1. A digital broadcasting signal receiving apparatus comprising:

  • a channel decoding circuit receiving transmitted digital information and demodulating the received digital information into a bit stream having a predetermined packet structure, said transmitted digital information being such that a plurality of logical channel signals constituted by video, audio, and data are multiplexed as digital information on a single bit stream having a predetermined packet format and are transmitted;

    a first packet separating circuit extracting a designated packet from a bit stream outputted from said channel decoding circuit;

    a source decoding circuit decoding a logical channel signal outputted from said first packet separating circuit to output the decoded logical channel as a television signal;

    a second packet separating circuit extracting at least a portion of the designated packets from the bit stream outputted from said channel decoding circuit;

    an output circuit outputting a bit stream outputted from said second packet separating circuit toward a recording/reproducing circuit;

    an input circuit supplying a bit stream derived from said recording/reproducing circuit to said first packet separating circuit; and

    a control circuit controlling operations of said first packet separating circuit and said second packet separating circuit.
