The first controller 12 decodes the encoded second video data, and sends the decoded second video data to the display screen 14 for display, so that the monitoring terminal 500 displays that the mobile communication terminal 100 and the videophone 300 pass through the gateway 200 The transmitted first video data and second video data. Here, the second video data can be encoded or decoded by using various existing encoding methods and decoding methods, and the content of this part will not be repeated in the present invention.

In addition, the mobile communication terminal 100 and the videophone 300 transmit voice data as well as video data via the gateway 200, and the voice data may include first voice data and second voice data.
