Abstract
An apparatus for receiving a digital broadcast signal includes a tuner operable to select a desired transmission channel over which to receive the digital broadcast signal and demodulate a transport stream which is transmitted over the selected transmission channel. The receiving apparatus also includes a demultiplexer operable to extract a desired program from the demodulated transport stream; an interface operable to transmit the demodulated transport stream to, and receive a reproduced transport stream from, a reproducing apparatus; and a discriminator operable to determine whether the reproduced transport stream contains a multiplexed plurality of programs. A predetermined process is performed on the reproduced transport stream when the discriminator determines that the reproduced transport stream contains the multiplexed plurality of programs.
