METHOD AND DEVICE FOR SIGNAL DELIVERY

摘要

PROBLEM TO BE SOLVED: To switch a TS, without causing a transient and characteristic degradation. SOLUTION: A TS packet of a PSI and PCR packet is generated by an encoding part 50 while synchronizing with a reference signal generated with a reference signal generating circuit 201 for STC, or a reference signal generating circuit for picture sequence. Encoding of a signal of a video, a voice, etc., and formation of a packet are performed, and the TS for changeover multiplexed with the packet is generated. When performing the stream changeover in TS changeover part 60, the encoding part 50 is controlled by the control part 40 so that the stream which has information is not delivered, and the quantity of encoded information and the quantity of deliveries of the packet are controlled. Besides, the timing of the delivery of the PCR packet, etc., is controlled. Besides, the same processing is synchronously performed also in a plurality of encoding parts. When performing the changeover of the TS for changeover in a TS changeover part 60 to generate one TS for output, neither the transient nor the characteristic degradation is caused in the TS for output.
