Brief description of the multiplexing signals different in nature, brief description of such signals, an interface for the brief of the signals thus multiplexed and the disk, 1984, supporting such signals

摘要

The present invention relates firstly to a multiplexing process of the two digital signals of different nature, for example a signal processing and a digital audio signal - in view of their recording on a digital medium, divided into sectors indexed, the length of the bytes is defined and invariable, that it constitutes the multiframe start time of a total length of m bytes in the three series of frames, the first series s 1 of the frames of the multiframe corresponding to a preamble of the whole of the signals of service, the second series 3 of the frames of k successive channels the digital signals of the first category, and the third series of frames of 5 k successive channels the digital signals of the second category, the total length of the three series of frames being of m bytes, the length of said first series of frames and the length of said second series of frames being multiples of k, m being an integer multiple or half - integer of l. / p & & p & the present invention also relates to a method of decoding digital signals thus multiplexed as well as an interface, and a digital disk comprising the sectors of the digital data thus organized. p / p applications: books speaking and programs of teaching assisted by computer recoverable with the aid of a digital disk player.
