  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of an information recording / reproducing apparatus (program reproducing apparatus) according to an embodiment of the present invention.

  The recording / reproducing apparatus of FIG. 1 includes a microcomputer block 30, an encoder unit 50, and a decoder unit 60.

  The microcomputer block 30 has an MPU (micro processing unit) or a CPU (central processing unit) (not shown), and controls the operation of each block of the recording / reproducing apparatus. The microcomputer block 30 includes a ROM in which a control program is written, a RAM for providing a work area necessary for program execution, and the like.

  The microcomputer block 30 includes a reproduction control unit 311, a recording control unit 312, and a scheduled recording control unit 313. The reproduction control unit 311 controls the reproduction processing of the received broadcast program data and the program data stored in the storage medium. The recording control unit 312 controls recording processing of program data on a storage medium. The reserved recording control unit 313 controls the reserved recording process of the program. The microcomputer block 30 also includes a program information management unit 321, a recorded program information management unit 322, a recording history management unit 323, a related program detection unit 324, an operation support screen generation unit 325, and a screen display control unit 326, which will be described later. Yes. The microcomputer block 30 can also be connected to an external network via the network interface 30a.

  An operation signal for operating the storage / reproduction device is input to the microcomputer block 30 from the key operation input unit 44. The key operation input unit 44 is, for example, operation switches provided on the main body of the recording / reproducing apparatus or a remote controller. A personal computer connected to the recording / reproducing apparatus by wired communication, wireless communication, optical communication, infrared communication, or the like may be employed as the key operation input unit 44. The key operation input unit 44 includes various operation keys such as a determination key, a stop key, an end key, and a cursor key. The user operates the key operation input unit 44 to record the received or input video signal or audio signal, to reproduce the content stored in the storage medium, or to edit the content stored in the storage medium. Can be instructed.

  Among the execution results of the MPU (or CPU) of the microcomputer block 30, the contents to be notified to the user are displayed on the display unit 43 or displayed on the monitor display 3001 as OSD (on-screen display).

  The information storage / reproduction apparatus shown in FIG. 1 has a DVD-RAM, DVD ± RW, DVD ± R, DVD-ROM (DVD video), CD-RW, CD-R, CD-ROM (storage medium) as a storage medium (information storage medium). Both music discs and other optical disks and hard disks can be handled. These hard disks and optical disks may be replaced (or used together) with other storage media such as a semiconductor memory.

  This recording / reproducing apparatus has two types of disk drive units, an optical disk drive unit 1002 and a hard disk drive unit 2001. The optical disc drive unit 1002 includes a rotation control system, a laser drive system, an optical system, and the like for the optical disc 1001, and drives the optical disc 1001 to read and write information. The hard disk drive unit 2001 drives a hard disk to read / write information.

  The data processor unit 1003 includes a buffer circuit, a modulation / demodulation circuit, an error correction unit, and the like, and handles data in a predetermined recording unit or reproduction unit. The data processor unit 1003 supplies recording data to the optical disc drive unit 1002 and the hard disk drive unit 2001. Further, the data processor unit 1003 receives the reproduction data read by the optical disk drive unit 1002 and the hard disk drive unit 2001.

  The data processor unit 1003 instructs the microcomputer block 30 to perform an editing process such as deleting a part of video objects constituting program data stored in the storage medium or connecting video objects of a plurality of different programs. It can also be done according to.

  The encoder unit 50 receives an external analog video signal and an external analog audio signal from the AV input unit 41a, or a broadcast reception signal (from a terrestrial analog tuner 41b, a terrestrial digital tuner 41c, a satellite digital tuner 41d, or a satellite analog tuner 41e). One or more) selectively input. The switch (signal selector) 53 switches the signal system to be input to the encoder unit 50 under the control of the microcomputer block 30.

  The encoder unit 50 includes a video and audio analog-to-digital converter that digitizes an input analog video signal or analog audio signal, a video encoder, and an audio encoder. Furthermore, a sub-picture encoder that represents subtitles and pictures as bitmap data can be included as appropriate.

  The encoder unit 50 includes a transport stream processing unit and a plurality of MPEG encoders. An MPEG video encoder included in the encoder unit 50 compresses an input digital video signal at a variable bit rate based on the MPEG2 or MPEG1 standard, and converts it into a digital video signal that can be recorded on a hard disk or an optical disk. The digital audio signal is converted into a digital audio signal compressed at a fixed bit rate based on the MPEG or AC-3 standard, or an uncompressed linear PCM digital audio signal.

  When the sub video signal is input to the encoder unit 50 from the AV input unit 41a (for example, a signal input from a DVD video player with an independent output terminal of the sub video signal), or a DVD video signal including the sub video signal is When the terrestrial analog tuner 41b, the terrestrial digital tuner 41c, the satellite digital tuner 41d, or the satellite analog tuner 41e is input to the encoder unit 50, the sub video signal input to the encoder unit 50 is encoded by the sub video encoder ( Sub-picture bitmap data is obtained by run-length encoding based on the DVD standard.

  The formatter 51 converts the encoded digital video signal, digital audio signal, and sub-picture data into a predetermined format using the buffer memory 52 as a work memory. That is, the formatter 51 packs the encoded digital video signal, digital audio signal, and sub-picture data into a video pack, an audio pack, and a sub-picture pack, and further collects them to define the DVD video standard. The format (DVD-Video format) or the format (DVD-VR format) defined by the DVD-recording standard is converted. However, when a digital broadcast transport stream (MPEG2-TS) is recorded as a stream, format conversion is not necessary.

  When a compressed (encoded) digital video signal or digital audio signal is directly input to the encoder unit 50, the input signal can be directly supplied to the formatter 51 without performing an encoding process. The encoder unit 50 can also directly supply the digital video signal and digital audio signal that have been digitally converted to the video mixing unit 71 and the audio selector 76.

  Information (packet of video, audio, sub-picture data, etc.) converted in format by the formatter 51 is supplied to the hard disk drive unit 2001 and / or the optical disk drive unit 1002 via the data processor unit 1003, and the hard disk, the optical disk 1001, etc. Recorded on a storage medium. In addition, information recorded on the hard disk or the optical disk 1001 can be recorded on the optical disk 1001 or the hard disk via the data processor unit 1003 and the optical disk drive unit 1002.

  When recording information on the storage medium, the formatter 51 creates segmentation information and periodically sends it to the MPU of the microcomputer block 30 (information at the time of GOP head interrupt, etc.). The segmentation information includes the number of VOBU packs, the end address of the I picture from the beginning of the VOBU, the playback time of the VOBU, and the like.

  When information is recorded on the storage medium, the MPU of the microcomputer block 30 creates management information necessary for reproducing the recorded information. When the MPU recognizes the recording end command, the MPU sends the created management information to the data processor unit 1003. Thereby, the management information is recorded on the storage medium.

  In order to reproduce a recorded program stored in a storage medium without interruption, a minimum continuous information unit (size) of recorded program data to be accessed (seeked) by the data processor unit 1003 is determined in advance. This information unit storage area is called a CDA (Contiguous Data Area). The CDA size is a multiple of an ECC (error correction code) block (16 sectors), and data is stored in units of CDA. The data processor unit 1003 receives VOBU unit data from the encoder unit 50 and supplies the CDA unit data to the optical disk drive unit 1002 or the hard disk drive unit 2001.

  When the encoder unit 50 includes, for example, two MPEG encoders, the encoder unit 50 can encode two signals. For example, the program received by the terrestrial analog tuner 41b can be DVD-VR recorded by the hard disk drive unit 2001, and at the same time, the program received by the satellite analog tuner 41e can be DVD-VR recorded by the optical disc 1001.

  Further, the packet elementary stream extracted from the transport stream may be recorded directly on the hard disk of the hard disk drive unit 2001 from the encoder unit 50. Even when the encoder section 50 has only one MPEG encoder, the hard disk drive section 2001 records the program data (MPEG2-TS) input to the encoder section 50 via the terrestrial digital tuner 41c or the satellite digital tuner 41d. At the same time, broadcast program data input through another tuner can be encoded by this single MPEG encoder.

  The decoder unit 60 includes a separator, a video decoder, a sub-picture decoder, an audio decoder, and a video processor (not shown). The separator separates each pack from a DVD format signal having a pack structure. The video decoder performs a decoding process on the main video data (video pack contents) separated by the separator. The sub-picture decoder decodes sub-picture data (sub-picture pack contents) separated by the separator. The audio data (the contents of the audio pack) separated by the separator is decoded by the audio decoder. The video processor appropriately synthesizes the decoded sub-video with the decoded main video, and superimposes the menu, highlight button, subtitles, and other sub-videos on the main video and outputs them. The decoder unit 60 further includes a memory used when performing pack separation and other signal processing.

  The video signal output from the decoder unit 60 is input to the video mixing unit 71. The video mixing unit 71 synthesizes text data, for example. The video mixing unit 71 is also connected to a line for directly receiving signals from the AV input unit 41a, the terrestrial analog tuner 41b, the terrestrial digital tuner 41c, the satellite digital tuner 41d, and the satellite analog tuner 41e. A frame memory 72 used as a buffer is connected to the video mixing unit 71. A video signal output from the video mixing unit 71 is output to the outside via an I / F (interface) 73. Alternatively, the video signal output from the video mixing unit 71 is analog-converted by the digital-analog converter 74 and output to the monitor display 3001.

  The audio signal output from the decoder unit 60 is input to the digital / analog converter 77 via the selector 76. The digital / analog converter 77 converts the digital audio signal into an analog signal and outputs it to the outside (for example, a speaker). The selector 76 is controlled by a select signal from the microcomputer block 30. When directly monitoring digital signals from the tuners 41b to 41e and the AV input unit 41a, it is also possible to directly select a signal that has passed through the encoder unit 50. is there.

  The microcomputer block 30 controls the optical disk drive unit 1002, the hard disk drive unit 2001, the data processor unit 1003, the encoder unit 50, the decoder unit 60, and the like based on time data from an STC (system time clock) 38. Recording and playback operations are normally executed in synchronization with the time clock from the STC 38, but other processes may be executed at a timing independent of the STC 38.

  The microcomputer block 30 uses an electronic program service for terrestrial analog broadcasting (ADAMS: TV-Asahi Data and Multimedia Service in Tokyo area) or an electronic guide information / electronic program guide (EPG) service for terrestrial / satellite digital broadcasting. Thus, electronic program guide information (including not only broadcast programs but also various information services) can be acquired periodically, for example, every hour. It is also possible to fetch electronic program guide information (DEPG) from an external server 210 via the network 200.

  The acquired electronic program guide information is managed by the program information management unit 321. The program information management unit 321 manages the electronic program guide information by providing a program information management table as shown in FIG. 2 in the ROM of the microcomputer block 30. In the example of FIG. 2, data such as “channel”, “broadcast date”, “broadcast start time”, “program length”, and “program name” are stored for each broadcast program. Further, a “reserved” attribute is given to a program for which a user has made a recording reservation. The program information management unit 321 also includes information indicating the relevance such as “series name” for related programs such as a series of programs broadcast at a fixed time every day or a fixed time every day of the week. to manage. The same series name is assigned to programs belonging to the same series even if the broadcast day of the week or the broadcast time is different. The program information management unit 321 normally manages electronic program guide information for a predetermined period (for example, one week). The program name consists of a series name, a broadcast time, a subtitle (rebroadcast), and the like.

  FIG. 3 is a diagram showing an example of a program guide based on the program guide information stored in the program information management table of FIG. The program table in FIG. 3 shows the broadcast schedule for one week from “10/15 (Sunday)” in the time zone “20:00 to 24:00” in the channel (broadcasting station) “Buji TV”. Yes.

  Information of a program (program content) stored in a storage medium such as a hard disk or an optical disk is managed by a recorded program information management unit 322. The recorded program information management unit 322 manages recorded program information by providing a recorded program information table as shown in FIG. 4 in the ROM of the microcomputer block 30. In the example of FIG. 4, “program name”, “recording quality”, “recording length”, “channel”, “recording date”, “recording start time”, “viewing information”, “series name”, “series name”, “ Data such as “folder name” is stored. The “folder name” data represents in which folder the recorded program is stored. FIG. 4 is a recorded program information table for managing recorded program information stored in the hard disk. A recorded program information table may be provided for each storage medium, and recorded program information may be managed for each storage medium, but recorded program information stored in a plurality of storage media is stored in one recorded program information table, You may make it manage collectively.

  The recording history management unit 323 manages the history of broadcast program recording processing performed by the recording control unit 312. The recording history management unit 323 manages a recording process history information by providing a recording history table as shown in FIG. 5 in the ROM of the microcomputer block 30, for example. In the recording history table, information on broadcast programs that have been recorded by the recording control unit 312 is stored. In the example of FIG. 5, data such as “program name”, “channel”, “broadcast date”, “broadcast start time”, “viewing information”, “deletion information”, “series name”, etc. of the recorded broadcast program is recorded. Remembered. “Delete information” data represents whether or not the broadcast program has already been deleted from the storage medium. In addition to the above data, the recording history table stores data such as “recording quality”, “recording length”, “recording destination storage medium name”, and “recording destination folder name” of the broadcast program. Also good.

  Broadcast program information that has already been deleted from the storage medium is deleted from the above-mentioned recorded program information table, but is not deleted from this recorded history table. Further, program information stored in the storage medium by a method other than broadcast reception (for example, copying from another storage medium) may be stored in the recording history table, but stored in the recording history table. Instead, it may be stored only in the recorded program information table.

  When the reproduction processing of the recorded program recorded in the storage medium such as a hard disk is stopped, the related program detection unit 324 relates to the processing target program based on the series name of the program (processing target program) for which the reproduction is stopped. The program information to be detected is detected from the program information management table (see FIG. 2) and the recorded program information table (see FIG. 4).

  Based on the related program information detected by the related program detection unit 324, the operation support screen generation unit 325 generates screen data of the menu screen D for supporting the user's next operation.

  The screen display control unit 326 displays the menu screen D generated by the operation support screen generation unit 325 on the monitor display 3001 (see FIG. 6). The menu screen D includes menu items such as “reproduce next program”, “reservation recording of related program”, “jump to program guide”, and “process target program to trash folder”.

  For example, when playback of a recorded program (program to be processed) called “Minami 10 Onna # 2” broadcast from “10/3 (Wednesday) 22:00” on the channel “Buji TV” stops, the related program The detection unit 324 detects a program with the same series name (Woman 10 Woman # 2) as “Water 10 Woman # 2”. From the recorded program information table (see FIG. 4), a program (“Mizu 10 Onna # 3” in the same series) related to “Mizu 10 Onna # 2” already recorded on the storage medium is detected. From the information management table (see FIG. 2), a program scheduled to be broadcast related to “Water 10 Onna # 2” (“Water 10 Onna # 1 (Rebroadcast)”, “Water 10 Onna # 4 ”and“ Ona # 5 on water 10 ”) are detected.

  The operation support screen generation unit 325 generates menu screen data based on the detection result by the related program detection unit 324. In other words, the operation support screen generation unit 325 uses the menu word “play“ Minami 10 Onna # 3 ”” as the “play next program” item described above, and “ The menu wording “Reserve 10 # 4” is set to “Jump to Program Guide” and the word “Jump to 10 # 4” on “Buji TV Wednesday 21:00” Menu screen data including a menu word ““ Wanna 10 on water # 2 ”to trash” is generated as an item of “To trash folder”.

  Here, the menu wording of the item “next program playback” includes the program name of the related program detected from the recorded program information table (see FIG. 4). When the related program detection unit 324 detects a plurality of related programs from the recorded program information management table, a predetermined selection rule (for example, a program of broadcast times after the processing target program is selected in order of broadcast times) Alternatively, the program name of one related program selected according to a preferential selection from unviewed recorded programs, etc.) is taken into the menu wording.

  In addition, the menu wording of the “jump to program guide” item includes the program name of the related program detected from the program information management table (see FIG. 2). When the related program detection unit 324 detects a plurality of related programs from the program information table, a predetermined selection rule (for example, an unrecorded broadcast program is selected in the order of broadcast times, or the recording time of the processing target program is recorded. The program name of one related program selected in accordance with the preferential selection of related programs scheduled to be broadcast in a time zone close to is incorporated into the menu wording.

  Here, for example, in the case of the above-mentioned “Mizu 10 Onna” series program, the broadcast times are designated by numbers after “#” included in the program name. Not limited.

  The screen display control unit 326 displays a menu screen D as shown in FIG. 6 on the monitor display 3001 based on the menu screen data generated by the operation support screen generation unit 325. When the menu screen D is initially displayed, predetermined items may be highlighted. In the example of FIG. 6, the “related program recording reservation” item is highlighted.

  The menu wording of the “related program recording reservation” item includes the program name of the related program detected from the program information management table (see FIG. 2). This related program (reservation candidate program) is selected from the same channel as the processing target program whose reproduction has been stopped.

  As a rule for selecting a program that is a candidate for reservation from related programs detected by the related program detection unit 324 from the program information management table, the following rules can be considered.

(A) Of the programs whose broadcast times are after the program to be processed, the programs whose broadcast times are close to the program to be processed are set as reservation candidate programs.

(B) A program scheduled to be broadcast in the same time zone as the program to be processed is set as a reservation candidate program.

(C) The program with the earliest broadcast schedule is set as a reservation candidate program.

  When the selection rule (a) is adopted, the following cases can be considered.

(A-1) The program stored in the storage medium is excluded from the reservation candidates.

(A-2) Programs with a recording history are excluded from reservation candidates.

  The operation support screen generation unit 325 uses any of these selection rules to select a reservation candidate program, and incorporates the program name of the selected reservation candidate program into the menu wording of the “reserved program recording reservation” item. . Which selection rule the operation support screen generation unit 325 uses may be set in advance or may be selected by the user. Or you may determine according to a user's operation tendency.

  Next, processing for selecting a program that is a candidate for reservation from related programs detected by the related program detection unit 324 from the program information management table will be described.

In the case of (a-1) FIG. 7 is a flowchart of a process of selecting a reservation candidate program from programs that are broadcast times after the processing target program and are close to the processing target program except for the recorded program. .

  When the reproduction of the recorded program is stopped and the reservation candidate selection process is started, the related program detection unit 324 records information such as “channel” and “series name” of the program (processing target program) whose reproduction has been stopped. Obtained from the information table (see FIG. 4) (block A11).

  Subsequently, the related program detection unit 324 detects a recorded program having the same series name as the acquired processing target program from the recorded program information table, and generates a list (holding list) L1 of the detected recorded programs (block A12). .

  FIG. 8 is a diagram illustrating an example of the holding list L1. The holding list L1 in FIG. 8 shows a list of programs having the same series name (Wanna 10 Onna) as the processing target program “Mizu 10 Onna # 2” detected from the recorded program information table of FIG.

  Next, the related program detection unit 324 detects a program (related program) having the same channel name and series name as the processing target program from the program information management table (block A13). For example, from the program information management table shown in FIG. 2, a broadcast scheduled program “Minami 10 Onna # 1 (Rebroadcast)” having the same series name as the processing target program “Mizu 10 Onna # 2”. , “Water # 10 # 4” and “Water 10 # 5” are detected.

  Subsequently, the related program detection unit 324 determines whether there is a program whose program name is not included in the holding list L1 among the related programs detected from the program information management table (block A14). If a program that is not included in the holding list L1 is detected (YES in block A14), the program that is not included in the holding list L1 and is the youngest among the programs that are broadcast after the processing target program. Broadcast times (close to the program to be processed) are reserved candidates (block A15).

  On the other hand, if all the programs detected from the program information management table are included in the holding list L1 (NO in block A14), no reservation candidate program is set (block A16), and the process ends. .

  When a reservation candidate program is selected, the operation support screen generation unit 325 generates menu screen data having the menu wording of the “related program recording reservation” item including the program name of the reservation candidate program. The screen display control unit 326 displays the menu screen D on the monitor display 3001 based on the menu screen data generated by the operation support screen generation unit 325. When no reservation candidate program is selected, the menu item “Reservation of recording of related program” is not displayed.

  In the example described above, “Water 10 Onna # 1 (Rebroadcast)”, “Water 10 Onna # 4”, and “Water 10 Onna # 5” detected from the program information management table in block A13 are shown in FIG. 8 is not included in the holding list L1. In block A14, among these detected programs, “Mizu 10 Onna # 4” of the broadcasting times closest to the processing target program after the processing target program “Mizu 10 Onna # 2” is selected as a reservation candidate. . Therefore, the menu item “Reserve“ # 4 of water 10 ”” is displayed on the monitor display 3001 as shown in FIG.

  For this reason, it is possible to avoid presenting a reservation operation for a program already stored in the storage medium to the user, and to present only an unrecorded program to the user as a reservation candidate.

In the case of (a-2) FIG. 9 shows a process of selecting a reservation candidate program from a program of broadcast times that is close to the process target program, except for programs with a recording history. It is a flowchart.

  When the reproduction of the recorded program is stopped and the reservation candidate selection process is started, the related program detection unit 324 records information such as “channel” and “series name” of the program (processing target program) whose reproduction has been stopped. Obtained from the information table (see FIG. 4) (block A21).

  Subsequently, the related program detecting unit 324 detects a recorded program having the same series name as the acquired program to be processed from the recording history table (see FIG. 5), and a list of programs having the detected recording history (recording history list). L2 is generated (block A22).

  FIG. 10 is a diagram illustrating an example of the recording history list L2. The recording history list L2 in FIG. 10 is a list of programs having the same series name (Wanna 10 Onna) as the processing target program “Mizu 10 Onna # 2” detected from the recording history table in FIG.

  Next, the related program detection unit 324 detects a program (related program) having the same channel name and series name as the processing target program from the program information management table (block A23). For example, from the program information management table shown in FIG. 2, a broadcast scheduled program “Minami 10 Onna # 1 (Rebroadcast)” having the same series name as the processing target program “Mizu 10 Onna # 2”. , “Water # 10 # 4” and “Water 10 # 5” are detected.

  Subsequently, the related program detection unit 324 determines whether there is a program whose program name is not included in the recording history list L2 among the related programs detected from the program information management table (block A24). If a program that is not included in the recording history list L2 is detected (YES in block A24), among the programs that are not included in the recording history list L2 and are broadcast after the processing target program, The youngest broadcast time (close to the program to be processed) is a reservation candidate (block A25).

  On the other hand, if all the programs detected from the program information management table are included in the recording history list L2 (NO in block A24), no reservation candidate program is set (block A26), and the process ends. To do.

  When a reservation candidate program is selected, the operation support screen generation unit 325 generates menu screen data having the menu wording of the “related program recording reservation” item including the program name of the reservation candidate program. The screen display control unit 326 displays the menu screen D on the monitor display 3001 based on the menu screen data generated by the operation support screen generation unit 325. When no reservation candidate program is selected, the menu item “Reservation of recording of related program” is not displayed.

  In the above-described example, “water 10 rice # 4” and “water 10 rice # 5” detected from the program information management table in block A23 are not included in the recording history list L2 of FIG. In block A24, among these detected programs, “Mizu 10 Onna # 4” of the broadcasting times closest to the processing target program after the processing target program “Mizu 10 Onna # 2” is selected as a reservation candidate. . Accordingly, “Reserve“ # 4 of water 10 ”” is displayed on the monitor display 3001 as shown in FIG.

  For this reason, it is avoided to present to the user a reservation operation for a program that has already been stored in the storage medium, and only a program without a recording history can be presented to the user as a reservation candidate.

In the case of (b) FIG. 11 is a flowchart of processing for selecting a program scheduled to be broadcast in the same time zone as the processing target program as a reservation candidate.

  When the reproduction of the recorded program is stopped and the reservation candidate selection process is started, the related program detecting unit 324 displays the “channel”, “start time”, “series name”, etc. of the program (processing target program) whose reproduction has been stopped. Is acquired from the recorded program information table (see FIG. 4) (block B1).

  Next, the related program detecting unit 324 detects a program (related program) having the same channel name and series name as the processing target program from the program information management table (block B2). For example, from the program information management table shown in FIG. 2, a broadcast scheduled program “Minami 10 Onna # 1 (Rebroadcast)” having the same series name as the processing target program “Mizu 10 Onna # 2”. , “Water # 10 # 4” and “Water 10 # 5” are detected.

  Subsequently, the related program detection unit 324 determines whether a program broadcast in the same time zone as the processing target program is detected among the related programs detected from the program information management table (block B3). If a program broadcast in the same time zone is detected (YES in block B3), the program scheduled to be broadcast the earliest among the programs broadcast in the same time zone is selected as the reservation candidate program. (Block B4).

  On the other hand, if the start of broadcasting of all the programs detected from the program information management table is scheduled in a time zone different from the processing target program (NO in block B3), no reservation candidate program is set (block B5). , The process ends.

  When a reservation candidate program is selected, the operation support screen generation unit 325 generates menu screen data having the menu wording of the “related program recording reservation” item including the program name of the reservation candidate program. The screen display control unit 326 displays the menu screen D on the monitor display 3001 based on the menu screen data generated by the operation support screen generation unit 325. When no reservation candidate program is selected, the menu item “Reservation of recording of related program” is not displayed.

  In the above-described example, among “Water 10 Onna # 1 (Rebroadcast)”, “Water 10 Onna # 4”, and “Water 10 Onna # 5” detected from the program information management table in block B2, The same time zone (22:00:00 to 23:00) “Mizu 10 Onna # 5” as the processing target program “Mizu 10 Onna # 2” is selected as a reservation candidate. Accordingly, the menu word “Reserve“ # 10 on Water 10 ”” is displayed on the monitor display 3001 as the menu item “Reservation recording of related program”.

  Even when a program is organized so that rebroadcasts of the same program series are repeated many times within a predetermined period, the continuity of the broadcast times is often maintained for each broadcast time period. Therefore, by presenting only programs in the same broadcast time period to the user as reservation candidates, it is possible to ensure the certainty of the series.

  Moreover, in the above-mentioned example, although 1 hour is made into the unit of a time slot | zone, the method of setting a time slot | zone is not restricted to this.

In the case of (c) FIG. 12 is a flowchart of processing for selecting a program with the earliest broadcast schedule as a reservation candidate.

  When the reproduction of the recorded program is stopped and the reservation candidate selection process is started, the related program detection unit 324 records information such as “channel” and “series name” of the program (processing target program) whose reproduction has been stopped. Obtained from the information table (see FIG. 4) (block C1).

  Next, the related program detecting unit 324 detects a program (related program) having the same channel name and series name as the processing target program from the program information management table (block C2). For example, from the program information management table shown in FIG. 2, a broadcast scheduled program “Minami 10 Onna # 1 (Rebroadcast)” having the same series name as the processing target program “Mizu 10 Onna # 2”. , “Water # 10 # 4” and “Water 10 # 5” are detected.

  When the related program detection unit 324 detects a related program from the program information management table (YES in block C3), the program scheduled to be broadcast earliest is selected as the reserved candidate program (block C4). ).

  On the other hand, when the related program is not detected from the program information management table (NO in block C3), no reservation candidate program is set (block C5), and the process ends.

  When a reservation candidate program is selected, the operation support screen generation unit 325 generates menu screen data having the menu wording of the “related program recording reservation” item including the program name of the reservation candidate program. The screen display control unit 326 displays the menu screen D on the monitor display 3001 based on the menu screen data generated by the operation support screen generation unit 325. When no reservation candidate program is selected, the menu item “Reservation of recording of related program” is not displayed.

  In the above-described example, among “Water 10 Onna # 1 (Rebroadcast)”, “Water 10 Onna # 4”, and “Water 10 Onna # 5” detected from the program information management table in block C2, “Wanna 10 Onna # 1” broadcasted earliest is selected as a reservation candidate. For this reason, on the monitor display 3001, as a menu item of “Reserving recording of related program”, a menu word “Reserving“ # 1 ”on Wednesday 10” is displayed.

  Therefore, for example, as shown in the recording history table of FIG. 5, a rebroadcast of “Woman 10 Onna # 1” is scheduled for a user who has deleted “Water 10 Ona # 1” once recorded. You can notice that. Or, even if the user has failed to record “Water 10 Onna # 1” that was broadcast earlier for some reason, the re-broadcast of “Water 10 Onna # 1” is scheduled. Users can be made aware.

  As described above, a reservation candidate is selected by the reservation candidate selection process according to the flowchart of FIG. 7, FIG. 9, FIG. 11, or FIG. 12, and the menu screen D corresponding to this selection is displayed on the monitor display 3001. The Which reservation candidate selection process the operation support screen generation unit 325 uses may be set in advance or may be selected by the user. Or you may determine according to a user's operation tendency.

  When the menu screen D is displayed on the monitor display 3001, the user can select any menu item included in the menu screen D by operating the key operation input unit 44.

  Next, the operation of the recording / reproducing apparatus performed when the user selects any menu item will be described.

  When the user selects the “play next program” item (in the example of FIG. 6, “play“ # 3 ”on water 10”), the playback control unit 311 performs playback processing of the selected program. . If the menu item “Jump to Program Guide” (in the example of FIG. 6 “Jump to Buzzi TV Wednesday 21:00 Wednesday 10 Female # 4”) is selected, the selected program is displayed. The included electronic program guide is displayed on the monitor display 3001. When the item “process target program to trash folder” is selected (in the example of FIG. 6, “Wonder 10 # 2” is trashed ”), the recording control unit 312 displays the program that has been stopped. Are moved to a predetermined trash folder.

  In addition, when the user selects the menu item “Reserving recording of related program” (“Reserving“ # 4 ”on water 10” in the example of FIG. 6), the reserved recording control unit 313 is selected. Program recording reservation processing is performed.

  FIG. 13 is a flowchart of the scheduled recording setting process performed by the scheduled recording control unit 313.

  When the user selects the menu item “Reserved recording of related program” and the reserved recording setting process is started, the reserved recording control unit 313 selects a recorded program (processing target program) whose reproduction is stopped from the recorded program information table. “Recording quality” data is acquired (block D1). Next, the scheduled recording control unit 313 also acquires “folder name” data of the folder in which the processing target program is stored from the recorded program information table (block D2). The timer recording control unit 313 sets the acquired data as the timer recording setting value of the selected related program (block D3).

  The screen display control unit 326 causes the monitor display 3001 to display a reservation registration screen based on the setting by the reservation recording setting process.

  FIG. 14 is a diagram illustrating an example of a reservation registration screen. In the example of FIG. 14, when “Reserve“ # 10 ”on water 10” is selected from the menu screen D of FIG. 6, and a recording reservation for “Onna # 4 of water 10” is instructed, the monitor display 3001. The reservation registration screen displayed on is shown.

  As shown in FIG. 14, the recording quality setting “SP mode” of the processing target program “Water 10 Onna # 2” acquired in block D1 as the recording quality setting of “Water 10 Onna # 4” is “Water Mode 10 # 4”. As the recording destination folder setting of “1 woman # 4”, the recording folder “use of water 10” for “water 10 girl # 2” acquired in block D2 is taken over.

  The user can make a recording reservation for a reservation candidate program with the same setting as the processing target program by simply pressing the “execute registration” button at the lower right of the screen. For this reason, the user does not have to perform complicated setting operations for reserving and recording related programs.

  As described above, according to the present embodiment, when playback of the recorded program (processing target program) stored in the storage medium is stopped, the menu screen D as shown in FIG. 6 is displayed on the monitor display 3001. . Among the menu items included in the menu screen D, the menu word corresponding to the item “Reservation recording of related program” includes the program name selected as the reservation candidate program among the related programs detected from the program information management table. Is adopted. At this time, the following rules can be considered as a rule for selecting a program as a reservation candidate.

(A) Of the programs whose broadcast times are after the program to be processed, the programs whose broadcast times are close to the program to be processed are set as reservation candidate programs.

    (A-1) The program stored in the storage medium is excluded from the reservation candidates.

    (A-2) Programs with a recording history are excluded from reservation candidates.

(B) A program scheduled to be broadcast in the same time zone as the program to be processed is set as a reservation candidate program.

(C) The program with the earliest broadcast schedule is set as a reservation candidate program.

  Which selection rule is used may be determined in advance or may be selected by the user. Or you may determine according to a user's operation tendency.

  By displaying the menu screen D, it is possible to present a recording reservation operation for a related program suitable for the user.

  Further, when the user selects the menu item “Reservation recording of related program” described above on the menu screen D, the reservation recording process of FIG. 13 is performed, and the recording setting of the processing target program is selected as the reservation candidate. You can take over the recording settings.

  In the above description, a program having the same series name is a related program. However, the relevance may be determined by an attribute other than the series name. For example, when information such as “genre” and “performer” for each program is stored in the program information management table managed by the program information management unit 321, the “genre” and “performer” information is stored. The relevance may be determined based on the above.
