CONSTITUTION: A demultiplexer receives an MPEG-2 transport stream data from a dialogue type broadcasting terminal system and divides the data for each content. Several first storing units temporarily store the demultiplexed data. A processor processes the user's requirement for the contents. Several processor/decoders process and decode the demultiplexed data. Several second storing units temporarily store the processed and decoded data. A controller controls the decoding process and performs re-writing if there is a change in the data stored in the second storing units. A video synthesis/output unit synthesizes and outputs a video image by receiving the data stored in the second storing units. An audio output unit receives an audio data stored in the second storing units.
