Description

  The present invention relates to a video recording / reproducing apparatus, and more particularly, to a video recording / reproducing apparatus capable of reproducing a program.

  2. Description of the Related Art Conventionally, video recording / playback apparatuses that record, move, and copy programs (for example, broadcast programs) to a recording medium such as a hard disk, a removable medium, and a built-in memory, and play back the programs are known.

  Here, since the recording capacity of the recording medium as described above is limited, it is generally performed to secure the recording capacity by manually erasing a reproduced program by a user.

  However, since the operation of manually erasing the reproduced program by the user is complicated, there has been a demand for simplification of the operation.

  Therefore, in the prior art described in Patent Document 1, when a certain ratio (for example, 80%) has been viewed with respect to the recording time of the recorded program, the program is set to be erasable or overwritten. Yes.

  As a result, the above-described prior art automates the deletion of the reproduced program, thereby simplifying the user's operation.

JP 2005-312006 A

  However, in the above-described conventional technology, for example, an erasure determination is not performed in consideration of a difference in program configuration, such as a program composed only of the main part (without commercials) and a program composed of the main part and commercials.

  Therefore, if playback is stopped near the end of a program composed only of the main part (for example, 80% of the recording time of the program), the main part is still erased even though 20% remains. There was a problem of becoming a target of.

  The recording time varies depending on the program, for example, 15 minutes, 30 minutes, 60 minutes, 90 minutes, 120 minutes, and the like.

  Therefore, when the standard for erasing all the programs is set to a certain ratio, the longer the program recording time, the more the unviewed part remains, but the object to be erased. For example, when the recording time of the program is 120 minutes, there is a problem that the program becomes an erasure target program even though there is an unviewed part for about 24 minutes.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a video recording / reproducing apparatus capable of appropriately erasing a program recorded on a recording medium.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

(Embodiment 1)
A video recording / reproducing apparatus according to Embodiment 1 of the present invention will be described.

  First, the configuration of the video recording / reproducing apparatus according to Embodiment 1 of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration of a video recording / reproducing apparatus according to Embodiment 1 of the present invention.

  As shown in the figure, the video recording / reproducing apparatus 1 includes a reproduction control unit 2, a deletion control unit 3, a reproduction unit 5, a determination unit 6, a program recording unit 7, a deletion program information recording unit 8, and an operation input unit. 901, a monitor 902, a speaker 903, an antenna 904, and a receiving unit 905.

  Next, each part of the video recording / reproducing apparatus 1 will be specifically described.

  The operation input unit 901 is a remote control operation input, a key input, or a touch operation input. According to the UI displaying the received input or the input operation, the operation input unit 901 and the playback control unit 2 An input operation is notified to the deletion control unit 3.

  The playback control unit 2 controls the playback unit based on the input operation notified from the operation input unit 901, and performs operations such as program playback, pause, restart, fast forward / rewind, and stop.

  The deletion control unit 3 deletes the first program stored in the video recording unit 701 of the program recording unit 7 based on the input operation notified from the operation input unit 901. At this time, the reproduction information of the program stored in the program information recording unit 702 is deleted and registered in the deleted program information recording unit 8.

  The reproduction unit 5 reproduces the second program stored in the video recording unit 701 of the program recording unit 7 in accordance with a request instructed by the reproduction control unit 2 and outputs the second program to the monitor 902 and the speaker 903. When the reproduction control unit 2 notifies the reproduction stop, the reproduced position information is stored in the program information recording unit 702 as resume information. Further, the determination unit 6 is notified that the reproduction has stopped. Further, the position where the second program is reproduced is stored in the program information recording unit 702 as a reproduction history. At that time, the reproduction history may be saved only when the reproduction time is continued for about 5 seconds or more. By performing this process, it is possible to prevent a problem that a reproduction history is saved when a reproduction position is selected by mistake.

  When receiving the notification that the reproduction of the second program has been stopped from the reproduction unit 5, the determination unit 6 records the reproduction information and program information of the first program stored in the deleted program information recording unit 8. By comparing the reproduction information stored in the unit 702, it is determined whether the information can be deleted or overwritten, and the processing unit 9 is notified of the information on whether or not the information can be deleted.

  The program recording unit 7 includes a recording medium 703 such as an SD memory card, a hard disk drive (HDD), or an internal memory. The recording medium 703 includes a video recording unit 701 in which video data is recorded, and a program information recording unit 702 in which reproduction information for each program of the video data is recorded. Some of the video data and program information stored in the video recording unit 701 and the program information recording unit 702 may be those in which the recording medium 703 is stored by an external device, or the broadcast signal received by the antenna 904 is stored in the receiving unit 905. There is also a case where data converted into a form suitable for is stored.

  The program information recording unit 702 stores information as shown in FIG.

  As shown in the figure, the program information includes a field H101 for registering the program identification number (Prog), a field H102 for registering the recording start date and time, and a field H103 for registering the recording time. , A field H104 for registering a title, a field H105 for registering whether deletion / overwriting is possible, a field H106 for registering a playback history, a field H107 for registering a viewing end, and resume information And a field H108 for registration.

  The deletion program information recording unit 8 stores information at the time of reproduction as shown in FIG.

  As shown in the figure, the deletion program information includes a field H201 for registering the program identification number (Prog), a field H202 for registering the recording start date and time, and a field H203 for registering the recording time. And a field H204 for registering a title, a field H205 for registering a reproduction history, a field H206 for registering a viewing end, and a field H207 for registering resume information.

  In accordance with the notification received from the determination unit 6, the processing unit 9 stores deletion / overwrite permission / inhibition of the program information stored in the program information recording unit 702.

  Next, the operation of the video recording / reproducing apparatus 1 in Embodiment 1 of the present invention will be described with reference to FIG.

  FIG. 4 is a flowchart for determining whether or not a program can be deleted or overwritten when the program is reproduced and the reproduction is stopped.

  The reproduction control unit 2 is activated by an input to the operation input unit 901 (step S301), and the reproduction control unit 2 instructs the reproduction unit 5 to reproduce the second program.

  Next, the reproducing unit 5 that has received the instruction starts reproduction of the designated second program (step S302).

  Next, when playback is stopped due to input to the playback input unit 901 or playback to the end of the second program (step S303: YES), the playback unit 5 stops playback, and resume information and playback history are displayed. The reproduction information is stored in the program information recording unit 702 (step S304).

  Next, the playback unit 5 notifies the determination unit 6 of the stop of playback, and the determination unit 6 stores the title information stored in the deleted program information recording unit 8 and the program information recording unit 702. The title information of the second program is compared to find information of the same title (step S305).

  Next, when there is information of the same title (step S305: YES), the determination unit 6 resumes the resume information stored in the program information recording unit 702 and the resume stored in the deleted program information recording unit 8. The information is compared, and it is determined whether or not the difference is within about 15 seconds (step S306).

  When the difference is about 15 seconds or more (step S306: NO), the determination unit 6 is stored in the viewed end position of the program stored in the program information recording unit 702 and the deleted program information recording unit 8. It is determined whether or not the difference is within about 15 seconds (step S308).

  In step S306 and step S308, when the difference is within about 15 seconds (step S306: YES, step S308: YES), the determination unit 6 investigates the viewing history of the program and views the same part three times or more. To see if it is.

  If the program is viewed three or more times (step S307: YES), the determination unit 6 determines that the program is a program including a favorite part, and notifies the processing unit 9 that deletion / overwriting is not possible. Notification is made (step S307).

  Receiving the notification, the processing unit 9 stores information indicating that deletion is not possible and overwriting is not possible in the program information area of the program information recording unit 702 (step S310).

  On the other hand, if it has not been viewed three or more times in step S307 (step S307: NO), the determination unit 6 notifies the processing unit 9 that deletion / overwriting is possible (step S307).

  Next, the processing unit 9 that has received the notification saves information indicating that deletion is possible / overwriteable in the information area of the program in the program information recording unit 702 (step S309). Thereafter, the process returns to step S101.

  For example, it is assumed that video data of programs A1 to A6 is stored in the program recording unit 7, and program information as illustrated in FIG. 2 is stored in the program information recording unit 702 for each program. Further, it is assumed that deleted program information as shown in FIG. 3 is stored in the deleted program information recording unit 8. The program A1 has the title “Daily News”, and both the end of viewing and the resume information are 00'55 “15. Since the program information of the same title is in B1 of FIG. Since the information is 00'55 "15, it indicates that the resume information of programs with the same title are within an error of 15 seconds. Therefore, it is possible to delete or overwrite A1.

  Further, the title of the program A2 is “animation”, and the end of viewing and the resume information are both 00'05 “20. Since there is no program information of the same title in FIG. 3, it is possible to delete or overwrite A2. Is no.

  In the program A3, the title is “movie”, the watched end is 01'55 "20, and the resume information is 01'05" 00. Since the program information of the same title is in B2 of FIG. 3, when the comparison is performed, the end of the viewed end is 01'55 "20, so the error between the end of the viewed end of the program of the same title is within 15 seconds. Therefore, it is possible to delete or overwrite A3.

  In addition, the program A4 has the title “music program”, the viewing end is 00'55 "15, and the resume information is 00'19" 10. Although the program information of the same title is shown in FIG. 3, the viewing history of A4 includes the viewing of the same part three times or more, so whether or not A4 can be deleted / overwritten as a favorite program is denied. .

  Note that before the deletion control unit 3 registers the information of the program in the deletion program information recording unit 8, the user may be operated by performing a display as shown in FIG.

  Note that before the determination unit 6 notifies the processing unit 9 of the information of the program, the display may be performed as shown in FIG. 9 or FIG.

  According to the video recording / reproducing apparatus in Embodiment 1 of the present invention, after reproducing the video data recorded in the video recording unit 701, it is determined whether or not the program indicated by the video data has been viewed. It is possible to automatically delete a program when there is no more free space in the program recording section and create a free space. When a user records a program, the program with the same title is often recorded continuously (every week, every weekday period, etc.). Therefore, it is possible to make a judgment according to the situation of each title by using program information (reproduction history, end of viewing, resume information) of the same title that is similar in how to view each time. When deleting a program that has already been viewed, the program information of the program to be deleted is retained, and when the program with the same title is viewed, the deleted program information is used by the previous user manually. It can be used as a judgment material whether or not the user is viewing up to the same position as that, and more accurate judgment is possible.

  In addition, a user may watch a program that the user likes many times. In this case, it can be excluded from the deletion by determining that the program is a favorite program.

  Further, according to the present embodiment, since the deleted program information is stored in the deleted program information recording unit 8, this information can be confirmed at a glance on a screen such as a menu.

(Embodiment 2)
A second embodiment of the present invention will be described. The video recording / playback apparatus according to the second embodiment of the present invention is configured such that the deletion program information can be transmitted / received to / from a server on an external network in the first embodiment.

  FIG. 11 is a block diagram showing the configuration of the video recording / reproducing apparatus in Embodiment 2 of the present invention. In FIG. 11, the same components as those in FIG.

  As shown in the figure, the video recording / playback apparatus according to the second embodiment of the present invention is different from the video recording / playback apparatus according to the first embodiment shown in FIG. 1 in that a communication unit 906 that communicates with an external network and a program information The program information transmission / reception unit 10 for controlling transmission / reception is provided. The points not particularly mentioned in the second embodiment are the same as those in the first embodiment.

  In FIG. 11, the determination unit 6 operates when the reproduction of the second program is stopped, and requests the program information transmission / reception unit to acquire the program information during the determination process.

  The program information transmission / reception unit 10 acquires program information of the designated program using the communication unit 906 based on the program information acquisition instruction notified from the determination unit 6.

  The communication unit 906 communicates with an external network according to instructions from the program information transmission / reception unit.

  When the deletion control unit 3 deletes the second program stored in the video recording unit 701, the program information is stored in the deletion program information recording unit 8, but at the same time, the program information transmission / reception unit 10 The program information of the program is transmitted.

  The program information transmission / reception unit 10 transmits the program information of the designated second program using the communication unit 906 based on the program information transmission instruction notified from the deletion control unit 3.

  Next, the operation of the video recording / reproducing apparatus in Embodiment 2 of the present invention will be described.

  In FIG. 12, when the playback unit 5 plays back the second program and stops playback, the determination unit 6 determines whether or not deletion / overwrite is possible. It is the flowchart which showed whether information is determined.

  First, when the determination unit 6 tries to acquire the deletion program information related to the program from the deletion program information recording unit 8, if the related program information is stored (step S401: YES), the deletion program information recording is performed. The information in section 8 is used (step S405).

  When there is no related deletion program information (step S401: NO), the determination unit 6 requests the program information transmission / reception unit 10 to acquire the deletion program information from the server.

  The program information transmitting / receiving unit 10 that has received the request uses the communication unit 906 to acquire deleted program information related to the program from the server (step S402).

  Next, when the deleted program information of the same title exists on the network (step S403: YES), the program information transmission / reception unit 10 acquires the deleted program information on the network and notifies the determination unit 6 of the acquired information.

  The determination unit 6 notified of the deletion program information stores the notified deletion program information in the deletion program information recording unit 8 (step S404). The determination unit 6 performs a determination process using the deleted program information stored in the deleted program information recording unit 8 (step S405).

  FIG. 13 is a flowchart showing a deletion program information storage process that operates when a program stored in the program recording unit 7 is deleted.

  An operation input by the user to the operation input unit 901 is notified to the deletion control unit 3 (step S501), and the deletion control unit 3 deletes the designated program stored in the program recording unit 7.

  At this time, if there is no program information of the same title in the deleted program information recording unit 8, the deletion control unit 3 stores the program information stored in the program information recording unit 702 in the program information recording unit 8 (step S503).

  Next, the deletion control unit 3 instructs the program information transmission / reception unit 10 to store the deletion program information.

  Receiving the instruction, the program information transmitting / receiving unit 10 uses the communication unit 906 to check the state of the deleted program information on the server (step S503), and if there is no information of the same title, stores the deleted program information in the server. (Step S504).

  According to the video recording / playback apparatus in the second embodiment of the present invention, even when the program has a title that has not been viewed by the user yet, other users have already viewed the program and the deletion program information is stored in the server. By using that information, it is possible to determine whether or not the program has been viewed and to automatically delete the program. In addition, the deletion program information created by the user's own operation is stored in the server, so that other users can use the information.

  In the program A5 in FIG. 5, the title is “news”, the end of viewing is 00'55 "00, and the resume information is 00'05" 00. Looking at the sequence of the playback history, it appears that the end of the program is being played first and then playing from the beginning of the program. In this manner, when an interval of a specific number of seconds (for example, 150 seconds) or more is opened between the reproduction history and the reproduction history that are not reproduced at the same position, the viewed end is the same as the title in FIG. Even if it is the same as the deletion program information B4, it may be determined whether deletion / overwriting is possible. As a result, the determination unit 6 can determine that it has started watching from the vicinity of the beginning of the program after first watching the end of the program and has not watched the main part.

  In addition, when information indicating the contents of the program assigned to the program (for example, 00'01 “00-00'43” 30 is the main part, 00′43 ”30-00'45“ 00 is commercial ”) can be acquired. If it is compared with this information and the reproduction of the main part is not completed, it may be determined whether or not deletion / overwriting is possible. Thereby, the determination part 6 can determine more accurately that the main part of the whole program is not viewed.

  Further, in the program A6 of FIG. 5, the viewed end is 00'55 "00 and the resume information is 00'44" 00. Looking at the sequence of the playback history, it appears that the end of the program is played first, then it is played from near the beginning of the program, and it is played back to the point where it was first seen. In this way, when an interval of a specific number of seconds (for example, 150 seconds) or less is opened between a reproduction history and a reproduction history that are not reproduced at the same position, the viewing end is the same as the title in FIG. Since it is the same as the deletion program information B4, it may be possible to delete / overwrite. As a result, the determination unit 6 can determine that the main part has been viewed after the end of the program is first viewed and then started from the beginning of the program.

  In addition, when information indicating the contents of the program assigned to the program (for example, 00'01 “00-00'43” 30 is the main part, 00′43 ”30-00'45“ 00 is commercial ”) can be acquired. If the reproduction of the main part is completed by comparing with this information, deletion / overwriting may be permitted. As a result, the determination unit 6 can more accurately determine that the main part of the entire program is being viewed.

  Further, in the program A7 of FIG. 5, the viewed end is 00'55 "00, and the resume information is 00'44" 00. Looking at the sequence of playback histories, it seems that after the end of the program is played first, it is played from near the beginning of the program, and it is played back to the point where it was played for the first time after skipping one minute in the middle. In this way, when there are only a plurality of intervals less than a specific number of seconds (for example, 150 seconds) between the playback history and the playback history that are not playing back the same position, Since it is the same as the deletion program information B4 in FIG. As a result, the judging unit 6 has watched the main part of the program even after watching the end of the program first and then starting to watch from the vicinity of the beginning of the program and then skipping the commercial. Judgment can be made.

  Information indicating the contents of the program assigned to the program (for example, 00'01 “00-00'05” 00 is the main part, 00′05 ”00-00'06” 30 is commercial, and 00′06 ”30- 00'43 "30 is the main part, and 00'43" 30-00'45 "00 is commercial). If it is compared with this information and the main part has been played back, it will be deleted / overwritten. It may be possible or not. As a result, the determination unit 6 can more accurately determine that the main part of the entire program is being viewed.

  Further, in the program A8 of FIG. 5, the viewed end is 00'55 "00, and the resume information is 00'46" 00. Looking at the sequence of the playback history, it seems that after playing the end of the program first, it plays from the beginning of the program and plays to the position where it overlaps with the first played position. In this way, when the reproduction history and the reproduction history are combined and only an interval of a plurality of specific seconds (for example, 150 seconds) or less is opened, the viewed end is the same as the deletion program information B4 in FIG. Since it is the same as, deletion / overwrite permission may be permitted. As a result, the determination unit 6 can first determine the end of the program, then start watching from the vicinity of the beginning of the program, and then determine that the main part of the program is being viewed.

  The program information stored in the deleted program information recording unit may be overwritten by program information created when a newer program having the same title is deleted. Thereby, the deletion program information recording part can be updated to more accurate program information.

  It should be noted that the resume information H108 and the viewed end H107 are subtracted from the recording time H103 of the program, rather than determining whether the range of error from the resume information and the viewed end time is constant. A comparison may be made between the numerical value and the numerical value obtained by subtracting the resume information H207 or the viewed end H206 from the recording time H203 of the deletion program information, and it may be determined that the viewing has been completed if the error is within a certain range. Thereby, for example, even when the last time of the series drama is particularly long, it is possible to automatically determine whether deletion or overwriting is possible.

  Note that the viewing end may be determined as the viewed end only when the reproduction is continued for about 10 seconds. As a result, even if the viewing position is advanced due to an operation error, the viewing end position is not set to an unintended position due to an erroneous operation when the viewing position is not viewed for about 10 seconds. I can do it.

  Note that the end of viewing and the resume information may be displayed on the screen so that the user can view and edit. Thereby, the deletion program information recording part 8 can be updated to more accurate program information.

  It should be noted that the viewing history is checked in FIG. 4 to check whether or not the same part is viewed three or more times. If the same part is viewed three or more times, the program is set to be not erasable / overwritten. Only areas that have been viewed more than once may be set to be non-deletable / overwritten, and other areas may be deleted / overwritten. Thereby, the program recording part can distinguish the important part which wants to watch repeatedly, and the part which may be deleted.

  Note that the viewing history is checked in FIG. 4 to confirm whether or not the same part is viewed three or more times.
