DIGITAL TRANSMISSION AND RECEPTION DEVICES FOR TRANSMITTING AND RECEIVING STREAMS, AND PROCESSING METHODS THEREOF

摘要

A transmission system is provided which transmits a transport stream (TS) having normal data and additional data. The transmission system includes a stream constructor which generates a TS, and a multiplexer (MUX) which causes mode information representing the characteristics of additional data to be contained in the TS. Therefore, it is possible for a reception system to use the additional data efficiently.
