US 2006/0133398 A1 · Apparatus for transmitting/receiving communication and broadcasting data using multiplexing at transmission convergence layer

Abstract

Provided is an apparatus for transmitting/receiving communication and broadcasting data. The transmitting apparatus includes: a mapper for mapping inputted broadcasting data into a transport stream according to a predetermined standard; a broadcasting buffer for temporarily storing the mapped transport stream for multiplexing; a communication buffer for temporarily storing a communication data stream for multiplexing; a counter for measuring data rate information of a broadcasting stream inputted between two SYNC signals and outputting the measured data rate; an SYNC signal generator for generating an SYNC signal for synchronization between the transmitting apparatus and a receiving part and periodically transmitting the generated SYNC signal; and a multiplexer for multiplexing a communication stream, a broadcasting stream, and an SYNC signal.

An apparatus for receiving communication and broadcasting data, comprising:

a splitter for dividing an inputted MPEG-2 TS into a DOCSIS MPEG-2 TS and other streams according to a predetermined process and sequentially outputting the resulting streams;
an MPEG-2 TS decapsulator for extracting a DOCSIS MAC frame from the MPEG-2 TS stream;
an SYNC detector for outputting a timing data for generating a DOCSIS reference clock when the extracted DOCSIS MAC frame is a SYNC message and outputting data rate information contained in the SYNC message;
a data rate controller for controlling an output data rate on the basis of the data rate information;
a buffer for temporarily storing an A/V MPEG-2 TS received from the splitter and outputting the MPEG-2 TS to a decoder under the control of the data rate controller;
and
a decoder for decoding the MPEG-2 TS received from the buffer.
