In a video communication device comprising an input / output device and a video communication network control device for inputting / outputting encoded video information via an external communication network, when the video to be transferred is stored in the video storage / playback device, Means for recording and storing video transfer destination information as well as recording and storing the video transfer destination information, and video and video transfer destination information from the video storage and playback device are encoded as video information by the video input / output device, and through the video communication network control device. It has means for adding transfer source information and connecting to a transfer destination of an external communication network to transfer the video information and the transfer source information.

Further, when the video communication network control device receives a connection request from the external communication network, the transfer source information of the received video information is recorded in the video storage / reproduction device by the video input / output device and the video input / output device is input. It is stored together with the video decoded by the output device.

The video transfer destination information is transferred to a plurality of transfer destinations by recording a plurality of the transfer destination information when the video transfer is performed.

[0009]

[Operation] The transfer destination information is recorded together with the video to be transferred, encoded by the video input / output device as the video information, and the communication network control device automatically selects the transfer destination to be connected according to the transfer destination information of the video information. And the transfer source information is transferred to the transfer destination together with the video. At the transfer destination, connected by the transfer destination information, the video input / output device decodes this as a video and stores it in the video storage / playback device, and also records the transfer source information.

[0010]

FIG. 1 shows an embodiment of the present invention.

Here, a VTR is used as a video storage / reproduction device.
However, it goes without saying that a real-time or non-real-time video storage / reproduction device other than the VTR can be used. The video transfer communication device 1 includes a video input / output device 11 and a communication network control device 12.

First, video is stored in the VTR 2. For example, the beginning part of the image (here, the beginning part of the image is taken as an example, but if it is an image, the transfer destination information is recorded in a blanking area or the like, for example. It goes without saying that the transfer destination information is recorded.

The video input / output device 11 encodes the video and transfer destination information as video information, outputs the video information to the communication network control device 12, and instructs the transfer destination. The communication network control device 12 instructed to the transfer destination adds the transfer source information and transmits it together with the video information to the transfer destination connected through the communication network.

Next, at the transmission destination, the communication network control device 12, which has received the connection instruction from the communication network, gives the video information received after the connection to the video input / output device 11. After that, when decoding the video information transferred from the communication network, this transfer source information is added as a video and recorded in the VTR 2. Here, an example is shown in which the transfer source information is recorded at the beginning of the video, but it goes without saying that other video areas can be used as described above. Next, as shown in FIG. 2, the transfer destination information is recorded as a plurality of videos. The video input / output device 11 that has received this video instructs the communication network through the communication network control device 12 to transfer the same video information to a plurality of destinations. As a result, one video transfer communication device 1
It is possible to broadcast from multiple destinations.

Regarding the transfer destination / transfer source encoding method, it goes without saying that a telephone number or the like in the existing communication network can be used and other user information can be added.
