<P>PROBLEM TO BE SOLVED: To provide a packet communication system and a data receiver capable of reducing difference in delay time between voice packets and video image packets, while maintaining audio quality. <P>SOLUTION: The packet communication system comprises a data transmitter and a data receiver. The data receiver comprises an accumulation amount detection means, an information amount calculation means, an information amount determination means, and an information amount determination means. The accumulation amount detection means detects the amount of video image packets accumulated in a video image jitter buffer. The information amount calculation means calculates the amount of information of voice packets. The information amount determination means determines whether the amount of information calculated by the information amount calculation means is below a predetermined value or not. A reproduction control means changes a reproduction time duration for the voice packets determined as the ones below the predetermined value by the information amount determination means, according to the amount of video image packets detected by the accumulation amount detection means. <P>COPYRIGHT: (C)2008,JPO&INPIT |
