Abstract:
A receiving apparatus for a digital broadcast signal, comprising: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 said selected transmission channel; a demultiplexer operable to extract a desired program from said demodulated transport stream; an interface operable to transmit said demodulated transport stream to, and receive a reproduced transport stream from, a reproducing apparatus; and a discriminator operable to determine whether said reproduced transport stream from said reproducing apparatus contains a multiplexed plurality of programs, and said demultiplexer being incapable of extracting a user selected one of said multiplexed plurality of programs from said reproduced transport stream, wherein a predetermined process of program selection is performed on said reproduced transport stream to automatically select only one of said multiplexed plurality of programs when said discriminator determines that said reproduced transport stream contains said multiplexed plurality of programs.
