  The program information storage unit 191 (corresponding to program information storage means) stores program information of one physical channel received by the receiving unit 15. Specifically, the program information storage unit 191 stores the program information of one physical channel received by the receiving unit 15 for each of a plurality of subchannels included in one physical channel, and the channel number information and program of the subchannel. The name information is stored in association with each other.

  The recording execution unit 111 (corresponding to recording execution means) controls the program information of one physical channel received by the receiving unit 15 and the information received by the receiving unit 15 (= channel number information, program name information, etc.). Information), each subchannel included in one physical channel is recorded in the program information storage unit 191 in association with the channel number information and program name information of the subchannel.

  The subchannel display unit 112 (corresponding to the subchannel display means) displays the channel number information and program name information of the subchannel stored in the program information storage unit 191 in association with each other on the display 21.

  The subchannel changing unit 113 (corresponding to a part of the subchannel changing means) receives an operation input from the user via the remote controller 3, and is stored in the program information storage unit 191 based on the received operation input. The channel number information of the subchannel is changed, and the changed channel number information is overwritten and recorded in the program information storage unit 191.

  FIG. 3 is a screen diagram showing an example of a subchannel number change screen displayed on the display 21 by the subchannel display unit 112. (A) is the subchannel number change screen 400 before the channel number information is changed by the subchannel changing unit 113, and (b) is the screen after the channel number information is changed by the subchannel changing unit 113. It is a subchannel number change screen 410. The subchannel number change screen 400 before change shown in (a) includes a physical channel number display unit 401, a recording date display unit 402, a recording time display unit 403, and subchannel information display units 404 and 405 in order from the top. It is displayed.

  The physical channel number display unit 401 displays the physical channel number information of the program recorded in the program information storage unit 191. The recorded month / day display unit 402 displays the recorded month / day information of the program recorded in the program information storage unit 191. The recording time display unit 403 displays recording time information (= recording start time information and recording end time information) for each program recorded in the program information storage unit 191.

  For each subchannel recorded in the program information storage unit 191, the subchannel information display units 404 and 405 associate the subchannel number information and the program name information with the recording time information displayed on the recording time display unit 403. To display. Here, the program name information corresponding to the subchannel with the subchannel number “1” is “baseball broadcast” when the recording time is from 20:00 to 22:00, and “ XX drama ". Also, the program name information corresponding to the subchannel with the subchannel number “2” has no data (= indicating that no broadcast is being performed) between 20:00 and 22:00, and the recording time is 22:00. Between 3:00 and 23:00, it is “baseball broadcast (extension)”.

  That is, a broadcast station that transmits a broadcast wave with a physical channel “5” has a program (here, a baseball broadcast) of one subchannel (here, a subchannel with a channel number “1”) included in this physical channel. The program (in this case, an extended baseball broadcast program) extended with another subchannel (here, the subchannel with the channel number “2”) included in this physical channel. ).

  In this state, when a program with a physical channel of “5” and a subchannel number of “1” is played, first, “baseball broadcast” is played, and then “XX drama” is played. In order to view the extended “baseball broadcast”, it is necessary to reproduce the program whose physical channel is “5” and whose subchannel number is “2”. In other words, when the reproduction of “baseball broadcast” is completed, it is necessary to change the subchannel number to be reproduced from “1” to “2”.

  In the changed subchannel number change screen 410 shown in (b), as in the subchannel number change screen 400 before change shown in (a), the physical channel number display unit 411 and the recording date and time are displayed in order from the top. A section 412, a recording time display section 413, and subchannel information display sections 414 and 415 are displayed.

  The physical channel number display unit 411, the recording month / day display unit 412 and the recording time display unit 413 include a physical channel number display unit 401, a recording month / date display unit 402 of the subchannel number change screen 400 before the change shown in FIG. Since it is the same as the recording time display unit 403, description thereof is omitted.

  The subchannel information display units 414 and 415 display the subchannel number information and the program name information changed by the subchannel change unit 113 on the recording time display unit 413 for each subchannel recorded in the program information storage unit 191. Displayed in association with the recorded recording time information. Here, the subchannel number information for the recording time between 22:00 and 23:00 is changed by the subchannel changing unit 113, and the program name information corresponding to the subchannel with the subchannel number “1” has the recording time. Between 20:00 and 22:00, it is “baseball relay”, and when the recording time is from 22:00 to 23:00, it is “baseball relay (extension)”. Also, the program name information corresponding to the subchannel with the subchannel number “2” has no data (= indicating that no broadcast is being performed) between 20:00 and 22:00, and the recording time is 22:00. It is "XX drama" between ~ 23: 00.

  In this state, when a program with a physical channel “5” and a subchannel number “1” is played, “baseball relay” is played first, and then “baseball relay (extension)” is played. Therefore, the extended program (here, the “baseball broadcast” program) can be smoothly viewed.

  FIG. 4 is a flowchart showing an example of the operation of the HDD player 1 (mainly the MPU 11). Here, for the sake of convenience, a case will be described in which the program information of one physical channel received by the reception unit 15 is stored in advance in the program information storage unit 191 by the recording execution unit 111.

  First, the playback channel setting unit 114 determines whether or not the subchannel number to be played back has been accepted (S101). If it is determined that the subchannel number has not been received (NO in S101), the process is set to a standby state. If it is determined that the subchannel number has been accepted (YES in S101), the reproduction execution unit 115 reads program information corresponding to the subchannel number accepted in step S101 from the program information storage unit 191. It is reproduced and displayed on the display 21 (S103).

  Then, the reproduction execution unit 115 determines whether or not the reproduction of the program information stored in the program information storage unit 191 has ended (S105). If it is determined that the reproduction of the program information has not ended (NO in S105), the process is set in a standby state. If it is determined that the reproduction of the program information has been completed (YES in S105), the program information corresponding to the subchannel number received in step S101 by the reproduction execution unit 115 in the program information storage unit 191 is obtained. Then, it is determined whether or not the program information whose recording is started at the same time as the recording end time of the program information that has been reproduced in step S105 is stored (S107). If it is determined that the program information is stored (YES in S107), the process returns to step S103, and the processes after step 103 are repeatedly executed. If it is determined that the program information is not stored (NO in S107), the process ends.

  In this way, the program information of one physical channel received via digital broadcasting is associated with the channel number information and program name information of each subchannel for each of a plurality of subchannels included in one physical channel. Stored in the program information storage unit 191. Then, an operation input from the user is received via the remote controller 3, and the channel number information of the subchannel stored in the program information storage unit 191 is changed based on the received operation input, and the channel number after the change is changed. Information is overwritten and recorded in the program information storage unit 191. In addition, an operation input from the user is received via the remote controller 3, and a subchannel number to be reproduced is set based on the received operation input, and program information corresponding to the set subchannel number is displayed as a program. Since it is read from the information storage unit 191 and reproduced and displayed on the display 21, the extended program can be viewed smoothly.

  That is, a program (for example, a baseball broadcast program) of one subchannel (for example, a subchannel whose channel number is “1”) included in one physical channel (for example, a physical channel whose channel number is “6”). When extended, if the broadcasting station broadcasts on another subchannel (for example, a subchannel whose channel number is “2”) included in the one physical channel, it corresponds to the extended program. The subchannel number to be played back is changed (by changing the subchannel number from “2” to “1”), and the subchannel number to be played back during playback is designated again (the subchannel number to be played back is “1”). Thus, the extended program can be viewed smoothly without changing from “2” to “2” (see FIG. 3).

  Also, a digital broadcast of one physical channel including a plurality of (for example, two) subchannels is received, and the received program information of one physical channel is converted into one physical channel based on the received information. Since each of a plurality of subchannels is recorded in the program information storage unit 191 in association with the channel number information and program name information of the subchannel, the subchannel channel number information can be received in an easy form. The program information of the one physical channel can be stored in the program information storage unit 191.

  Further, since the channel number information and program name information of the subchannel stored in the program information storage unit 191 are displayed in association with each other (see FIG. 3), the channel number information of the subchannel can be easily changed. Can be done accurately.

  That is, since the channel number information of the subchannel can be changed while checking the channel number information and the program name information displayed on the display 21, the channel number information of the subchannel can be changed easily and accurately. It can be done.

The present invention can also be applied to the following forms.
(A) In the present embodiment, the case where the digital broadcast reproduction device is the HDD player 1 has been described. However, the digital broadcast reproduction device stores program information received via digital broadcast and the stored program information. As long as it is a device that reproduces and displays it on the monitor. For example, the digital broadcast playback device may be a DVD player.

  (B) In the present embodiment, the case where the recording execution unit 111 records the program information of one physical channel received by the receiving unit 15 in the program information storage unit 191 has been described. The program information of one physical channel received by the receiving unit 15 may be stored. In this case, the apparatus is simplified.
