BACKGROUND OF THE INVENTION
The present invention relates to a data broadcast reproduction system, a data broadcast receiving apparatus, and a data broadcast reproduction program capable of reproducing a recorded data broadcast program, and more particularly to displaying newer content when a recorded program is reproduced. The present invention relates to a data broadcast reproduction system, a data broadcast reception device, and a data broadcast reproduction program.
[0002]
[Prior art]
In television broadcasting, a television signal including a video signal and an audio signal is transmitted. The receiver receives a television signal and outputs video and audio. In recent years, data broadcasting has been realized in which not only video and audio but also information related to a broadcast program is displayed on a receiver. Hereinafter, the contents of this information are referred to as contents, and are distinguished from the contents of video and audio signals based on video signals. The viewer can browse content related to the program in addition to video and audio by using the data broadcast receiving apparatus. For example, in a data broadcast of a sports broadcast program, it is possible to browse content indicating the results of each player. In addition, for example, in a TV shopping program, it is possible to browse content indicating more detailed guidance of introduced products.
[0003]
The data broadcasting signal is a signal obtained by multiplexing content data on a television signal. Content data is multiplexed in a portion corresponding to VBI (Vertical Blanking Intervals) in which no video signal exists in analog broadcasting. In the case of digital broadcasting, content data is multiplexed into MPEG2-TS (Moving Picture Experts Group 2-Transport Stream).
[0004]
In data broadcasting in analog terrestrial broadcasting, content data is described in, for example, HTML (Hypertext Markup Language). Examples of data broadcasting that describes content data in HTML include bitcast and ADAMS. “bitcast” is a name of a data broadcasting method developed by Infocity Corporation. ADAMS is the name of a data broadcasting system performed by affiliated broadcasting stations of TV Asahi Corporation. In data broadcasting in digital broadcasting, content data is described in, for example, BML (Broadcasting Markup Language).
[0005]
The data broadcast receiving apparatus separates the video signal, audio signal, and content data from the received signal. Then, the video is displayed by the video signal, and the audio is output by the audio signal. The data broadcast receiving apparatus includes a browser, analyzes the content data, and displays the content using the browser.
[0006]
In accordance with the operation of the viewer, the data broadcast receiving apparatus may record (record) a data broadcast program or the like on a recording apparatus such as a video tape recorder, and may reproduce it later. The data broadcast receiving device reads a recorded signal from the recording device when reproducing a recorded program or the like. Then, the video signal, audio signal, and multiplexed content data are separated from the signal, and video display, audio output, and content display are performed.
[0007]
[Problems to be solved by the invention]
When reproducing a signal recorded in a recording device, a conventional data broadcast receiving device displays content at the time when a program or the like is broadcast. It is desirable for the viewer to be able to view the latest content even when viewing a recorded program. In particular, if the period during which the content has value is limited or the value of the content decreases with the passage of time, the viewer desires to view the latest content. For example, it is assumed that data of a content “The product A is sold for a limited time until August 31” is multiplexed in a data broadcast of a program. When the viewer records this program and plays it back in September, the value of the content is reduced at the time of playback. This viewer desires to browse content according to the time when the program is played.
[0008]
It is an object of the present invention to provide a data broadcast reproduction system, a data broadcast reception device, and a data broadcast reproduction program that can display newer contents when reproducing recorded data broadcast signals.

[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of a data broadcast reproduction system and a data broadcast receiver according to the present invention. The data broadcast reproduction system includes a data broadcast receiving device 1 and a data server (data holding device) 21. The data broadcast receiving apparatus 1 and the data server 21 are connected by a LAN 41 and transmit / receive information according to a standard such as 100BASE-TX, for example. The 100BASE-TX shown here is an example, and other standards may be followed. The data broadcast receiving device 1 and the data server 21 may be connected not by the LAN 41 but by another communication network.
[0018]
The data server 21 is connected to an update data transmission device 31 managed by a data broadcasting broadcast station via a communication network such as the Internet 42. The update data transmission device 31 transmits update data (data updated in the content) to the data server 21 when the content of the data broadcast is updated. For example, it is assumed that data of a content “The product A is sold for a limited time until August 31” is multiplexed in a data broadcast of a program. After that, when the broadcast station updates the content to the content “Product B will be sold at a discount price after September.”, The update data transmission device 31 transmits the update data to the data server 21. The data server 21 holds update data.
[0019]
The data broadcast receiving apparatus 1 receives a data broadcast signal and outputs video, audio, and content. Further, by recording the received signal, a data broadcast program or the like is recorded. When playing back a recorded program or the like, the data broadcast receiving apparatus 1 determines whether or not there is a possibility of updating the content on the broadcast station side corresponding to the content data included in the recorded signal. Here, the content on the broadcast station side is content that is multiplexed with a data broadcast signal when the broadcast station broadcasts a program or the like. If there is a possibility that the content on the broadcast station side has been updated, the data broadcast receiving apparatus 1 checks whether or not the update data is held in the data server 21. If the update data is held, the data broadcast receiving apparatus 1 acquires the data and outputs the updated content together with video and audio.
[0020]
When broadcasting a program or the like, the broadcasting station adds identification information indicating whether or not the content is likely to be updated to the content data and transmits a data broadcasting signal.
[0021]
Next, an example of the configuration of the data broadcast receiving apparatus 1 will be described.
In the data broadcast receiving apparatus 1, the control unit 2 controls the entire data broadcast receiving apparatus 1. The control unit 2 includes a CPU 3, a RAM 4, and a ROM 5. The RAM 4 or the ROM 5 stores a program for performing various calculations and controlling the entire data broadcast receiving apparatus 1 and a browser program. The CPU 3 performs various calculations and control of the entire data broadcast receiving apparatus 1 according to programs stored in the RAM 4 or the ROM 5. The network interface unit 6 transmits and receives information to and from the data server 21 via a communication network such as the LAN 41. The tuner 7 receives a data broadcast signal on which content is multiplexed by an antenna 8.
[0022]
The recording device 9 records a signal such as a program broadcast as a data broadcast. The recording device 9 is configured by, for example, a video tape recorder, a hard disk drive, or the like.
[0023]
The data broadcast decoder 10 separates the video signal, the audio signal, and the content data from the data broadcast signal received by the tuner 7 under the control of the CPU 3. Then, the encoded video signal, audio signal, and content data are decoded.
[0024]
Content data described in HTML, BML, or the like is analyzed by the CPU 3. The data synthesizing device 11 synthesizes both images so that the content image obtained as a result of the analysis by the CPU 3 and the image obtained by the video signal are displayed on one screen. For example, the video signal of the screen showing the image of the content and the video based on the video signal is created so that the video based on the video signal is displayed on the left side of the screen and the content is displayed on the right side. The video display device 12 displays a content image and a video based on the video signal based on the video signal created by the data synthesis device 11.
[0025]
The input device 13 is constituted by, for example, a mouse, a keyboard, a switch, and the like, and an instruction for a display screen or the like is input. For example, the viewer inputs an instruction to change the content display area, the size or position of the video display area by the video signal, an instruction to display only one of the content or the video by the video signal, or the like. . When these instructions are input to the input device 13, the CPU 3 controls the data synthesizing device 11 so that a video signal of a screen corresponding to the instruction content is output. The data synthesizer 11 creates a video signal for a screen that displays content and video based on the video signal, under the control of the CPU 3. For example, when an instruction to reduce the content display area is input to the input device 13, the data synthesis device 11 creates a video signal of a screen with a reduced content display area according to the control of the CPU 3.
[0026]
The audio output unit 14 outputs audio based on the decoded audio signal. The audio output unit 14 includes an amplifier 15 and a speaker 16. The amplifier 15 amplifies the sound signal, and the speaker 16 converts the sound signal into sound and outputs the sound.
[0027]
The recording device 9, the video display device 12, the input device 13, and the audio output unit 14 may be provided in the data broadcast receiving device 1 as shown in FIG. Or the structure provided outside the data broadcast receiving apparatus 1 and connected to the data broadcast receiving apparatus 1 from the outside may be sufficient.
[0028]
Next, an example of the configuration of the data server 21 will be described.
In the data server 21, the control unit 22 controls the entire data server 21 according to a program stored in the storage device 23. The storage device 23 stores a program that controls the entire data server 21. The network interface unit 24 transmits / receives information to / from the data broadcast receiving apparatus 1 and the update data transmitting apparatus 31 via a communication network such as the LAN 41 and the Internet 42.
[0029]
The database 25 holds update data. When the control unit 22 receives the update data from the update data transmission device 31, the control unit 22 registers the data in the database 25.
[0030]
Update data is input to the update data transmission device 31 by the broadcasting station. The update data transmission device 31 transmits the input data to the data server 21.
[0031]
Next, an operation when the data broadcast receiving apparatus 1 receives a data broadcast signal will be described. FIG. 2 is a flowchart showing an example of an operation when the data broadcast receiving apparatus 1 receives a data broadcast signal and outputs a video or the like.
[0032]
The broadcast station adds identification information indicating whether or not the content is likely to be updated to the data of the content. Information such as a program corresponding to the content is also added. And the signal which multiplexed the content to which such information was added is transmitted. The tuner 7 receives a data broadcast signal through the antenna 8 (step S71). Subsequently, the data broadcast decoder 10 separates the video signal, audio signal, and content data from the signal received by the tuner 7 under the control of the CPU 3, and decodes the separated video signal, audio signal, and content data (step). S72). The data broadcast decoder 10 outputs the decoded video signal, audio signal, and content data to the data synthesizer 11, the audio output unit 14, and the CPU 3, respectively.
[0033]
Next, the CPU 3 analyzes the content data (step S73). That is, data described in HTML, BML, or the like is analyzed to determine how the content is displayed. The CPU 3 outputs content image information to the data composition device 11. The data synthesizer 11 creates a video signal for displaying the content image and the video based on the video signal on one screen in accordance with the control of the CPU 3 (step S75).
[0034]
The video display device 12 displays content and video based on the video signal based on the video signal created by the data synthesis device 11. The amplifier 15 of the sound output unit 14 amplifies the sound signal decoded in step S72, and the speaker 16 converts the sound signal into sound and outputs the sound (step S75). If a viewer instruction is input from the input device 13, the CPU 3 controls the data synthesis device 11 so as to create a video signal of a screen corresponding to the input instruction.
[0035]
When the viewer performs an operation of recording a data broadcast program, the CPU 3 outputs a data broadcast signal received by the tuner 7 to the recording device 9. The recording device 9 records the input data broadcast signal.
[0036]
Next, an operation when the data server 21 registers the updated content data will be described. The broadcast station inputs update data to the update data transmission device 31 when the content related to the already broadcasted program is updated. The broadcasting station adds information such as a corresponding program to the update data. That is, information indicating which program or the like the update data corresponds to is added. The update data transmission device 31 transmits update data to the data server 21 in accordance with the operation of the broadcast station. The control unit 22 of the data server 21 receives update data from the update data transmission device 31 via the Internet 42. Then, the control unit 22 holds the received data in the database 25.
[0037]
Next, the operation of the data broadcast reproduction system when reproducing the recorded signal will be described. FIG. 3 is a flowchart showing an example of the operation of the data broadcast reproduction system when the data broadcast signal recorded in the recording device 9 is reproduced. The CPU 3 causes the data broadcast decoder 10 to read the data broadcast signal recorded in the recording device 9 (step S81). The data broadcast decoder 10 separates the video signal, audio signal, and content data from the read signal under the control of the CPU 3, and decodes the separated video signal, audio signal, and content data (step S82).
[0038]
The CPU 3 analyzes the data of the decrypted content, and determines whether there is a possibility that the content on the broadcast station side corresponding to the content has been updated (step S83). This determination is made based on identification information added to the content (identification information indicating the possibility of being updated). That is, if the identification information indicates that there is a possibility of updating, the CPU 3 determines that the content may be updated. On the other hand, if the identification information indicates that there is no possibility of updating, the CPU 3 determines that the content is not likely to be updated.
[0039]
If there is a possibility of updating, the CPU 3 requests the data server 21 to check whether or not the update data is held (step S84). The CPU 3 extracts information such as a program corresponding to the content from the content data, and transmits the information to the data server 21 in step S84.
[0040]
If there is no possibility of updating, the data broadcast receiving apparatus 1 displays the content based on the content data separated and decoded in step S82. Following step S83, the data broadcast receiving apparatus 1 performs the same operation as steps S73 to S75. The case where there is a possibility of updating will be described below.
[0041]
In step S84, the control unit 22 of the data server 21 receives information such as a program corresponding to the content. The control unit 22 checks whether or not update data corresponding to the program or the like is held in the database 25. Since information indicating which program or the like corresponds to each update data held in the database 25, the control unit 22 can perform the confirmation requested in step S84. The control unit 22 transmits the confirmation result to the data broadcast receiving device 1 (step S85). The CPU 3 receives this confirmation result.
[0042]
If it is confirmed that the update data is stored in the data server 21, the CPU 3 requests the data server 21 to transmit the update data (step S86).
[0043]
If the update data is not held, the data broadcast receiving apparatus 1 displays the content based on the content data separated and decoded in step S82. Following step S85, the data broadcast receiving apparatus 1 performs the same operations as steps S73 to S75. Hereinafter, a case where update data is held will be described.
[0044]
In response to the request in step S86, the control unit 22 of the data server 21 extracts update data from the database 25 and transmits it to the data broadcast receiving device 1 (step S87). The CPU 3 receives the update data.
[0045]
Subsequently, the CPU 3 replaces the updated portion of the content data separated and decrypted in step S82 with the updated data (data received in step S87) (step S88). The CPU 3 analyzes how the content with the replaced data is displayed (step S89), and outputs information on the content image to the data synthesis device 11. The data synthesizing apparatus 11 creates a video signal for displaying the content image and the video based on the video signal decoded in step S82 on one screen (step S90). The video display device 12 displays content and video based on the video signal based on the video signal created by the data synthesis device 11. Moreover, the audio | voice output part 14 outputs an audio | voice based on the audio | voice signal decoded in step S82 (step S91). The operations in steps S89 to S91 are the same as the operations in steps S73 to S75.
[0046]
As described above, if the update data is held in the data server 21, the data broadcast receiving device 1 receives the data from the data server 21. Then, the content is displayed using the update data. Therefore, the viewer can browse newer content even when the recorded program is reproduced.
[0047]
Next, another embodiment of the present invention will be described. In this embodiment, the updated content is displayed when the condition specified by the viewer is met. Hereinafter, an example will be described in which a viewer designates a field of a program as a condition, and the data broadcast reproduction system displays updated content in the designated field. The configurations of the data broadcast reproduction system and the data broadcast receiving apparatus according to the present embodiment are the same as those shown in FIG.
[0048]
In the present embodiment, the broadcast station also adds identification information indicating a field such as a program to the content data. For example, identification information indicating fields such as “sports” and “documentary” is added to content data related to sports programs and documentary programs, respectively. The broadcasting station transmits a signal in which content data to which such identification information is added is multiplexed. When the data broadcast receiving device 1 records a data broadcast signal in the recording device 9, this identification information is also recorded.
[0049]
In addition, the viewer designates which field of the program or the like he / she wants to view the latest content, and stores the designated field in the RAM 4 or the like in advance. For example, a field such as “sports” is held as a field where the latest content is desired to be browsed. The field specified by the viewer is input to the input device 13, and the CPU 3 stores the input field in the RAM 4 or the like.
[0050]
When the data broadcast receiving apparatus 1 reproduces the recorded signal, it performs the same operation as steps S81 to S83, and determines whether or not there is a possibility that the content corresponding to the content to be reproduced has been updated. To do. However, in step S83, the CPU 3 extracts identification information indicating a field such as a program from the content data. Then, it is also determined whether or not the field designated by the viewer matches the field indicated by the identification information. When the fields match and there is a possibility of updating, the data server 21 is requested to confirm whether or not the update data is held. The operations after step S84 are the same as those described above.
[0051]
According to this embodiment, the data broadcast receiving apparatus displays the latest content only in the field designated by the viewer. For example, if only the field “sports” is designated, the latest content is displayed only when a program in the field “sports” is played. In this way, it is possible to determine whether or not to display the latest content according to the viewer's preference.
[0052]
Further, the data server 21 may include information on a field designated by the viewer. In this case, the data server 21 holds, in the database 25, a field designated by each viewer in advance corresponding to each viewer's ID (information specifying the viewer). For example, the viewer inputs the designated field and his / her ID to the input device 13, and the CPU 3 transmits the designated field and ID to the data server 21. The control unit 22 of the data server 21 stores the received field and ID in the database 25 in association with each other.
[0053]
When the update data is transmitted to the data server 21, information indicating the field of the program is also added to the update data. For example, when the content of a sports program is updated, information indicating the field “sports” is added to the updated data. As a result, the update data is held in the database 25 with information indicating the field added.
[0054]
The viewer inputs the ID to the input device 13 when reproducing the recorded program. The data broadcast receiving apparatus 1 performs the same operation as steps S81 to S84 when reproducing the signal recorded in the recording apparatus 9. However, in step S84, the viewer ID is also transmitted. The control unit 22 of the data server 21 confirms the presence or absence of update data as in step S85. However, even if update data is held, information on the field added to the data is extracted, and if the field does not match the field corresponding to the ID, update data is not held. Is transmitted to the data broadcast receiving apparatus 1. Therefore, the confirmation result that the update data is held is transmitted only when the update data is held and the field added to the data matches the field corresponding to the ID. The operation after the data server 21 transmits the confirmation result is the same as that described above.
[0055]
As a result, the data broadcast receiving apparatus 1 displays the latest content only for the field designated in advance by the viewer. Thus, also in this example, it is possible to determine whether or not to display the latest content according to the viewer's preference. In addition, the viewer can browse the latest content in the field designated by the viewer regardless of which data broadcast receiving device is used.
[0056]
Here, the case where the program field is specified as the condition has been described, but a condition other than the program field may be specified. For example, the program name may be designated as a condition, and the latest content may be displayed only for the designated program.
[0057]
In each of the above examples, the case where identification information indicating the possibility of updating is added to the multiplexed content data has been described, but other information may be added instead of this identification information. For example, broadcast date information may be added to content data that may be updated, and broadcast date information may not be added to content data that may not be updated. In step S83, the CPU 3 may determine the possibility of updating based on the presence / absence of broadcast date information. Further, if a predetermined period has elapsed from the broadcast date, it may be determined that there is a possibility of updating.
[0058]
  Further, the data server 21 may search for a WEB page that is designated by the data broadcast receiving apparatus 1 and matches the keyword. When the data broadcast receiving apparatus 1 analyzes the content data in step S83,ThatWords included in the content are extracted as keywords and transmitted to the data server 21 in step S84. The data server 21 searches for a WEB page that matches the received keyword in the same manner as the search engine, and transmits information on a screen for displaying the search result to the data broadcast receiving apparatus 1. The data broadcast receiving device 1 displays the search result screen on the video display device together with the video and content screens based on the video signal. At this time, the data synthesizer 11 creates a video signal for displaying the video based on the video signal, the content image, and the search result image in one screen, and causes the video display device 12 to display this screen.
[0059]
Thus, if the data server 21 searches the WEB page and the data broadcast receiving apparatus 1 displays the search result, the viewer can browse more information related to the program to be reproduced.
[0060]
  The storage means is realized by the recording device 9. The selection unit and the acquisition unit are realized by the CPU 3. The reproduction means is realized by the video display device 12.
