METHOD FOR MULTIPLEXING DIGITAL SIGNALS OF A DIFFERENT NATURE, METHOD FOR DECODING SUCH SIGNALS, INTERFACE FOR DECODING SIGNALS THUS MULTIPLEXES AND DIGITAL DISK SUPPORTING SUCH SIGNALS

摘要

The present invention firstly relates to a method of multiplexing two digital signals of different nature, for example a computer signal and an audio-digital signal for recording on a digital medium, organized in indexed sectors whose length of L bytes is defined and invariable, that multiframes of a total length of M bytes organized in three series of frames are constituted, the first series 1 of the frames of said multiframe corresponding to a preamble gathering all the service signals , the second series 3 of frames grouping in K successive channels the digital signals of the first category, and the third series of frames grouping in K successive channels the digital signals of the second category, the cumulative length of the three series of frames being M bytes, the length of said first series of frames and the length of said second series of frames being mu multiples of K, where M is an integer or half-integer multiple of L. / P P The present invention also relates to a method of decoding digital signals thus multiplexed as well as a decoding interface and a digital disc comprising digital data sectors organized in this way. / P P Applications: talking books and computer-assisted learning programs that can be retrieved using a standard digital disc player. / P
