CONSTITUTION:An editor attaches the managing codes of the content and length of a sketch on the forefront of receiving sketch video software as headers, and also, attaches a time code on the video at need. The editor informs header information of the video software desired by the viewer side to the audio visual device 200. The audio visual device 200 records the video software having the managing code in accordance with the header information out of the video software sent from an editing device 100 on an accumulation medium. The editing device 100 sends an edit list to the audio visual device 200 according to the request of the viewer side. In such a way, it is possible to view the content desired by the viewer side fitting in the intention of the editor by reproducing the video software.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] This invention allows a viewer in a remote location to re-edit the video software according to the editor's intention using a large number of video software transmitted using communication means. This relates to a video editing method for viewing and viewing videos.

[Prior art] There are many video sources, such as television programs, and they are overflowing with information. However, these videos are video software aimed at an unspecified number of viewers, and there are many video sources that are of personal interest. In order to view software, there is a problem in that a large amount of information that is not necessary to be viewed must be included. In other words, if you want to concentrate on watching video software that you are personally interested in, you can record all the related video software using a video tape recorder, etc., then fast-forward the tape to the scene that is estimated to be necessary, and then watch that part. The most common method is to watch.

[Problem to be Solved by the Invention 1] However, this method requires complicated operations and does not necessarily allow viewing of desired content. Therefore, there is a limit to the amount of effort one can make to view and listen to the necessary information every day.

Under these circumstances, it is possible for a large number of viewers to watch videos with content according to each person's wishes as an organized series of content at a relatively low cost, and to watch the desired content when they want to see it. A new system is required.

This invention has been made to solve the above problems, and its purpose is to allow a large number of viewers to edit their desired video and provide the content efficiently and in an easy-to-see format.

[Means for Solving the Problems] In the present invention, first, a plurality of viewers convey their requests for videos they want to see to an editor. Next, the editor uses an editing device to break down the series of video software into short video software, adds management code information to each video software to classify it, and sends the video to the viewing devices of all viewers. Send the software. The video software received by the viewing device randomly includes video software that it desires and video software that it does not want, but from among these, only the video software with the content instructed by the editing device is recorded on the storage medium, and other video software is recorded. Do not record the software (. If you do this, only the short video software that you need will be recorded on the storage medium. At this time, if the viewer wants multiple types of video and the video is randomly When recorded, the recorded information must be organized and viewed before viewing, otherwise the information will become inconsistent.For this reason, the editing device uses an editing system that instructs the viewer to view the video software at the desired timing and in what order. When the list is transmitted through communication means and the viewing device plays the video software according to the list, it becomes possible to view the video as intended by the editor.

[Operation] The video editing method using communication means of the present invention selects and records video that matches the editor's intention from among a large number of video software, and records video software that excludes unnecessary information. , a limited capacity storage medium can be used effectively. Furthermore, since the present invention transmits video software with the same content to a large number of viewers, compared to the case where specific video software is transmitted to individual viewers, the video software is transferred depending on the number of viewing requesters. There is little variation in the amount, making it possible to provide a service that satisfies the individual wishes of many viewers.

In addition, since the viewer records only the necessary video software from among a large number of video software, they can obtain video software that fully reflects their individual wishes, and even among the video software obtained, they can record only the video software they need at the time. Since video software can be selected according to the user's needs and the viewing order and scope of each video software can be limited, the viewer can create a story and view only video software with specific content according to the editor's intention. In addition, the viewing side requires a recording means such as a video disc device, a means with a simple computer function to control it, and relatively inexpensive manual equipment such as a television receiver and communication means. It is only necessary;
The financial burden can be reduced.

Information can be exchanged with other devices via 1. Further, the communication controller 15 can control input and output by the main controller 1.

Note that 16 to 19 indicate each channel.

FIG. 2 shows the configuration of a viewing device 200 held by a user. This configuration is similar to the configuration of the editing device 100, but does not require devices related to editing. Therefore, the editing information creator 4. TV camera 12, color scanner 13. This configuration does not include a time code generator 6 and a microphone 14. Here, the personal computer can serve as the main controller 1, the keyboard 2, and the management information memory 5.

Next, in order to make it easier to understand how to use this device, a specific example will be explained.

For example, broadcast news programs include politics and economics.

It contains news about society, sports, etc., but the center of interest varies depending on the individual. However, since news programs are scheduled for the general public, the news is broadcast comprehensively, and you don't know when the content you are most interested in will be broadcast, so you have to watch news that you are not interested in. It won't happen. In addition, in the case of news where it is important to understand the progress of the content in order to grasp the whole story, the depth of understanding of the content differs depending on the viewing of past important news.

Under these circumstances, when a specific person is interested in specific news, by re-editing previously reported news to suit the individual's wishes, they can read in-depth news in a short time at their convenience. You will be able to watch it on. This invention makes this possible, and a specific example of this will be explained using the case of a viewer who is interested in economics and baseball in the news.

Viewers communicate their interests and specific wishes to the editor. The editor first adds a management code such as the content and length of the short film as a header to the beginning of the short video software obtained using the device shown in Figure 1, and also adds a time code to the video as necessary. Add. A large number of video software processed in this manner is transmitted to a plurality of viewing devices 200 via wired communication 10 or wireless communication 11. Prior to this, the editor notifies the viewing device 200 of header information possessed by the video software corresponding to the content desired by the viewer. The viewing device 200 that has received this transmits the editing device 10.
The viewing device 200 in FIG. 2 searches for video software that has a management code that matches the header information notified first from among the video software sent from 0, and only when the video with that header information comes, the video software is displayed. Recording is performed on a storage medium using a tape recorder 7, an optical disk device 8, or the like. After that, it waits until the next video software with the corresponding header information arrives.

In this example, the viewer obtains video software related to economics and baseball from among a large number of video software, and a plurality of various video software related to economics and baseball are randomly recorded on the storage medium. In this state, if you watch the video software from the beginning, the economics and baseball videos will be randomly swapped, and the relationship over time will also be inconsistent. Therefore, the editing device 10
0 sends to the viewing device 200 an edit list that specifies the viewing order of the video software sent so far and the viewing range of each video software, etc., in accordance with the request from the viewing side. By reproducing the software, the viewer can view the desired content in accordance with the editor's intention.

Flowcharts showing these relationships are shown in FIGS. 3 and 4.

FIG. 3 shows the process flow after the viewing side has informed the editor of its wishes and the editing device 100 has notified the viewing device 200 of the management code of the video software to be recorded. Note that +11 to (12) indicate each step.

The editing device 100 collects video sources (fl) and adds a management code and, if necessary, a time code to each video source (2). Next, use these to create an edited story according to the viewer's requirements (3), create additional video scenes with missing titles, charts, and videos (4),
Add the management code and time code to this as well (5).

An edit list indicating the viewing order and viewing length of these videos is created (6), and the videos are transferred to the viewing device 200 (9).

When new video software is added as time passes, the edit story and edit list are created again (7), and new video software that has not been transferred to the viewing device 200 is sequentially transmitted via communication means ( 8),
(91 When the viewing device 200 receives the video software (10), it determines whether the video should be recorded based on the header information by comparing it with the management code notified in advance 11)
The necessary video software is sequentially recorded (12). These tasks are the tasks that computers are best at, and it goes without saying that they can be performed automatically.

FIG. 4 is a flow chart of the process when the viewing device 200 plays back video software according to the editor's intention. (21)～
(35) indicates each step.

First, when a new edit list is created (21), the editing device 100 constantly updates the list to a new edit list (22) to keep up with ever-changing information. on the other hand,
When the viewing device 200 requests an edit list (23), the editing device 100 responds by transmitting the edit list to the viewing side (24).

After receiving this, the viewing side starts the editing list program on the main controller 1 (25) to (27), and selects the type of video to be viewed from the menu (28). Viewing device 20
0 reads the video list according to the menu selection (29
), and accordingly the video software reproduces the video in the order and length instructed by the editing device 100 (30) to (35).

Up to this point, the explanation has been made on the premise that the viewing side always records the video sent by the editing side, but in reality, recording may not be possible for some reason.

There are two ways to deal with this problem: the editing device 100 sends the same video software several times and only needs to record it once, and the viewing device 200 sends the same video software several times and records only once. There is a method in which the editing device 100 is notified of the list, and the editing device 100 determines which videos are missing from the list and sends them again. This latter step is illustrated in the flow diagram of FIG. In addition,
(41) to (50) indicate each step.

When the viewing device 200 requests the editing device 100 to confirm the missing video (41), the editing device 100 requests a list of management codes of videos recorded and stored by the viewing device 200 (42).

Next, the viewing device 200 transmits the management code of the video software that it has stored to the editing device 100 (43).
The editing device 100 searches for missing video software (44) and transmits the contents to the viewing device 200 (45). In parallel with this, the missing video is retransmitted by communication means (46),
(47). On the other hand, when the viewing device 200 receives a video with a necessary video management code, it determines it based on the management code (48), records the video (49), and when all the missing videos have been recorded (50). , this process ends. Such requests are received from a large number of viewers and must be handled one by one, so a large number of videos are randomly retransmitted. Therefore, the viewing device 200 selects the necessary video from the retransmitted video software and records it (47) to (50). At this time, there is a channel that regularly transmits video software and a channel that transmits missing video.
Separating the separate channels 16 and 17 and 1st and 19 shown in Figures 1 and 2 eliminates the delay in delivering missing video due to waiting for free time on channels that regularly transmit video software (for example, 16 and 18). This makes it possible for the viewer to quickly view the video according to the edit list.

In addition, by using this method of retransmitting the missing video, the viewer can obtain video software that could not be recorded while using the same communication method for other purposes. If there is a communication means that can be used jointly with other communication devices, the video software used in the present invention can be transferred using the free time, and the communication means can be used effectively.

[Effect of the invention 1 As explained above, the present invention adds a management code to each of a plurality of video software, and then transmits all of the video software to a plurality of viewing sides via a communication means, and each viewing side selectively records video software that has a predetermined management code from among the video software that has been created, and plays the recorded video software that was created using the management code and according to an edit list specified for each viewer. This allows editors to re-edit their own video software to meet the needs of many viewers, allowing viewers to view video in accordance with their personal wishes. moreover,
The editor only has to create an edit list, transfer the same video software to a large number of viewers, and respond to requests for the edit list from the viewers. It has the advantage of being compatible with Furthermore, since the video software is transferred to the viewing side in advance, it is not necessarily necessary to transfer the video in real time, but it is possible to transfer the video at a speed slower or faster than real time, and the types of communication methods available You can freely select the transfer speed.

Furthermore, if the editing list using the transferred video is transmitted at the time the viewing side requests it, the editing list basically has a small amount of data, so the transmission will be completed in a short time. The difference in the time you can watch is very short (
, it is possible to give the viewer the feeling that they can see the image immediately. This is possible because the video software is stored using the storage media owned by the viewing side, and if this method uses the storage media owned by the editing side, even if the transmission path is high-speed, the storage media can be stored in large numbers. Because it is used jointly by the viewer, if there are many viewers using it, a phenomenon such as concentration of use of a particular video may occur, and it is not always possible to view the video immediately, and there may be some waiting time between each video software. However, this invention has the feature of being able to prevent this problem.

Furthermore, since the retransmission channel is separate from the channel that regularly transmits video software to a plurality of viewing sides, missing video software on the viewing side can be quickly transferred, which has the advantage of shortening the waiting time on the viewing side.

Furthermore, by having this function, it is possible to provide services that utilize the idle time of the communication means by sharing the communication means with other communication devices.
