Description

Specification

Content receiving apparatus and content conversion program

Technical field

The present invention relates to a content receiving apparatus and a content conversion program, and more specifically to a content receiving apparatus and a content conversion program related to satellite digital broadcast, terrestrial digital broadcast, and the like.

Background art

[0002] In content data distribution such as satellite digital broadcasting and terrestrial digital broadcasting, ISO (International Standards Organization) 13818 technology called MPEG2 (Moving Picture Experts Group phase 2) is employed. In MPEG2, packetized video and audio are packetized and distributed in a fixed-length TS (Transport Stream) format suitable for transmission, that is, MP EG-TS signals.

[0003] Data distributed in the MPEG-TS signal is described using a document description language called BML (Broadcast Markup Language). By using BML, it is possible to control screen display and to define links, titles and body text, and user interfaces (for example, link icons).

[0004] It is assumed that content distributed as data described in BML is received by a home television and displayed on a screen. For this reason, for example, an operation input when the user selects a link is performed by selecting and inputting a desired link icon by a remote control operation.

[0005] By the way, a case is considered in which content is distributed by data described in BML and received by a content receiving device such as car navigation and displayed on the screen. In this case, the driver performs operation input by alternately checking the screen displaying the content and the remote control. However, performing such remote control operations while driving is dangerous for the driver.

[0006] Conventionally, a content receiving apparatus capable of inputting an operation without requiring such a remote control operation with danger has been proposed. This content receiving device displays content. It uses a touch panel that allows operation input by touching the surface of the screen shown. By adopting such a touch panel, the driver can simultaneously check the screen displaying the content and perform an operation input, thereby reducing the danger associated with the operation input (for example, Patent Document 1). ).

Disclosure of the invention

Problems to be solved by the invention

However, in the conventional content receiving apparatus described above, the size of the operation button on the touch panel is not taken into consideration. Since digital broadcasting is assumed to be displayed on a television with a large screen for home use, when displaying on a small screen of a navigation device, the size of the fingertip is larger than the size of the operation button. Therefore, there is a high possibility that an operation button different from the operation button intended by the user will be input.

The present invention has been made in view of such problems. That is, it is an object of the present invention to provide a content receiving apparatus and a content conversion program that improve operational convenience when performing operation input on received content. Means for solving the problem

[0009] An aspect of the present invention is directed to a content receiving apparatus that is connected to a distribution station that distributes content data via a network and receives content data. The present invention provides an input means for accepting an operation input from a user, a receiving means for receiving content data distributed from the distribution station, and an interpretation means for interpreting a description of content data received by the receiving means. Conversion means for converting the description of the content data interpreted by the interpretation means into a description suitable for operation input, and display means for displaying the content corresponding to the content data generated by the conversion by the conversion means It is configured.

[0010] Thereby, it is possible to provide a content receiving apparatus with improved operational convenience when performing an operation input on the received content.

[0011] It should be noted that the conversion means may be configured to convert a description corresponding to the icon among the descriptions of the content data interpreted by the interpretation means.

[0012] Note that the conversion means refers to the description of the size of the icon in the description of the content data. Therefore, a configuration may be adopted in which conversion is performed when the size is equal to or smaller than a predetermined threshold value. It should be noted that the configuration is a vehicle-mounted device.

[0013] The present invention is premised on a content conversion program that is connected to a distribution station that distributes content data via a network and that is executed by a computer of a content receiving device that receives the content data. The present invention interprets the description of the received content data, the input step of accepting the operation input from the user through the input means, the reception step of receiving the content data distributed from the distribution station through the reception means, and the computer. And a display control step for displaying on the display means the content corresponding to the content data generated by the conversion, and a conversion step for converting the description of the interpreted content data into a description suitable for operation input. It is.

[0014] Thereby, it is possible to provide a content conversion program with improved operational convenience when performing an operation input on the received content.

The communication unit 202 is not limited to a mobile phone, and may be an interface connected by a communication method such as PHS, wireless LAN, or DSRC (Dedicated Short Range Communication)! , V, or any combination! /

The DAC 203 is a circuit that converts digital audio data into an analog audio signal based on the control of the control unit 201 in order to output the content data to the speaker 204. In FIG. 2, an amplifier is omitted between the DAC 203 and the speaker 204 in order to simplify the description.

The display monitor 205 displays content corresponding to the content data received by the communication unit 202. The drawing LSI 206 is a circuit that converts the content data into drawing data so that the control unit 201 displays the content corresponding to the content data on the display monitor 205 based on the control.

[0024] The input unit 207 is an operation device such as a touch panel that receives input from the user. The user selects and inputs, for example, an icon using the input unit 207 while viewing the content displayed on the display monitor 205 with the input unit 207.

The storage unit 208 is used for temporarily storing data to perform streaming or for executing a program that controls the entire in-vehicle device 100. Interpretation unit 209 interprets the description of the content data received by communication unit 202. For example, if the content data is described in BML, the interpretation unit 209 interprets the BML description.

The conversion unit 210 converts the description interpreted by the interpretation unit 209 into a description suitable for operation input.

The display monitor 205 and the input unit 207 are configured to be provided inside the in-vehicle device 100. However, it may be provided outside the in-vehicle device 100.

In addition, the distribution station 120 includes a control unit 211, a communication unit 212, and a storage unit 213. The control unit 211 controls processing of the distribution station 120 as a whole. The communication unit 212 communicates with the in-vehicle device 100 via the network 110. The storage unit 213 stores, for example, digital broadcast content data to be distributed, such as an HDD (node disk).

Next, the operation of the in-vehicle device as the content receiving device according to the embodiment of the present invention will be described using the flowchart of FIG.

[0029] When the user turns on the power source of the in-vehicle device 100 (step S301), the content is received by the digital broadcast content data communication unit 202 distributed from the distribution station 120 (step S302). Here, it is assumed that content data described in BML is received, and when the content corresponding to this content data is displayed on the display monitor 205, the text is displayed on the left side as shown in FIG. It is assumed that the icons A to F are displayed on the screen.

[0030] When the content data distributed from the distribution station 120 is received, the interpretation unit 209 of the in-vehicle device 100 interprets the BML description of the content data received by the communication unit 202 (step S303). When the BML description of the content data is interpreted, the conversion unit 210 converts the interpreted BML description into a BML description suitable for operation input (step S304).

[0031] In the conversion process of step S304, as shown in FIG. 5, from the interpreted BML description, <s tyle X! CDATA [# status {left: 25px; top: 50px; width: 100px; height: 2 5px; font- size: 20px; background-color- index: o;}]> Z style> etc. If detected, the detected BML description is <style> as shown in Fig. 6. CDATA [# status {left: 200ρχ; top: 100px; width: 100px; height: ΙΟΟρx; font-size: 30px; background-color-index: 6;} is converted to a BML description of style.

[0032] The above description of left: 200px is a description indicating the horizontal position in the display area when the icon is displayed on the display monitor 205. top: The description of 100px is that the icon is displayed on the display monitor 205. This is a description showing the vertical position in the display area when displayed. The description of width: ΙΟΟρχ is a description indicating the size of the icon in the horizontal direction. The description of height: ΙΟΟρχ is a description indicating the size of the icon in the vertical direction (see FIG. 7). The description of font-size: 30px is a description indicating the font size of the character for identifying the icon.

[0033] This is a BML description capability corresponding to the position of the icon of the content, the size of the icon, and the font size of the character for identifying the icon. The BML description is described with a predetermined parameter value suitable for operation input. Indicates that it will be converted. This predetermined parameter value is a value in which the icon of the content displayed on the display monitor 205 and the operation button of the input unit 207 match in position and size.

[0034] When the content corresponding to the content data generated by this conversion is displayed on the display monitor 205, as shown in FIG. 8, the text is displayed on the left side, and the icons A to A suitable for operation input are displayed on the right side. F are arranged and displayed in a matrix (step S305).

That is, the operation button of the input unit 207 matches the icon of the content displayed on the display monitor 205, so that the user can easily understand the operation input and the user does not make an error in the operation input. As a result, it is possible to improve operational convenience when performing operation input on the received content.

Control unit 201 of in-vehicle device 100 determines whether or not the power is turned off when displayed on content force display monitor 205 generated by conversion unit 210 by conversion (step S306).

) o

[0037] If it is determined in step S306 that the power has been turned off, the processing ends.

On the other hand, if it is determined that the power is not turned off, the process returns to the process of step S302 and received by the digital broadcast content data communication unit 202 distributed from the distribution station 120. Done.

[0038] Note that the conversion unit 210 may be configured to perform conversion when the size is equal to or smaller than a predetermined threshold with reference to the description of the icon size in the BML description interpreted by the interpretation unit 209. For example, the size threshold in the vertical direction may be the length of the standard human first joint, and the size threshold in the horizontal direction may be the width of the standard human finger. That is, the size of the icon corresponds to the size of the finger. Thereby, it is possible to improve the convenience of operation when performing operation input on the received content. In the above embodiment, the case where the operation device (input unit 207) is a touch panel has been described. However, the present invention is not limited to this case. For example, the operation device may be a rotation device that performs an operation by rotating the operation device. In this case, when the content corresponding to the content data generated by the conversion of the conversion unit 210 is displayed on the display monitor 205, the text is displayed on the left side and the operation input on the right side as shown in FIG. Appropriate icons A to F are displayed in a curved shape. That is, the content icon is displayed so as to correspond to the rotation operation direction of the rotation device.

[0040] For example, when it corresponds to the operation direction of the right rotation, it is arranged and displayed in a convex curve shape to the right, and when it corresponds to the operation direction of the left rotation, it is arranged in a convex curve shape to the left. Displayed. In other words, the rotation operation direction of the rotation device matches the arrangement direction of the content icons displayed on the display monitor 205, and the operation input is easily understood by the user. As a result, it is possible to improve the convenience of operation when performing operation input on the received content.

[0041] When the operation device is, for example, a mobile phone, the content icon may be displayed so as to correspond to the numeric keypad of the mobile phone.

[0042] Further, the content data received by the in-vehicle device 100 is not limited to that described in BML but may be described in a markup language such as HTML (Hyper Text Markup Language).

In the present invention, a software program (in the embodiment, a program corresponding to the flowchart shown in the drawing) for realizing the above-described embodiment is supplied to the apparatus, and the computer of the apparatus is supplied. This includes the case where the program is also read and executed. Therefore, in order to implement the functional processing of the present invention with a computer, the program itself installed on the computer also implements the present invention. That is, the present invention also includes a content conversion program for realizing the functional processing of the present invention.

[0044] Note that content data described so as to correspond to a plurality of types of operation devices of the in-vehicle device is prepared in advance on the distribution station 120 side, and the content data to be received is selected on the in-vehicle device side. Also good. In this case, content data corresponding to an operation device such as a touch panel, a rotation device, and a numeric keypad is selected. At this time, the in-vehicle device 1 The content data may be automatically selected based on the operation device ID of 00, or the user may select the content data by selecting and inputting the operation data according to the operation device. .
