VIDEOPHONE SYSTEM, SELF-SUPPORT BASE STATION DEVICE, SET TOP BOX, AND VIDEOPHONE METHOD

摘要

a mobile communication terminal (90u) having a function for transmitting/receiving imaged moving picture to/from a radio communication base station and performing communication; and a monitor device (44) for displaying a moving picture transmitted/received to/from a radio communication base station (3B) by using a communication protocol between the radio communication base station (3B) and the mobile communication terminal (90u). Thus, it is possible to perform high-image-quality videophone communication by using a camera arranged at a mobile communication terminal such as a mobile telephone, PHS, and PDA.
