DIGITAL BROADCAST SIGNAL MULTIPLEX TRANSMISSION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a transmission apparatus capable of efficiently multiplexing a data broadcast packet on a television broadcast signal and transmitting the resulting signal at an optional transmission rate in response to fluctuations in an amount of packets of the television broadcast signal. SOLUTION: A data broadcast transmission section 15 inserts a rate information packet describing an optional upper limit rate by each data broadcast program between data broadcast packets and gives the resulting packets to a multiplexer 13, and the multiplexer 13 multiplexes the data broadcast packets on the television broadcast signal at an upper limit rate described in the rate information packet without being affected by band variations in television broadcasting and transmits the resulting packet.
