1. In a receiver for processing recorded or transmitted audio, video and data program signal components, wherein respective program signal components occur in signal packets including a signal payload and a service channel identifier, SCID, with different components having different SCID'"'"'s, apparatus comprising:

  • a source of signal including said program signal components;

    SCID detection means, responsive to said signal, for determining SCID'"'"'s associated with respective components of respective programs;

    a plurality of signal processors including an audio signal processor, a video signal processor, and a-data signal processor,a plurality of programmable matched filters, coupled to said source, and which are selectively programmed with signal component SCID'"'"'s, respective said programmable matched filters for detecting signal packets occurring in said signal, which contain SCID'"'"'s identical to a SCID with which it is programmed, for applying corresponding detected signal program components to an associated signal processor; and

    means coupled to said SCID detection means for programming said plurality of programmable matched filters with SCID'"'"'s, associated with a desired program.
