Description

  The present invention relates to video editing, and more particularly, to a technique for specifying an editing location at the same time as viewing a video played back on a recording / playback device.

  In general, when recording and saving a program broadcasted on a television or a captured moving image, an editing operation such as deleting unnecessary portions included in these videos is performed. However, in this editing work, the editing location must be specified according to the content of the video, so that there is a problem that it is necessary to confirm the content of the video a plurality of times, which is troublesome. For example, the start point and end point are specified in order to delete a commercial video included in a TV program, or the start point and end point are specified in order to extract only important parts from the shot video. In this case, the person who performs the editing work has to grasp the content of the video and specify the editing portion, and therefore, the “rewind” and “fast forward” operations are repeated a plurality of times.

  As a means to solve the above problems, in the video recording and playback field, when a user finds a video of a scene (movie trailer, TV commercial, etc.) to be deleted while viewing the video, the scene to be deleted is specified by remote control operation. There is technology to do. In this technology, the video position when the user presses the edit button on the remote control while watching the video is recorded, and when the edit mode is started, the jumping to the recorded video position is performed to reduce the editing operation. Means are used. As a result, the number of times of performing “rewind” and “fast-forward” operations for editing can be reduced. (See Patent Document 1)

JP 2006-5394 A

  By using the technique of Patent Document 1, it is possible to reduce the number of times of performing “rewind” and “fast forward” operations when editing an image. However, even if the user specifies the scene to be deleted while viewing the video with the remote control, the starting point of the scene to be deleted has already passed at the specified time, or how long will the scene to be deleted continue at the specified time? I do n’t know. For this reason, even if the technique of Patent Document 1 can grasp the rough video position of the edited portion, the start point and the end point of the edited portion cannot be specified.

  An object of the present invention is to solve the above-mentioned problems of the prior art.

By configuring as described above, work and costs related to the system configuration of the present invention can be reduced.

Example 1 Treatment Process
Next, an example of a processing process in the video editing support system of the present invention will be described with reference to the functional block diagram of FIG. 3, the flowchart of FIG. In the following description, an example of using an elementary school as a place where the system is used, an elementary school teacher (hereinafter referred to as “teacher”) as a user of the system, and a TV program recorded as an image to be edited by the system is taken as an example. I will explain.

  The terminal control unit 22 of the terminal B acquires the video request instruction input to the terminal B via the terminal input device 24 or the external input device D, and transmits it to the display information receiving unit 21. The display information receiving unit 21 transmits a video request instruction to the management server A via the network I / F 20.

  The above processing will be described by taking the case of using this system in an elementary school as an example. A teacher who is a user of terminal B is connected to terminal B in order to watch a television program (video) recorded for use in his class and stored in management server A before class. Using a keyboard or the like (terminal input device 24) or a remote control (external input device D), video is displayed on the display (terminal display device 23) of terminal B or a monitor or projector (external display device C) connected to terminal B. Is instructed to be displayed. Upon receiving this instruction, the terminal control unit 22 causes the display information receiving unit 21 to generate a video request instruction, and the display information receiving unit 21 transmits the generated video request instruction to the management server A via the network I / F 20. . The video request instruction includes video identification information for uniquely identifying the video requested by the user. In this embodiment, it is assumed that a video request instruction is output so as to display the video identification information “V001”.

  The display control unit 17 of the management server A acquires the video request instruction output from the terminal B via the network I / F 10 (S101), and extracts the video using the video identification information included in the video request instruction. A video acquisition instruction is generated and transmitted to the processing unit 16. This video acquisition instruction includes video identification information. In this embodiment, the video identification information “V001” is included.

  When receiving the video acquisition instruction from the display control unit 17, the processing unit 16 extracts and acquires corresponding video information from the video information storage unit 13 using the video identification information included in the video acquisition instruction (S102). . In the case of the present embodiment, video information related to the video identification information “V001” is acquired.

  The video information storage unit 13 stores various video information stored in advance for reproduction on the terminal B. The stored video information includes video identification information for uniquely identifying the video, playback time information for the entire video (total playback time information), moving image data information and audio data information included in the video. And An example of the video information stored in the video information storage unit 13 is shown in FIG.

  Next, the processing unit 16 searches the processing data storage unit 15 using the video identification information included in the video information to determine whether there is processing data corresponding to the extracted video information. If there is no processed data as a result of the search, the acquired video information is transmitted to the display control unit 17 as it is (without being processed) (S103).

  In the processed data storage unit 15, processed data indicating which part of the video is to be processed is stored in association with each video identification information. In the stored processing data, video identification information for uniquely identifying the video, an important range indicating an important part of the video, an unnecessary range indicating an unnecessary part of the video, and any processing for each range It is assumed that the processing content indicating whether or not to apply is included. An example of the machining data stored in the machining data storage unit 15 is shown in FIG. In the case of the present embodiment, since there is no processed data of the video identification information “V001” in the processed data storage unit 15, the acquired video information is transmitted to the display control unit 17 as it is without being processed. Become.

  The display control unit 17 transmits the video information acquired from the processing unit 16 to the terminal B via the network I / F 10.

  The display information receiving unit 21 of the terminal B receives the video information from the management server A via the network I / F 20 and transmits it to the terminal control unit 22.

  The terminal control unit 22 reproduces the acquired video information and displays it on the terminal display device 23 or the external display device C (S104).

  A user who views the video on the terminal display device 23 or the external display device C uses the terminal input device 24 or the external input device D to obtain point information regarding a scene that is determined to be important in the video being played back. Enter against.

  The above processing will be specifically described by taking the case of the present embodiment as an example. As described above, when the user is an elementary school teacher and the video to be viewed is a video video (video identification information “V001”) used in the teacher's class, the teacher is viewing the video. In a scene that is determined to be important, the button of the terminal input device 24 (for example, a keyboard) or the button of the external input device D (for example, a remote controller) is pressed. When multiple scenes that can be determined to be important appear in the video being viewed, or when a scene that is determined to be more important appears, the button must be pressed continuously. . There are no particular restrictions on the number and timing of button presses.

  The point information generation unit 25 acquires information input by the terminal input device 24 or the external input device D acquired by the terminal control unit 22, and generates point information. The generated point information includes video identification information for uniquely identifying the video viewed by the user, playback time information indicating the video position at which the user has determined that the user has pressed the button, and the user who has viewed the video. User identification information (or terminal identification information for uniquely identifying a terminal that has output point information) is included at least. An example of the generated point information is shown in FIG.

The point information generation unit 25 further transmits the generated point information to the management server A via the network I / F 20. The point information transmission timing may be a format in which the point information generation unit transmits the point information each time it is generated, or a format in which the point information generated within a predetermined time is transmitted periodically. Also good.

  The point information acquisition unit 11 of the management server A acquires the point information transmitted from the terminal B via the network I / F 10 and stores the acquired point information in the point information storage unit 12 (S105). An example of the point information stored in the point information storage unit 12 is shown in FIG.

  The important range determination unit 14 extracts video information corresponding to the point information stored in the point information storage unit 12 from the video information storage unit 13, and determines an important range in the extracted video information (S106). . Then, the determined important range information is transmitted to the machining data generation unit 15.

  The above processing will be specifically described. A case will be described as an example where point information is stored as shown in FIG. 10 and an important range of video corresponding to video identification information “V001” is determined. First, the important range determination unit 14 extracts video information corresponding to the video identification information “V001” from the video information storage unit 13. Next, a range before and after a predetermined value is calculated around the position (reproduction time information) from which the point information of the video identification information “V001” extracted from the video information storage unit 13 is acquired. The determined range is determined as the important range in the video. Here, the predetermined value is set to “5 minutes before and after”. In this setting, the important ranges are “0:05:20 to 0:15:20”, “0:20:40 to 0:30:40”, “0:37:05 to 0:47:05”. It is determined that there are three. Then, the entire reproduction time “0:55:30” is extracted from the video information corresponding to the video identification information “V001”, and an unnecessary range excluding the important range is determined therefrom. As a result, “00: 00: 00-0: 05: 20”, “0: 15: 20-0: 20: 40”, “0: 30: 40-0: 37: 05”, “0:47: "05 to 0:55:30". The important range determination unit 14 collects information regarding the determined important range and unnecessary range as important range information and transmits the information to the processing data storage unit 15.

  The processing data storage unit 15 generates processing data based on the important range information acquired from the important range determination unit 14, and stores the processing data in association with each video identification information in its own storage area (S107). .

  The above processing will be specifically described. First, the processing data storage unit 15 first has an important range type (referred to here as information for identifying an important range or an unnecessary range) with respect to the important range information acquired from the important range determination unit 14. The contents of the modification table associated with the contents of the modification process are collated to determine what part of the video is to be edited. An example of the processing table used in this case is shown in FIG.

  Next, the processing data storage unit 15 determines the content of the processing according to the important range information, and generates processing data in association with the video identification information. Then, for each video identification information included in the processed data information, the processed data is stored in its own storage area.
