1. the multi-channel digital audio information recording that will have the tentation data bit rate is in the method for permanent stored digital media, and it comprises:

  • The permanent stored digital media (12) that can store digital audio and video signals is provided, and wherein digital audio and video signals is received with predetermined format and with the speed that is no more than predetermined maximum data bit rate by this storage medium;

    Provide the multichannel input digital audio signal (CH1, CH2 ... CHn), its data splitting bit rate surpasses this maximum data bit rate;

    Compression (C1, C2 ... Cn) data bit-rate of this multichannel input digital audio signal is so that the data splitting bit rate after its compression is no more than the maximum data bit rate of storage medium;

    Multichannel modulation (2) this compression digital audio frequency signal makes it to become the multichannel modulation signal (32) with the bit rate that is no more than storage medium maximum data bit rate;

    Coding (6) this multichannel modulation signal makes it to have this predetermined format;

    This code signal is write down (10) on this stored digital media.
