  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

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

  The information recording / reproducing apparatus shown in FIG. 1 can record a program on both the optical disk 10 such as a DVD and the hard disk unit 14. In addition, this information recording / reproducing apparatus can also be provided with, for example, a semiconductor memory as a program recording destination.

  In FIG. 1, the main block of the recording unit is shown on the left side, and the main block of the playback unit is shown on the right side. The information recording / reproducing apparatus includes two types of disk drive units, a disk drive unit 12 and a hard disk drive unit 14. The disk drive unit 12 rotationally drives the optical disk 10 to read / write information. The disk drive unit 12 includes a rotation control system, a laser drive system, an optical system, and the like for the optical disk 10. The hard disk drive unit 14 drives the hard disk and executes reading and writing of information.

  The information recording / reproducing apparatus also includes a data processor unit 16. The data processor unit 16 supplies recording data to the disk drive unit 12 and the hard disk drive unit 14, and the disk drive unit 12 and the hard disk drive unit 14 The read reproduction data is received. The data processor unit 16 processes recording data or reproduction data of a predetermined unit, and includes a buffer circuit, a modulation / demodulation circuit, an error correction circuit, and the like.

  The information recording / reproducing apparatus includes an encoder unit 30, a decoder unit 50, and a microcomputer block 70. An external analog video signal and an external analog audio signal from the AV input unit 18a are input to the encoder unit 30 via the switch 20. Also, the encoder unit 30 is selectively input with received signals from the terrestrial analog tuner 18b, the terrestrial digital tuner 18c, the satellite BS / CS tuner 18d, and the satellite analog tuner 18e via the switch 20. For example, this information recording / reproducing apparatus can record the program received by the terrestrial digital tuner 18c by the hard disk drive unit 14 and simultaneously reproduce the program received by the satellite BS / CS tuner 18d by the decoder 50.

  The encoder unit 30 includes a transport stream processing unit and a plurality of encoders, and each encoder includes an analog-digital converter, a video encoder (a main video encoder and a sub video encoder), and an audio encoder. The analog-digital converter digitizes an input analog video signal or analog audio signal. The main video encoder encodes the main video signal of the digital video signal, the audio encoder encodes the digital audio signal, and the sub video encoder encodes the sub video signal of the digital video signal. More specifically, the video encoder compresses the digital video signal at a variable bit rate based on the MPEG2 or MPEG1 standard. The audio encoder compresses a digital audio signal at a fixed bit rate based on the MPEG or AC-3 standard.

  When a sub video signal (for example, a signal from a DVD video player with an independent output terminal of a sub video signal) is input to the encoder unit 30 from the AV input unit 18a, or a DVD video signal including a sub video signal is received. When received by the TV tuner unit, the sub-picture signal in the DVD video signal is encoded (run-length encoded) by the sub-picture encoder to become a sub-picture bitmap.

  The encode output signal from the encoder unit 30 is converted into a predetermined DVD format by the formatter 32 and supplied to the data processor unit 16. Note that a buffer memory 34 is connected to the formatter 32, and the encoded output signal is buffered. Specifically, the encoded digital video signal, digital audio signal, and sub-picture data are packed by the formatter 32 to become a video pack, an audio pack, and a sub-picture pack, and these are assembled to form a DVD-video. It is converted into a format defined by the standard (DVD Video format) or a format defined by the DVD-recording standard (DVD VR format).

  Note that the packet elementary stream extracted from the transport stream may be recorded directly on the hard disk of the hard disk drive unit 14 from the encoder unit 30.

  The encoder unit 30 can also supply the compressed digital video signal or digital audio signal directly to the formatter 32 when a compressed digital video signal or digital audio signal is directly input. The encoder unit 30 can also directly supply the digital video signal and audio signal that have been converted from analog to digital to the video mixing unit 56 and the audio selector 52.

  Format data (packs of video, audio, sub-picture data, etc.) and created management information by the formatter 32 are supplied to the hard disk drive unit 14 or the data disk drive unit 12 via the data processor unit 16, and the hard disk or optical disk 10. To be recorded. The format data and management information recorded on the hard disk or the optical disk 10 can also be recorded on the optical disk 10 or the hard disk via the data processor unit 16 and the disk drive unit 12 (hard disk → optical disk / optical disk → hard disk).

  The data processor unit 16 also deletes a part of video objects constituting program data recorded on the hard disk or the optical disc 10 or edits a part of video objects constituting a plurality of different programs. Processing can also be performed.

  The microcomputer block 70 includes an MPU (micro processing unit) or CPU (central processing unit), a ROM in which a control program and the like are written, and a RAM for providing a work area necessary for program execution. . The microcomputer block 70 further includes an electronic program guide processing unit 701, a recording control unit 702, a reproduction control unit 703, an editing processing unit 704, and a display control unit 705.

  Among the execution results of the MPU, contents to be notified to the user are displayed on the display unit 74 of the information recording / reproducing apparatus or displayed on the monitor display connected to the information recording / reproducing apparatus. . The display unit 74 includes an FL tube or an LED, and can display various information even when the main power of the information recording / reproducing apparatus is off.

  The microcomputer block 70 can be connected to an external network via the network interface 72. As a result, an electronic program guide can be taken in via an external network.

  The microcomputer block 70 controls the disk drive unit 12, the hard disk drive unit 14, the data processor unit 16, the encoder unit 30, the decoder unit 50, and the like based on time data from an STC (system time clock) 40. Note that the recording and playback operations are executed in synchronization with the time clock from the STC 40, but other processes may be executed at a timing independent of the STC 40.

  An operation input signal from the key input unit 76 is input to the microcomputer block 70. The key input unit 76 is, for example, operation switches provided on the main body of the information recording / reproducing apparatus and a remote controller independent of the main body. Alternatively, the key input unit 76 may be a personal computer connected to the information recording / reproducing apparatus by wired communication or wireless communication. The key input unit 76 includes, for example, a program guide display key, a calendar display key, a scheduled recording program list display key, a playback program list display key, a delete key, an enter key, and a cross key. And left and right keys. Based on the operation input (selection operation) via the key input unit 76, the information recording / reproducing apparatus performs program recording reservation, program recording based on the program recording reservation, playback of the recorded program, stop of playback, editing of the recorded program ( Delete etc.).

  The decoder unit 50 includes a separator, a memory, a video decoder (a main video decoder and a sub video decoder), an audio decoder, and a video processor. The separator separates each pack from a DVD format signal having a pack structure. The memory is used when performing pack separation and other signal processing. The main video decoder decodes the main video data (the contents of the video pack) separated by the separator. The sub-picture decoder decodes the sub-picture data (sub-picture pack contents) separated by the separator. The audio decoder decodes the audio data (the contents of the audio pack) separated by the separator. The video processor synthesizes the decoded sub-video (menu, highlight button, subtitle, etc.) with the decoded main video.

  The video signal output from the decoder unit 50 is input to the video mixing unit 56. The video mixing unit 56 synthesizes text data, for example. The video mixing unit 56 is connected to a line for directly capturing signals from the AV input unit 18a, the terrestrial analog tuner 18b, the terrestrial digital tuner 18c, the satellite BS / CS tuner 18d, and the satellite analog tuner 18e. A frame memory 58 used as a buffer is connected to the video mixing unit 56. The analog video signal output from the video mixing unit 56 is directly output to the outside via an I / F (interface) 73, and the digital video signal output from the video mixing unit 56 is converted to analog video via a digital / analog converter 62. It is converted into a signal and output to the outside (for example, the monitor 64).

  The digital audio signal output from the decoder unit 50 is converted into an analog audio signal by the digital / analog converter 54 via the selector 52 and output to the outside (for example, a speaker). The selector 52 is controlled by a select signal from the microcomputer block 70. As a result, the selector 52 can directly select a signal that has passed through the encoder unit 30 when directly monitoring a digital signal from the AV input unit 18a or the terrestrial digital tuner 18c.

  The formatter of the encoder unit 30 creates segmentation information during recording and periodically sends it to the MPU of the microcomputer block 70. 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.

  In addition, this information recording / reproducing apparatus determines a minimum information unit that must be continuous in order to continue reproducing a recorded program without interruption while accessing (seeking) data constituting the recorded program. Yes. This information unit recording area is called a CDA (Contiguous Data Area). Information of multiples of ECC (error correction code) blocks (16 sectors) is recorded in the CDA.

  The data processor unit 16 receives data in units of VOBU from the formatter of the encoder unit 30, generates data in units of CDA from the data in units of VOBU, and supplies the data in units of CDA to the disk drive unit 12 or the hard disk drive unit 14. Further, the MPU of the microcomputer block 70 creates management information necessary for reproducing the recorded data. When the MPU recognizes a data recording end command, it sends the created management information to the data processor unit 16. Thereby, management information is recorded.

  Next, reservation recording by the information recording / reproducing apparatus described above will be described. In response to the operation (pressing) of the program guide display key, the electronic program guide processing unit 701 and the display control unit 705 of the microcomputer block 70 display the electronic program guide on the monitor 64. In response to the operation (pressing) of the cross key while the electronic program guide is displayed on the monitor 64, the cursor moves on each program cell of the electronic program guide. In response to the operation (pressing) of the enter key with the cursor positioned at the desired program cell, the desired program is reserved for recording. By repeating this procedure, recording of a plurality of programs can be reserved. The recording control unit 702 records a program based on the recording reservation.

  Next, the calendar function by the information recording / reproducing apparatus described above will be described. In response to the operation (pressing) of the calendar display key, the display control unit 705 of the microcomputer block 70 displays a calendar for one month as shown in FIG. In this calendar, one column indicates one week, one row indicates a plurality of weeks by a matrix indicating a plurality of different days of the same day, and one cell among a plurality of cells configured by the matrix indicates one day.

  Recorded program information is added to a past cell corresponding to a past date in the calendar, and recording reservation information is added to a future cell corresponding to a future date. Note that recorded program information and recording reservation information are mixed in the current cell corresponding to the current date of the calendar. These current cell, past cell, and future cell are distinguished and displayed by color coding or the like. In the calendar shown in FIG. 2, the cursor is positioned in the cell indicating the 18th day. In addition to the daily calendar shown in FIG. 2, a weekly or monthly calendar may be used.

  In the calendar shown in FIG. 2, for example, priority is given to displaying a one month schedule outline on one screen, and therefore the amount of information that can be displayed per cell is limited. That is, the amount of information that can be displayed per cell is determined. If the information amount of the recorded program information or recording reservation information to be displayed for one cell exceeds the information amount that can be displayed in one cell, the display control unit 705 records video displayed in one cell based on the display priority. The reservation information or the recorded program information is narrowed down and displayed. The display priority is determined based on, for example, the broadcast time, the recommendation level based on the preference learning result, the playback state (not played / played), and the regularity of the broadcast (every week, every day).

  In addition to the above-described recording reservation information and recorded program information, various marks as shown in FIG. 3 are displayed on the calendar shown in FIG. For example, a mark indicating that recording is in progress is displayed in association with the recording reservation information (title) (see the mark associated with “News B” in the cell indicating the 18th day in FIG. 2).

  If there is a recommended program, a mark indicating that it is a recommended program is displayed in association with recommended program information (title) (corresponding to “baseball relay” in the cell indicating one day in FIG. 2). And a mark reference associated with “baseball broadcast” in the cell indicating the 23rd day in FIG. 2). For example, the recommended program information is searched based on the preference learning result and the electronic program guide. The microcomputer block 70 learns the preference based on the operation (recording reservation, recording, reproduction) of at least one of the recording control unit 702 and the reproduction control unit 703, and the recommended program information includes the learning result of the preference and the electronic Search based on program guide. For example, if it becomes clear from the learning result of the preference that the user's preference is baseball broadcast, the baseball relay is searched from the electronic program guide, and the program information (title) indicating the baseball relay is a recommended program. The mark which shows is provided.

  In addition, when recording based on the recording reservation information fails due to a lack of recording destination capacity or the like, recording failure information is displayed in association with this recording reservation information (for example, in the cell indicating the 17th day in FIG. 2). (See the mark associated with “Drama A” in the middle).

  In addition, when automatic deletion conditions are set (settings such as automatic deletion of programs that have been automatically recorded based on the learning result of preference and have passed a predetermined period of time), recording that is subject to automatic deletion Automatic deletion information is displayed in association with the program information (for example, see the mark associated with “World Soccer” in the cell indicating the 22nd day in FIG. 2). Note that the edit processing unit 704 automatically deletes the recorded program corresponding to the automatic deletion condition based on the setting of the automatic deletion condition.

  Also, the recording capacity shortage occurrence information is displayed on the cells after the predicted occurrence date of the shortage of recording capacity based on the recording reservation information (see, for example, the mark associated with each cell indicating the 30th day and after in FIG. 2). By looking at this recording capacity shortage occurrence information, the user can know that there is a possibility that the recording may fail in the near future due to insufficient capacity of the recording destination (for example, hard disk). Further, the occurrence prediction of the recording capacity shortage based on the recording reservation information is guided and displayed by the FL tube or LED of the display unit 74. With the FL tube or LED, even when the main power supply of the information recording / reproducing apparatus is turned off, it is possible to know the occurrence prediction of insufficient recording capacity.

  FIG. 7 is a flowchart illustrating an example of a recording capacity shortage occurrence prediction process. As shown in FIG. 7, the recording control unit 702 records a recording destination (for example, a hard disk) based on recording reservation information, recorded program information (recorded title information), and recorded program information (automatic deletion information) corresponding to an automatic deletion condition. The time when the remaining capacity of becomes zero is calculated. Note that the time when the remaining capacity of the recording destination falls below the predetermined capacity (time when the remaining capacity becomes small) may be calculated (ST201).

  Based on the calculation result, display control unit 705 displays recording capacity shortage occurrence information on the cells after the predicted date when the remaining capacity of the recording destination (for example, hard disk) becomes 0 (ST202). Alternatively, the display control unit 705 displays the recording capacity shortage occurrence information on the cells after the predicted date when the remaining capacity of the recording destination is less than the predetermined capacity (the predicted date when the remaining capacity is little) based on the calculation result.

  Next, with reference to FIGS. 4 and 6, various functions by key input operations via the key input unit 76 in a state where a calendar is displayed will be described.

  When the calendar is displayed and the determination key is pressed (past cell selection operation) with the cursor positioned on the past cell of the calendar (ST101, past cell), the display control unit 705 displays the selected past cell. A list of program information recorded on the indicated date is output (ST102). Further, when the enter key is pressed while the cursor is positioned on predetermined program information in the list, reproduction control unit 703 starts reproduction of the predetermined program (ST103).

  When the determination key is pressed (current cell selection operation) with the cursor positioned on the current cell of the calendar (ST101, current cell), the display control unit 705 schedules recording on the date indicated by the selected current cell. A selection menu for selecting a list of possible program information (program guide) and a list of actually recorded program information is output (ST104). When a list of program information that can be reserved for recording is selected via the selection menu, display control section 705 outputs a list (program guide) of program information that can be reserved for recording on the date indicated by the current cell (ST106). Further, when the enter key is pressed while the cursor is positioned on predetermined program information in the list, recording control unit 702 reserves recording of the predetermined program (ST107). When a list of actually recorded program information is selected via the selection menu, display control section 705 outputs a list of program information actually recorded on the date indicated by the current cell (ST102). Further, when the enter key is pressed while the cursor is positioned on predetermined program information in the list, reproduction control unit 703 starts reproduction of the predetermined program (ST103).

  When the determination key is pressed (future cell selection operation) with the cursor positioned on the future cell of the calendar (ST101, future cell), the display control unit 705 schedules recording on the date indicated by the selected future cell. A list (program guide) of possible program information is output (ST106). Note that an electronic program guide that has the date indicated by the selected future cell and the current time as an initial value may be displayed. Further, when the enter key is pressed while the cursor is positioned on predetermined program information in the list, recording control unit 702 reserves recording of the predetermined program (ST107).

  When a mark is displayed on the cell (ST105, YES), a selection menu corresponding to the displayed mark is output. For example, when a mark indicating automatic deletion is displayed, the display control unit 705 displays a list of deletion candidates and a list of program information (program guide) that can be reserved for recording on the date indicated by the selected future cell. A selection menu to be selected is output (ST108).

  When a list of program information that can be reserved for recording is selected via the selection menu, display control section 705 outputs a list (program guide) of program information that can be reserved for recording on the date indicated by the current cell (ST106). Further, when the enter key is pressed while the cursor is positioned on predetermined program information in the list, recording control unit 702 reserves recording of the predetermined program (ST107).

  When a list of deletion candidates is selected via the selection menu, display control section 705 outputs a list of deletion candidates (ST106). Furthermore, a predetermined program is immediately deleted, saved (dubbed), played, or protected (deletion prohibited state) by a key operation with the cursor positioned on the predetermined program information in this list. (ST110).

  Alternatively, when a mark indicating that the recording capacity is insufficient is displayed, the display control unit 705 displays a program that can be scheduled for recording on the date indicated by the list of recommended deletion candidates, the list of recommended backup candidates, and the selected future cell. A selection menu for selecting a list of information (program guide) is output (ST111).

  When a list of program information that can be reserved for recording is selected via the selection menu, display control section 705 outputs a list (program guide) of program information that can be reserved for recording on the date indicated by the current cell (ST106). Further, when the enter key is pressed while the cursor is positioned on predetermined program information in the list, recording control unit 702 reserves recording of the predetermined program (ST107).

  When a list of deletion recommendation candidates is selected via the selection menu, display control section 705 outputs a list of deletion recommendation candidates (ST112). Further, a predetermined program is immediately deleted, saved (dubbed), or reproduced by a key operation with the cursor positioned on the predetermined program information in this list (ST113).

  When a list of evacuation recommendation candidates is selected via the selection menu, display control section 705 outputs a list of evacuation recommendation candidates (ST115). Furthermore, a predetermined program is immediately deleted, saved (dubbed), or reproduced by a key operation with the cursor positioned on the predetermined program information in the list (ST116).

  Alternatively, when a mark indicating automatic deletion and a mark indicating occurrence of insufficient recording capacity are displayed, the display control unit 705 selects a deletion candidate list, a deletion recommendation candidate list, and an evacuation recommendation candidate list. Then, a selection menu for selecting a list of program information (program guide) that can be reserved for recording on the date indicated by the future cell is output (ST114). Since the selection operation through the selection menu overlaps with the above description, the description is omitted.

  Further, the calendar function shown in FIG. 5 may be adopted instead of the calendar function shown in FIG. For example, when the determination key is pressed (selection operation of mark indicating recording failure) in a state where the cursor is positioned in the past cell including the mark indicating recording failure, the display control unit 705 performs the re-reservation and the selected past A selection menu for selecting a list of program information recorded on the date indicated by the cell is output. When re-reservation is selected via the selection menu, the recording control unit 702 searches the electronic program guide again for programs that failed to be recorded (for example, rebroadcast programs), and re-records the programs that failed to be recorded. make a reservation.

  When the determination key is pressed (current cell selection operation) while the cursor is positioned on the current cell including the mark indicating that recording is in progress, the display control unit 705 displays the date indicated by the selected current cell. A list of program information that can be reserved for recording (program guide), a list of program information that has actually been recorded, and a selection menu for selecting whether to stop recording are output. When the recording stop is selected through the selection menu, the recording control unit 702 stops the recording.

  In the above description, various displays and functions corresponding to the selection of the past cell, current cell, and future cell on the calendar have been described. By selecting a row or column on the calendar (ST117 in FIG. 6), the next display is performed. The display and function like

  For example, the display control unit 705 selects one or more past cells when one or more past cells are included in the selected row based on a selection operation for one row (for example, selection operation for day of the week display). A list of program information recorded on the indicated date is output. When one or more future cells are included in the selected row, a list of program information that can be reserved for recording on the date indicated by the one or more future cells is displayed. Output.

  The display control unit 705 also selects one or more past cells when one or more past cells are included in the selected column based on one column selection operation (for example, selection operation on the left side of the first cell in the column). When a list of program information recorded on the date indicated by the past cell is output and one or more future cells are included in the selected column, recording reservation can be made on the date indicated by the one or more future cells. A list of program information is output.

  The calendar functions described above are summarized below.

  (1) Recorded program information and recording reservation information are displayed in a daily cell on the calendar.
