The button color, button size, etc. are determined based on the received user interface data. The GUI 121 on the receiving side has a function of interpreting this user interface data and configuring a display screen.

One embodiment will be described more specifically. FIG. 2 schematically shows a plurality of distributed video and audio. Here, the state of content production by two photographing cameras is shown. C1 shown in FIG. 2A is the video / audio from the photographing camera 1 input from the input terminal 104a, C2 shown in FIG. 2B is the video / audio from the photographing camera 2 input from the input terminal 104b, and CA shown in FIG. 2C is Prior to distribution, the audio and video C is edited in advance by the editor 105
It is a video and audio that edits 1 and C2. In the conventional system, only the edited video / audio CA is transmitted / received. In FIG. 2, 1-1, 1-2, ... Are cuts of the imaged video and audio C1. A cut is a unit of video from an arbitrary time to an arbitrary time. Normally,
It is a unit of video until it switches from continuous video to another continuous video.

Similarly, 2-1, 2-2, ... Are cuts of the imaged audio and video C2. The edited video / audio CA is a result of editing the video / audio C1 and C2. In FIG. 2, as an example, the video / audio C1 and C2 are arbitrarily combined to create the video / audio CA. In reality, the audiovisual creator intentionally edits. When the number of photographing cameras increases, the required cuts are combined and edited into the video / audio CA in the same manner as the video / audio C1 and C2.

The horizontal axis in FIG. 2 shows the elapsed time of the video and audio. However, in FIG. 2, 1-1, 1-2, ...
The lengths of the individual cuts 2-1, 2-2, ... Are shown at equal intervals, but this does not indicate that each cut is of equal time, but simply each cut. It indicates the boundary of. In reality, the length of time is often different for each cut. Further, the vertical axis in FIG. 2 has no particular meaning. For convenience, each cut is shown as a rectangle only.

The video and audio C1 and C2 shown in FIG.
In addition, the edited video / audio CA is distributed and received together with information about each cut (that is, information about where one cut is from one place to another (time change or scene change)). As another method, video / audio C1 and C2
And information about each cut as described above and information indicating the order in which the cuts are connected so that the CA can view (that is, information about the order of the cuts in the edited video / audio CA). . In the former method, some cuts to be transmitted and received overlap, but in the latter method, since the cuts do not overlap, the latter method is more efficient because it can reduce the amount of video and audio distributed and received. I can say. Also, the audio and video that was divided into each cut in advance, and the meaning of each cut,
In other words, it is also possible to distribute index information indicating which shooting camera has taken the cut and what number of the cut it corresponds to. The index information can be described in BML, HTML, XML, etc. described above. In either case, the receiving side is required to have a function of decoding each piece of information.

The distribution device 102 distributes video and audio under the above conditions. FIG. 3 schematically shows a viewing mode after receiving the distributed video and audio. In one embodiment of the present invention, since it is possible to arbitrarily select and view any cut, there are as many viewing modes as there are combinations of the number of cuts, but in FIG. 3, four types of viewing modes are shown as examples. Shows.

FIG. 3A shows a case where the edited video / audio CA shown in FIG. 2C is viewed as it is. 3B, 3C, and 3D show the result of original editing using the GUI 121 on the receiving side. FIG. 3B shows a case where the cuts 1-1 to 1-5 of the video / audio C1 and the cuts 2-6 and after of the video / audio C2 are selectively viewed. FIG. 3C shows a video / audio C.
The case where only 1 is selected and viewed is shown. FIG. 3D shows a case where the respective cuts of the video and audio C1 and the video and audio C2 are alternately selected and viewed. The meaning of the horizontal axis and the vertical axis in FIG.
Is the same as.

In order to enable the viewing mode of FIG. 3, the following user interface is required on the video display screen such as the entire television screen or the entire computer screen. First, an image display unit for displaying the received image and a selection unit for selecting the cut of each video / audio are required. Furthermore, in order to realize a function equivalent to the conventional function, a data operation unit for characters and still images and an operation unit for two-way communication are required. As described above, it can be said that the GUI 121 roughly needs a video display screen having four functions.

Here, as a specific example, a case where the video and audio of a shogi game is distributed and received will be described below. This invention is not limited to Shogi games, but Shogi games
The present invention is suitable for application of the present invention because it has features such as easy cut division, little motion in the image, easy editing of the image, and a large number of users who repeatedly view the image because it is advanced by each move.
