<P>PROBLEM TO BE SOLVED: To provide a reception apparatus, communication system, reception method, and program therefor in which packets on multiplexed channels can be surely synchronized at a reception side by absorbing network delay oscillation to a maximum. <P>SOLUTION: A reception apparatus 60 comprises a time stamp correction section 51 for estimating a PCR of a packet which does not contain a PCR originally. Thus, even when a packet to be received by the reception apparatus 60 does not contain a PCR, the packet can be synchronized while reducing jitter by referring to its estimated PCR. Namely, PCRs of all packets can be obtained and dozens of thousands or ten thousands of PCRs can be obtained within 1s, for example. Thus, synchronism can be established as early possible. Furthermore, since it is not necessary to transmit a PCR for each packet, network bands to be used can be saved. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
