ABSTRACT:
An improved digital signal processor is provided, and includes a tuner for selecting a single transport stream containing a plurality of multiplexed channels from a plurality of transmitted transport streams, a demultiplexer for separating video data and audio data corresponding to a single program contained in the selected transport stream by referring to supplementary data in the selected transport stream, a decoder for decoding the separated video and audio data, an input connected to an external device for receiving video data, audio data and supplementary data from the external device, and for sending video data, audio data and supplementary data to the demultiplexer, and a controller for receiving a program discontinuity data contained in the supplementary data received from the external device, and initializing the decoder in response to the program discontinuity data. A method of applying the digital signal processor is also provided.
