Abstract:
1. An apparatus to transmit communication and broadcasting data, comprising: a mapper to map input communication data into a communication stream according to a predetermined standard; a broadcasting buffer to temporarily store a broadcasting stream for multiplexing; a communication buffer to temporarily store the communication stream for multiplexing; a counter to measure data rate information of the broadcasting stream inputted between two SYNC signals and output the measured data rate; an SYNC signal generator to generate the SYNC signals for synchronization between the transmitting apparatus and a receiving part, and periodically transmit the generated SYNC signals; and a multiplexer to multiplex the communication stream and the broadcasting stream based on the measured data rate to output a transport stream, wherein the transport stream is an MPEG-2 TS, the communication stream is an MPEG-2 TS into which a DOCSIS MAC frame is mapped, and the broadcasting stream in an A/V MPEG-2 TS, wherein the counter includes:
