de las celdas irregulares, seleccionada, en la que el cursor estĆ” localizado. Se conecta un medio, al medio para proporcionar el cursor, para mover el cursor en el conjunto, mediante una serie de pasos de igual longitud. Al menos una, de las celdas irregulares, tiene una longitud que es mayor que la longitud de los pasos.
La invenciĆ³n se expone en las reivindicaciones 1, 10 y 18.
Se expone algunas caracterĆ­sticas preferidas de la invenciĆ³n en las reivindicaciones dependientes.
La consecuciĆ³n de los objetivos, ventajas y caracterĆ­sticas de la invenciĆ³n, mencionados, y otros relacionados, deberĆ­an ser mĆ”s fĆ”cilmente evidentes para aquellos cualificados en el arte, despuĆ©s de examinar la siguiente descripciĆ³n mĆ”s detallada de la invenciĆ³n, tomada junto con los dibujos, en los cuales:

DescripciĆ³n detallada de la invenciĆ³n
Volviendo ahora a los dibujos, mĆ”s en particular a las figuras 1-7, se muestra una serie de pantallas de menĆŗ 10, 12, 14, 16, 18, 20 y 22 empleadas en el funcionamiento del sistema, y el desempeƱo del proceso, de la invenciĆ³n. Las pantallas 10, 12, 14, 18 y 20, constan cada una de un conjunto 24 de celdas irregulares 26 que varĆ­an en longitud, que corresponden a distintas duraciones de programas de televisiĆ³n, de media hora, a una hora y media, o mĆ”s. El conjunto estĆ” dispuesto como tres columnas 28 de media hora de duraciĆ³n, y doce filas 30 de listados de programas. Algunos de los listados de programa solapan dos, o mĆ”s, de las columnas 28, debido a su longitud. Debido a la extensa variabilidad de la longitud de las celdas 26, si un cursor convencional empleado para seleccionar una localizaciĆ³n del celda, fuera a dar simplemente un paso desde una celda a otra, el resultado podrĆ­a ser cambios bruscos en las pantallas 10, 12, 14, 18 y 20, cuando se moviera el cursor desde una celda 26 de longitud de varias horas, a una celda adyacente en la misma fila. Tales cambios bruscos desorientan a un usuario del sistema.
Una forma eficaz de dominar el movimiento, es asumir que detrĆ”s de todo conjunto 24 hay un conjunto subyacente de celdas regulares. Restringiendo los movimientos del cursor a las celdas regulares, se evitarĆ” cambios bruscos en la pantalla. Sin embargo, ahora hay una ambigĆ¼edad potencial, entre la celda subyacente que gobierna el movimiento del cursor, y una celda visible 26 que soporta el tĆ­tulo del programa.
Es decir: si el cursor se mueve en pasos de media hora, y la longitud de celda es, digamos cuatro horas, ĀædeberĆ­a el cursor ser 1/2 hora de largo, o cuatro horas de largo? Si el cursor solo se extiende por el intervalo de la celda subyacente (1/2 hora), el cursor aparece destacando un segmento de la celda, lo cual es engaƱoso. Por otra parte, si el curso se extiende a las cuatro horas enteras del listado de TV, la posiciĆ³n subyacente del cursor estarĆ” oculta. En este caso, ordenes a izquierda/derecha del cursor, aparecerĆ”n como inoperantes mientras atraviesa una celda larga. La ausencia de retroalimentaciĆ³n, seguida de una orden de cursor, estĆ” confundiendo a los usuarios. Por lo tanto, para el conjunto irregular 24 se requiere un cursor innovador 32 (figura 1), que satisfaga varios requerimientos contradictorios.
Con el cursor 32, toda la celda 26 estĆ” destacada en 3-D, empleando una sombra desplazada convencional 34. La sombra desplazada 34 es una barra negra que subraya toda la celda, y rodea el borde derecho de la celda. Para etiquetar la posiciĆ³n subyacente - que define donde estĆ” el cursor 32 y, asĆ­, donde harĆ” el siguiente movimiento - partes 36 de la barra negra, fuera de la actual posiciĆ³n subyacente, estĆ”n segmentadas, mientras que la posiciĆ³n actual estĆ” pintada de forma continua.
A lo largo de una celda de media hora 26, la barra de subrayado de la sombra desplazada serĆ” siempre negro continuo. Las figuras 2 y 3 muestran el cursor 32, tal como aparece para un programa de media hora. Para programas que van mĆ”s allĆ” de 1/2 hora, solo la posiciĆ³n actual de 1/2 hora serĆ” negro continuo. Todas las posiciones restantes estarĆ”n a franjas. Si el cursor es movido a la izquierda o la derecha, la secciĆ³n continua se moverĆ” correspondientemente, proporcionando retroalimentaciĆ³n visual completa. AsĆ­, este cursor 32 de sombra desplazada en 3D modificado, satisface las demandas presentadas mĆ”s arriba: se expande a toda la celda, pero aĆŗn asĆ­ destaca claramente la posiciĆ³n subyacente actual. El movimiento del cursor 32 siempre serĆ” visible, incluso para celdas 26 que son mucho mĆ”s largas que la celda subyacente.
Un icono de continuidad de la cuadrĆ­cula 38 se muestra en la figura 1. Las guĆ­as de programaciĆ³n de televisiĆ³n impresas, a menudo incluyen comentarios entre parĆ©ntesis (tal como "cont.") para indicar la continuidad del programa. En una guĆ­a electrĆ³nica mostrada en una pantalla de TV, el espacio limitado para texto, excluye comentarios entre parĆ©ntesis. Para conservar espacio, se emplearĆ” un icono 38 para indicar la continuidad de celda 26. En el borde de una celda 26 que continĆŗa en la siguiente pantalla, se superpondrĆ” un icono de flecha 38 que apunta a la derecha. El sentido de la flecha siempre apunta a la derecha, que es la direcciĆ³n en que transcurren los programas.
Las figuras 2 y 3 muestran representaciones del estado de grabaciĆ³n. Cuando un programa ha sido seleccionado para su grabaciĆ³n, su celda del listado 26 estarĆ” subrayada, o destacada, en rojo como se indica en 40. Si se ha aƱadido o borrado tiempo de seguridad, la celda se extenderĆ” o contraerĆ” para reflejar el cambio. La continuidad de la celda 26 se tratarĆ” igual que arriba. Hay otras cuatro representaciones de estado de grabaciĆ³n:
Si la celda estƔ activamente siendo grabada, el subrayado 40 parpadearƔ activƔndose y desactivƔndose.
Una celda grabada se mostrarĆ” con un fondo rojo continuo 42 (Nota: no mostrado en los dibujos).
Una celda de grabaciĆ³n fallida se indicarĆ” mediante una marca fraccionada 44 sobre el tĆ­tulo. Un fallo en la grabaciĆ³n, puede ser el resultado de cinta insuficiente, pĆ©rdida de potencia del VCR, parada antes de la conclusiĆ³n, etc.
En la figura 5 se muestra un icono de vinculaciĆ³n de programas 46. DespuĆ©s de cada actualizaciĆ³n de programaciĆ³n, el sistema de programaciĆ³n examina en los nuevos listados la eventualidad de cualesquiera tĆ­tulos que coincidan con un tĆ­tulo en TĆ­tulos Vinculados (figura 23). Si un tĆ­tulo coincide, serĆ” automĆ”ticamente etiquetado para su grabaciĆ³n. Cuando un programa vinculado es mostrado en la guĆ­a, tendrĆ” dos identificadores: un contorno rojo 40, que indica que el tĆ­tulo ha sido seleccionado para grabaciĆ³n, y un icono de vĆ­nculo 46 anexado al tĆ­tulo, para indicar que este tĆ­tulo fue seleccionado por vĆ­nculo. DespuĆ©s de que un programa vinculado ha sido grabado, se tratarĆ” como cualquier programa grabado, con el tĆ­tulo sombreado en rojo. Para diferenciar esta grabaciĆ³n de otras, el icono de vĆ­nculo permanecerĆ” anexado al tĆ­tulo.
Detalles adicionales en la caracterĆ­stica de vinculaciĆ³n, se da en la pantalla 19 de la figura 23. 1) Un programa vinculado 47 puede ser suspendido por el usuario (quizĆ”s para evitar conflicto con una grabaciĆ³n pendiente), mediante deshacer la selecciĆ³n del tĆ­tulo vinculado, en la pantalla de Lista de VĆ­nculos, bajo el comando Memorizar GrabaciĆ³n. Un programa de vĆ­nculo suspendido, aĆŗn seguirĆ” estando identificado mediante un icono de vĆ­nculo, pero el contorno rojo se suprimirĆ”, puesto que el programa no serĆ” grabado. 2) Un proceso de vĆ­nculo inteligente se emplea, para poner bajo control la coincidencia de tĆ­tulos, cuando hay una probabilidad de demasiados candidatos para ser grabados. El EspectĆ”culo de Lucy, por ejemplo, es a menudo publicado en varios canales. La vinculaciĆ³n descontrolada de Lucy, puede tener por resultado una plĆ©tora de grabaciones. Para tales series, la lista de vĆ­nculos incluirĆ” el canal y la hora, asĆ­ como el tĆ­tulo de vĆ­nculo. Para el caso de aficionados Ć”vidos de Lucy, el usuario puede localizar cada serie individualmente para su vinculaciĆ³n. Si hay mĆ”s de un tĆ­tulo vinculado del mismo nombre, la serie serĆ” numerada, en el orden de adquisiciĆ³n. AsĆ­, la segunda Lucy serĆ” identificada como Lucy (Dos), en 47.
Las figuras 1-3 muestran las columnas 28, encabezadas por indicadores de estado, de encabezado de media hora. La franja del encabezado de 1/2 hora, a travĆ©s de la parte superior de la guĆ­a de TV de cuadrĆ­cula, tiene dos funciones auxiliares: 1) como indicador 48 de grabaciones pendientes, o en progreso, programadas ya en ese momento, y 2) como una barra temporal 50, para delimitar el pasado respecto del futuro. El pasado estĆ” oscurecido, mientras que el futuro estĆ” marcado en tono claro. Si hay una grabaciĆ³n en progreso, el encabezado de 1/2 hora serĆ” contorneado en rojo en 48, del mismo modo que una celda de tĆ­tulo de grabaciĆ³n pendiente 26.
La figura 6 muestra una pantalla 20 de cuadrĆ­cula de programaciĆ³n de televisiĆ³n, con una nota de programa superpuesta 52. Con capacidad de texto limitada en la pantalla de TV, es preferible mostrar tantas lĆ­neas de listados de TV como sea factible. Para manejar notas de programa, que son texto intensivo, se emplea superposiciones 52 segĆŗn demanda. Las superposiciones 52 de notas de programa, pueden incluir cualquiera de las siguientes informaciones, o todas:
\circ
Un gƩnero de programa
\circ
DescripciĆ³n de programa
\circ
Estrellas y personalidades
\circ
AƱo de estreno
\circ
SubtĆ­tulos episĆ³dicos
\circ
DuraciĆ³n del programa
\circ
Tiempo transcurrido del programa
\circ
CrĆ­tica (ClasificaciĆ³n por Estrellas)
\circ
ClasificaciĆ³n (PG, G, etc.)
\circ
Abreviatura de llamada, marcadores de canal
\circ
Leyenda codificada, estƩreo.
Las notas de programa para un programa seleccionado, se superponen sobre la guĆ­a de cuadrĆ­cula, a peticiĆ³n. La nota de programa puede ser alternada en las posiciones activada/desactivada, empleando un comando SELECCIONAR. La nota de programa 52 superpone, y oculta, 3 Ć³ 4 listados de una guĆ­a. Para minimizar la ocultaciĆ³n de la guĆ­a, se usa una nota que ambula automĆ”ticamente. La nota de programa se superpondrĆ”, bien en la mitad superior o bien en la mitad inferior de la pantalla, segĆŗn sea necesario para evitar tapar el tĆ­tulo del listado seleccionado. Si el cursor 32 estĆ” en la mitad superior de la pantalla, la nota aparecerĆ” en la mitad inferior, y viceversa. Si el cursor 32 se mueve a la mitad inferior de la pantalla, la propia nota se posicionarĆ” automĆ”ticamente en la mitad superior de la pantalla.
Las figuras 1-3 y 5-6 muestran una columna de canal 54, en la cuadrĆ­cula 24 de programaciĆ³n de televisiĆ³n. Emisoras favoritas y canales por cable, pueden ser listados juntos, para crear una guĆ­a de cuadrĆ­cula personalizada. La columna de canal 54, a diferencia de la mayorĆ­a de las guĆ­as de TV impresas, tiene una mezcla de nombres de emisoras en el aire, y nombres de servicios por cable.
La guĆ­a de cuadrĆ­cula 24 lista canales mediante combinaciones favoritas de nĆŗmeros de emisora y nombres de cable, y no en el orden alfabĆ©tico usual. Cuando se visualiza la guĆ­a de cuadrĆ­cula 24, estarĆ” representado un comando de SintonĆ­a Arriba/Abajo, del canal, de acuerdo a los canales y al orden listado en la pantalla. Cuando no se estĆ© visualizando la guĆ­a, la secuencia de sintonĆ­a volverĆ” al orden numĆ©rico usual. Cuando se alcanza el Ćŗltimo canal en una pĆ”gina, el comando de siguiente Canal cambiarĆ” el canal, al canal listado al comienzo de la pĆ”gina siguiente.
Cuando un canal en el que estĆ” sintonizado el sintonizador, se muestra en la cuadrĆ­cula 24, se destaca como se muestra en 56. Una pĆ”gina de cuadrĆ­cula 24 puede ser cambiada, bien mediante un comando de pĆ”gina, o bien introduciendo un comando de canal Arriba/Abajo, como se ha descrito arriba. Si se pasa una pĆ”gina usando el comando de pĆ”gina, el canal actual estĆ” ahora localizado en la pĆ”gina anterior, y no se verĆ” en la nueva pĆ”gina. Por lo tanto, la nueva pĆ”gina debe suprimir el destacado de un canal, puesto que este indica el canal actual. NĆ³tese que informaciĆ³n sobre el canal actual estarĆ” aĆŗn presentada en las cajas de informaciĆ³n de canal 58, en la parte inferior de la pantalla.
ĀæCuando se reactivarĆ” el destacado? Ya en la nueva pĆ”gina, el primer comando de canal arriba/abajo, harĆ” que el sintonizador automĆ”ticamente cambie al canal listado en la Ćŗltima o primera fila 30, respectivamente, de la nueva pĆ”gina. Puesto que el canal del sintonizador estĆ” ahora localizado en la nueva pĆ”gina, el canal actual estarĆ” desatacado de nuevo.
Si el destacado de un canal no se suprimiera despuĆ©s de que se seleccione una pĆ”gina, por definiciĆ³n, el sintonizador deberĆ­a cambiar, siguiendo al canal destacado. Esto no es deseable puesto que el paso de pĆ”ginas de forma despreocupada no deberĆ­a hacer que se cambie el canal.
Cuando una guĆ­a es abierta primero, como se muestra en la figura 2, tanto el cursor 32 como el canal actual 56 se sitĆŗan en la misma fila 30 de la cuadrĆ­cula 24. Cuando se cambia el canal 56, es deseable arrastrar el cursor 32 junto con el canal al unĆ­sono. HaciĆ©ndolo asĆ­, el cursor 32 estarĆ” listo para un comando Seleccionar (para recuperar la nota de programa) o para un comando Grabarlo. El arrastre del cursor mediante el comando de canal, tiene lugar siempre que el canal 56 y el cursor 32 estĆ”n unidos en la misma fila. Si no estĆ”n unidos, el cursor 32 se libera del comando de canal. NĆ³tese que el arrastre no es recĆ­proco; mover el cursor 32 no afecta a la selecciĆ³n de canal.
La figura 7 presenta una pantalla 22, que muestra un listado de programas 58 para un solo canal, generado alternando un comando de usuario QuĆ© hay en TV, que cambia entre la cuadrĆ­cula 24 y la lista 58. La lista 58 consiste en filas 60 de listados de programa secuenciales, en el canal, y un campo de informaciĆ³n de canal 62. Las notas de programa se superponen en la lista 58, del mismo modo que se muestra en la figura 6 para la cuadrĆ­cula 24.
Cada comando QuƩ hay en TV, alterna entre la guƭa de cuadrƭcula 24, y la guƭa de filas 58 QuƩ hay DespuƩs en el Canal. Mientras se estƔ visualizando la guƭa de cuadrƭcula 24, el siguiente comando QuƩ hay en TV, remplazarƔ la guƭa de cuadrƭcula 24 con una guƭa 58 de filas de un solo canal. La figura 8 es el diagrama de flujo para el comando QuƩ hay en TV.
La relaciĆ³n de pĆ”ginas entre las dos guĆ­as 24 y 58, estĆ” estrechamente acoplada. La guĆ­a de un solo canal se abrirĆ”, para el canal y horario que estaba seleccionado mediante el cursor 32 en la cuadrĆ­cula 24. Mientras se visualiza la guĆ­a de un solo canal 58, el comando de canal Arriba/abajo serĆ” empleado para cambiar el canal a listar. Cuando se sale de la guĆ­a de un solo canal 58 y se vuelve a la guĆ­a de cuadrĆ­cula 24, el cursor de cuadrĆ­cula 32 apuntarĆ” al canal y el tiempo Ćŗltimos de programaciĆ³n, seleccionados en la guĆ­a de un solo canal 58.
Las figuras 9 a 22 ofrecen ejemplos Ćŗtiles, que ayudan a la comprensiĆ³n de la invenciĆ³n.
Las figuras 9 y 10 muestran superposiciones 64 y 66 estĆ”ticas en el canal, que proporcionan informaciĆ³n de programas actuales cuando se cambia canales mientras se estĆ” mirando la televisiĆ³n. En la superposiciĆ³n 64, cuando se estĆ” examinando canales, el tĆ­tulo de cada programa estĆ” superpuesto en 68, junto con el nombre del servicio de TV (HBO, ABC, etc.), el nĆŗmero del canal de cable, y la fecha actual, dĆ­a de la semana, y hora en el campo de informaciĆ³n de canal 62. La superposiciĆ³n 66 es la misma que la superposiciĆ³n 64, excepto que esta superposiciĆ³n incluye una nota de programa 70, que es similar a la nota de programa 52 en la figura 6, pero contiene informaciĆ³n pertinente al programa que estĆ” actualmente siendo emitido en el canal seleccionado. Para acceder a notas de programa, se presiona el botĆ³n Seleccionar. Adicionalmente a la nota de programa 70, se indica el tiempo transcurrido mediante una barra temporal calibrada en porcentaje 72. La barra estĆ” comprendida entre una S para comienzo (start), y una F para final. Por defecto, los tĆ­tulos aparecerĆ”n automĆ”ticamente cuando los canales son explorados. Los TĆ­tulos estĆ”ticos pueden ser desactivados empleando al botĆ³n CANCELAR. Para restaurar los tĆ­tulos automĆ”ticos, presionar Seleccionar mientras que se estĆ” viendo la TV. El diagrama de flujo que gobierna los tĆ­tulos/ notas de programa, mientras se estĆ” viendo la TV, se muestra en la figura 11.
Una pantalla de grabaciĆ³n urgente 74 se muestra en la figura 12. La pantalla de grabaciĆ³n urgente incluye la siguiente informaciĆ³n:
TĆ­tulo del Programa
DuraciĆ³n del Programa
Tiempo de GrabaciĆ³n Restante
Velocidad de GrabaciĆ³n
La figura 13 muestra una pantalla de Ć­ndice de cinta 76. Localizar un segmento grabado, es a menudo una ardua tarea, cuando han sido grabados varios programas en la cinta. Sin una lista de contenidos, los usuarios del VCR se confunden a travĆ©s de tramos de grabaciĆ³n, intentando encontrar quĆ© estĆ” grabado en la cinta, donde estĆ” el comienzo del programa deseado, y donde estĆ” actualmente la cinta. Algunos VCRs de alta calidad, proporcionan indexados de la cinta que encuentran automĆ”ticamente el comienzo de cada grabaciĆ³n. Sin embargo, si bien el espectador puede encontrar el comienzo de una grabaciĆ³n, los VCRs que indexan no graban tĆ­tulos. El resultado global es, mĆ”s o menos, tan Ćŗtil como tener una tabla de contenidos sin tĆ­tulos de capĆ­tulo. AĆŗn es necesaria considerable tarea de bĆŗsqueda, para encontrar quĆ© estĆ” grabado en cada Ć­ndice.
La pantalla de Ć­ndices de cinta 76 proporciona un directorio de cinta virtual, proporcionando la funciĆ³n equivalente de una tabla de contenidos, para una grabaciĆ³n de cinta. Hay una lista 78 de tĆ­tulos de programas grabados, un puntero 80 al comienzo del programa, y un cursor de indicaciĆ³n de la posiciĆ³n actual 82 que muestra la localizaciĆ³n del "capĆ­tulo" en la cinta. El directorio virtual es compilado automĆ”ticamente, revisado y almacenado en memoria fuera de la cinta, cuando el usuario graba sobre la cinta.
El comando QuĆ© hay en la Cinta, mostrarĆ” una lista de tĆ­tulos de programas grabados en la cinta. El tĆ­tulo del programa seleccionado (el segmento de una cinta que estĆ” posicionado sobre la cabeza de la cinta) se destaca mediante el cursor 82. El puntero de posiciĆ³n de la cinta 80 rastrea dinĆ”micamente la posiciĆ³n actual de la cinta. Toda la bĆŗsqueda se lleva a cabo por tĆ­tulo simplemente, evitando la necesidad de nĆŗmeros de Ć­ndice. El directorio de la cinta es equivalente a una tabla de contenidos que muestra tĆ­tulo, pero no nĆŗmeros de pĆ”gina. Se abre automĆ”ticamente en la pĆ”gina de inicio, simplemente mediante apuntar al tĆ­tulo del programa. Adicionalmente al directorio de la cinta 78 de programas grabados, la pantalla 76 incluye un campo de duraciĆ³n de programa 84, la velocidad grabada de cada campo de tĆ­tulo 86, el tiempo que queda restante en el campo de cinta 88, el tiempo que queda restante en el campo de programa 90, y un campo 92 de la hora de la siguiente grabaciĆ³n programada.
El directorio de cinta virtual se genera como sigue. Es difĆ­cil implementar un directorio de cinta que sea completo en si mismo, para un almacenamiento de acceso no aleatorio, tal como una cinta de vĆ­deo. Independientemente de donde este almacenado el directorio en la cinta, el tiempo de acceso latente para localizar el directorio, y volver a la posiciĆ³n actual (para una cinta estĆ”ndar de seis horas) es de una lentitud atroz, del orden de 6 a 10 minutos.
Si se graba directorios redundantes, de modo uniforme a travĆ©s de la cinta, para minimizar el tiempo de latencia, el problema de lentitud simplemente se desplaza, de la reproducciĆ³n a la actualizaciĆ³n de mĆŗltiples directorios. DespuĆ©s de grabar cada programa de vĆ­deo, toda la cinta debe ser examinada para actualizar cada directorio. Incluso si este proceso de actualizaciĆ³n se automatiza, hay una pregunta en relaciĆ³n al excesivo desgaste de las cintas y el propio VCR. A saber: cada grabaciĆ³n, independientemente de lo corta que sea, tiene por resultado exploraciĆ³n de alta velocidad de toda la cinta, para revisar todos los directorios.
Incluso mĆ”s problemĆ”tica es la cuestiĆ³n de cuando llevar a cabo la actualizaciĆ³n, puesto que no hay periodo "de seguridad" para que el VCR tome el control. Por ejemplo, el usuario puede haber parado la cinta momentĆ”neamente, quizĆ”s para saltar los anuncios, solo para encontrarse con que el VCR ha requisado el control, y ha puesto la cinta en un modo de alta velocidad. La actualizaciĆ³n mĆ”s segura es una que sea iniciada por el usuario. Desafortunadamente, pocos usuarios de VCR seguirĆ”n un procedimiento reglamentado de actualizaciĆ³n despuĆ©s de cada sesiĆ³n de grabaciĆ³n. Claramente, un directorio en la cinta, basado en tecnologĆ­a existente, no es satisfactorio.
La siguiente soluciĆ³n innovadora, el "directorio de cinta virtual", almacena informaciĆ³n del directorio en memoria fuera de la cinta, y no necesita un directorio en la cinta, ni ninguna sofisticaciĆ³n de la cinta de vĆ­deo. Puesto que el directorio estĆ” soportado en memoria externa, en lugar de estar en la cinta, es mĆ”s adecuado para cintas que han sido recientemente reproducidas y grabadas, las "cintas de trabajo".
Cuando se graba un programa, el tĆ­tulo del programa se escribe en el canal de datos (pista de control) de la cinta y, al mismo tiempo, es almacenado en una memoria no volĆ”til (NV). Otra informaciĆ³n sobre el programa grabado, tal como la longitud del programa, categorĆ­a del tema, fecha de grabaciĆ³n, y cĆ³digo identificador de la cinta, puede ser escrita en el canal de datos, asĆ­ como almacenada en la memoria NV. La memoria NV es adecuada para mantener un nĆŗmero de cintas de trabajo.
Cuando se graba una cinta por primera vez, el canal de datos de la cinta serĆ” explorado durante unos pocos segundos, para identificar el programa grabado bajo la cabeza de la cinta. Estos datos serĆ”n comparados con los directorios almacenados en la memoria NV. Si hay una coincidencia, el directorio de la cinta de trabajo se mostrarĆ” inmediatamente, cuando al botĆ³n QuĆ© hay en la Cinta sea presionado. El directorio "virtual" de la cinta parece haber sido leĆ­do de la cinta, pero realmente se obtiene de la memoria NV.
Si no hay ninguna coincidencia, se crearĆ” un nuevo directorio para la cinta. Durante la reproducciĆ³n y la grabaciĆ³n de esta cinta, se generarĆ” un directorio virtual para esa cinta. Los directorios de cintas inactivas serĆ”n automĆ”ticamente eliminados de la memoria, segĆŗn se introduce nuevas cintas de trabajo.
Es relativamente sencillo estimar el tiempo restante del programa de televisiĆ³n que ha sido programado, con la ayuda de un reloj y una programaciĆ³n de TV. Por el contrario, hay pocos indicios para la localizaciĆ³n actual durante la reproducciĆ³n de un programa grabado, en particular cuando hay varios segmentos grabados en una cinta. Contadores de Ć­ndice de la cinta, o relojes de tiempo de funcionamiento, necesitan de una contabilidad diligente antes del comienzo de un segmento grabado. Pocos consumidores intentarĆ”n la dudosa tarea de restaurar nĆŗmeros de 5 o 6 dĆ­gitos cuando se proporcione un indicador "burdo", tal como "ĀæestĆ” el programa prĆ³ximo a su tĆ©rmino?", o "Āæcuando comienza aproximadamente el siguiente segmento?". Claramente, existe la necesidad de proporcionar un indicador de localizaciĆ³n sin la carga de la contabilidad.
Para proporcionar un indicador de la localizaciĆ³n relativa de la cinta, de un vistazo, ha sido ideado un medidor 94 de posiciĆ³n de la cinta en pantalla. El medidor de la posiciĆ³n de la cinta 94, consta de una barra vertical 96 con el puntero de flecha 80, localizado en el borde izquierdo de la pantalla 76. La flecha 80 rastrea dinĆ”micamente la actual posiciĆ³n, cuando la cinta es adelantada o rebobinada.
El medidor 94 estƔ graduado, no en unidades lineales, sino en unidades de segmentos grabados 98, con cada segmento etiquetado con su tƭtulo de programa. Asƭ, un programa de 10 minutos, o un programa de 6 horas, estƔ representado como una unidad vertical que corresponde a la anchura de un segmento 98. Sin embargo, el medidor 94 es lineal dentro de cada segmento 98. Si la flecha apunta al 25% superior del segmento de programa 98, esto indica que la cabeza de la cinta estƔ posicionada sobre el primer 25% del programa. Si se mostrase un medidor lineal convencional, se necesitarƭa un medidor mucho mƔs complicado, que podrƭa probablemente confundir mƔs bien que clarificar.
AsĆ­, este medidor de cinta 94 proporciona una rĆ”pida y concisa indicaciĆ³n sobre donde estĆ” actualmente posicionada la cabeza de la cinta, en relaciĆ³n al programa actual, y en relaciĆ³n a otros programas en la cinta, y el tĆ­tulo de otros programas.
La pantalla de Ć­ndice de la cinta 76, incluye un campo indicador de movimiento de la cinta 100. Cuando la cinta es sometida a un nuevo posicionamiento, a alta velocidad, se mostrarĆ” la pantalla Que hay En Esta Cinta (WOT (What's On This Tape)) 76. Durante la bĆŗsqueda a alta velocidad de un programa largo, el medidor de cinta 94 parecerĆ” estar inactivo, puesto que el medidor es relativamente grueso para programas de larga duraciĆ³n. Para suplir al medidor de cinta 94, se incluye el indicador de cinta 100. Durante posicionamiento de alta velocidad, uno de estos mensajes se mostrarĆ” en el espacio sobre el icono de cinta de centro doble 102: REPRODUCIR, GRABAR, ADELANTAR, INVERTIR, PAUSA, y PARAR.
REPRODUCIR, se muestra mientras que la cinta estĆ” llevando a cabo un nuevo posicionamiento en el tĆ­tulo seleccionado. Cuando se alcanza el tĆ­tulo, la pantalla WOT 76 serĆ” remplazada por la reproducciĆ³n del vĆ­deo. GRABAR, se muestra mientras que la cinta se estĆ” posicionando en el segmento del programa seleccionado 98, donde se escribirĆ” la nueva grabaciĆ³n.
Las figuras 14-17 muestran pantallas de funciĆ³n por Temas 104. La funciĆ³n Tema permite al espectador, clasificar rĆ”pidamente la programaciĆ³n transferida, y mostrar un subconjunto de programaciĆ³n en base a un tema de interĆ©s. El usuario tiene la libertad para seleccionar listados clasificados, primero por temas principales, segundo por tema(s) dentro de un tema principal, y/o por calificadores de tema. Todas las guĆ­as clasificadas por tema principal, tema, y calificador, se mostrarĆ”n en un formato de filas tabuladas, y comienzan listando los programas mĆ”s cercanos a la media hora actual. Las pantallas de la funciĆ³n tema 104 tienen los siguientes atributos:
Temas principales Rotatorios. Hay cuatro categorĆ­as de tema principal, con cada tĆ­tulo de tema principal encerrado en cajas de selecciĆ³n 106 horizontalmente dispuestas. De izquierda a derecha, los temas son:
[PelĆ­culas] [Deportes] [Especiales] [TV de Pago]
La figura 18 es un diagrama que define el comando Tema principal.
SelecciĆ³n de Tema. Hay hasta 16 temas 108, para cada tema principal, dispuestos en una imagen de 8 filas por dos columnas 110. Puede ser seleccionado cualquier nĆŗmero de temas, bajo un tema principal seleccionado. Los temas son una funciĆ³n lĆ³gica O, lo que quiere decir que cada listado que encuentra la definiciĆ³n del tema serĆ” mostrado. Por ejemplo si bajo el tema principal de PelĆ­culas, se selecciona, como tema, los tĆ­tulos de Comedia y SĆ”tira, se mostrarĆ” un subconjunto de la programaciĆ³n de tanto pelĆ­culas de comedia como pelĆ­culas de sĆ”tira.
SelecciĆ³n Todo por defecto. Al principio de abrirse la pantalla Tema principal 104, se destacarĆ” el primer segmento (tema 108 superior y mĆ”s a la izquierda). Esta es la funciĆ³n TODO, que es la suma de todos los temas 108 para el tema principal seleccionado. La funciĆ³n TODO fue creada para minimizar la pulsaciĆ³n de botones. Sin una categorĆ­a de todos los temas, el usuario debe activar todos los 16 temas 108 individualmente. A la inversa, si el usuario desea ir desde una pantalla de todos los temas un tema individual, el usuario debe llevar el cursor a, y deshacer la selecciĆ³n de, cada uno de los otros 15 temas.
Calificadores. Cada tema principal incluye un grupo de atributos de bĆŗsqueda o calificadores 112. Los calificadores para cada tema principal 106, se muestran respectivamente en una de las figuras 14-17, para cada tema principal 106. Puede ser activado a la vez cualquier nĆŗmero de calificadores. Estos calificadores llevan a cabo funciones lĆ³gicas O; seleccionarĆ”n o mostrarĆ”n todos los listados (clasificados primero por tema principal y tema) que satisfacen los calificadores.
Los calificadores 112 estĆ”n posicionados para una selecciĆ³n fĆ”cil. La selecciĆ³n de calificadores se hace usando los comandos de cursor usuales. Cuando un tema principal 106 es abierto inicialmente, por defecto, el cursor estĆ” localizado cerca de la parte superior de la pantalla. Para minimizar los comandos de cursor, los calificadores estĆ”n tambiĆ©n localizados cerca de la parte superior de la pantalla. Por el contrario, situar los calificadores en la parte inferior de la pantalla, requerirĆ­a un recorrido de ida y vuelta de hasta 16 pulsaciones de botĆ³n.
La estrategia de clasificaciĆ³n de tema principal competa se define como sigue:
Listados = (Tema A + Tema B + etc.) * (Calificador A + Calificador B + etc.)
Esto puede leerse como, listar todos los Tema A que tambiĆ©n cumplan Calificador A o Calificador B, mĆ”s todos los Tema B que tambiĆ©n cumplen Calificador A Ć³ Calificador B, etc.
Calificadores, temas y temas principales, estĆ”n basados en operaciones con bases de datos relacionales, y permiten la clasificaciĆ³n lĆ³gica de la programaciĆ³n. Para soportar este orden superior de clasificaciĆ³n, deben ser distribuidos datos adicionales, al VCR. Por el contrario, operaciones sencillas de clasificaciĆ³n, tal como clasificaciĆ³n por tiempo y por canal, son inherentes a la informaciĆ³n fundamental de una guĆ­a de TV, y no necesitan datos de bĆŗsqueda
auxiliares.
Las secuencias de pulsaciones de tecla para usar la pantalla de temas 104 son como sigue: Mientras se estĆ” mirando la TV, el primer comando de tecla de Tema principal, llevarĆ” a la pantalla inicial de tema principal, a remarcar el tema de mĆ”s a la izquierda, PelĆ­culas. Comandos adicionales de tema principal, rotarĆ”n la selecciĆ³n de tema principal de izquierda a derecha. Cada pantalla de tema principal, se iniciarĆ” con la selecciĆ³n de TODOS (los temas). Si no se hace selecciĆ³n de tema, se mostrarĆ” una guĆ­a de todos los temas, para el tema principal seleccionado, tras pulsar el comando Seleccionar/Ir a.
Para clasificar adicionalmente el tema principal por un solo tema, se posiciona el botĆ³n cursor en el tema deseado, y se presiona el botĆ³n Seleccionar/Ir a. ƚsese el cursor para volver a un tema.
Para clasificar mĆ”s de un tema, posicionar el cursor sobre cada tema deseado, y presionar el botĆ³n Seleccionar. Cuando se ha terminado, pĆŗlsese Seleccionar/Ir a, para mostrar una guĆ­a de mĆŗltiples temas.
Para clasificar por uno o mĆ”s atributos, posicionar el cursor sobre cada atributo deseado y presionar al botĆ³n Seleccionar. Cuando se haya terminado, muĆ©vase el cursor a un tema y presiĆ³nese Seleccionar/Ir a, para recibir la guĆ­a de TV clasificada por tema principal/atributo.
Aparte de la grabaciĆ³n urgente, todas las actividades de grabaciĆ³n estĆ”n controladas con la pantalla Memoria de GrabaciĆ³n 16 de la figura 4. A la pantalla de Memoria de GrabaciĆ³n 16, se accede con un botĆ³n de Memoria de GrabaciĆ³n. Cuando se pulsa el botĆ³n de Memoria de GrabaciĆ³n, aparecerĆ”n los siguientes tĆ­tulos, encerrados en cajas de selecciĆ³n dispuestas horizontalmente 114, en la parte superior de la pantalla de apertura. De izquierda a derecha:
[Grabaciones Pendientes] [Programas Grabados] [TĆ­tulos Vinculados] [ProgramaciĆ³n en CuadrĆ­cula]
Cada comando de botĆ³n de Memoria de GrabaciĆ³n, destacarĆ” una nueva selecciĆ³n, rotando de izquierda a derecha, y abarcando hasta Grabaciones Pendientes despuĆ©s de la posiciĆ³n mĆ”s a la derecha. La figura 19 es un diagrama de flujo que define el comando Memoria de GrabaciĆ³n.
La figura 20 muestra una pantalla de PersonalizaciĆ³n de Canal 116. La pantalla 116 permite al usuario personalizar canales, en correspondencia con el interĆ©s de visualizaciĆ³n, proporcionar un listado compacto, asĆ­ como eliminar canales no deseados durante la exploraciĆ³n arriba y abajo. Durante la actualizaciĆ³n de la programaciĆ³n, tambiĆ©n se distribuye al VCR una lista de todos los canales por cable disponibles en el sistema de cable del abonado (o estaciones de emisiĆ³n para abonados en el aire). Este conjunto completo de canales, puede personalizarse usando la pantalla
116.
La pantalla de personalizaciĆ³n de canal 116 tiene dos imĆ”genes, una imagen de 3 columnas 118, que lista hasta 36 canales completos, y una imagen de una sola columna 120 que lista 12 canales favoritos MƍOS. La Ćŗltima es una rĆ©plica de la columna 122 descriptora de canal (figura 1), de la guĆ­a de cuadrĆ­cula, de apertura. Las pĆ”ginas adicionales estĆ”n disponibles (empleando el botĆ³n pĆ”gina, para alternar entre pĆ”ginas), para acomodar sistemas con mĆ”s de 36 canales. Cada celda 124 en la imagen de 3 columnas 118, contiene la siguiente informaciĆ³n: nĆŗmero de Canal, y nombre de servicio de programa (tal como HBO o emisora KTVU, 2). El color de la celda 124 estĆ” codificado, para indicar los siguientes estados:
ACTIVADO, estado por defecto antes de ninguna personalizaciĆ³n, con la celda 124 con fondo verde claro.
MƍOS, canales favoritos listados en la imagen de una sola columna 120, tambiĆ©n mostrado en el campo de tres columnas 118, con un fondo azul.
DESACTIVADO, un canal borrado de todas las guĆ­as, asĆ­ como durante le exploraciĆ³n de Canal Arriba/Abajo (aĆŗn accesible empleando el teclado numĆ©rico de canal, de diez teclas). Las celdas DESACTIVADO tienen un fondo gris.
Cuando se instala por primera vez, el sistema asigna los primeros 12 (listados en orden numĆ©rico) canales MƍOS como favoritos. El estado de canal puede ser cambiado seleccionando un canal y eligiendo un estado, MƍOS, ACTIVADO, o DESACTIVADO, empleando el botĆ³n SELECCIONAR.
Puesto que solo se permite 12 favoritos, el usuario debe retirar primero un canal favorito, cambiando el estado de un canal favorito existente a ACTIVADO, o a DESACTIVADO. Cuando esto se ha hecho, la primera columna despejarĆ” automĆ”ticamente un espacio, para la siguiente selecciĆ³n MƍOS. Cuando un nuevo MƍOS es seleccionado, la columna MƍOS 120 insertarĆ” automĆ”ticamente la nueva selecciĆ³n en el orden prescrito. El orden de listado en la columna 120 de canal favorito MƍOS, es como sigue:
todas las estaciones de emisiĆ³n favorita serĆ”n listadas primero en orden numĆ©rico. DespuĆ©s, todos los servicios de cable serĆ”n listados en orden alfabĆ©tico.
Un nuevo servicio de cable, que desplaza un servicio previo, serĆ” insertado bajo el estado previo. Ejemplo: si el canal era MƍOS, el nuevo servicio serĆ” MƍOS. Sin embargo, un nuevo servicio de cable que aparezca en un nuevo canal, serĆ” configurado inicialmente ACTIVADO.
La figura 21 muestra un panel frontal 130, para un controlador a distancia de un sistema de programaciĆ³n. La mitad superior del panel delantero 130, corresponde a un controlador a distancia convencional, para un conjunto de televisiĆ³n y VCR. EstĆ” incluido un teclado numĆ©rico de diez teclas de funciĆ³n dual 132, con la funciones alternas, de cada botĆ³n y su dĆ­gito mostrado, un botĆ³n de alternancia TV/VCR 134, botones, de volumen y de canal, arriba/abajo 136, y botones de control del VCR 138. La mitad inferior del panel frontal 130 contiene botones de control, que son especĆ­ficos del sistema de programaciĆ³n. EstĆ”n incluidos un botĆ³n QuĆ© Hay en la Cinta 140, un botĆ³n QuĆ© Hay en TV 142, un botĆ³n Tema principal 144, un botĆ³n Memoria de GrabaciĆ³n 146, un botĆ³n Grabarlo 148, un botĆ³n Vincularlo 150, un botĆ³n Ayuda/MenĆŗ 152, un botĆ³n Seleccionar/Ir a 154, Izquierda, Derecha, Arriba, Abajo, botones de Cursor de PĆ”gina 156, un botĆ³n Volver TV/VCR 158, y un botĆ³n Cancelar/Deshacer 160. El uso de estos botones, bien ha sido explicado arriba, o bien es evidente a partir de sus etiquetas.
Las figuras 22A y 22B son diagramas de bloque, de sistemas de programaciĆ³n de televisiĆ³n/controladores de cinta 180 y 182, en los que se usa en interfaz de usuario. El sistema de programaciĆ³n/controlador 180, es aplicable a un equipo de televisiĆ³n existente, donde el sistema de programaciĆ³n estĆ” separado del equipo de televisiĆ³n bĆ”sico. El sintonizador programable 202 se muestra como parte de un descodificador de cable. El sistema de programaciĆ³n/controlador 182, se muestra como integrado en un VCR 211. En esta versiĆ³n, no se necesita un descodificador de cable, y el sintonizador 207 es parte del VCR 211. DeberĆ­a quedar claro, a partir de estos dos sistemas 180 y 182, que el controlador de programaciĆ³n/cinta puede estar integrado en otro equipo de televisiĆ³n, tal como un descodificador de cable, o un receptor de TV/Monitor. TambiĆ©n es prĆ”ctico implementar todo el controlador de programaciĆ³n/cinta, en un controlador a distancia, aƱadiendo una visualizaciĆ³n de texto, tal como una pantalla LCD, en el controlador a distancia 212.
En el sistema 180, el sintonizador programable 202, que puede ser parte de una unidad de decodificaciĆ³n de cable, recibe una seƱal de TV desde la antena 200, y/o desde la entrada de cable 205. La salida del sintonizador 216, va al descodificador de intervalo de borrado vertical (VBI (vertical blanking interval)) 222, que puede ser un descodificador de tĆ­tulo cerrado, o un descodificador de teletexto de alta velocidad. La informaciĆ³n de listados, y otra informaciĆ³n de soporte tal como datos de asignaciĆ³n de canal de cable, serĆ”n transmitidos sobre el VBI, por una o mĆ”s estaciones locales o canales por cable, varias veces al dĆ­a o continuamente.
Cuando se requiere una actualizaciĆ³n, el sintonizador programable 202 se sintonizarĆ” automĆ”ticamente a la emisora, o al canal por cable, que lleve los datos. DespuĆ©s de que la seƱal VBI es procesada por la CPU 228, los datos del listado son almacenados en memoria de programaciĆ³n 232, mientras que los datos de asignaciĆ³n de canal de cable se almacenan en memoria RAM especĆ­fica para cable 238. Estos datos son empleados para convertir nombres de fuentes de TV genĆ©ricos, tal como HBO, a asignaciones de canal por el sistema de cable especĆ­fico.
Otra informaciĆ³n transmitida al controlador de programaciĆ³n/cinta, y almacenada en la memoria RAM del sistema 240, incluye datos de actualizaciĆ³n del reloj, para ajustar el reloj del sistema 230 automĆ”ticamente, tiempo de actualizaciĆ³n de programaciĆ³n, que puede variar desde un formato de vez al dĆ­a, a uno transmitido continuamente, nuevas categorĆ­as de tema, y datos de cambio de programaciĆ³n del Ćŗltimo minuto.
Para una solicitud QuĆ© hay en TV, el listado almacenado en la memoria de programaciĆ³n 232, es recibido, procesado por la CPU 228, y sacado al generador de visualizaciĆ³n de vĆ­deo 224. El conmutador de vĆ­deo 226 es activado por la salida de la CPU 246, para seleccionar la salida del generador de visualizaciĆ³n de vĆ­deo 224, siempre que vayan a ser presentados al monitor/TV 210 datos de programaciĆ³n.
Cuando se hace una solicitud para grabaciĆ³n desplazada en el tiempo, el tĆ­tulo del programa y sus parĆ”metros de grabaciĆ³n (canal, hora de inicio y duraciĆ³n) son copiados, desde la memoria de programaciĆ³n 232, a la Memoria de GrabaciĆ³n RAM 236. Cuando el reloj del sistema 230 se corresponda con el tiempo programaciĆ³n, la CPU 228 emitirĆ” un comando de canal al sintonizador programable del descodificador de cable 202, y un comando de encendido y grabaciĆ³n al VCR 206, por medio de un dispositivo a distancia emisor de infrarrojos 214, dirigido a los puertos de entrada de infrarrojos de estos dos dispositivos. En la versiĆ³n de VCR integrado 182, el comando al sintonizador 207 se hace en un bus inalĆ”mbrico 264.
Adicionalmente a programar mediante selecciĆ³n de un tĆ­tulo, a partir de los datos en pantalla de la programaciĆ³n, tambiĆ©n es posible programar el VCR 206, o 211, y el descodificador de cable 202, o 207, con el controlador a distancia 212. De este modo, la informaciĆ³n de programaciĆ³n se introduce en el controlador a distancia 212 y, en el momento necesario, el controlador a distancia 212 emitirĆ” el comando de programaciĆ³n al dispositivo de TV adecuado. Si bien hay muchos controladores a distancia universales que ofrecen la capacidad de programar, ninguno permite al usuario introducir nombres genĆ©ricos, tal como nombres de emisora y canal de cable, ni la CPU convierte los nombres a canales especĆ­ficos para sintonizar el VCR , o el descodificador de cable. Esto se implementa incorporando la CPU 228, y la RAM especĆ­fica para cable 238, en el controlador a distancia 212.
En controlador a distancia 212, y el dispositivo remoto emisor de infrarrojos 214, son capaces de emular las instrucciones de comando de infrarrojo necesarias para el descodificador de cable 202, y el VCR 206. Los cĆ³digos de emulaciĆ³n de comando para el dispositivo remoto 214, son almacenados en memoria RAM/ROM 239 de cĆ³digos de IFR para el descodificador de cable. Los comandos para descodificadores de cable populares y VCRs, estĆ”n previamente programados en ROM. Alternativamente, puede conocerse los comandos infrarrojos del controlador a distancia original, con la ayuda de controladores en el receptor de entrada de IFR 264, y almacenar los cĆ³digos de comando en memoria RAM 239 despuĆ©s de su procesamiento por la CPU 228. Este proceso es bien conocido en el arte de controladores a distancia universales, y no necesita ser detallado aquĆ­.
Como se muestra en la figura 22A, el VCR 206 y el descodificador de cable 202, pueden ser controlados manualmente mediante el controlador a distancia 212, o pueden ser controlados automƔticamente por un dispositivo remoto emisor de infrarrojos 214.
Durante la grabaciĆ³n, la localizaciĆ³n del Ć­ndice de la cinta, del VCR 206, serĆ” transmitida sobre el bus de control/datos 270, a la CPU 228. Esta informaciĆ³n de la direcciĆ³n de inicio, se almacena en memoria RAM del directorio de la cinta 234, junto con el tĆ­tulo del programa. El bus 270 transporta tambiĆ©n comandos de control del VCR, para grabar, reproducir, selecciĆ³n del sintonizador, y otras funciones, incluido encender/apagar.
Una vez que se graba un programa, su tĆ­tulo y otra informaciĆ³n del programa se almacena en una secciĆ³n de la memoria RAM para Memoria de GrabaciĆ³n 236. Para reproducir un programa grabado, la solicitud QuĆ© hay en la Cinta, harĆ” que se muestre un directorio de programas grabados en la cinta. Cuando un programa es seleccionado, para reproducir desde este directorio, la cinta harĆ” un avance, o un rebobinado, rĆ”pido, hasta la localizaciĆ³n del Ć­ndice de cinta especificado en la memoria RAM del Directorio de la Cinta 234.
En el sistema 182, el controlador de programaciĆ³n/cinta 220 estĆ” subsumido en el VCR 211. El mecanismo de cinta del VCR 252 contiene toda la electrĆ³nica de grabaciĆ³n y reproducciĆ³n del grabador de vĆ­deo, menos el sintonizador programable 207. Los datos grabados en la pista de control de una cinta, se acoplan a la CPU 228 sobre el bus de entrada 258 y el bus de salida 256. El arte de grabar datos en la pista de control es bien conocido, por ejemplo, en VCRs recientes con capacidad de indexaciĆ³n. Se transporta comandos de CPU 228, al VCR 211, sobre el bus 254. Cuando informaciĆ³n de programaciĆ³n va a ser mostrada, la entrada de control al interruptor del vĆ­deo 246, selecciona el generador de visualizaciĆ³n en la lĆ­nea 218. En otras ocasiones, el interruptor del vĆ­deo 226 selecciona la salida del mecanismo de VCR 252, en la lĆ­nea 250.
Desde el VBI puede ser transferida informaciĆ³n de programaciĆ³n. Alternativa o suplementariamente, puede ser transferida desde una lĆ­nea de telecomunicaciĆ³n 270 al mĆ³dem 268, y a la CPU 228, por vĆ­a de la lĆ­nea 266. Pueden ser empleados otros medios de distribuciĆ³n de informaciĆ³n de programaciĆ³n, incluido el uso de un canal portador secundario en el servicio de cable.
DeberĆ­a ahorra ser manifiesto, fĆ”cilmente para aquellos cualificados en el arte, que ha sido proporcionado un sistema, y mĆ©todo, que incorpora un nuevo interfaz de usuario, capaz de lograr los objetivos expuestos de la invenciĆ³n. El interfaz de usuario que estĆ” configurado para compensar la naturaleza particular de la informaciĆ³n de programaciĆ³n de televisiĆ³n. El interfaz de usuario tiene un funcionamiento de cursor, que compensa un formato de cuadrĆ­cula irregular, de la informaciĆ³n de programaciĆ³n de televisiĆ³n. El interfaz de usuario presenta la informaciĆ³n de programaciĆ³n en un formato, que compensa la resoluciĆ³n limitada de la pantalla de televisiĆ³n. El interfaz de usuario presenta informaciĆ³n de programaciĆ³n suplementaria, en superposiciones que ocultan una cantidad mĆ­nima de otra informaciĆ³n Ćŗtil. El orden de presentaciĆ³n de la informaciĆ³n de programaciĆ³n en el interfaz, se puede personalizar segĆŗn las preferencias del usuario.
