Record in 105 (step S22). Then, when the scheduled recording end time comes (step S23 YES), the recording of the reserved data ends, and the scheduled recording identification flag 21a is turned off (step S24).
• step S2 determines whether there is an automatic recording request (automatic recording is set to ON) (step S2 YES).
• the reservation recording request 201 In accordance with the automatic recording time setting request 203 based on the obtained automatic recording time, the automatic recording start time for starting the acquisition of the front spare data 212 and the automatic recording end time for ending the acquisition of the rear spare data 213 are calculated and reserved. Set the automatic recording time before and after (Step S3).
• step S4 When the automatic recording start time comes (step S4 YES), the recording of the forward spare data 212 is started (see Fig. 2), and the content data is added with an automatic recording identification flag 21b, and the forward spare data 212 is added. Record 212 in the node disk drive (HDD) 105 (step S5).
• step S6 After that, when the reservation recording start time comes (step S6 YES), the recording is switched from automatic recording to reservation recording, data recording is continued, the reservation data identification flag 2 la is added to the content data, and the data according to the reservation is loaded. The data is recorded on the disk drive (HDD) 105 (step S7).
• step S8 YES when the reservation end time comes (step S8 YES), the recording is switched from the reservation recording to the automatic recording to continue the data recording, and the recording of the rear spare data 213 is started by attaching the automatic recording identification flag 2lc to the content data. (Step S9).
• step S10 YES When the automatic recording end time comes (step S10 YES), the recording of the rear preliminary data 213 ends (step S11).
• the program recording data RD including the front spare data 212 and the rear spare data 213 in the reservation recording data 211 includes Be recorded.
• the user can use the "VIDEO" button b4, "PLAY ) Button b31 or the like to give an instruction to play back the recorded data
• the CPU 101 reads the program recording data RD according to the playback request from the hard disk drive (HDD) 105 in response to the playback request, and
• the recording data RD is transmitted to the TV device via the MPEG decoder 113, the graphics unit 115, and the video output terminal 119.
• the audio data is also transmitted to the TV device via the MPEG decoder 113, the audio DZA converter 114, and the audio output terminal 118.
• the CPU 101 At the time of outputting (reproducing and outputting) the program recording data RD, the CPU 101 The contents of the identification flags (21a, 21b, 21c) attached to the reserved recording data 211 with the reserved recording identification flag 21a, the preliminary backup data 212 with the automatic recording identification flags 21b, 21c, and the It discriminates it from the rear spare data 213, removes the front spare data 212 and the rear spare data 213 from the output target power, and sends the reservation recording data 211 to the MPEG decoder 113 as the output target. Therefore, in the normal use state, the reservation recording data 211 according to the reservation is reproduced and output on time.
• the user is provided with the recording data (preliminary preliminary data 212 and backward preliminary data 213) in the time zone before and after the reserved recording data 211.
• the data extraction of the front preliminary data 212 and the rear preliminary data 213 is realized by extracting the content data having the automatic recording identification flags 21b and 21c and sending the extracted data to the MPEG decoder 113.
• the CPU 101 When receiving a request to delete recorded data by designating a recorded program from the user, the CPU 101 deletes the recorded data according to the request from the node disk drive (HDD) 105. At this time, the CPU 101 also adds the designated reserved recording data 211 based on the automatic recording identification flags 21b and 21c, and the preceding and following spare data 212 and backward spare data 213, that is, the program recording data. Erase the entire RD.
• the present invention is not limited to erasing the entire program recording data RD as described above, but leaves only reserved recording data 211 which is short and only forward spare data 212 and backward spare data 213 before and after it. , Or only one of the forward spare data 212 and the backward spare data 213 can be erased.
• the forward spare data 212, the reservation record data The data 211 and the rear spare data 213 are treated as program recording data RD without being individually distinguished, and the program recording data RD is targeted for partial deletion.
• the recording time intended by the user and the recording time intended by the user can be changed due to a time lag of the clock incorporated in the device, a change in the broadcast time and the like.
• the contents are misaligned, the information of the part missing due to the misalignment can be easily obtained and reproduced.
• the recorded program recording data RD capability is also limited because unnecessary portions can be arbitrarily erased, and only the necessary portions can be recorded in the data recording unit 13.
• the capacity of the data recording unit 13 can be effectively used.
