In accordance with the coded output and the output of the control unit 30, the drive current of the laser driver is supplied to the optical pickup, and the recording process is performed by irradiating the storage area of the optical disc D.

-Recording process etc. Next, operation | movement of the broadcast recording apparatus 10 which has such a structure is demonstrated in detail. First, the operation during recording will be described in detail, including other embodiments. As an input side of the broadcast recording apparatus 10, a communication unit 11 such as a LAN is connected to an external device and communicates with a program information providing server S or the like via a communication path such as the Internet via a modem M or the like. , Download content information, etc. The BS / CS tuner unit 12 and the terrestrial tuner unit 13 select a broadcast signal via an antenna, demodulate it, and input a video signal and an audio signal, and support a wide variety of broadcast signals. For example, it covers terrestrial analog broadcasting, terrestrial digital broadcasting, BS analog broadcasting, BS digital broadcasting, CS digital broadcasting, and the like, but is not limited thereto. Also, it is not always necessary to provide only one. For example, it has two or more tuners for terrestrial analog broadcasting and two or more BS / CS tuners, and functions in parallel in accordance with the reservation recording request. This includes cases where

  The communication unit 11 may be an IEEE 1394 interface, and can receive digital content from an external device on the network. It is also possible to receive a luminance signal, a color difference signal, a video signal such as a composite, and an audio signal from an input end (not shown). These inputs are controlled by the selector 16 controlled by the control unit 30 and the like, and are selectively supplied to the encoder unit 21.

  The encoder unit 21 includes a video and audio analog-to-digital converter that digitizes an analog video signal and an analog audio signal input by the selector 16, a video encoder, and an audio encoder. Furthermore, a sub-picture encoder is also included. The output of the encoder unit 21 is converted into a predetermined compression format such as MPEG and supplied to the previous control unit 30.

  The BS / CS tuner 12 or the like is not necessarily built in, but is externally attached via the data input terminal, and the received digital signal is supplied to the encoder unit 21 and the control unit 30 via the selector unit 16. It is also suitable to do.

  Here, the apparatus shown in FIG. 1 sends information encoded by the encoder unit 21 (pack of video, audio, sub-picture data, etc.) and created management information via the control unit 30 to the hard disk drive unit 18 or the optical disk drive unit. 19 and can be recorded on the hard disk drive 18 or the optical disk D. Information recorded on the hard disk drive unit 18 or the optical disk D can also be recorded on the optical disk D or the hard disk drive unit 18 via the control unit 30 and the optical disk drive unit 19.

・ Editing process etc.
The data editing unit 20 can perform editing processing such as deleting a part of video objects of a plurality of programs recorded on the hard disk drive unit 18 or the optical disc D or connecting objects of different programs.

・ Reproduction processing, etc.
Next, a process for reproducing recorded information will be described in detail including other embodiments. The MPEG decoder unit 23 includes a video processor that appropriately synthesizes the decoded sub-video with the decoded main video, and outputs a menu, a highlight button, subtitles, and other sub-videos superimposed on the main video.

  The output audio signal of the MPEG decoder unit 23 is analog-converted by a digital / analog converter (not shown) via the selector unit 17 and supplied to the speaker, or is supplied to an external device via the I / F unit 27. The selector unit 17 is controlled by a select signal from the control unit 30. Accordingly, the selector unit 17 can directly select a signal that has passed through the encoder unit 21 when directly monitoring the digital signals from the tuner units 12 and 13.

Scheduled recording process Next, based on the electronic program information acquired from the communication unit 11 or the like, the program specified by the operation of the remote controller R or the like of the user using the recording reservation list of FIG. 2 or the program guide of FIG. Recording reservation processing is possible. Based on the reserved recording information (FIG. 3), the program information received by the BS / CS tuner unit 12 or the terrestrial tuner unit 13 is demodulated at the reserved time by the operation of the control unit 30 and the reserved recording unit 42. The video and audio signals thus recorded are recorded (reserved video recording) on, for example, the hard disk drive 18 after being encoded by the encoder 21 and the like.

  In addition, the reservation recording process at this time can be a program tracking process / extension process using electronic program information, and can automatically cope with a program extension, a broadcast time shift, etc. This will be described in detail later.

  The broadcast recording apparatus 10 of this embodiment has a comprehensive function as described above, and performs recording / reproduction processing by the optical disc D or the hard disk drive unit 18 for many sources. Next, the reservation recording process of the broadcast recording apparatus 10 will be described in detail with reference to the drawings.

FIG.

(Program information provision method)
In the broadcast recording apparatus according to the present invention, the program information providing method can be at least the following two methods, but is not limited to this method. For example, the program information is provided via a medium or the like. But you can.

  That is, the program information is obtained through the tuner units 12 and 13 built in the broadcast recording apparatus 10 shown in FIG. 1, and is sent together with the video / audio signal in normal BS / CS / terrestrial digital broadcasting. This is realized by using the program information to come. Here, program identification information for identifying a broadcast program name (event identification information (Event ID), which is an identification number unique to a broadcast date, time, channel, and additional information including a program title) And the program information including the broadcast time information of the program corresponding to the program identification information (for example, including the broadcast start time, the broadcast time, the maximum extension time, etc.) is received together with the audio / video signal included in the broadcast signal. Is extracted and output.

  As the configuration at this time, it is preferable to prepare a system for updating and generating program information inside the broadcasting station T. Further, as shown in FIG. 1, the following program information providing server S or the like is connected to the broadcasting station T to provide the program information to the broadcasting station T, and the broadcasting signal of the broadcasting station T (digital terrestrial, It is also possible to provide program information to the broadcast recording device 10 by superimposing it on analog, satellite broadcast digital, satellite broadcast analog, etc.

  Furthermore, as shown in FIG. 1, it may be acquired using a program information providing server S that provides program information to the broadcast recording apparatus 10 via the communication unit 11 or the like. The program information providing server S includes program identification information for identifying a broadcast program name (event identification information (Event ID), an identification number unique to the broadcast date / time / channel, and additional information including a program title). A program information registration unit 51 for inputting program information including a broadcast time information (for example, including a broadcast start time, a broadcast time, a maximum extension time, etc.) of the program corresponding to the program identification information; A program information storage unit 52 that stores program information input by the program information registration unit 51, and a communication unit 53 that transmits information stored in the program information storage unit 52 to a desired terminal via a network or the like. is doing.

  The program information providing server S having such a configuration is generally provided as a facility of an organization that provides a service, and program information including a broadcast program, program identification information of the broadcast program, and broadcast time information is uploaded in advance. Has been. When the program information is changed, the program information registration unit 51 immediately inputs the change information, and the program information storage unit 52 is updated. At this time, when program information having the same program identification information as the program information already held in the program information providing server S is input, the program information providing server S displays the program information held in the program information storage unit 52. Replace with the latest one. The program information providing server S may be supplied to the broadcast communication apparatus 10 via the communication unit 53, for example, via the Internet, and via the modem M, or as shown in FIG. It is also possible to provide the program information to the broadcast recording apparatus 10 by superimposing it on the broadcast signal (terrestrial digital, terrestrial analog, satellite broadcast digital, satellite broadcast analog, etc.) of the broadcast station T.

  Here, a plurality of pieces of program information (broadcast start time-end time) and, for example, program information having one program as maximum extension time information of the program information are provided. It is not limited to.

(Tracking process: reservation-start recording)
Next, the reservation recording information tracking process according to an embodiment of the present invention will be described in detail with reference to a flowchart. In the flowchart of FIG. 7, for example, the program table of FIG. 12 is displayed on the screen of the receiver 41 in accordance with the user's operation of the remote controller R or the operation unit 32, and a specific program title, here title P <b> 1. By selecting “Winter Sona” with a cursor or the like and specifying it with the enter key or the like of the remote control R, one program is reserved for recording (S11). In such a recording reservation, an event ID possessed by the electronic program information can be acquired, and a recording reservation in a form in which the event ID is retained may be possible.

  At this time, it can be seen that “Winter Sona” is added in the recording reservation list of FIG. An example of the reservation information at this time is as shown in FIG. 4. Here, the channel, the start date and time, the start time, the recording time, the start shift time included in the start time, and the extension included in the recording time are shown. Time, NetworkID, ServiceID, EventID, tracking status, recording destination, image quality, sound quality, reservation name, etc. are specified. Here, the tracking state is managed as 0: no time change, 1: time change, 2: during real-time tracking, 3: change failure / real-time tracking failure, 4: tracking off.

Further, for example, in the recording reservation (basic setting) screen of FIG. 5, “Winter Sona” is reserved for recording, the date and time are shown, and the “tracking” mode is selected on the screen. You can know with the icon. Further, detailed setting is also possible on the recording reservation (detailed setting) screen of FIG. 6, for example, it can be seen that “tracking reservation” which is the tracking processing mode of this embodiment is turned on.
In addition to the method of specifying a program from the program guide in this way, the reservation method starts the Internet via the communication unit 11, for example, by using an e-mail from a mobile phone (not shown) It may be specified, or a method of inputting characters from a personal computer (not shown) via the communication unit 11 and supplying only the program title is also possible. In this case, since the event ID is not necessarily supplied, it is desirable to specify the event ID particularly in the tracking process described later.

  After such reservation processing is completed, as shown in FIGS. 5 and 6, it is first determined whether or not all reservation information is searched on the recording reservation screen (S12). If all the searches have been completed, the process ends here. If all the processes are not completed, if the tracking mode is selected in the area P2 “chase reservation” in FIG. 6 (S12), the control unit 30 and the reservation recording unit / tracking processing unit 42 For example, recording reservation information tracking processing is performed for program information acquired from the communication unit every time the program guide is updated (for example, once or twice a day, but not limited thereto). . That is, if all the reservation information is not searched, one reservation information is acquired from the program information (S14). Then, it is determined whether or not the event ID is included in the reservation information (S15).

  When there is no event ID, the corresponding ch or N (Network) ID / S (Service) ID and the corresponding program table from the start date are searched by the program title name within a range of ± 2 hours of the start time, for example. (S16). If a reserved program is found (S17), the event ID in the program table is stored as the event ID of the reserved recording information (S23). And it progresses to the reservation time change process mentioned later (S24). If no reserved program is found here, the reservation time remains unchanged and the process proceeds to a process for returning the reservation time to be described later (S18).

  Next, in step S15, if it is determined that the event ID is included in the reservation information, the corresponding NID / SID and the corresponding program schedule from the start date are, for example, ± 2 hours of the start time. Search by event ID in the range (S21). If the reserved program is not found (S22), the process proceeds to the process of returning the reservation time described later without changing the reservation time as it is (S18). If the program reserved in step S22 is found, the process proceeds to a reservation time changing process, which will be described later, and the reservation time is changed (S24).

Returning the reservation time FIG. 8 shows a flowchart for returning the reservation time. Here, “returning the reserved time” means that the current reserved recording information is returned to the reserved recording information input by the user in the reservation setting first. (Recording start time of reservation information) is set to (recording start time) − (shift time), and (recording time) is set to (recording time) − ( The extension time is temporarily set (S31). As a result, the scheduled recording information is in a state in which the current scheduled recording information is returned to the scheduled recording information that the user first input in the reservation setting. Then, time overlap with other reservations is confirmed (S32). Here, if there is no time overlap between the reserved time of the reserved recording information and the other reserved recording information (S33), in order to completely return the current reserved recording information to the first reserved recording information, The shift time is set to “0”, and the extension time is set to “0” (S34).

  In step S33, if there is a time overlap between the reserved time of the reserved recording information and the other reserved recording information (S33), the current reserved recording information is the first reserved recording information input by the user. Stop returning to. That is, by changing (recording start time of reservation information) to (recording start time) + (shift time) and changing (recording time) to (recording time) + (extended time), The first scheduled recording information is returned to the previous recording reservation information (S35). Then, the reservation information tracking state is set to (change failure), and the process ends (S36).

  In the flowcharts of FIGS. 7 and 9 and the flowchart of FIG. 10 to be described next, the program reservation information may change as follows. That is, the first reservation information (for example, 6:00 to 7:00) set by the user in the reservation process (S11) in FIG. The second reservation information (for example, 6:30 to 7:30) is updated through the processes of the flowchart of FIG. 9 and the flowchart of FIG. 9. Furthermore, after that, when the program information is updated in the flowchart of FIG. 7, the process shifts to the reservation time change (S24) according to the latest event ID, and according to the latest program information in the flowchart of FIG. 9. However, in step S42, other scheduled recording information (for example, other scheduled information 7:30 to 8:30) is desired to be updated to the third scheduled information (for example, 7:00 to 8:00). ) May be determined to overlap (S42).

  In such a case, the process proceeds to the flowchart of FIG. 8 through step S47, and the first reservation information (6:00 to 7:00) set by the first user in the reservation process (S11). It is determined whether or not it can be returned to (S31). However, at this time, in the steps S32 and S33, the first reservation information (6: 0 to 7:00) also includes other reservation recording information (for example, other reservation information 5:30 to 6:30). Then this may overlap. In this case, as shown in step S35, the reservation information is returned to the second reservation information (6:30 to 7:30) that is the previous reservation information.

  As described above, in the tracking process of the broadcast recording apparatus according to the present invention, the program reservation information is not simply updated to the latest reservation recording information, but the third reservation is performed in consideration of other reservation recording information. It changes to the optimum value as information → first reservation information → second reservation information.

-Mark display etc. At this time, it is preferable to display a mark for the program table for which the reserved recording time cannot be changed to the latest reserved recording time. It is also preferable to change the color or pattern of the reserved zone above.

That is, the tracking process failure is marked with a mark [? By displaying by [Add], it is possible to inform the user of the status of the current tracking process. That is, in FIG. Append means failure of change. It also indicates that real-time tracking has failed. In other words, the program with the same name was not found on the program table, and if it was attempted to change the reservation time for tracking, it overlapped with other reservations, indicating that the program could not be tracked. At this time, it is preferable to change the color or pattern of the reserved zone on the program guide whose time cannot be changed. There are various marks as shown in a region P3 in FIG.
[X ADD] indicates that tracking off is set.
Further, [Addition] (blue display) indicates a state in which the tracking is successful, and indicates that the time change is also successful.
[Following] (green display) is during real-time tracking by program information from broadcast waves.

Further, no mark indicates that there is no time change.

  Further, as shown in FIGS. 3 and 12, this mark can be different for the recording reservation list (FIG. 2) and the program guide (FIG. 12). In the program table of FIG. 12 having a high display density, the tracking process did not work because the program P4 “Kyoto Event” mark (?) Interfered with the lower program “Cheesecake Studio”. You can know that the change has failed.

  As described above, by displaying the mark explaining the status of the tracking process on the recording list according to the situation, the user can intuitively understand the current status of the tracking process. Further, the mark is not displayed only on the recording list, but it is also preferable to display it on a program table, for example, and may be displayed on an individual reservation setting screen (FIGS. 5, 6, etc.). It is also preferable to set to non-display if the display is troublesome according to the user's request. It is also preferable to display the program area on the program guide in a color or pattern so that it can be identified instead of the mark.

・ Reservation time change
FIG. 9 shows a flowchart for changing the reservation time. First, it is determined whether (reservation start time) = (program start time) and (recording time) = (broadcast time) by the operation of the control unit 30 and the reservation recording unit / tracking processing unit 42 (S41). . If the current reservation time satisfies this relationship, the process ends without changing the reservation time.

  If this relationship is not established, when the reservation is changed to the program start time and the broadcast time of the latest program information, it is determined whether or not the reservation time overlaps with other reservation times already reserved (S42). If they overlap, the process jumps to the above-described “return reservation time” (S47).

  If it does not overlap with other scheduled recording times, change (Reserved information shift time) to (Program start time)-(Reserved information recording start time) and set (Reserved information extension time) to Change to (Program broadcast time)-(Reservation information recording time), (Recording start time) to (Recording start time) + (Shift time), and (Recording time) to (Recording time) + ( (Extension time) (S43).

  At this time, if (shift time) = (extended time) = 0 is not satisfied (S44), (tracking status of reservation information) is set to (time change) (S45). As a result, the mark [addition] (blue display) is displayed on the recording list. It is also preferable to display the program area on the program guide in a color or pattern so that it can be identified instead of the mark. If (shift time) = (recording time) = 0, it is assumed that there is no substantial time change, (tracking status of reservation information) is (no time change), and the tracking mark is displayed This is not done (S46).

  By such tracking processing after reservation (when updating the program guide, etc.), reservation recording processing that reflects the latest program information (program time) is further ensured. In addition, displaying the mark in FIG. 3 makes it possible to intuitively explain the situation to the user. It is also preferable to display the program area on the program guide in a color or pattern so that it can be identified instead of the mark.

(Tracking process: Real-time tracking: Recording start-Recording end)
Next, real-time tracking from the middle of recording to the end of recording at the start of reserved recording will be described with reference to the flowchart of FIG. In the flowchart of FIG. 10, the broadcast recording device 10 operates when the scheduled recording start time comes when the control unit 10 and the scheduled recording unit / tracking processing unit 42 function, and the target program is not being broadcast (S51). (Reservation state of reservation information) is set to (real-time tracking) (S52). At this time, it is preferable to display the mark [addition] (displayed in green) on the program guide, the recording reservation list, or the like. Then, the program information is continuously monitored for a predetermined time, for example, 3 hours (S53).

  At this time, the program information is acquired again (S54), and if the event ID of the reservation information is not found in this program information, the program information starts again from step S53 (S55). If the event ID of the reservation information is found in the program information, the start time of the ID is searched for in the program information. If there is no event ID, the program information starts again in step S53 (S56). If the start time of the same ID is found in the program information, the program time is transferred to the “reserved time change” process of FIG. Also, for example, if the event ID and the time cannot be detected even after repeating the determination from step 54 to step S56 for 3 hours, (reservation information tracking state) is set to (real time tracking failure) and the process is terminated. (S58). At this time, it is preferable to display the mark [× additional] in the program guide, the recording reservation list, or the like.

  If the target program is being broadcast in step S51, the program information is acquired (S61), and it is determined whether there is an end time of the same ID in the program information (S62). If there is no end time, it is determined whether or not broadcasting is in progress (S63). If broadcasting is in progress, the program information is checked again from step S61. If the broadcast has ended, the process ends here.

  If the end time of the same ID is found in the program information in step S62, it is determined at this point whether (recording time of reservation information) = (end time of the same ID in program information) − (start time). (S64). If so, the process returns to step S61 to monitor this state. If not, (recording time of reservation information) is changed to (end time of the same ID in program information) − (start time) ( S65) Then, assuming that the tracking status of the reservation information is changed (time change) (S66), at this time, the mark [addition] (blue) is displayed in the program guide, recording reservation list, etc. It is something to be recognized.

  Next, when it is determined in step S56 that the program information has a start time of the same ID, the reservation time change shown in FIG. 11 is performed. That is, in the flowchart of FIG. 11, when the reservation is changed to the start time of the same ID in the program information, it is determined whether or not it overlaps with other reservations (S71). If it is determined that they do not overlap, the (reservation information start time) is changed to (start time of the same ID in the program information) (S72), and then (reservation information tracking state) is changed to (time change) (S73). At this time, the user is made aware of the current situation by displaying [Add] (blue) in the program guide, recording reservation list, and the like.

  In step S71, if it is determined that the reservation is duplicated with other reservations when the reservation is changed to the start time of the same ID in the program information, (tracking status of reservation information) is set to (change failure). (S74). At this time, mark [? Append] is displayed to allow the user to recognize the current state.

  As described above, in the embodiment of the present invention, real-time tracking is performed even after the recording start time is reached, so that it is possible to reliably cope with subtle time changes such as extension of sports broadcasting. It becomes possible. Further, by displaying each mark as shown in FIG. 3, the user can be made aware of the current state in detail. It is also preferable to display the program area on the program guide in a color or pattern so that it can be identified instead of the mark.

  Therefore, according to the present embodiment, the tracking mode is turned on by turning on the tracking reservation (program tracking) icon P2 of the recording reservation in FIG. 6 to follow the start-end time in FIG. 5 in real time. Can be changed.

-Tracking process priority setting Further, in the setting of the priority of one reservation information and other reservation information, the icon P2 on the recording reservation screen of FIG. By switching from OFF to ON, this reservation information is prioritized over other reservation information, and is set for tracking processing. Thus, in the determination in step S33 in the flowchart of FIG. 8, the determination in step S42 in the flowchart in FIG. 9, and the determination in step S71 in the flowchart in FIG. Therefore, reliable tracking processing can be performed without being affected by other reservation recording information, and reliable reservation recording can be performed. This operation is confirmed by the [Register] button on the recording reservation screen of FIG.

-Processing such as scheduled deletion Further, in the broadcast recording apparatus of this embodiment, when the desired scheduled recording information is deleted or invalidated or the time is changed, the functions of the control unit 30 and the scheduled recording unit 42 are responded accordingly. Thus, all other reserved recording information is detected, and control is performed to optimize these time information. This process enables an optimal tracking process according to the current reservation status.

  In addition, the mark indicating the tracking state can be selected to be displayed / hidden by default, and if the user feels troublesome, the control unit 30 or the like can be controlled so that the mark is not displayed. Is possible.

  As described above, according to the embodiment of the present invention, such real-time tracking processing can also support real-time tracking of a program that is advanced (the program start time is earlier than scheduled). In addition, event tracking in real time can be performed every time for repetitive reservations for digital broadcasting and reservations from electronic program information of a type without event ID information.

  Furthermore, the tracking status can be seen at a glance by the mark display, and if there is a possibility of tracking failure, the user can cope in advance. As a result, the number of programs that can be recorded correctly can be improved with the optimal tracking arrangement at all times.

  In addition, the automatic extension result of the reservation can be easily confirmed on the program guide and can give a sense of security at the time of reservation confirmation, and these are surely required as the basic performance of the broadcast recording apparatus. This makes reservation recording processing possible.

  The various embodiments described above enable those skilled in the art to realize this embodiment, but it is easy for those skilled in the art to come up with various modifications of these embodiments, and have the inventive ability. At least, it can be applied to various embodiments. Therefore, the present invention covers a wide range consistent with the disclosed principle and novel features, and is not limited to the above-described embodiments.
