The processing unit 72 temporarily buffers the moving image data transmitted from the second communication terminal device 10b in the storage unit 74, accepts the moving image request, and determines that the moving image distribution permission is permitted, the moving image request The video is distributed to the original communication terminal device 10 as needed. As described above, the moving image data is distributed via the server device 20.

The moving image receiving unit 316 of the first communication terminal device 10a receives moving image data from the server device 20 through mobile communication. The video reception unit 316 converts the received video data into the video playback unit 318.
Output to. The moving image reproducing unit 318 of the first communication terminal device 10a reproduces the moving image data from the moving image accepting unit 316, and displays the reproduced moving image data on the monitor 38.

Thus, the 1st communication terminal device 10a receives distribution of moving image data by mobile communication based on the 1st information contained in link information. Under such circumstances, selection of the destination of audio transmission and PTT are performed by user operation to transmit audio to the moving image distribution source being viewed.

According to the present embodiment, since the link information about the second communication terminal device is received, when moving image data is received from the second communication terminal device by mobile communication, the second communication terminal device is wirelessly used for business use. When making a call, the wireless CH of the second communication terminal device can be specified based on the second information of the link information. Moreover, since the link information is received in advance, the wireless CH of the second communication terminal device can be automatically specified. In addition, when receiving video data by mobile communication,
Since the wireless CH of the second communication terminal device is automatically specified, it is possible to suppress complication of operation even when a plurality of communication methods are supported. Since the link information is managed in the server device, the processing of the communication terminal device can be simplified.

In addition, since the distribution of the moving image data is performed via the server device, the permission determination can be performed.
Moreover, since permission determination is performed in a server apparatus, the permission determination in a communication terminal device can be made unnecessary. In addition, since the permission determination is executed in the server device, it is possible to ensure the security of distribution. In addition, since the server device temporarily stores and distributes the moving image data, the communication transmitting terminal can make it unnecessary to distribute the moving image data again even when the same moving image data is distributed to a plurality of communication terminal devices. In addition, since the channel operation is performed using information linked to the connection destination of the mobile communication and the wireless CH for business use, the operation load on the user can be reduced.
