摘要： PROBLEM TO BE SOLVED: To reduce a delay time for displaying a video image after channel change, while preventing disturbance in the video image due to fluctuation of a transmission speed.
SOLUTION: A reception buffer control means 801 avoids impact due to variation in the amount of data accumulated in a receive buffer control means 403 caused by fluctuation of a transmission speed etc., by increasing or decreasing the target amount of a data size and a transfer rate based on two thresholds. Further, the reception buffer control means 801 holds the target amount of the data size at the time of channel change as a transfer initiation size after channel change. According to the arrangement, a delay time for displaying a video image after channel change is reduced.

摘要： PROBLEM TO BE SOLVED: To solve the problem that loss of packets generally occurs in a burst state in a packet communication network and it is highly likely that a plurality of adjacent packets are collectively lost, therefore, both of the duplicated sound packets are lost even if the sound packet is duplicated, and consequently, the sound is distorted. SOLUTION: One of the duplicated sound packets 3, 4 is transmitted by temporally shifting it. Thus, it is unlikely that both of the duplicated packets are lost. Consequently, it is highly likely that sound jumpiness can be avoided by using the other packet when one of the duplicated packets is lost in a receiving device 2A. COPYRIGHT: (C)2007,JPO&INPIT
