<P>PROBLEM TO BE SOLVED: To provide an apparatus and a method for clock signal generation which can generate clock signals for main data reproduction at an accurate frequency in a receiver side, even if burst delays or arrival order inversion occurs in packets transmitted through a network. <P>SOLUTION: A timestamp of a received packet which has a specified sequence number is extracted from received packets as a transmission timestamp, and a timestamp which indicates the receiving time of a received packet that is synchronized with a clock signal, and has a specified sequence number is generated as a receiving timestamp. Then, the frequency of a clock signal is adjusted so that the time intervals between transmission timestamps match to time intervals between receiving timestamps. <P>COPYRIGHT: (C)2008,JPO&INPIT |
