Abstract

<P>PROBLEM TO BE SOLVED: To prevent all video recording reservations for rebroadcast programs from unconditionally being canceled even if overlapping with another video recording reservation made by a user when automatic video recording for the program which ended in failure is reserved. <P>SOLUTION: A rebroadcasting decision part 106 compares program information of a program information analysis part 103 with program information on failures in reserved video recording stored in a memory 105 to decide whether the program information corresponds to rebroadcasting of the program whose reserved video recording ended in failure. When the automatic video recording reservation and reservation time of rebroadcasting of the reserved video recording failure program decided by the rebroadcasting decision part 105, overlap with a video recording reservation and a reservation time that the user sets, an overlap reservation decision part 107 reserves and sets video recording of a period part having ended in failure before on condition that the period of the failure in reserved video recording does not overlap with the video recording reservation and video recording time that the user sets, and outputs those reservation settings to a video recording execution part 108. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a re-broadcast automatic recording reservation performed when a recording reservation fails in a digital broadcast receiver having a recording reservation function.

In a digital broadcast receiver having a conventional recording reservation function, an EPG (Electric Program Guide: electronic program guide) broadcast receiving and recording device is provided with a reception monitoring means and a power supply monitoring means in an apparatus. Monitor the tuner reception level while recording a program, and if there is a reception level that prevents the image from being displayed or displayed, or if a part or all of the program cannot be recorded due to a power failure, etc. When a re-broadcast of the same program is searched from and there is a corresponding program, the broadcast date and time is automatically set as a recording reservation. (For example, refer to Patent Document 1).
JP 2000-313231 (first page, FIG. 1)

  In the case of a digital broadcast receiver having a conventional recording reservation function, a re-broadcast recording reservation is automatically set as described above, but the re-broadcasting overlaps with a recording reservation separately set by the user. However, since priority is given to the user's recording reservation setting, the re-broadcast recording reservation is canceled and recording cannot be performed.

  It is an object of the present invention to obtain a digital broadcast receiver that solves the problem that the re-broadcast recording reservation is canceled as described above.

A digital broadcast receiver according to the present invention receives a broadcast wave to which EPG program information is added, separates the program information, and outputs a video;
A recording execution unit for recording the video output from the tuner unit;
A program information analysis unit for analyzing EPG program information separated from broadcast waves of the tuner unit;
A scheduled recording monitoring unit for monitoring whether the scheduled recording is normally performed;
A memory for storing program information and time information for which the scheduled recording from the scheduled recording monitoring unit has failed,
A rebroadcast determination unit that compares the program information stored in the memory and the program information of the program information analysis unit, and determines whether the program is a rebroadcast of the program that has failed the reserved recording;
If the re-broadcast determination unit has determined that the scheduled recording has failed, the automatic re-broadcast reservation and reservation time of the program does not overlap with the recording reservation and reservation time set by the user. If the automatic recording reservation partially overlaps with the recording reservation and the recording time set by the user, if the period when the scheduled recording failed does not overlap with the recording reservation and the recording time set by the user, It is configured to include a reservation setting for recording and a duplicate reservation determination unit for outputting these reservation settings to the recording execution unit.

  According to the digital broadcast receiver of the present invention, the rebroadcast determination unit compares the program information stored in the memory that has failed in reserved recording with the program information of the program information analysis unit, and rebroadcasts the program that has failed in reserved recording. The overlap reservation determination unit determines whether the re-broadcast determination unit determines the automatic recording reservation and the reservation time of the re-broadcast of the program that has failed the reserved recording, and the recording reservation and the reservation time set by the user. If there is no overlap, the entire rebroadcast is reserved, and if the automatic recording reservation for the rebroadcast partially overlaps the recording reservation and the reservation time set by the user, the recording reservation for which the scheduled recording failed is set by the user When the recording time does not overlap with the recording time, the recording of the period portion in which the previous recording has failed has been reserved, and these reservation settings are output to the recording execution unit. Even if they are duplicated, if the previous failed recording period does not overlap, the re-broadcast recording reservation will not be cancelled. For those who really want to watch, there is an effect of canceling the recording reservation so that there is no need to worry about overlooking again.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a configuration of a digital broadcast receiver according to an embodiment of the present invention, and FIG. 2 shows extraction of program information and time information during a period when recording was not performed normally when the digital broadcast receiver was reserved for recording. FIG. 3 is a flowchart showing the recording reservation setting of the rebroadcast program of the digital broadcast receiver, and FIG. 4 explains the operation for reserving the recording by rebroadcasting extracted only during the previous recording failure of the digital broadcast receiver. It is a time chart for doing.

  In FIG. 1, a digital broadcast receiver 101 receives a broadcast wave to which EPG (Electric Program Guide) program information is added, separates the program information, and outputs a video. The program information analyzing unit 103 for analyzing the EPG program information separated from the recording program, the reserved recording monitoring unit 104 for monitoring whether or not the reserved recording is normally performed, and information and time information of the program for which the reserved recording has failed are stored. The memory 105, the program information in the memory 105 and the program information of the program information analysis unit 103, and a re-broadcast determination unit 106 for determining whether it corresponds to re-broadcast, and adjusting the set time for overlapping recording reservations A duplicate reservation determination unit 107 and a recording execution unit 108 that actually records in or outside the digital broadcast receiver are provided.

Then, reception level information 201 is sent from the tuner unit 102 to the reserved recording monitoring unit 104, and recording device information 202 is sent from the recording execution unit 108.
Also, program information 203 is sent from the tuner unit 102 to the program information analysis unit 103, program information 204 is sent from the program information analysis unit 103 to the reserved recording monitoring unit 104, and the program information analysis unit 103 sends it to the rebroadcast determination unit 106. Program information 205 is sent.

Further, the program information and the failure time information 206 for which the scheduled recording has failed are sent from the scheduled recording monitoring unit 104 to the memory 105, and the program information and the failed time information 207 for which the scheduled recording has failed are sent from the memory 105 to the rebroadcast determination unit 106.
Further, a rebroadcast reservation recording request 208 is sent from the rebroadcast determination unit 106 to the duplicate reservation determination unit 107, and a recording reservation 209 set by the user is sent to the duplicate reservation determination unit 107, and a recording is performed from the duplicate reservation determination unit 107. A reservation recording execution request 210 is sent to the execution unit 108, and a video / audio output 211 is sent from the tuner unit 102 to the recording execution unit 108.

Next, extraction of program information and time information during a period when recording was not normally performed at the time of recording reservation in the digital broadcast receiver according to the embodiment of the present invention will be described based on the flowchart of FIG.
During execution of the scheduled recording (step S301), the scheduled recording monitoring unit 104 monitors whether the recording state is good based on the reception level information 201 acquired from the tuner unit 102 and the recording device information 202 acquired from the recording execution unit 110. (Step S302).

Then, if the scheduled recording monitoring unit 104 determines that the recording level is not normal because the reception level is low or an abnormality has occurred in the recording device, that is, the recording state is unsatisfactory, The program information 204 of the recorded program is obtained from the program information analysis unit 103, and the program information and the time information 206 of the failed period are stored in the memory 105 (step S303).
Also, if the scheduled recording monitoring unit 104 determines that the recording state is good, it determines whether or not the scheduled recording has ended (step S304). Steps S302 and S303 are repeated until.

Next, the automatic reservation recording setting operation for rebroadcasting of a program whose recording has failed will be described based on the flowchart of FIG.
First, the rebroadcast determination unit 106 obtains the program information 205 from the program information analysis unit 103 (step S401), and compares it with the previously recorded program information stored in the memory 105 and the time information 207 of the failed period. (Step S402).

If the rebroadcast determination unit 106 determines that the same program is rebroadcast (step 403), the time information of the period in which the previous recording failed is reset according to the rebroadcast time, and the result is set as the program. Together with the information, it is transmitted to the duplicate reservation determination unit 107 as a rebroadcast reservation recording request 208.
The overlap reservation determination unit 107 compares the received rebroadcast reservation recording request 208 with the recording reservation 209 set by the user to determine whether or not the recording times overlap (step 404). The entire rebroadcast program is set for recording reservation (step 405).

  When the received rebroadcast reservation recording request 208 and the recording reservation 209 by the user partially overlap, the overlapping reservation determination unit 107 resets the time information in which the previous recording failed and the recording reservation 209 by the user. (Step 406), and if the period does not overlap with the recording reservation 209 by the user, only the failed period is set as the recording reservation (step 407). If the period also overlaps, setting the re-broadcasting to the recording reservation itself is canceled (step 408).

Next, the operation of setting a recording reservation by rebroadcasting only during the above-described period in which the previous recording has failed will be described in detail with reference to the time chart of FIG.
In FIG. 4, as shown in Case 1, when the recording reservations 1 and 2 set by the user do not overlap at all with the automatic recording reservation setting of the rebroadcast, the recording reservation is set so that the rebroadcast can record all the programs. be able to.

  As shown in Case 2 in FIG. 4, when the recording reservation setting 3 by the user and the automatic recording reservation setting of rebroadcast partially overlap, the previous recording failed in the automatic recording reservation of rebroadcast. When period 1 and period 2 exist, period 1 in which the previous recording failed is overlapped with recording reservation setting 3 by the user, and therefore user including period 1 in which recording recording setting 3 by the user is prioritized and prior recording has failed The part that overlaps with the recording reservation setting 3 by the user cannot set the recording reservation for the rebroadcast, but the period 2 in which the previous recording has failed does not overlap with the recording reservation setting 3 by the user. Only the failed period 2 is set as a recording reservation for rebroadcasting.

  Also, as shown in Case 3 in FIG. 4, when the recording reservation setting 3 by the user and the automatic recording reservation setting for rebroadcast partially overlap as in Case 2, of the automatic recording reservation for rebroadcast, When there are periods 1 and 2 in which previous recording has failed, period 2 in which previous recording failed has overlapped with recording reservation setting 4 by the user, so recording recording setting 4 by the user has priority and previous recording has failed. The portion that overlaps with the recording reservation setting 4 by the user including the period 1 cannot be set for the re-broadcast recording reservation, but the period 1 in which the previous recording failed has overlapped with the recording reservation setting 4 by the user. Therefore, only the period 1 in which the previous recording has failed is set as a recording reservation for rebroadcast.

  Furthermore, as shown in Case 4 of FIG. 4, the recording reservation setting 5 by the user overlaps with the automatic recording reservation setting for rebroadcast, and all the periods 1 and 2 in which previous recording failed are also included in the overlap. If it has, the re-broadcast recording reservation itself is canceled, and the recording reservation setting 5 by the user has priority.

  As described above, according to this embodiment, the rebroadcast determination unit 106 compares the program information stored in the memory 105 that has failed in the scheduled recording with the program information in the program information analysis unit 103, and the scheduled recording has failed. It is determined whether or not the program is rebroadcast, and the duplicate reservation determination unit 107 is set by the user with automatic recording reservation and reservation time for the rebroadcast of the program that has failed in the scheduled recording determined by the rebroadcast determination unit 106 If it does not overlap with the recording reservation and the reservation time, the entire rebroadcast is reserved, and if the automatic recording reservation of the rebroadcast partially overlaps with the recording reservation and the reservation time set by the user, the period for which the reserved recording has failed When it does not overlap with the recording reservation and recording time set by the user, the recording of the portion of the period in which the previous recording has failed is reserved, and these reservation settings are output to the recording execution unit 108, Since the scheduled recording of rebroadcast is canceled when it overlaps with the recording reservation and recording time set by the user, it overlaps with the recording reservation by the user and the recording reservation of rebroadcast, and there are multiple periods in which previous recording failed. If all of them are in the overlap, the re-broadcast recording reservation itself is canceled and the recording reservation setting by the user is prioritized, but the recording reservation by the user and the re-broadcast recording reservation partially overlap. If the institutions that still failed to record are not duplicated, the re-broadcast recording reservation will not be canceled, but the failed period can be set as a recording reservation anew. If it is the part that you really want to watch, there is no need to worry about missing again by canceling the recording reservation by the recording reservation by the user.

It is a block diagram which shows the structure of the digital broadcast receiver of embodiment of this invention. It is a flowchart which shows extraction of the program information and time information of the period which was not recorded normally at the time of recording reservation of the digital broadcasting receiver. It is a flowchart which shows the recording reservation setting of the rebroadcast program of the digital broadcast receiver. It is a time chart for demonstrating the operation | movement which extracts only the period which failed in the previous recording of the digital broadcasting receiver, and schedules recording by rebroadcasting.
