1. A method of generating a digital data stream including program data information and program selection information for transmission, comprising the steps of:

  • producing a plurality of digital program data signals, each of which corresponds to the contents of a program selection;

    producing a plurality of digital program selection signals, each of which corresponds to one of said program data signals and describes the attributes of the associated program selection;

    encoding the plurality of digital program data signals with the plurality of digital program selection signals into a plurality of digital combined signals, each of said combined digital signals being arranged in blocks of a predetermined number of bits of a program data signal and a predetermined number of bits of an associated program selection signal, whereby each program selection signal remains associated with its corresponding program data signal during transmissions therewith; and

    multiplexing the plurality of digital combined signals into the data stream.
