FIG. 54 is a flowchart for explaining the recording operation of the receiver 50 according to the tenth embodiment of the present invention. 54, the description of the operation similar to the recording operation of the receiver 50 according to Embodiment 2 shown in FIG. 12 is simplified.
In the recording operation of the receiver 50, as shown in FIG. 54, first, the transmission path decoding unit 52 performs transmission path decoding on the broadcast wave received from the broadcast station 1, and the separation unit 53 receives the multiplexed data subjected to transmission path decoding. The program data and the data broadcast content are separated (steps ST541 and 542).

  Next, analysis unit 61 detects a recording reservation script to which initial broadcast time information is added from the data broadcast content separated by separation unit 53 (step ST543). The recording reservation script to which the initial broadcast time information detected by the analysis unit 61 is added is transmitted to the reservation script processing unit 81.

Next, when receiving the recording reservation script to which the initial broadcast time information is added from the analysis unit 61, the reservation script processing unit 81 confirms this description and transmits it to the recording management unit 55, and is designated by the broadcasting station 1. An instruction to record an unrecorded part of the recorded program is given (step ST544).
Next, the recording manager 55 makes a recording reservation (step ST545). In addition, the recording management unit 55 notifies the reservation script processing unit 81 that the recording reservation has been completed.

  As described above, according to the tenth embodiment, when a part of a program is failed to be recorded in the receiver 50, the recorded start / end time information is sent to the broadcast station 1, and the broadcast station 1 Since the program is rebroadcasted, the receiver 50 can be additionally recorded except for the recorded amount.

  In the broadcast system according to the tenth embodiment, the recorded start / end time information is added to the broadcast desired program information acquisition script, and the initial broadcast time information is added to the recording script to make the receiver 50 make a recording reservation. The cases up to here have been described, but it may be a form in which the recorded start / end time information is added to the broadcast desired program information acquisition script and the broadcast station 1 forms a program for rebroadcasting of the unrecorded portion. .

  In the broadcast system according to the tenth embodiment, for example, when the initial broadcast time of a program is 8:00 to 10:00, only 8:30 to 9:30 is recorded. The recording reservation script shown in FIG. 5 may be described twice, from 8:00:00 to 8:30, 9:30 to 10:00, or may be a recording reservation script that can describe all time zones.
