Abstract

Transmission of a transport stream to an external device is effectively performed in the present invention. A transport stream including in a time multiplexed manner PID data packets for a plurality of service channels is inputted. A time stamp corresponding to the inputted time is applied to PID packets remaining after the PID data packets are removed from the service channels selected (tuned) for the transport stream. The PID packets to which the time stamp is applied are sequentially transmitted to an external device. The transmission bit rate can be kept low. The PID packets returned from the external device are returned to their original time positions in accordance with the time stamp allowing simple reconfiguration of the transport stream.
