The reception device 31 receives a broadcast program broadcast from the transmission device 11, displays a video of the received broadcast program, and reproduces the sound of the broadcast program. The receiving device 31 is installed, for example, in each home or business office. In the example illustrated in FIG. 1, the number of receiving apparatuses 31 is one, but in general there are a plurality of receiving apparatuses 31. The broadcasting system 1 according to the present embodiment further provides text broadcasting. There are two types of teletext: subtitle broadcast and text super. In caption broadcasting, character data is provided to the receiving device 31 in synchronization with audio-video data provided in a certain broadcast program. In subtitle broadcasting, there may be provided text data that represents a written description of the video represented by the video data, or text that has been transcribed into text. On the other hand, in the character superimpose, character data is transmitted asynchronously with the audio / video data. In the following description, character data mainly related to caption broadcasting will be exemplified, but in the present embodiment, it may be applied to character data related to a character supermarket instead.

  The transmission device 11 transmits program data representing the content of the broadcast program to the reception device 31 via the broadcast transmission path 12 using a predetermined transmission method (for example, a transmission method defined by ARIB STD-B44). The program data includes character data, audio data, and video data, which are multiplexed using a predetermined multiplexing method (for example, MMT: MPEG Media Transport). The character data transmitted by the transmission device 11 is character data representing characters in some languages among a plurality of languages provided in the broadcast program. Some languages are, for example, Japanese and English. Character data representing characters of some languages. One of the languages, for example, Japanese, is the same language as the language related to audio data and the language related to video data. In the following description, audio data and video data are generically referred to as audio video data, and character data representing characters in some languages are generically referred to as partial language character data. Note that, in a broadcast program that does not provide text broadcasting, the transmission device 11 does not transmit partial language character data.

  The broadcast transmission path 12 is a transmission path for transmitting various data transmitted by the transmission apparatus 11 to an unspecified number of reception apparatuses 31 in one direction at the same time. The broadcast transmission path 12 is a radio wave (broadcast wave) in a predetermined frequency band relayed by the broadcast satellite 13. A part of the broadcast transmission path 12 may include a communication line, for example, a communication line from the transmission device 11 to a transmission facility for transmitting radio waves.

  The server device 21 multiplexes the multilingual character data with a predetermined multiplexing method via the communication transmission path 22 and transmits the multilingual character data to the receiving device 31 using the predetermined transmission method. Multilingual character data is character data representing characters in the remaining languages among a plurality of languages provided in a broadcast program. The remaining languages are, for example, French, Spanish, Chinese, Korean, etc. Note that the server device 21 does not transmit multilingual character data in a broadcast program in which character broadcast is not provided. The location of the server device 21 is notified to the receiving device 31 via the broadcast transmission path 12 as an IP (Internet Protocol) address as part of configuration information (described later).

  The communication transmission path 22 is a transmission path for bidirectionally transmitting various data between the server device 21 and the receiving device 31. The communication transmission path 22 includes, for example, a wide area communication network such as the Internet. The communication transmission path 22 may be a communication network including a wireless access network in part, for example, a public wireless communication network. Note that transmission (or transmission, reception) of various data via the communication transmission path 22 may be referred to as “transmission (or transmission, reception) via communication”.

  The receiving device 31 receives audio / video data and partial language character data via the broadcast transmission path 12 and receives multilingual character data via the communication transmission path 22. The receiving device 31 determines the language of the received various character data, and when there are a plurality of languages of the character data to be transmitted, the display of the set language set in the language setting is displayed rather than the display of other languages. Display the priority guidance screen. The receiving device 31 selects one of a plurality of languages represented by the guidance screen based on the operation input, and displays the characters indicated by the character data of the selected language as the content of the text broadcast. The receiving device 31 is an electronic device having a function capable of receiving a television broadcast, such as a television receiving device or a video recording device.

The audio / video data acquisition unit 111 acquires audio data encoded by a predetermined audio encoding method. The audio encoding method is, for example, an audio encoding method defined by ISO / IEC 14496 Part 3 (also referred to as MPEG-4 audio). The audio / video data acquisition unit 111 outputs the acquired video data and audio data to the multiplexing unit 114.

  The character data acquisition unit 112 acquires character data indicating characters broadcast as subtitles. The character data acquisition unit 112 acquires, as partial language character data, character data for each language indicating characters of a part of languages among characters of a plurality of languages constituting the program. The character data acquisition unit 112 outputs the partial language character data to the multiplexing unit 114 as a separate stream for each language.

  The configuration information acquisition unit 113 acquires configuration information that is information for configuring a broadcast program and a service provided along with the broadcast. The configuration information includes a list of assets that are components of broadcast programs and services, and information indicating their requirements. An asset is element data that is a component of a program. The element data is, for example, audio data, video data, character data, etc. of individual streams. The configuration information includes information on partial language character data and multilingual character data as information on character data of a plurality of languages constituting the program. That is, the configuration information acquisition unit 113 provided by broadcasting outputs the acquired configuration information to the multiplexing unit 114.

The transmission unit 116 transmits the multiplexed data input from the encryption unit 115 to the reception device 31 via the broadcast transmission path 12. Here, the transmitting unit 116 modulates a carrier wave having a predetermined carrier frequency by using multiplexed data that is a baseband signal, and transmits a radio wave (broadcast wave) in a channel band corresponding to the carrier frequency by an antenna (not shown). Radiate.

(MPT data structure)
Next, an example of MPT included in the configuration information will be described.
FIG. 3 is a diagram illustrating an example of MPT. The MPT includes an asset type (asset_type), location information (MMT_general_location_info ()), and an asset descriptor area (asset_descriptors_byte) for each asset. In the asset type (asset_type), a code indicating the type of asset is described. As the asset type (asset_type), for example, one of hcv1 indicating video data encoded by HEVC, mp4a indicating audio data encoded by MPEG-4 audio, and stpp indicating timed text is described. . Timed text refers to character data provided by subtitles or character superimposition. The asset descriptor area (asset_descriptors_byte) is an area in which a descriptor for each asset is described. As the descriptor for each asset, for example, an MH-data encoding scheme descriptor (MH-Data_Compound_Descriptor ()) [described later] related to character data is described.

Next, location information (MMT_general_location_info ()) described in MPT will be described.
FIG. 4 is a diagram illustrating an example of a data structure of location information.
The location information (MMT_general_location_info ()) includes a location type (location_type). The location type (location_type) indicates a data flow, that is, a type of a transmission path used for transmission. For example, any value such as “0x00” or “0x02” is described as the location type (location_type).
“0x00” indicates an IP data flow in which MPT including the location information (MMT_general_location_info ()) is transmitted, that is, the broadcast transmission path 12. “0x02” indicates an IPv6 data flow, that is, a communication transmission path 22 having the server device 21 specified by the IPv6 format IP address as the transmission source or destination. When “0x00” is described as the location type (location_type), the packet ID (packet_id) of the transmitted packet is specified in the location information (MMT_general_location_info ()). When “0x02” is described as the location type (location_type), in the location information (MMT_general_location_info ()), the source IPv6 address (ipv6_src_addr), the destination IPv6 address (ipv6_dst_addr), the destination port number (dst_port) An ID (packet_id) is specified.

FIG. 5 is a diagram illustrating an example of the MH-data encoding scheme descriptor.
The MH-data encoding scheme descriptor (MH-Data_Compound_Descriptor) includes additional identification information (additional_data_component_info). In the additional identification information (additional_data_component_info), additional identification information (Additional_Arib_Subtitle_Info ()) having the data configuration shown in FIG. 6 is described.

  The additional identification information (Additional_Arib_Subtitle_Info ()) includes a language code (ISO_639_language_code) and a caption type (type). As the language code (ISO_639_language_code), a language code indicating the language of the character indicated by the character data related to the asset is described in three alphabetic characters. For example, the language code “jpn” indicates Japanese, and the language code “eng” indicates English. As the subtitle type (type), a value indicating the type of broadcast service provided by the character data is described. For example, the caption type “00” indicates caption broadcasting, and the caption type “01” indicates character superimposition.

FIG. 7 is a diagram illustrating an example of setting the language of character data to be transmitted.
In this setting example, it is assumed that character data related to caption broadcasting in four languages is transmitted in one program. Character data in each language is treated as an independent asset. Each asset is identified using an asset ID (asset_id_byte).
For any asset, “stpp” indicating character data is specified as the asset type (asset_type), and “00” indicating subtitle broadcasting is specified as the caption type (type).

  The designation of the language code “eng” and the location type “0x00” relating to the asset ID “0x10” indicates that English character data is transmitted through the broadcast transmission path 12. The designation of the language code “fra” and the location type “0x02” related to the asset ID “0x11” indicates that French character data is transmitted through the communication transmission path 22. The designation of the language code “zho” and the location type “0x02” relating to the asset ID “0x12” indicates that Chinese character data is transmitted through the communication transmission path 22. The designation of the language code “jpn” and the location type “0x00” relating to the asset ID “0x13” indicates that Japanese character data is transmitted through the broadcast transmission path 12. Therefore, these settings indicate that English, French, Chinese, and Japanese text broadcasts are provided in the broadcast program. Character data indicating the contents of English and Japanese character broadcasts are transmitted as partial language character data from the transmission device 11 via the broadcast transmission path 12. Character data indicating the contents of character broadcasts in French and Chinese is transmitted from the server device 21 via the communication transmission path 22 as multilingual character data.

The receiving unit 311 is, for example, a tuner. The receiving unit 311 outputs the received signal of the broadcast channel band received as a broadcast wave to the decoding unit 312.

  The decryption unit 312 demodulates the reception signal input from the reception unit 311 into multiplexed data (encrypted) that is a baseband signal. The decryption unit 312 decrypts the demodulated multiplexed data and the decryption method (for example, AES) corresponding to the method used by the encryption unit 115 of the transmission device 11 to generate the decrypted multiplexed data. The decoding unit 312 outputs the generated multiplexed data to the separation unit 313.

  The separation unit 313 separates the multiplexed data input from the decoding unit 312 into video data, audio data, partial character data, and configuration information. The separation unit 313 outputs partial character data and configuration information to the control unit 331. Further, the separation unit 313 outputs audio data to the audio decoding unit 314 and outputs video data to the video decoding unit 317.

The audio decoding unit 314 decodes the audio data input from the separation unit 313 by a decoding method corresponding to the encoding method (for example, MPEG-4 audio) used for encoding, and generates original audio data. . The voice decoding unit 314 outputs the decoded voice data to the loudspeaker 316.
The loudspeaker 316 reproduces the voice indicated by the voice data input from the voice decoder 314. The loudspeaker 316 includes, for example, a speaker.

  The video decoding unit 317 decodes the video data input from the separation unit 313 by a decoding method corresponding to the encoding method (for example, HEVC) used for encoding, and generates original video data. The decoded video data is data indicating signal values forming a video (frame image) at each time. The video decoding unit 317 outputs the decoded video data to the display synthesis unit 318.

The display synthesis unit 318 synthesizes the video data input from the video decoding unit 317 and the various screen data input from the control unit 331 to generate video data indicating a video for display. The screen data includes, for example, device setting screen data for setting functions of the receiving device 31, channel selection screen data for selecting a broadcast channel, and the like.
The display unit 319 reproduces a video based on the video data input from the display synthesis unit 318. Accordingly, various screens are displayed on the display unit 319 so as to be superimposed on the video related to the received video data. The display unit 319 includes a display, for example.

  The storage unit 322 stores various data. The storage unit 322 includes a storage medium, for example, an HDD (Hard-disk Drive), a flash memory, a ROM (Read-only Memory), a RAM (Random Access Memory), or a combination thereof. Examples of data stored in the storage unit 322 include device setting screen data, device setting data, guidance display templates, character conversion tables, font data, and the like. The device setting screen data is data representing the device setting screen. The device setting data is data indicating the set device setting. The device setting includes a setting language indicating the set language. The guidance display template is data for generating guidance display data for selecting a language of character data. The character conversion table is data used for decoding a character code included in character data for each language. Font data is data indicating the size and font of characters for each language.

  The operation input unit 323 acquires an operation signal generated by receiving an operation input by a user, and outputs the acquired operation signal to the control unit 331. The operation signal includes, for example, a signal indicating power on / off, a signal indicating a broadcast wave reception channel, a signal indicating the language of the guidance display, a signal indicating the content of the setting item on the device setting screen, and the like. . The operation input unit 323 is, for example, an input interface that receives an operation signal from an electronic device such as an operation button, a remote controller, or a mobile terminal device.

The control unit 331 controls various operations of the receiving device 31. For example, the control unit 331 determines the language of character data in one program from the configuration information input from the separation unit 313. When there are a plurality of determined languages, the display composition unit displays screen data indicating notification information that preferentially represents the same language as the set language set in the language setting related to the function of the receiving device 31 over other languages Output to 318. The notification information displayed on the display unit 319 includes a list of determined languages, and displays the same language as the set language with priority over other languages. Based on the input signal from the operation input unit 323, the control unit 331 selects one of a plurality of languages represented by the notification information, indicates image data representing characters represented by the character data of the selected language, and displays the characters. The data is displayed on the display unit 319.
The communication unit 341 transmits and receives various data to and from the server device 21 via the communication transmission path 22. The communication unit 341 is, for example, a communication interface.

(Configuration of control unit)
Next, the configuration of the control unit 331 according to the present embodiment will be described.
FIG. 9 is a block diagram illustrating a configuration of the control unit 331 according to the present embodiment.
The control unit 331 includes a device setting unit 332, a channel selection unit 333, a language determination unit 334, a language selection unit 335, a character data acquisition unit 336, and a display control unit 337.

  The device setting unit 332 determines device settings related to the function of the receiving device, and stores device setting data indicating the determined device settings in the storage unit 322. The item of device setting includes language setting. The language setting is an item for the reception device 31 to set a language used for displaying a message related to the function of the own device. The message includes a message for guiding the function of the own device and the operation of the own device. A message for notifying the state is included. The language set by the language setting is the setting language. The device setting unit 332 reads device screen setting data stored in advance from the storage unit 322, and outputs the read device setting screen data to the display composition unit 318. Thereby, the device setting unit 332 displays a device setting screen. The device setting unit 332 specifies the language indicated by the input signal from the operation input unit 323 among a plurality of languages that can be set in the language setting.

  The device setting unit 332 generates device setting data including the specified language as the setting language, and stores the generated device setting data in the storage unit 322. The timing at which the device setting unit 332 displays the device setting screen is, for example, when the receiving apparatus 31 is activated for the first time, or when an input signal instructing device setting is input from the operation input unit 323. Note that device setting data including a default setting language may be stored in the storage unit 322 in advance.

  The channel selection unit 333 selects a broadcast channel designated by the input signal input from the operation input unit 323, and outputs a broadcast channel signal indicating the selected broadcast channel to the reception unit 311. Thereby, the channel selection unit 333 can cause the reception unit 311 to receive a broadcast wave in a channel band corresponding to the selected broadcast channel. The storage unit 322 stores channel selection screen data for selecting a broadcast channel in advance. The channel selection unit 333 may display the channel selection screen on the display unit 319 by reading the channel selection screen data and outputting the read channel selection screen data to the display synthesis unit 318.

  The language determination unit 334 detects the MPT from the configuration information input from the separation unit 313, and determines the language for each character data related to one broadcast program based on the detected MPT. The determined language is called a broadcast language. Here, the language determination unit 334 refers to the asset type (asset_type), location information (MMT_general_location_info ()), and asset descriptor area (asset_descriptors_byte) for each asset. The language determination unit 334 determines an asset whose value described in the asset type (asset_type) is “stp” as an asset related to character data. The language determination unit 334 determines the language indicated by the language code (ISO_639_language_code) included in the additional identification information (Additional_Arib_Subtitle_Info ()) described in the asset descriptor area (asset_descriptors_byte) as the broadcast language of the asset.

Note that the language determination unit 334 determines that an asset whose value described in the location information (MMT_general_location_info ()) is “0x00” is an asset transmitted through the broadcast transmission path 12, and an asset whose value is “0x02”. Are determined to be assets transmitted through the communication transmission path 22. When the value is “0x02”, the language determination unit 334 specifies the IP address of the server device 21 as the transmission source address described in the location information (MMT_general_location_info ()).
The language determination unit 334 outputs to the language selection unit 335 data indicating the broadcast language and transmission path of the character data determined for each asset.

  The language selection unit 335 determines whether there are a plurality of broadcast languages indicated by data input from the language determination unit 334 or one or less. If there is one, the one broadcast language is selected as the display language. If there are a plurality of languages, the language selection unit 335 performs the processing described below. The language selection unit 335 reads the guidance display template from the storage unit 322. The language selection unit 335 refers to the device setting data and determines whether or not the same language as the set language is included in the broadcast language. In the case where the same language as the set language is included, the display order of the same language is determined to be prioritized over the display of other broadcast languages. The display order of other broadcast languages is determined in an arbitrary order, for example, in ascending order of asset IDs. When the broadcast language does not include the same language as the set language, the order of all broadcast languages is determined in an arbitrary order, for example, the ascending order of asset IDs.

The language selection unit 335 generates guidance display data by arranging the broadcast language display for each asset in the guidance display template in a predetermined order. Here, the language selection unit 335 decodes the character code of the character representing the broadcast language of each asset with reference to the character conversion table of the set language, and broadcasts in the size and font specified by the predetermined font data. Generate a language display. The language selection unit 335 causes the display unit 319 to display the guidance display as the notification information in the set language by outputting the generated guidance display data to the display synthesis unit 318. The timing at which the language selection unit 335 displays the guidance display is, for example, within a predetermined period (for example, 15 seconds) from any one of the following times (1) to (3). (1) When the display of a text screen provided by multilingual character broadcasting is started after the receiving device 31 is turned on, (2) the broadcasting time of the broadcasting program ends and the next multilingual character broadcasting broadcast program (3) When a broadcast program of multilingual teletext received by changing the receiving channel is changed.
The language selection unit 335 selects the broadcast language indicated by the input signal input from the operation input unit 323 as the display language. The language selection unit 335 outputs data indicating the selected display language and the transmission path of the asset related to the display language to the character data acquisition unit 336.

  The character data acquisition unit 336 acquires the character data of the asset relating to the display language indicated by the data input from the language selection unit 335 from the received signal received through the transmission path indicated by the data. When the broadcast transmission path 12 is designated as the transmission path, the character data acquisition unit 336 extracts the asset character data from the partial language character data input from the separation unit 313. When the communication transmission path 22 is designated as the transmission path, the character data acquisition unit 336 extracts the asset character data from the multilingual character data input from the communication unit 341. The character data acquisition unit 336 outputs the acquired character data and display language data indicating the display language to the display control unit 337.

  The display control unit 337 displays the text screen data indicating the text screen in which the character indicated by the character data input from the character data acquisition unit 336 is arranged in the display area indicated by the layout information included in the component input from the separation unit 313. Is generated. Here, the display control unit 337 decodes the individual character codes constituting the character data using the character conversion data stored in the storage unit 322, and the size and font indicated by the font data specified in the character data. A text screen containing the characters The display control unit 337 outputs the generated text screen data to the display composition unit 318, thereby causing the display unit 319 to display the text screen superimposed on the video.

Next, the reception process according to the present embodiment will be described.
FIG. 12 is a flowchart showing a reception process according to the present embodiment.
(Step S <b> 101) The receiving unit 311 receives a broadcast wave transmitted from the transmission device 11. The decrypting unit 312 demodulates the received broadcast wave and converts it into encrypted multiplexed data, and decrypts the converted multiplexed data. The separation unit 313 separates the multiplexed data into video data, audio data, partial language character data, and configuration information. Thereafter, the process proceeds to step S102.
(Step S102) The language determination unit 334 detects MPT from the configuration information input from the separation unit 313, and determines the broadcast language for each character data related to one broadcast program based on the detected MPT. Thereafter, the process proceeds to step S103.

(Step S103) The language selection unit 335 determines whether there are a plurality of broadcast languages. When it is determined that there are a plurality (YES in step S103), the process proceeds to step S104. When it is determined that the number is one (NO in step S103), the language selection unit 335 determines that one broadcast language as the display language, and then proceeds to step S107.
(Step S104) The language selection unit 335 identifies the setting language with reference to the device setting data. Thereafter, the process proceeds to step S105.
(Step S105) The language selection unit 335 configures a guidance display in which broadcast language displays are arranged in a priority order over other broadcast languages by setting the same broadcast language as the set language at the top. The language selection unit 335 causes the display unit 319 to display the configured guidance display as notification information. Thereafter, the process proceeds to step S106.

(Step S106) The language selection unit 335 selects the broadcast language indicated by the input signal input from the operation input unit 323 as the display language. Thereafter, the process proceeds to step S107. Thereafter, the process proceeds to step S107.
(Step S107) The display control unit 337 causes the display unit 319 to display a text screen in which characters indicated by the character data of the selected display language are arranged in a predetermined display area in the display language. Then, the process shown in FIG.

As described above, the receiving device 31 according to this embodiment includes the language determination unit 334 that determines the language of character data in each program. When the number of languages of the character data is plural, the notification information indicating the same language as the set language set in the device setting related to the function of the own device is given priority over other languages, and the plural represented by the notification information A language selection unit 335 for selecting one of the languages. In addition, the receiving device 31 includes a display control unit 337 that displays characters indicated by the character data in the language selected by the language selection unit 335.
With this configuration, the setting language is preferentially represented in the notification information among the languages provided in the teletext provided in a plurality of languages, so that selection of the setting language is prompted. Therefore, even when there are many languages provided in a program, or even when the provided languages differ from program to program, it is easy to select a language by setting a user-desired language as a setting language in advance.

In the notification information output from the language selection unit 335, a plurality of languages are displayed using the set language.
With this configuration, a language desired by the user or a language that can be understood is set in advance as a setting language, thereby facilitating selection of a language provided by text broadcasting.

In addition, the reception device 31 acquires character data of some languages transmitted by broadcast from the reception signal received by the reception unit 311 via broadcast, and acquires character data of other languages received by the communication unit 341 via communication. A character data acquisition unit 336 is provided.

Next, a second embodiment of the present invention will be described. About the same structure as embodiment mentioned above, the same code | symbol is attached | subjected and the description is used.
In the receiving device 31 (FIG. 8) according to the present embodiment, the language selection unit 335 (FIG. 9) includes a language (non-displayable language) that cannot display the characters indicated by the character data among the broadcast languages of each asset. It is determined whether or not. For example, the language selection unit 335 stores in the storage unit 322 (FIG. 8) one or both of a character conversion table for decoding characters in the broadcast language and font data relating to the character size and font of the broadcast language. If not, the broadcast language is determined as a non-displayable language. In other words, the language selection unit 335 (FIG. 9) selects a language that satisfies one or both of the fact that the receiving device 31 cannot decode and the font does not support as a non-displayable language. The language selection unit 335 configures the guidance display represented by the visibility lower than the broadcast language determined to be able to display the display of the broadcast language determined to be an undisplayable language in the above-described guidance display. However, the language selection unit 335 may or may not completely erase the display of the non-displayable language.

Next, an example of guidance display according to the present embodiment will be described.
FIG. 13 is a diagram showing an example of guidance display according to the present embodiment.

(Third embodiment)
Next, a third embodiment of the present invention will be described. About the same structure as embodiment mentioned above, the same code | symbol is attached | subjected and the description is used.
In the receiving apparatus 31 (FIG. 8) according to the present embodiment, it is determined whether or not the communication unit 341 (FIG. 8) is connected to the communication transmission path 22 (FIG. 1). For example, when the communication transmission line 22 is wired, the communication unit 341 determines that it is connected when the voltage of the reception signal input from the communication transmission line 22 is within a predetermined range, and the voltage is When it is outside the predetermined range, it is determined that it is not connected. Further, when the communication transmission path 22 is wireless, the communication unit 341 determines that the communication unit 341 is connected when the electric field strength within a predetermined radio frequency band of the received signal is higher than a predetermined electric field strength threshold. When the electric field strength is less than or equal to a predetermined electric field strength threshold, it is determined that the connection is not established. The communication unit 341 outputs a connection impossible signal indicating that the communication unit 341 is not connected to the communication transmission path 22 to the language selection unit 335 (FIG. 9).

  The language selection unit 335 performs the processing described below when a connection impossible signal is input from the communication unit 341. The language selection unit 335 displays the broadcast language of the character data transmitted by communication (corresponding to the above-mentioned “other language”) among the broadcast languages, and displays the broadcast language of the character data transmitted by broadcast (the above-mentioned “one” The guidance display represented by a lower visibility than the "part language". The language selection unit 335 may or may not completely delete the display of “other languages”. Based on the transmission path for each asset indicated by the data input from the language determination unit 334 (FIG. 9), the language selection unit 335 has the language of the character data for each asset belonging to “other languages” or “one”. It can be determined whether it belongs to the “part language”. Further, the language selection unit 335 reads the message data stored in the storage unit 322 in advance, and outputs the read message data to the display synthesis unit 318. The message data is data indicating a guidance message for prompting the user to connect the receiving device 31 to the communication transmission path 22. The display composition unit 318 generates display data in which the guidance display indicated by the guidance display data and the guidance message indicated by the message data are superimposed on the video at different positions. The display composition unit 318 (FIG. 8) outputs the generated display data to the display unit 319 (FIG. 8), thereby causing the display unit 319 to display a guidance display and a guidance message.

Next, examples of guidance display and guidance message display according to the present embodiment will be described.
FIG. 15 is a diagram showing a display example of guidance display and guidance message according to the present embodiment.

The display languages represented by the guidance display GD31 shown in FIG. 15 are Japanese, English, Chinese, and French, and are the same as the languages shown by the guidance displays GD11 (FIG. 10), GD12 (FIG. 11), and GD21 (FIG. 13). However, the display order of these display languages and the language used for display are different. In the guidance display GD31, since the set language is Japanese, the display of “Japanese” is given priority over the display of other display languages, and all are expressed using Japanese. In the guidance display GD31, gray shades are superimposed on display areas of “Chinese” and “French”, which are broadcast languages in which character data is transmitted by communication, so that the character data is transmitted in the broadcast language. Some "Japanese" and "English" displays are not shaded. Accordingly, the visibility of the display of “Chinese” and “French” indicating Chinese and French is displayed lower than the display of each other broadcast language.
In the example shown in FIG. 15, as the guidance message MS31, “please connect to the network to display other subtitles” is communicated to the user in order to display the teletext related to Chinese and French. A message for prompting connection to the transmission path 22 is displayed.

When it is determined that they are connected (YES in step S121), the process proceeds to step S105. When it is determined that the connection is not established (NO in step S121), the process proceeds to step S122.
(Step S122) The language selection unit 335 lowers the visibility of the broadcast language of character data transmitted by communication than the display of the broadcast language of character data transmitted by broadcast. And the language selection part 335 comprises the guidance display which arranged the display of the broadcast language in preference to another broadcast language by making the display of the same broadcast language as a setting language first. The language selection unit 335 causes the display unit 319 to display the configured guidance display as notification information. Thereafter, the process proceeds to step S123.
(Step S123) The language selection unit 335 reads message data stored in the storage unit 322 in advance, and outputs the read message data to the display synthesis unit 318. As a result, the language selection unit 335 causes the display unit 319 to display a guidance message for prompting connection to the communication transmission path 22 (network). Thereafter, the process proceeds to step S106.

As described above, in the notification information output from the language selection unit 335 according to the present embodiment, when the communication unit 341 is not connected to the communication transmission path 22, the display of another language is displayed for some languages. The visibility is lower than the display.
With this configuration, the user can intuitively recognize whether or not a desired language among all provided languages is a language that cannot be received through communication. Therefore, the user is prompted to determine whether or not to select another language that can be received, whether or not to stop viewing, and confirmation of the connection state to the communication transmission path 22.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described. About the same structure as embodiment mentioned above, the same code | symbol is attached | subjected and the description is used. Hereinafter, differences from the first embodiment will be mainly described.

  In the above-described embodiment, an example was given in which the server device 21 (FIG. 1) transmits multilingual character data in one direction. In this embodiment, the case where the broadcast system 1 is a broadcast communication cooperation system is taken as an example. In the present embodiment, when receiving a request signal from the receiving device 31, the server device 21 transmits an application program (hereinafter referred to as an application) to the receiving device 31 as a response. This application is described in a predetermined description language (for example, HTML5), and includes multilingual character data for each language. In addition, in this application, a language setting (for example, a lang attribute) indicating the language of multilingual character data is described. In addition, the application describes an instruction for displaying a text screen in which characters indicated by the character data of the language selected as the display language among the languages of the multilingual character data are arranged in a predetermined display area in the display language. ing.

  In the transmission device 11 (FIG. 2) according to the present embodiment, the configuration information acquisition unit 113 further acquires control information. The control information includes URL (Uniform Resource Locator) of the server device 21 and information for controlling the execution, such as starting and stopping of the application, as application acquisition destination information. The control information is acquired as data having a predetermined format, for example, an MH-Application Information Table (MH-AIT: Application Information Table). The multiplexing unit 114 further multiplexes the control information acquired by the configuration information acquisition unit 113 to generate multiplexed data.

In the receiving apparatus 31 (FIG. 8) according to the present embodiment, the separation unit 313 (FIG. 8) further separates control information from the multiplexed data, and obtains the separated control information from the control unit 331 (FIG. 8). It outputs to the part 336 (FIG. 9).

To do. In the present embodiment, since the character data acquisition unit 336 receives an application instead of the multilingual character data, the character data acquisition unit 336 extracts display language character data from the multilingual character data input from the communication unit 341 (FIG. 8). Do not perform the process.

  The language determination unit 334 determines the language indicated by the language setting described in the application input from the character data acquisition unit 336 as the broadcast language. In this embodiment, the character data of each language included in the application is handled as each asset in the above-described embodiment. Therefore, the language determination unit 334 assigns an asset ID for identifying character data of each language included in the application, and determines that the transmission path for each asset is the communication transmission path 22. When the transmission path related to the display language selected by the input signal is the broadcast transmission path 12, the language determination unit 334 outputs the display language and data indicating the transmission path to the language selection unit 335. In the present embodiment, the MPT does not include information related to assets transmitted through the communication transmission path 22.

  When the data indicating the application and the display language is input from the character data acquisition unit 336 to the display control unit 337, that is, when the broadcast language of the character data included in the application is selected as the display language, the separation unit Control information is acquired from 313. When the control information indicates activation of the application, the display control unit 337 starts processing indicated by the instruction described in the application. In the following description, performing the process indicated by the instruction described in the application is referred to as “executing the application”.
