[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS [First Embodiment: FIGS. 1 to 4]
As a first embodiment, a case is described in which the present invention is applied to a broadcast receiving device that receives digital television broadcasts.

[0014] The broadcast in this case is a broadcast in which the content includes video information and audio information of a program, and additional information is multiplexed on the content.

In the present embodiment, the additional information is added to a part of the program scene, and includes a related position such as a position where the scene is recorded or a position where the facility or store introduced in the scene exists. It includes map information in addition to information (information indicating a position related to content).

The related position information specifically indicates a related position by latitude and longitude. The map information is transmitted before the program or at an appropriate time during the program, and when a place name or an address is changed, a new version of the map information is transmitted.

Specifically, the video data and the audio data are stored in an MPEG (Moving Picture Exp).
In addition, the data is compression-encoded and multiplexed by an erts group (Arts Group) method and the like, and the additional information data is encoded and multiplexed separately from the audiovisual data stream, and the whole is modulated and broadcast.

The additional information data includes a header portion having an identification code indicating the type of the additional information such as whether the additional information is related position information or map information, and a data portion of the related position information or map information following the header portion. It is assumed to consist of

The broadcast signal is multiplexed with decode time information such as a decode time stamp and content presentation time information such as a presentation time stamp.

(First Example of Broadcast Receiving Apparatus: FIG. 1) FIG.
Shows a first example of the broadcast receiving device of the first embodiment.

<Basic Configuration of Broadcast Receiving Apparatus> In the tuning receiving section 19, a broadcasting signal is tuned and received by the system controller 17 based on the tuning operation of the operation section 16 by the viewer. The selected signal is demodulated by the demodulation / error correction unit 21, error-corrected, written to the buffer 22, and read from the buffer 22.

The signal read from the buffer 22 is supplied to a demultiplexer 23,
From the encoded video data, audio data,
Caption data and additional information data are obtained separately.

The video data, the audio data and the subtitle data are stored in a video code buffer 31, an audio code buffer 41 and a subtitle code buffer 51, respectively.
After being read from the video code buffer 31, the audio code buffer 41 and the subtitle code buffer 51, they are decoded by the video decoder 32, the audio decoder 42 and the subtitle decoder 52, respectively.

The system controller 17 controls the decode timing in each of the decoders 32, 42 and 52 based on the timing information such as the above-mentioned decode time stamp, and based on the above-mentioned timing information such as the presentation time stamp. Thus, the output timing of each of the decoders 32, 42, and 52 is controlled so that the time series of the data from each of the decoders 32, 42, and 52 is matched.

The video data from the video decoder 32 and the subtitle data from the subtitle decoder 52 are processed by the video processing unit 33, and the video processing unit 33 superimposes the subtitle signal in the video signal.

A video signal output from the video processing unit 33 is led to a video output terminal 34, and is sent from the video output terminal 34 to a video display device 35 such as a CRT display or a liquid crystal video projector.

The video signal is sent to a video display device 35 having a digital-to-analog (D / A) conversion unit without being converted to an analog video signal by the video processing unit 33, or as digital video data. The signal is converted into an analog video signal by the unit 33 and transmitted to the video display device 35.

The audio data from the audio decoder 42 is processed by an audio processing unit 43, and an audio signal output from the audio processing unit 43 is output to an audio output terminal 44. The sound is output to the sound output device 45.

The audio signal is also sent to an audio output device 45 having a D / A conversion unit as digital audio data without being converted to an analog audio signal by the audio processing unit 43, or the audio processing unit 43 outputs the analog audio signal. The signal is converted into a signal and sent to the sound output device 45.

<Detection of Related Position Information and Presentation of Related Position>
The additional information data separated by the demultiplexer 23 is
After being written into the additional information code buffer 61 and read out from the additional information code buffer 61, it is sent to the map information detecting section 72 and the related position information detecting section 62.

The map information detecting section 72 detects map information from the identification code of the header section in the additional information data.
The detected map information is stored in the map information storage unit 73. In this example, the map information storage device 73
Flash memory or EEPROM built in the receiver
(Electrically-Erasable an
d Programmable ROM).

The related position information detecting section 62 detects related position information such as recording position information from the identification code of the header part in the additional information data.

When the related position information is detected by the related position information detecting section 62, the system controller 17 informs that fact, that is, that the related position information is multiplexed in the scene. The video processing unit 33 is controlled so as to be presented on the display screen of the video display device 35 by the image.

For example, when the recording position information is multiplexed, as shown in FIG. 7A, on the display screen 36 of the video display device 35, the mark 4
Is superimposed.

When the viewer watches the video 3 and wants to know the relevant position such as the recording position, the viewer instructs the reproduction of the relevant position information by operating the operation unit 16.

Thus, the system controller 17
Decodes the related position information detected by the related position information detecting unit 62 and sends the decoded position information to the map image generating unit 64, and stores the related position information in the range including the related position stored in the map information storage unit 73. The map information is read out from the map information storage unit 73 and decoded, and the
To send to.

The map image generating section 64 generates, from the decoded related position information and the map information, map image data in which the position indicated by the related position information is displayed on the map image based on the map information, and generates a video. It is sent to the processing unit 33. Thereby, the relevant position such as the recording position is displayed on the display screen of the video display device 35.

For example, when the recording position information is multiplexed as described above, the recording position is displayed as a mark 6 on the map image 5 on a part of the display screen 36 as shown in FIG. The displayed map image 7 is displayed.

The receiving device is configured so that the positions and sizes of the map images 5 and 7 on the display screen 36 can be changed by an adjustment operation on the operation unit 16.

As for the scales of the map images 5 and 7, the receiving device is configured so that either the automatic scale mode or the manual scale mode can be selected by the setting operation on the operation unit 16. In the automatic scale mode, the scale is switched from the small scale to the large scale at predetermined time intervals, for example, 10 seconds. In the manual scale mode, the direction is changed to the large scale or the small scale by operating the up / down button. If the scale of map images 5 and 7 can be changed,
The map information read from the map information storage unit 73 is changed according to the scale.

When the viewer wants to record the displayed related position, the viewer instructs to save the related position information by operating the operation unit 16.

Thus, the system controller 17
Records and saves the relevant position information at that time in the relevant position information storage unit 63. The associated position information storage unit 63 also
In this example, it is a nonvolatile memory such as a flash memory or an EEPROM built in the receiving device. However, the related position information storage unit 63 and the map information storage unit 73
May be one in which one memory is divided into regions.

By storing the related position information in this way, after viewing the program, the related position information can be reproduced, and the location followed by the traveler in the travel program can be traced and confirmed on a map. be able to.

Further, in this example, a new version of the map information is also added with an update control signal for prompting an update including the version information, multiplexed with the content, and distributed by broadcasting.

The update control signal is supplied to the demultiplexer 2
3 and is detected by the map information detecting section 72. The system controller 17 determines from the version information in the detected update control signal whether or not the received map information is a newer version than the map information stored in the map information storage unit 73. If it is a new version of the map information, the received map information is stored in the map information storage unit 73 instead of the map information stored in the map information storage unit 73, and the map information is updated.

In FIG. 1, the related position information detecting section 6
2. Although the map information detection unit 72, the map image generation unit 64, and the system controller 17 are functionally separated, the functions of the related position information detection unit 62, the map information detection unit 72, and the map image generation unit 64 May be configured as a part of the function of the system controller 17.

<Other Specific Examples> As shown in FIG. 7B, instead of the related position being displayed as the mark 6 on the map image 5, "the photographing location is 35 ゜ 24 'north latitude, 138 経 east longitude. 5
6 '"" Location is 35 10' north latitude, 140 2 east longitude
For example, the latitude and longitude of the related position may be directly displayed as characters (numeric characters), such as “5 ′”.

Further, by operating the operation unit 16, as the display format of the related position, one of the map display format as shown in FIG. 7B and the above-mentioned latitude and longitude direct display format can be selected. The configuration may be as follows.

In addition, instead of displaying the related position as an image such as a mark on a map image or characters indicating latitude / longitude, the audio output unit 45 processes the “photographing” The place is north latitude 35 北 24
"It is 138 ゜ 56 'east longitude", "The location is 35 ゜ 10' north latitude, 140 ゜ 25 'east longitude" and so on.

Further, the present invention may be configured such that any one of a method of displaying an image and a method of presenting by sound can be selected as a method of presenting a related position by operating the operation unit 16.

The fact that related position information is multiplexed,
Instead of being displayed with the mark 4 as shown in FIG. 7 (A), it is configured to be displayed in characters such as “capturing location can be displayed”, “accurate location can be displayed” or the like. Is also good.

Further, the fact that the related position information is multiplexed is not displayed in the form of an image such as a mark or a character, but is output from the sound output device 45 by the processing in the audio processing unit 43. It may be configured to be presented by voice such as "I can show the exact location".

Further, by operating the operation unit 16, as a method of presenting that the related position information is multiplexed, either a method of displaying an image or a method of presenting by sound can be selected. Alternatively, it may be configured.

Further, the presentation that the related position information is multiplexed may be configured to be turned on / off by an operation on the operation unit 16.

In this case, when the viewer instructs reproduction of the related position information while the presentation is switched off,
If the relevant position information is not multiplexed at that time, the system controller 17 controls the video processing unit 33 or the audio processing unit 43 to indicate that the relevant position cannot be presented because the relevant position information is not multiplexed. , May be configured to be displayed in an image or presented in a sound to alert the viewer.

Further, the configuration may be such that the related position information is not multiplexed itself, and is not particularly presented.

A method of presenting the relevant position (image display or audio output), a display format for displaying the relevant position as an image (map display format or a latitude / longitude direct display format), and a scale of the map for displaying the map And the position and size, whether or not the related position information is multiplexed, and the presentation method (image display or audio output) for the presentation, etc., are bothersome for the viewer to instruct each time. In order to avoid this, one of the system controller 17
The system controller 1 is set in the storage unit within the system controller 1 according to the instruction only when the viewer tries to change it.
7 may be changed.

On the broadcast side, for example, information indicating an altitude such as "586 m above sea level" of a place where a scene is recorded can be multiplexed with content as part of related position information and broadcast.

In this case, for example, according to the altitude information, the altitude of the related position such as "586 m above sea level" is displayed near the mark 6 on the map image 5 as shown in FIG. It is displayed in characters, or "The shooting location is
The receiving device is configured such that the latitude, longitude, and altitude of the related position are displayed in characters, such as "5 ゜ 24 ', east longitude 138 ゜ 56', altitude 586m".

The viewer fetches a new version of the map information into the external storage device 81 by a personal computer or the like, attaches or connects the external storage device 81 to the broadcast receiving device, and transmits the map information to the system controller 17 from the operation unit 16. Instruct update of map information.

Thus, the system controller 17
Reads out a new version of map information from the external storage device 81 and stores it in the map information storage device 73 instead of the map information stored in the map information storage device 73.

(Third Example of Broadcast Receiving Apparatus: FIG. 3) The system may be configured such that the map information is transmitted via a communication network separately from the broadcast.

FIG. 3 shows an example of this case. In this example, map information is distributed as data such as a Web (World Wide Web) page from a broadcasting station or a transmission source such as another distribution company by a communication network 1 such as the Internet.
