With the above operations, the recording reservation process of the broadcast receiving apparatus 100 is completed.

[Operation sequence during scheduled recording]
Next, the operation of the scheduled recording process based on the reservation information table stored in the reservation information storage area 1200 in the broadcast receiving apparatus 100 of this embodiment will be explained. FIG. 8 is an operation sequence diagram illustrating an example of the operation of the scheduled recording process of the broadcast receiving apparatus 100 of this embodiment.

While the broadcast receiving apparatus 100 is in operation or on standby, the program recording execution unit 1104 appropriately records the time information of the built-in clock (not shown) and the reservation information table in the reservation information storage area 1200 under the control of the basic operation execution unit 1101. Confirm (S801). When the broadcast start date and time of the broadcast program to be reserved for recording stored in the reservation information table approaches, the basic operation execution unit 1101 performs startup processing and initialization processing for the broadcast receiving apparatus 100 (S802). Note that if the broadcast receiving apparatus 100 is already in operation, the process of S802 is unnecessary. After the startup process and initialization process are completed, the broadcast program playback unit 1102a of the reception function execution unit 1102 receives the digital broadcast wave (S803), and the tuner/demodulation unit 131 selects the scheduled recording target. Processing for tuning (tuning) to the channel of the broadcast program to be broadcasted, processing for demodulating the modulated signal, etc. are performed (S804). Note that the process in S804 may be performed by appropriately selecting an available tuner when the broadcast receiving apparatus 100 is already in operation and is selecting an arbitrary broadcast program that is not subject to scheduled recording. Furthermore, the video of the broadcast program to be scheduled for recording may not be displayed on the video display section 163.

After completing the process of tuning to the channel of the broadcast program targeted for scheduled recording, the program recording execution unit 1104, under the control of the receiving function execution unit 1102, selects the scheduled recording target superimposed on the digital broadcast wave. The program identification information and program content storage location information related to the broadcast program are acquired (S806). Note that the program identification information and program content storage location information may be included in the PSI or SI. It may be included in the AIT used for the broadcast communication cooperation function. It may be included in a BML data string used for data broadcasting. It may also be transmitted by being included in the digital broadcast wave together with the program content of the broadcast program by other methods. Alternatively, the information may be obtained by accessing a predetermined server device designated by the AIT of the broadcast communication cooperation function.

The program identification information and the program content storage location information regarding the broadcast program to be reserved for recording acquired in the process of S806 are written in the reservation information table of the reservation information storage area 1200 referred to in the process of S801. Under the control of the program recording execution unit 1104, the information is stored in the recorded program information table of the recorded content storage area 1300 (S807). Specifically, for example, the acquired program identification information is stored in the recorded program identification information 1307 of the recorded program information table. The acquired program content storage location information is stored in the recorded program content storage location information 1308. Also, the broadcast date information 1202, broadcast time information 1203, broadcast channel information 1204, broadcast program title information 1205, and recording/viewing mode 1207 of the reservation information table in the reservation information storage area 1200 are the same as the recording date information 1302 of the recorded program information table. It is stored in recording time information 1303, recording channel information 1304, recording program title information 1305, and recording mode 1306.

After completing the process of S807, the reservation management execution unit 1103 deletes the reservation information stored in the reservation information table of the reservation information storage area 1200 (S808). With the above operations, the scheduled recording process of the broadcast receiving apparatus 100 is completed.

The above-mentioned series of processes is an example of the process when the "Program save" key is set to "No" in the reservation setting key 163b3 of the program detailed information display screen 163b. This is an example of a case where program content related to a program is not stored in the storage of the broadcast receiving device 100. When the "Program Save" key is set to "Yes", the broadcast receiving apparatus 100 of this embodiment, in the process of S807, may leave the program content (TS or ES) output from the separation unit 132 as it is, or After the program content is transcoded by the content processing unit 151 according to the settings of the "recording mode" key of the reservation setting key 163b3, it is transferred to the storage specified by the "recording destination" key of the reservation setting key 163b3 (for example, The process may be performed so as to be stored in the recorded content storage area 1300 of the storage unit 110 or the HDD connected to the expansion I/F unit 124.

In addition, as described above, whether or not to prevent the program content of the broadcast program that is the target of reserved recording from being stored in the storage of the broadcast receiving device 100 is determined by "Program It may be possible to switch according to the setting of the "Save" key, but whether program identification information regarding the broadcast program targeted for the scheduled recording and program related information of the program content storage location information are superimposed on the digital broadcast wave. It may be possible to automatically switch depending on whether or not. That is, for example, if program identification information and program content storage location information regarding the broadcast program targeted for scheduled recording are superimposed on digital broadcast waves, the program identification information regarding the broadcast program targeted for scheduled recording is To prevent program contents from being stored in the storage of a broadcast receiving device 100. In addition, if the program identification information and the program content storage location information related to the broadcast program targeted for scheduled recording are not superimposed on the digital broadcast wave, the program content related to the broadcast program targeted for scheduled recording is is stored in the storage of the broadcast receiving device 100.

Further, in this case, it is preferable to make it possible to visually check whether the program identification information and program related information of the program content storage location information regarding each broadcast program are superimposed on the digital broadcast wave in the program information 163a1 of the EPG display screen 163a. . For example, the program information 163a1 of a broadcast program in which program identification information and program content storage destination information are superimposed on digital broadcast waves is indicated by adding text, symbols, illustrations, different background colors, etc. Make it clear.

Further, in S803, the broadcast program playback unit 1102a may receive broadcast waves only for a predetermined period (for example, one minute from the start of the program). Further, if the program identification information 1307 and the program storage location information 1308 regarding the broadcast program to be reserved for recording are transmitted at predetermined intervals (for example, 15 seconds), the broadcast program playback unit 1102a may receive digital broadcasting only for the corresponding interval (for example, 15 seconds). This allows the tuner to be opened quickly.

Furthermore, if reservation information for a plurality of broadcast programs whose broadcast times 1203 overlap are stored in the reservation information table, the broadcast waves of each broadcast program may be received in a circular manner in S803.

Furthermore, if the recording process is performed by manual operation while viewing a broadcast program instead of the reserved recording process based on the reservation information table stored in the reservation information storage area 1200, the processes of S801 and S808 are not necessary. While viewing the broadcast program selected in the process of S804, the user operates a remote controller (not shown) to instruct manual recording (S805), and the processes of S806 to S807 are subsequently executed. good.

[Operation sequence when playing recorded program]
Next, a description will be given of the operation of the playback process for recorded programs based on the recorded program information table stored in the recorded content storage area 1300 in the broadcast receiving apparatus 100 of this embodiment. FIG. 9 is an operation sequence diagram illustrating an example of the operation of the recorded program playback process of the broadcast receiving apparatus 100 of this embodiment.

When the broadcast receiving apparatus 100 of this embodiment performs the recorded program playback process, the user first operates a remote controller (not shown) to instruct the broadcast receiving apparatus 100 to turn on the power (S901). The broadcast receiving apparatus 100 that has received the power-on instruction from the remote controller performs startup processing and initialization processing under the control of the basic operation execution unit 1101 (S902). Note that if the broadcast receiving apparatus 100 has already been activated, the processes of S901 and S902 are not necessary. After the startup processing and initialization processing, when the user operates the remote controller to instruct display of a list of recorded programs (S903), the reception function execution unit 1102 displays a display screen of the list of recorded programs on the video display unit 163. (S904).

FIG. 10 is a screen display diagram illustrating an example of a recorded program list display screen displayed in the process of S904. The recorded program list display screen 163c displays a list of recorded program information 163c1 of each recorded program stored in the recorded program information table of the recorded content storage area 1300 and an operation guide 163c6. The recorded program information 163c1 mainly includes a thumbnail section 163c2 and a program summary section 163c3 that displays information such as the recorded program title, recording date and time, recording channel, recording mode, recording time, and the like. Furthermore, the recorded program information 163c1 includes an unviewed mark 163c4 indicating whether each recorded program has not been viewed yet, and a cloud mark indicating whether the program content related to each recorded program is stored in the storage of the broadcast receiving device 100. 163c5 as appropriate. Note that the cloud mark 163c5 is displayed when the program content related to each recorded program is not stored in the storage of the broadcast receiving device 100. That is, the cloud mark 163c5 is displayed when the program content regarding each recorded program is not stored in the storage of the broadcast receiving device 100. This is displayed when the "Save" key is set to "No" and the scheduled recording process is performed.

The program selection cursor 163c7 can be moved by operating a cursor key on a remote controller (not shown). Furthermore, by pressing the enter key on the remote control, it is possible to start the reproduction process of the recorded program selected by the program selection cursor 163c7.

On the recorded program list display screen 163c displayed in the process of S904 in FIG. reads the recorded program identification information 1307, recorded program content storage location information 1308, and recording mode 1306 of the predetermined recorded program from the recorded program information table stored in the recorded content storage area 1300 (S906).

The reception function execution unit 1102 interprets the recorded program content storage location information 1308 read in the process of S906, and selects a content server (in this embodiment, the service provider server 400) in which the video content related to the predetermined recorded program is stored. information (for example, IP address information, etc.) for identifying on the network. Further, the receiving function execution unit 1102 transmits the recorded program identification information 1307 and the recorded program regarding the predetermined recorded program to the service provider server 400 identified by the extracted IP address information via the LAN communication unit 121. Content storage location information 1308 and recording mode 1306 are transmitted to request transmission of video content regarding the predetermined recorded program (S907). Note that if the recorded program content storage location information 1308 includes only IP address information, there is no need to transmit the recorded program content storage location information 1308 in the process of S907.

The basic operation execution unit 4101 of the service provider server 400 uses video content management/recording program identification information 1307, recorded content storage location information 1308, and recording mode 1306 regarding the predetermined recorded program received via the LAN communication unit 421. It is transmitted to the distribution execution unit 4102. The video content management/distribution execution unit 4102 refers to the content information table stored in the metadata storage area 4200 based on the received recorded program identification information 1307. Further, by acquiring content storage location information 4202 and content name 4203 corresponding to program identification information 4201 that matches the received recorded program identification information 1307, video content related to the predetermined recorded program is selected (S908). . Instead of obtaining the content storage location information 4202 and content name 4203, directory information and file names obtained by interpreting the received recorded content storage location information 1308 may be used.

Next, the video content management/distribution execution unit 4102 refers to the video content storage area 4300 based on the content storage location information 4202 and content name 4203 acquired in the process of S908, and stores the video content related to the predetermined recorded program. read out. Further, the video content management/distribution execution unit 4102 performs transcoding processing on the read video content according to the received recording mode 1306 (S909), and transmits the video content to the broadcast receiving apparatus 100 via the LAN communication unit 421. (S910). Note that instead of the transcoding process in S909, a plurality of video contents with different bit rates are prepared in advance in the video content storage area 4300, and the video content with a predetermined bit rate is prepared according to the received recording mode 1306. You may also choose. Furthermore, if there is sufficient margin in the communication band between the service provider server 400 and the broadcast receiving device 100, the transcoding process in S909 may not be performed. The presence or absence of the transcoding process may be switched depending on the network situation between the service provider server 400 and the broadcast receiving device 100.

The broadcast receiving apparatus 100, which has received the video content related to the predetermined recorded program transmitted from the service provider server 400, transmits the video content received via the LAN communication unit 121 based on the control of the reception function execution unit 1102. It is transmitted to the separation unit 132. Further, based on the control of the broadcast program playback section 1102a, separation processing of each data string in the separation section 132, decoding processing of the video data string and audio data string in the video decoding section 133 and the audio decoding section 134, etc. are performed. The video signal and audio signal of the broadcast program are output from the video display section 163 and the speaker 164 via the superimposition section 161 and the audio selection section 162 (S911). Through the above operations, the recorded program playback process of the broadcast receiving apparatus 100 is realized.

As described above, the operations of recording reservation processing, reservation recording processing, and recorded program playback processing are explained above, in the broadcast receiving apparatus 100 of this embodiment, when recording a broadcast program, In addition, there is no need to separately store program content related to a broadcast program in the storage of the broadcast receiving device 100, and content related to a recorded broadcast program is acquired from a content server on the network each time it is played back. However, unlike a known VOD (Video On Demand) system in which the user accesses a content server himself to search/select desired content, in the broadcast receiving apparatus 100 of this embodiment, the user is not aware of the existence of the content server. There is no need for this, and it is possible to achieve the same usability as a conventional VTR (Video Tape Recorder) regarding recording and playback processing of broadcast programs. Furthermore, in the broadcast receiving apparatus 100 of this embodiment, the recorded program information table that manages information on recorded programs does not require a large storage area, and therefore, it is possible to manage/store a large number of recorded programs. Alternatively, it is possible to manage with a small capacity storage. That is, it is possible to provide a broadcast receiving device that enables more useful recording processing and playback processing.
