【Example】
Hereinafter, a television apparatus with a memory function as an embodiment to which a receiving apparatus and a method content recording method according to the present invention are applied will be described with reference to FIGS. 1 to 6.
[0020]
First, the configuration and operation of a television apparatus with a memory according to the present invention will be described with reference to the conceptual diagrams showing the embodiment of FIGS.
FIG. 1 shows an example of a broadcasting station center on the broadcast transmission side. Reference numeral 1 in FIG. 2 denotes a television device with a memory according to the present invention, and reference numeral 2 denotes a remote control unit. The broadcast station center of FIG. 1 is collected by a broadcast camera 101 that normally transmits information from a production station or a relay station, a video server 102 that plays a role of a data bank, and a video server 103 that is a data bank of a movie distribution company. These pieces of information are temporarily collected in the transmitting device 104.
[0021]
The broadcast signal in the transmission device 104 is a normal program A such as sports, news, quizzes, and commercials, regional information B, book materials C that can be freely viewed by the user, and services such as home medical care. Medical registration D, home shopping E, game F, TV guide G that provides program software information for television broadcasting, karaoke H, message advertisement J as a means of transmitting information between users and local community information, movie software K, etc. All of these broadcast signals are added with an ID code such as time information and category contents by an ID code generator 105 and edited by a video editing device 106, and then are transmitted by a terrestrial or broadcast satellite 107, a coaxial cable, or the like. The data is transmitted to each user via the optical cable 108.
[0022]
In the television device 1 with a memory shown in FIG. 2, a broadcast signal is received by a tuner 7 via a receiving antenna 5 for receiving a broadcast signal or a CATV receiver 6. Digital broadcast signals and current analog broadcast signals are input to the program selector 8. The program selector 8 selects a broadcast signal under the control of the system controller 10 to obtain designated data.
[0023]
When the broadcast signal is an analog broadcast signal, the broadcast signal is transmitted to the encoder 9 for encoding each data of the MPEG2 system (or MPEG2 video, MPEG2 audio), for example. The encoder 9 performs an encoding process for encoding the input analog broadcast signal into a recording format that matches the large-capacity memory 11. However, since the digital broadcast signal does not need to be encoded, the digital broadcast signal is processed as a digital broadcast signal without being processed by the encoder 9 and transmitted to the large-capacity memory 11 for recording.
[0024]
The television apparatus 1 with a memory includes a ROM / RAM 11A, which is a large-capacity memory 11, a primary memory 11B, a secondary memory 11C, and a drive unit 16 for driving the user replacement disk 4, which are mounted therein.

The large-capacity memory 11 has an automatic selection mode and a multiple selection mode. The recording capacity can be set freely. These selections are made on the remote controller 2 or the operation unit (not shown) of the television device with memory of the present invention, and the results are displayed on the display unit 3.
[0027]
Further, the system controller 10 performs the following operation which is the main point of the present invention. In other words, the format configuration (not shown) of the broadcast signal transmitted from the broadcast station center is a packet including at least a header section and a broadcast signal section in which necessary information for recording broadcast content is recorded in advance. This packet is transmitted so as to be always present at the head of the broadcast content. A category code or the like for searching for broadcast content is added to the header portion and transmitted. The category code added to the broadcast content is decoded and read by the program ID detection 12, and is read via the switch control 13. , Are classified into predetermined category areas in the program selector 8. As an example, broadcast contents categorized into news, sports, movies, and the like are stored in the large-capacity memory 11 after being encoded by the encoder 9.
[0028]
The recording capacity for each category in the large-capacity memory is divided in advance into a predetermined time unless otherwise specified by the user. For example, it is determined that the news is 2 hours, the weather forecast is 0.5 hours, and the movie is 6 hours. When the broadcast content exceeds the memory capacity determined in advance, the oldest recorded content is sequentially deleted, and the recorded content of the large-capacity memory 11 is updated using a FIFO function for recording new broadcast content.
[0029]
The recorded content of the large-capacity memory 11 is subjected to decoding processing such as decompression by the decoder 14 and is restored as a composite Video signal or RGB component signal. Based on the control information of the switch control 18, the CRT or the CRT is output via the switch / IO 15. It is displayed on the display unit 3 such as a liquid crystal display device. In addition, the television set 1 with a memory is provided with a telephone line 16 so that payment for a pay broadcast or the like can be automatically performed from a user's bank account. Further, the receiving unit 17 performs decoding according to the control format transmitted from the remote control unit 2 and is processed by the system controller 10.
[0030]
The large-capacity memory that may be incorporated in the television device with memory according to the present invention is a solid-state memory such as a semiconductor memory whose capacity is increasing as a primary memory, and an optical disk is incorporated as a secondary memory.

[0031]
FIG. 3 shows an outline of the remote control unit 2, an infrared light emitting unit 20 which emits radio waves or infrared rays on which various control signals necessary for operating the television apparatus with memory 1 of the present invention are superimposed, and the television with memory. It comprises an LCD panel section 21 for displaying the control information of the apparatus 1 in a hierarchical structure and displaying the current operating point in color as necessary, and a cross key 22 and a trackball 23 as operation sections. . The cross key 22 and the trackball 23 of the remote controller 2 are operated by operating the button of the cross key or operating the trackball 23 from a menu screen displayed on the display unit 3 of the television device 1 with a memory, and The category area is selected by moving the attention item. In addition, it is used to check the remaining memory capacity and to check the video shelf in the memory. The same content as the display on the display unit 3 of the television device with memory 1 can be displayed on the LCD panel unit 21 of the remote control unit 2 by a predetermined instruction together with various control information.
[0032]
Next, a display example of the menu screen of the present invention will be described with reference to FIG.
The recorded contents classified and recorded in the category area in the large-capacity memory 11 for each category are displayed on the display unit 3 as icons on the menu screen. When the user selects a desired category area, for example, with the trackball 23 of the remote controller 2, a pointer 30 (instruction mark) appears on the display unit 3, and clicks on a predetermined location of the trackball 23 or the cross key 22. The category area is determined.
[0033]
The latest recorded contents of the determined category area are immediately displayed on the display unit 3 of the television device with memory 1 so that the user can view the latest information recorded in the category area. The latest information is always stored in the category area by the FIFO operation. For example, assuming that the user has selected and confirmed the news 31, the reproduction of the latest information recorded in the large-capacity memory 11 of the television device with memory 1 is started from the beginning.
[0034]
The menu screen has a hierarchical structure, and menu display of a plurality of category areas can be easily performed. The icon display section of the menu screen is changed to an icon by the user's selection, and the recorded contents of each category area can be viewed as a so-called diagonal reading as a still image or a partial moving image.
[0035]
When the wastebasket 32 is selected and confirmed by the pointer 30, the currently viewed recorded content is deleted at that time, and the content is deleted from the large-capacity memory 11 of the television device 1 with memory.
[0036]
Conversely, when the video shelf 33 is selected, the broadcast content is stored at the time in the user area provided in the large-capacity memory by going back to the beginning of the program. At this time, the menu screen of the display unit 3 changes, and the display is displayed as if it were a video shelf, and the title (or still image) of the broadcast content is added and organized. Another function is to display the latest playback information of the category area on a small screen that can be enlarged / reduced to a large screen while displaying the current broadcast as it is, or to display the current broadcast and playback information on a multi-screen of two or more screens. It can also be displayed. The reproduction speed of the latest reproduction information in the category area can be freely changed by a remote controller.
[0037]
Further, the ID signal allocation according to the present invention will be described with reference to FIG.
FIG. 3 shows an example of a program ID added to the header of a digital broadcast signal and transmitted. The configuration of this ID signal allocation is roughly divided into a program ID 40, a recording control 41, and a broadcast program 42. The program ID 40 contains necessary information for retrieving the broadcast contents. The recording control ID 41 is inserted at the start position and the end position of the broadcast program 42. A signal, a control signal for ending recording, and a control signal for instructing rewinding after recording are inserted.
[0038]
As for the category content L in the program ID 40, for example, the broadcast program 42 received with an ID code such as “0011” has a news category with the last “11”. The program content M is data used when the program selector 8 selects a program, and is information on what broadcast program is currently being received and in what broadcast form. In the configuration, header information, a program title, and if the program is a movie, the name of the distribution software company of the movie and the name of the leading actor are shown, and the correspondence with the ID code is indicated. If the program is paid, the fact is displayed, and the reception fee is settled after being associated with the user ID. As for the current time N, the device has an automatic time setting function, and the accurate time in the area is built in, which is useful for timer reservation and the like.
[0039]
The channel allocation information O indicates the status of allocation of the broadcast program to each channel, the broadcast start date and time information P indicates the broadcast start date and time as the broadcast start information, and broadcast schedule information for about one week from the current time is broadcast. Useful for reservations etc. The broadcast end date / time information Q indicates the broadcast end date / time as broadcast end information. In the case of R, a digital broadcast signal is broadcast by compressing a video or audio signal according to, for example, the MPEG2 standard. However, since the compression ratio changes for each program, the R is broadcast with its format information added.
[0040]
Similarly, the recording operation of the television with memory of the present invention will be described with reference to the flowchart of FIG.
The user operates the remote controller 2 while receiving the television device 1 with a memory to select and start the FIFO operation mode (step SP1). In step SP2, the remaining recordable capacity of the large-capacity memory of the television apparatus with memory 1 itself is checked and stored. In step SP3, information such as a category is detected from the broadcast content transmitted with the ID code from the broadcast station and stored. At step SP4, it is confirmed whether or not the user has made a program reservation. If the user has made a program reservation, the program is preferentially accepted. If there is no program reservation by the user, the broadcast contents are classified by category as they are.
[0041]
In step SP5, if a category area is selected and a broadcast station is specified, the category code is detected and stored. In step SP6, a FIFO operation for sequentially deleting the oldest recorded contents and recording new broadcast contents is performed. In step SP7, the remaining capacity of the memory capacity allocated to the category area is checked, and if the recording capacity of the category area has a margin, the process proceeds to step SP8. If the recording capacity does not have a margin, the process proceeds to step SP6. The return FIFO operation is repeated to update the broadcast contents. In step SP8, the ID code such as the broadcast time is checked, and if they match, the process proceeds to step SP9 to continue the recording, and if they do not match, the process returns to step SP8 again to act to match the broadcast time. In step SP10, a series of recording mode operations ends.
[0042]
Next, the operation at the time of reproduction will be described. When the reproduction mode is selected by the user (step SP11), a menu showing each category area shown as an example in FIG. 3 is displayed in step SP12 based on the control program in the ROM / RAM. At step SP13, at the same time, the reproduction preparation of the large-capacity memory is designated. In step SP14, the menu display is deleted.
[0043]
Moving to step SP15, when the user attempts to select a desired category area by operating, for example, a trackball on the remote control unit 2, a pointer (instruction mark) appears on the display unit 3, and when the trackball is clicked and confirmed. The category area is determined, and the routine goes to the next step SP16. If the category selection is not confirmed, the menu display is continued. In step SP16, the directory information of the determined category area is referred to, and in step SP17, the latest recorded content is immediately displayed on the display unit 3 of the television set 1 with memory. In step SP18, the user can operate the reproduced content, and, for example, the viewer can freely change the reproduction speed by operating the FF button 25 in FIG. Further, when the user selects another category area, the process returns to step SP15 to perform a series of operations.
[0044]
In the above-described embodiment, the automatic recording mode has been mainly described. However, a manual operation of selecting desired program software and recording the desired program software on a desired recording medium as in a normal television device with a built-in recording device is also possible. In this case, desired program software is designated by a remote control unit 2 shown in FIG. 2 by a broadcast content selection switch (not shown), and is selected by the tuner 7. Similarly, a desired recording medium is instructed from the remote controller 2 to the system controller 10 to start a recording operation.
[0045]
Further, in the above-described embodiment, the case where the user directly operates the remote control unit 2 has been described. However, an operation mode is displayed on the display unit 3, and the operation mode can be operated with a trackball or a cross key. 3 can operate only the large capacity memory in the standby state. Further, it goes without saying that the present invention can be developed into various forms without being limited to the above embodiment.
[0046]
【The invention's effect】
As described above, according to the present invention, it is highly likely that a form incorporating various large-capacity memories will be adopted as a television apparatus compatible with new media and multimedia in the future. These large-capacity memories have been improved in function, capacity and quality as they evolved, and may not only be incorporated in the television device from the beginning, but also may be optionally incorporated in the television device. Even with the arrival of such a television device with a memory, the user does not have to pay special attention to the functions and properties of the large-capacity memory owned by the user, and from among a huge number of broadcast programs broadcast even when the user is absent. Since the data is automatically categorized and recorded, a busy viewer can be easily and quickly obtained the latest information without having to deal with the complicated operation as in the case of a VTR.
[0047]
In addition, the television device with memory according to the present invention has a certain amount of user area, so that it can be used as a VTR, and a library to some extent can be formed. In this case, since the system controller performs recording / reproduction in an optimum recording state, recording does not fail. Further, processing after recording in the large-capacity memory is also easy, and the large-capacity memory is easily arranged because it is organized neatly by category or by time.
