Description

  The present invention relates to a video recording apparatus, and more particularly to a video recording apparatus that transmits video data recorded by a video recording apparatus to a video editing apparatus or a video public server at a remote location by network transmission.

  In recent years, as represented by the spread of WiMAX, wireless LAN hotspots in towns are increasing. As a result, it has become practical to upload digital data such as photographs taken with a digital camera from a wireless LAN hotspot to a personal computer or server at home, an online service, or a lab store via a network (for example, the following) (See Patent Document 1).

  In the example of Patent Document 1 below, a camera including a data communication unit that transfers image data of a subject and identification data corresponding to the image data, a storage unit for photographing frame storage, and a storage unit for transfer image data is provided. Presented. As a result, the user can place an order for DP processing or the like from a wireless LAN hotspot or the like via the network, so there is no need to deliver the recording medium to a development shop or a DP reception store. Will not be applied.

Patent Document 1 below further discloses a camera that erases transferred image data based on a normal reception signal or reception ID number transmitted when the transfer of video data is normally completed. As a result, by effectively utilizing the recording medium built in the camera, high-quality photography can be performed without preparing a large number of recording media.
JP 2005-168056 A

  However, in the conventional example shown in Patent Document 1, the data handled is a still image. Further, the signal returned from the data receiving side to the camera was only a signal indicating whether or not the transfer was successful. Therefore, when the conventional example is applied to a video recording apparatus in which data to be handled is a moving image, there are the following problems.

  First, in general, moving image data has an extremely large data size compared to still image data, and there is a problem due to that. In other words, since it takes a very long time to check whether the moving image data that has been transferred and received is broken due to a transmission path error, etc., the receiving side notifies the normal end immediately after receiving the moving image data. May not be returned to the video recording device.

  Furthermore, when the video recording apparatus uses a removable medium such as a memory card as a recording medium, the receiving side takes time to check the error of the received moving image data and then sends a normal reception signal to the video recording apparatus. Is returned, there is no guarantee that the recording medium is connected to the video recording apparatus at that time. Further, since there is no guarantee that the recording medium will be connected to the video recording apparatus again, there is a problem that the timing for erasing moving image data that has been transferred from the recording medium is lost.

  Also, if you want to immediately delete the moving image data from the recording medium built in the video recording device when the transmission ends normally, if you want to play back and check the deleted moving image data on the video recording device side, It becomes necessary to re-acquire moving image data over a network. Therefore, there is a problem that convenience is deteriorated. Therefore, in order not to deteriorate the convenience, it is preferable to postpone the action of deleting the moving image data until the capacity of the built-in recording medium of the video recording apparatus is full. However, in that case, the number of contents recorded in the built-in recording medium of the video recording apparatus becomes very large, and the user decides which contents of moving image data can be erased when erasure is necessary. A troubled situation arises.

  Therefore, the present invention has been made in view of the above-described circumstances, and provides a video recording apparatus that enables a user to determine the selection of content to be erased and to erase content safely and efficiently. With the goal.

Presenting means for presenting as a video file to be deleted with priority, selection accepting means for accepting a video file selected from the video files presented by the presenting means, and deleting the video file accepted by the selection accepting means A deletion means is provided.

  Further, the presenting means may present a video file to be deleted preferentially by displaying the video file with an icon which is predetermined still data associated with the video file.

  The importance level includes information indicating whether or not the video file has been destroyed due to a transmission path error, and the determination means includes information indicating that the video file is not destroyed due to a transmission path error. If the video file is included in the importance level, the video file may be determined as a video file with a lower importance level.

  Further, the transmission destination device is an editing device, and the importance level further includes editing information indicating whether or not the video file has been adopted for editing by the editing device, and the determination means further includes the video file. Is included in the importance level, the video file may be determined to be a video file with a lower importance level.

  Further, the transmission destination device is a video publishing server, and the degree of importance further includes a degree of evaluation of the video file performed by a viewer who has viewed the video file on the video publishing server, and the determination unit further includes: If the importance level includes a low evaluation level for the video file, the video file may be determined to be a video file having a lower importance level.

  Further, the importance level further includes information indicating whether or not the video file is in a public state on the video public server, and the determination unit further includes the video file in a public state on the video public server. Is included in the importance level, the video file may be determined as a video file having a lower importance level.

After the confirmation, the CHECKED-UMID search unit 210 notifies the transmission result inquiry unit 122 of a signal indicating one of the following three states.

  The CHECKED-UMID search unit 210 transmits a signal indicating the state of “not checked (NOT-CHECKED)” through the wireless communication unit 201 if the UMID that has been inquired is not included in the check end list 205. 122 is notified. When the inquired UMID is included in the check end list 205 and marked up with the <OK> tag, a signal indicating the state of “CHECKED” is transmitted through the wireless communication unit 201 as a transmission result query. Notification to the unit 122. When the inquired UMID is included in the check end list 205 and marked up with the <NG> tag, a signal indicating the state of “data destruction (BROKEN)” is transmitted through the wireless communication unit 201 to the video recording apparatus. 100 transmission result inquiry unit 122 is notified.

  Next, the transmission result inquiry unit 122 notifies the UMID sorting unit 117 of the status information of each UMID received from the CHECKED-UMID search unit 210 through the wireless communication unit 109. The UMID sorting unit 117 receives status information of each UMID inquired from the transmission result inquiry unit 122 (S106).

  Next, the UMID sorting unit 117 notifies the editing result inquiry unit 114 of each UMID sorted into “sent (SENT)”.

  Next, the editing result query unit 114 notifies the EDITED-UMID search unit 211 of the UMID notified from the UMID sort unit 117 through the wireless communication unit 109. In other words, the editing result inquiry unit 114 inquires of the EDITED-UMID search unit 211 about the state of the edited UMID inquired from the UMID sorting unit 117 (S107).

  Next, the EDITED-UMID search unit 211 scans the use video list 208 recorded on the recording medium 203 of the editing system 200 to check the status of each UMID that has been inquired. After the confirmation, the EDITED-UMID search unit 211 notifies the editing result inquiry unit 114 of a signal indicating one of the following three states.

  The EDITED-UMID search unit 211 sends a signal indicating an “unused (NOT-USED)” state through the wireless communication unit 201 if the UMID that has been inquired is not included in the use video list 208. 114 is notified. When the inquired UMID is included in the use video list 208 and marked up with the <USED> tag, a signal indicating the state of “adopted (USED)” is sent to the editing result through the wireless communication unit 201. Notification to the unit 114. When the inquired UMID is included in the use video list 208 and is marked up with the <TRASH> tag, a signal indicating the status of “not adopted (TARSH)” is displayed as an editing result of the video recording apparatus 100. The inquiry unit 114 is notified.

  Next, the editing result inquiry unit 114 notifies the UMID sorting unit 117 of the status information of each UMID received from the EDITED-UMID search unit 211 via the wireless communication unit 109. The UMID sort unit 117 receives status information of each UMID inquired from the editing result inquiry unit 114 (S108).

  Next, the UMID sorting unit 117 deletes the deletion priority order table 116 based on the status information about each UMID obtained from each of the transmitted list reading unit 115, the transmission result query unit 122, and the editing result query unit 114. All UMIDs are rearranged in the deletion priority order using (S109).

  FIG. 7 is a diagram illustrating an example of the deletion priority order table 116.

  As shown in FIG. 7, for example, a video file having the highest deletion priority order is a video file in a state of “Sent (SENT)”, “Checked (CHECKED)”, and “Non-adopted (TARSH)”. The deletion priority is “1”. Also, the video file having the lowest deletion priority order is a video file in the state of “not transmitted (NOT-SENT)”, and the deletion priority is “10” in FIG.

  Accordingly, in the deletion priority order table 116 shown in FIG. 7, the deletion priority increases in the order of “USED” → “NOT-USED” → “TRASH”, and “NOT-CHECKED” → “BROKEN” → “CHECKED”. It is defined so that the deletion priority increases in order.

  In FIG. 7, it is better not to delete important video files adopted by the editing system 200 from the video recording apparatus 100 in view of the necessity of backup and the possibility that the preview frequency later increases. Priorities are defined based on criteria.

  Further, in FIG. 7, the priority is defined based on the criterion that the video file in the video recording apparatus 100 should not be erased from the viewpoint that it is necessary to retransmit data whose data has been broken on the transmission path.

  In addition, here, when a plurality of video files have the same deletion priority on the deletion priority order table 116, video files with older recording dates and times are sorted as video files with higher deletion priority.

  Note that the priority order shown in FIG. 7 is an example of prioritization and should be freely set for each user based on the operation mode.

  Next, the UMID sorting unit 117 notifies the content display order sorting unit 119 of a deletion priority order UMID list that is a list of UMIDs sorted (sorted) in the deletion priority order.

  Further, the content display order rearrangement unit 119 may acquire information (for example, shooting date, file name, priority) of the video file instead of the still image of the first frame of all the video files in the recording medium 104. In that case, the icon display unit 123 may display information (for example, shooting date, file name, priority) of the video files arranged in descending order of deletion priority by the content display order rearranging unit 119.

  FIG. 8 is a diagram illustrating an example of an icon corresponding to the video file displayed on the icon display unit 123. FIG. 8 shows an example in which the icon display unit 123 displays information (for example, shooting date, file name, priority) of video files arranged in descending order of deletion priority by the content display order sorting unit 119. .

  Next, the user designates an icon corresponding to the video file to be deleted through the delete file specifying unit 121 (S111).

  Next, the deletion file designation unit 121 notifies the file deletion unit 120 of the UMID of the video file corresponding to the icon designated by the user.

  Next, the file deletion unit 120 deletes the video file corresponding to the notified UMID from the recording medium 104 through the file input / output unit 103 (S112).

  As described above, the user of the video recording apparatus 100 deletes the video file in the recording medium 104 based on the deletion candidate priority order of the video file.

  Therefore, the user can select and delete the video file with reference to the deletion candidate priority indicated from the video recording apparatus 100 when deleting the video file from the recording medium 104. That is, the user can easily determine from which video file to delete.

  The transmitted file list 118 is recorded in the recording medium 104 in the video recording apparatus 100, and the used video list 208 and the check end list 205 are recorded in the recording medium 203 in the editing system 200. . The video recording apparatus 100 inquires about the status of the video file that has already been transmitted to the editing system 200 side when the user asks the deletion candidate in the video recording apparatus 100, and indicates the deletion priority order. Therefore, even when the recording medium 104 of the video recording apparatus 100 is removable, it is possible to present an appropriate deletion priority order.

  Therefore, according to the video recording apparatus 100 and the editing system 200 of the first embodiment, the user can determine the selection of the content to be deleted, and the video recording apparatus 100 capable of deleting the content safely and efficiently. Can be realized. That is, even when the removable recording medium 104 is used in the video recording apparatus 100, the moving image data of the content in the recording medium 104 that has been transferred can be safely and efficiently erased. Further, since the priority order of the erasure candidate contents can be indicated on the video recording apparatus 100 side, the user does not get lost in selecting the contents to be erased.

The video evaluation reading unit 808 notifies the video evaluation inquiry unit 706 of the video recording apparatus 700 of the video evaluation of the video file acquired from the read metafile.

  Next, the video evaluation inquiry unit 706 notifies the file classification unit 708 of the video evaluation for each notified video file received through the wireless communication unit 109. The file classification unit 708 receives the video evaluation of each of the inquired video files from the video evaluation inquiry unit 706 (S208).

  Next, the file classification unit 708 classifies the video files included in the “publication completion (READY)” set for each video evaluation acquired from the video evaluation query unit 706 (S209).

  Next, the content display filter 719 obtains a set of file names that meet the conditions from the file classification unit 708 using a filter condition table indicating the deletion priority.

  Here, the filter condition table is a table indicating the deletion priority set in advance by the user or the deletion priority set by the user via the touch screen 113.

  Next, the content display filter 719 acquires the still image of the first frame of the corresponding video file in the recording medium 104 through the file list acquisition unit 108 and transmits the still image to the icon display unit 123.

  The icon display unit 123 arranges the still images acquired in this way in order of higher deletion priority, and displays them together with the file information classified by the file classification unit 708 (S210). The user can select a video file to be deleted by referring to the icon displayed on the icon display unit 123. When the user executes deletion, an icon corresponding to the video file to be deleted is specified through the deletion file specifying unit 121.

  The conditions that can be specified by the user through the filter condition table correspond to the types of sets into which the file classification unit 708 has classified video files. In other words, in the present embodiment, it is possible to specify the states of “not transmitted”, “unreleased”, and “one star” to “five stars”.

  FIG. 15 is a diagram illustrating an example of a filter condition table according to the second embodiment.

  As shown in FIG. 15, the highest deletion priority order is a video file in a state of “SENT (sent)”, “public (completion of publication)”, and “one star”. “1”. Also, the video file having the lowest deletion priority order is a video file in a state of “NOT-SENT (not transmitted)”, and the deletion priority is “7” in FIG. Next, the video file with the lowest deletion priority is a video file in the state of “unpublished (public not completed)”, and the deletion priority is “6” in FIG.

  Accordingly, in the filter condition table shown in FIG. 15, “5 stars” → “4 stars” → “3 stars” → “2 stars” → “stars” in “open” indicating “ready completion (READY)”. The deletion priority is defined so as to increase in the order of “one”.

  Next, the user designates an icon corresponding to a video file to be deleted through the deletion file specifying unit 121 (S211).

  Next, the deletion file designation unit 121 notifies the file deletion unit 120 of the file name of the video file designated by the user.

  Next, the file deletion unit 120 deletes the video file designated by the user notified through the file input / output unit 103 from the recording medium 104 (S212).

  As described above, the user of the video recording apparatus 700 deletes the video file in the recording medium 104 based on the deletion candidate priority order and classification of the video file.

  Therefore, the user can determine which files are unnecessary while checking the state of each video file recorded on the recording medium 104 on the network and the evaluation from the viewer. The file to be deleted can be determined based on the judgment of “Erase from what has been published on the Internet” or “Don't erase high-rated video”.

  As described above, the video recording apparatus and editing system according to the present invention enables the user to obtain advice for determining deletion when deleting a video file from the recording medium 104.

  In the video recording apparatus and editing system of the present invention, a metafile in which an ID unique to the video file is recorded is recorded in the recording medium 104 of the video recording apparatus 700, and the user has inquired about the deletion priority order. At this stage, the file classification unit 708 of the video recording apparatus 700 makes an inquiry to the video disclosure system 800 side through the WWW page confirmation unit 705 and the video evaluation inquiry unit 706. Therefore, even when the recording medium 104 of the video recording apparatus 700 is removable, an appropriate deletion priority order can be presented.
