Abstract

<P>PROBLEM TO BE SOLVED: To provide a digital broadcasting receiver which can view and listen data through a communication server irrespective of a state of the communication server when the program is reproduced if the data broadcasting which are simultaneously viewed and listened at the same time of the video recording, are the data acquired from the communication server. <P>SOLUTION: The digital broadcasting receiver comprises a means for receiving the digital broadcasting signal; a means for separating the receiving signal into a video signal and voice signal, and a data broadcasting content; a means for recording the data broadcasting content in a recording device; a means for taking in the data broadcasting content recorded in the external recording device; a means for taking in the broadcasting content through communication; and a means for indicating the data which are taken in by the broadcasting or the communication. The digital broadcasting receiver also comprises a means which records acquired communication data, a means for taking in the recorded communication data, and a means for recording relating information of the broadcasting program and the communication data. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a digital broadcast receiver that records and displays data sent by data broadcasting and data acquired through communication internally or by other devices.

When data broadcasting is received and used by digital broadcasting, in addition to displaying only the data existing in the broadcasting data, the data broadcasting is placed on an external communication server, and the receiver uses the data broadcasting description. Therefore, it is possible to acquire and display data from an external server via communication as necessary. On the other hand, it is possible to record on an external recording device such as D-VHS while viewing the data broadcast being received, and the recorded data broadcast can be reproduced and viewed later.
JP 2002-152615 A

  Conventionally, when the data broadcast recorded in the D-VHS or the like is reproduced later and the data broadcast is displayed, if the data displayed at the time of recording is the data acquired through communication, the communication is performed again. I'm going to get it via, but I don't know if the data on the communication server is the same as when it was broadcast. In addition, the communication server itself may not exist. In such a case, the data broadcast that could be displayed when the video was recorded cannot be seen, or the content that was being watched when the video was recorded is different.

  The present invention solves such a conventional problem. When the data broadcast viewed while recording is data acquired from the communication server, the recorded program is reproduced regardless of the state of the communication server. An object of the present invention is to provide a digital broadcast receiver capable of viewing data via a communication server.

  The digital broadcast receiver of the present invention comprises: means for receiving a digital broadcast signal; means for separating the received signal into a video signal, an audio signal, and data broadcast content; and means for recording the data broadcast content in a recording device; In the digital broadcast receiver comprising means for capturing the data broadcast content recorded in the recording device, means for capturing the data broadcast content via communication, and means for displaying the data captured in the previous period broadcast or communication, the acquired communication The present invention is characterized by comprising means for recording data, means for capturing the recorded communication data, and means for recording related information of the broadcast program and the communication data.

  According to the present invention, the displayed communication data and the related information of the broadcast program are recorded, and by displaying the communication data appropriately recorded using the related information, the corresponding content can be deleted from the communication server, or on the communication server. Even if the data is replaced with different data, the communication data broadcast viewed at the time of recording can be viewed and the utility value can be improved.

(Embodiment)
FIG. 1 is a diagram showing a basic configuration of a digital broadcast receiver according to an embodiment of the present invention. In FIG. 1, 101 is a TS separation unit, 102 is a TS recording unit, 103 is a data analysis unit, 104 is a data display unit, 105 is a communication data acquisition unit, and 106 is a data recording unit.

  A recording flow in the apparatus of FIG. 1 will be described with reference to FIG.

  In FIG. 2, a TS signal 201 input as a Transport Stream signal (TS signal) multiplexed with a video signal or an audio signal is separated into a video stream, an audio stream, and a data stream by a TS separation unit 202. The separated data stream is sent to the data analysis unit 103. The input TS signal is simultaneously sent to the TS recording unit 205 and recorded there. The data analysis unit 203 examines the BML document inside the data and creates display data according to the description of the BML document. When the URL scheme described in the A tag or document transition extension function is http or https according to the description of the BML document, the communication data acquisition unit 207 acquires the communication data 206 from the external communication server. The communication data acquired by the communication data acquisition unit 207 is sent to the data analysis unit 203, and the data analysis unit 203 creates display data. Communication data acquired at the same time is sent to the data recording unit 208 and recorded by the data recording unit 208. At the same time, the program information, the original URL, and the association data relating the new storage destination URL are also recorded. The display data created by the data analysis unit 203 is sent to the data display unit 204 and displayed on the display screen.

  Next, the flow during reproduction by the apparatus of FIG. 1 will be described with reference to FIG.

  In FIG. 3, the TS signal reproduced from the TS recording unit 302 is separated into a video stream, an audio stream, and a data stream by the TS separation unit 301. The separated data stream is sent to the data analysis unit 303. The data analysis unit 303 examines the BML document inside the data and creates display data according to the description of the BML document. When the URL scheme described in the A tag or document transition extension function is http or https according to the description of the BML document, association data is taken out from the data recording unit 306, program information described there, When the original URLs match, the data of the storage destination URL is taken out from the data recording unit 306, the data analysis unit 303 examines the BML document inside the data, and creates display data according to the description of the BML document. The display data created by the data analysis unit 303 is sent to the data display unit 304 and displayed on the display screen.

  The digital broadcast receiver of the present invention records the displayed communication data and related information of the broadcast program, and displays the communication data appropriately recorded using the related information, so that the corresponding data is erased from the communication server. Even if it is replaced with different data on the communication server, the communication data broadcast viewed at the time of recording can be viewed and the utility value can be improved, which is useful as a TV or a set-top box.
