  In recent years, the capacity of HDDs installed in recording devices has increased dramatically, and accordingly, the appreciation for automatic recording has increased. In other words, this is a technique in which the recording device automatically records a predetermined channel based on a certain condition, instead of setting the recording of each program the user wants to record. For example, this is a technique that records all programs for one week for all receivable channels in the HDD.

  However, in the case where all the programs for one week for all the receivable channels are recorded on the HDD, the user does not select and record the program, so the one recorded for the user is not recorded. There is a problem that it is not easy to find and select a desired program to watch from all the programs for a week.

  The present invention has been made in view of the above, and can improve the operability for finding and selecting a desired program to be viewed from all the recorded programs for a certain period of time.

  Exemplary embodiments of a program recording control device and a program recording control method according to the present invention will be explained below in detail with reference to the accompanying drawings.

  An embodiment of the present invention will be described with reference to FIGS. This embodiment is an example in which a digital recorder is applied as a program recording control device.

  FIG. 1 is a block diagram showing a configuration of a digital recorder 101 according to an embodiment of the present invention. The digital recorder 101 according to the present embodiment has four tuner modules that are receiving units for receiving scrambled digital broadcast signals (two are tuners 102 and 112 for receiving terrestrial digital broadcasts, etc. The two units will be described taking BS / CS digital broadcast receiving tuners 122, 132, etc.) as an example.

  Broadcast program signals received by the first tuner 102, the second tuner 112, the third tuner 122, and the fourth tuner 132 are input to the TS re-multiplexing unit 141 that functions as a re-multiplexing unit. The TS (Transport Stream) of the channel (CH) is remultiplexed into one TS. As shown in FIG. 2, as the re-multiplexing method, there is a method of re-multiplexing at 5 times speed in the case of 4CH input, and adding, for example, time stamp information for each packet as a flag. The signal remultiplexed by the TS remultiplexing unit 141 is sent to the TS demultiplexing unit 103.

  The TS separation unit 103 functions as a separation unit, and describes an ECM (Entitlement Control Message) that is encrypted information from a broadcast program signal, and event information such as a program name, performer, and start time. Is separated from the EIT (Event Information Table).

  The ECM separated by the TS separation unit 103 is transferred to the CAS control unit 107. The CAS control unit 107 is a broadcaster stored in a CAS module (a CAS card in the form of an IC card: hereinafter referred to as a CAS card as appropriate) 108 installed in a card slot (card interface I / F) 107a. The encryption of the ECM is decrypted using the work key (Kw) set for each time, and the viewability is determined by comparing the attribute information related to the program in the ECM with the contract information stored in the CAS card 108. . The CAS control unit 107 decrypts the scramble key (Ks) and outputs it to the descrambler unit 104 when viewing is possible. The encryption keys Ks and Kw are different for each broadcaster, but are common to all receivers.

  On the other hand, the EIT separated by the TS separation unit 103 is input to the program database unit 113. The program database unit 113 creates a database for creating a program guide using EIT. FIG. 3 is a schematic diagram showing a data structure of the program database unit 113. As shown in FIG. 3, information such as channel, date, start time, end time, title, recording status, dubbing presence / absence, etc. is tabulated for each program.

  The descrambler unit 104 sets the scramble key Ks responded from the CAS control unit 107, and inputs the descrambled TS to the recording / reproduction control unit 110.

  The recording / playback control unit 110 performs control to return the remultiplexed TS to the TS for each channel and record it in the recording medium unit 111 such as an HDD, and at the same time, TS that is a broadcast program signal recorded in the recording medium unit 111. Is output to the AV decoding unit 105. That is, the recording / reproduction control unit 110 functions as a recording control unit and a reproduction control unit.

  Here, the recording / playback control unit 110 performs physical recording of the recording medium unit 111 as shown in FIG. 4 when recording the broadcast program signal (stream returned to the TS for each CH) on the recording medium unit 111. Metadata in which the recording position (physical address) in the area, time information, and program information are associated is created for each channel and recorded in the recording medium unit 111. In the example shown in FIG. 4, the recording position (physical address) is recorded every 5 seconds. Note that the program information can be acquired from the EIT.

  The recording medium unit 111 is an HDD, a disk drive, or an SD (registered trademark) card reader / writer, and records a TS that is a broadcast program signal from the recording / playback control unit 110. The recording medium unit 111 does not need to be built in the digital recorder 101, and may be a recording medium such as an HDD connected via a USB or a LAN.

  The AV decoding unit 105 receives the broadcast program signal (stream returned to the TS for each channel) of each channel received by each tuner 102, 112, 122, 132 or the broadcast program signal (returned to the TS for each CH) ( The stream returned to the TS for each CH) is decoded into AV information (video and audio).

  AV information decode output (AV output) is output to the display unit 200, which is an external monitor, via the display processing unit 106. Further, the display processing unit 106 has a GUI (Graphical User Interface) function for presenting information to the user by OSD (On Screen Display) or the like. With this GUI function, a program guide, which will be described later, is displayed on the display unit 200.

  The program guide processing unit 115 receives the EIT of the program recorded in the recording medium unit 111 and the EIT of the program to be broadcast in the future from the program database unit 113, thereby executing the program guide creation process.

  The input processing unit 114 receives various inputs from the user. For example, the input processing unit 114 accepts input from the user such as setting of automatic recording and designation of a reproduction program on the program guide. The input processing unit 114 may accept user input from a unit corresponding to a fixed operation panel (not shown) attached to the digital recorder 101, or from a remote controller 300 separated from the digital recorder 101. It may accept user input.

  FIG. 5 is a front view showing the remote controller 300. As shown in FIG. 5, the remote controller 300 includes a channel selection key 301 that accepts channel selection, a cursor key 302 that accepts an up / down / left / right movement instruction, a decision key 303 that accepts a decision instruction, and a channel UP or DOWN instruction. A channel UP / DOWN key 304 for receiving a special reproduction key (fast forward key, rewind key, next program step key, previous program step key, etc.) 305 for receiving a special reproduction instruction are arranged.

  Here, FIG. 6 is a front view showing a display example of a program guide. When displaying a recorded program in units of time including a predetermined time, for example, as shown in FIG. 6, the time axis is set in the vertical direction of the screen, the broadcast time column TM is arranged in the time axis direction, A channel column CN is set in a substantially orthogonal direction, and a program guide that is recorded program information is displayed in the corresponding channel column of the corresponding broadcast time. In addition, a bar B indicating the current time is located at the center in the vertical direction of the screen, that is, the center of the program guide. It is possible to discriminate between past programs and future programs by displaying the bar B indicating the current time, color-coding, or the like. Such a time-unit program table including a predetermined time is particularly effective when, for example, a recorded program in a period set to record all broadcast programs is displayed.

  At this time, for example, the user operates the cursor key 302 of the remote controller 300 and moves the position of the selection frame SL as shown in FIG. 6 to scroll the display screen to search for the recorded program. be able to.

  When the user moves the selection frame SL, the program list display screen may be scrolled so that the selection frame SL is displayed at the center of the screen, and the selection frame SL is moved within the screen. May be.

  Further, for example, the user aligns the selection frame SL with the desired program information column and presses the enter key 303 of the remote controller 300 to operate, so that more detailed information of the recorded program or the program to be recorded is obtained. Can be displayed. Further, the user can operate to selectively delete the program recorded in the recording medium unit 111 from the displayed program information.

  Next, program display processing using a program guide in the digital recorder 101 will be described with reference to FIGS.

[When a program displayed at the current time is selected]
As shown in FIG. 7, when a program broadcast at the current time is selected by operating the enter key 303 of the remote controller 300 (Yes in step S1), the “program” is set in the preset operation setting. If “viewing from the top of” is not selected, normal viewing is performed (Yes in step S2, step S3). During normal viewing, the digital recorder 101 causes the AV decoding unit 105 to input the stream returned to the TS for each CH, thereby displaying the video of the program at that time on the display unit 200.

[When a past program is selected]
On the other hand, when a program before the current time is selected by operating the enter key 303 of the remote controller 300 (No in step S1), the program recorded in the recording medium unit 111 is played back during playback. Mode (step S4).

  As shown in FIG. 8, in the process during playback, the recording / playback control unit 110 searches the recording medium unit 111 for metadata corresponding to the CH and start time of the program selected in the program guide, and the searched metadata is Based on this, the channel reproduction start position is calculated (step S11), the calculated reproduction start position data (TS) is read from the recording medium unit 111 (step S12), and the read TS is input to the AV decoding unit 105 to program. The video of the program selected in the table is displayed on the display unit 200 and played back (step S13).

  In the state where the recorded program is being reproduced in this manner, there is an instruction to switch channels by operating the channel UP key / DOWN key (a key assigned to channel up / down in normal viewing) 304 of the remote controller 300. If there is an instruction to switch the channel using the channel UP key 304 of the remote controller 300 (Yes in step S14) (Yes in step S15), the meta data relating to the broadcast program signal being reproduced as shown in FIG. Based on the time information of the data, the reproduction start position of the previous channel is calculated (step S16), the process returns to step S12, and the stream to be reproduced is switched. That is, data (TS) based on the reproduction start position of the channel that has received a switching instruction at the same time as the calculated reproduction start position is read from the recording medium unit 111 (step S12), and the read TS is input to the AV decoding unit 105. Then, the video of the program selected in the program guide is displayed on the display unit 200 and reproduced (step S13).

  On the other hand, when there is an instruction to switch the channel using the channel DOWN key 304 of the remote controller 300 (No in step S15, Yes in step S17), the metadata of the broadcast program signal being reproduced as shown in FIG. Based on the time information, the reproduction start position of the next channel is calculated (step S18), the process returns to step S12, and the stream to be reproduced is switched. That is, data (TS) based on the reproduction start position of the channel that has received a switching instruction at the same time as the calculated reproduction start position is read from the recording medium unit 111 (step S12), and the read TS is input to the AV decoding unit 105. Then, the video of the program selected in the program guide is displayed on the display unit 200 and reproduced (step S13).

  As a result, programs that have already been recorded can be searched as if they were channel zapping in the same way as normal viewing channel selection. It is possible to improve operability for finding and selecting a program.

  Note that the playback start position at the time of channel switching does not have to be the same time as before the switching, and for example, it is possible to start from the start position of the program from the time information of the metadata as well. It can also be made possible by user settings.

  In other words, the program start position is calculated at the position corresponding to the same time as the time when the program of the currently playing channel is recorded, the start position of the program after channel switching, and an arbitrary offset position after a predetermined time has elapsed from the start of the program. May be calculated as the playback start position.

  If a special reproduction instruction is issued by operating the special reproduction key 305 of the remote controller 300 (No in step S14, Yes in step S19), special reproduction processing is executed (step S20).

  As shown in FIG. 9, in the special reproduction process, when a fast-forward instruction is given by the fast-forward key of the special reproduction key 305 of the remote controller 300 (Yes in step S31), the program is fast-forwarded and reproduced (step S35). If there is a rewind instruction by the rewind key of the special playback key 305 of the remote controller 300 (Yes in step S32), the program is rewinded and played (step S36).

  Further, if there is an instruction to skip the next program in the same channel by the next program skip key of the special playback key 305 of the remote controller 300 (Yes in step S33), the program of the metadata related to the signal of the broadcast program being played back Based on the information, the recording position that is the reproduction start position of the next program for which the switching instruction is accepted is calculated from the metadata (step S37), and the calculated reproduction start position data (TS) is read from the recording medium unit 111 (step S37). S38) The read TS is input to the AV decoding unit 105, and the video of the program selected in the program guide is displayed on the display unit 200 and reproduced (step S39).

  If an instruction to skip the previous program in the same channel is given by the previous program skip key of the special playback key 305 of the remote controller 300 (Yes in step S34), the metadata program related to the broadcast program signal being played back Based on the information, the recording position that is the reproduction start position of the previous program that received the switching instruction is calculated from the metadata (step S40), and the calculated reproduction start position data (TS) is read from the recording medium unit 111 (step S40). S38) The read TS is input to the AV decoding unit 105, and the video of the program selected in the program guide is displayed on the display unit 200 and reproduced (step S39).

  As a result, a program skip function can be added, so that it is possible to further improve the operability for finding and selecting a desired program to be viewed from all the recorded programs for a certain period. .

  In addition, when the current time is exceeded due to selection of the previous program, rewinding, skipping, etc. while viewing the currently broadcast program, the recording position that is the playback start position of the previous program is calculated from the metadata, It is possible to switch to playback of a recorded program from that position.

  Here, FIG. 10 schematically shows a screen transition example of the channel zapping function and the program skip function as described above. In the example shown in FIG. 10, when a channel switching instruction (CH 1 → CH 2 → CH 3 → CH 4) is given by the channel UP key 304 of the remote controller 300 during playback of the recorded program 1-2 before the current time. The recorded programs 2-2, 3-2, and 4-2 are sequentially reproduced according to the time management during reproduction. If the next program skip key of the special playback key 305 of the remote controller 300 is instructed during playback of the recorded program 4-2, the recorded program 4-3 is played back. If the previous program skip key is instructed by the previous program skip key of the special playback key 305 of the remote controller 300 during playback of the recorded program 4-2, the program returns to the beginning of the recorded program 4-1. .

  As described above, according to the program display process using the program guide in the digital recorder 101, it is possible to search for a program in the sense of channel zapping as in normal viewing, and a program skip function is added, so that a program is found. Therefore, the operability can be improved.

[If you select a future program]
If a program after the current time is selected by operating the enter key 303 of the remote controller 300, if there is a detailed explanation of the program or if there is a separate PVR (Personal Video Recorder) function, a reservation to the PVR is made. Displays a menu for recording.

  As described above, according to the present embodiment, the recording / playback control unit 110 performs switching when receiving a channel switching instruction via the input processing unit 114 during playback of a broadcast program recorded on the recording medium unit 111. The position of the broadcast program signal for the channel for which the instruction was received corresponds to the same time as the time when the program of the currently playing channel was recorded, the start position of the program after channel switching, and a predetermined time from the start of the program. By reading from the recording medium unit 111 using any one of the offset positions as a playback start position, it is possible to search for a program already recorded in the sense of channel zapping as in the normal viewing channel selection. You can, so you can find and select the program you want to watch from all the recorded programs for a certain period of time It is possible to improve the.

  That is, when recording a broadcast program signal of each channel received by a plurality of tuners 102, 112, 122, 132 to the recording medium unit 111, the recording position in the physical area of the recording medium unit 111 Metadata associated with time information is created for each channel and recorded in the recording medium unit 111. When a channel switching instruction is received during playback of the broadcast program signal recorded in the recording medium unit 111, the switching instruction is received based on the time information of the metadata related to the broadcast program signal being played back. The recording position that is the channel playback start position is obtained from the metadata, and the broadcast program signal at the playback start position is read from the recording medium unit 111, so that the already recorded program can be selected in the same manner as the normal viewing channel selection. Since program search can be performed in the sense of channel zapping, it is possible to improve operability for finding and selecting a desired program to be viewed from all the recorded programs for a certain period.

  In addition, the metadata of the broadcast program recorded in the recording medium unit 111 is created by creating, for each channel, metadata in which program information is further associated with the recording position and time information and recording the metadata in the recording medium unit 111. When an instruction to switch the broadcast program in the same channel is received during playback of the program, the recording that becomes the playback start position of the program that has received the switch instruction is based on the program information of the metadata related to the signal of the broadcast program being played. The program skip function can be added by obtaining the position from the metadata and reading the broadcast program signal at the playback start position from the recording medium unit, so it can be selected from all programs for a certain period of time. It is possible to further improve the operability for finding and selecting a program to be viewed.

  In this embodiment, the example in which the digital recorder 101 is applied as the program recording control apparatus has been described. However, the present invention is not limited to this, and a digital TV may be applied as the program recording control apparatus.

  In the digital recorder 101 of the present embodiment, the TS remultiplexing unit 141 receives broadcast program signals received by the first tuner 102, the second tuner 112, the third tuner 122, and the fourth tuner 132. In this case, the TS (Transport Stream) of a plurality of channels (CH) is remultiplexed into one TS and then sent to the TS separation unit 103. However, the present invention is not limited to this, as shown in FIG. In addition, broadcast program signals received by the tuners 102, 112, 122, 132 may be sent to the TS separator 103.
