<P>PROBLEM TO BE SOLVED: To provide a video telephone system where a video is quickly displayed in the case of speech or in the case of reproducing recorded speech. <P>SOLUTION: When signaling processing for establishing a session with a video telephone system 1B is finished at a time t2, a video telephone system 1A starts transmission of video data to the video telephone system 1B. In this case, the video telephone system 1A shortens a transmission interval between intraframes in a fixed period after establishing the session (a period from a time t3 to a time t5). Thus, even when the intraframe disappears at the time t3 by a traffic load of a network, the side of the video telephone system 1B soon receives the intraframe transmitted form the video telephone system 1A at a time t4, and can quickly display the video from the video telephone system 1A with the received intraframe as a key. <P>COPYRIGHT: (C)2011,JPO&INPIT |
