1. method that is used for the embedding encode of signal may further comprise the steps:

  • The input signal of encode is treated in reception;

    Described input signal is carried out encode, to produce the encode sound signal;

    Utilize a plurality of yield values that described encode sound signal is regulated to produce a plurality of adjusting encode sound signals, each is regulated the encode sound signal and has related yield value;

    Determine a plurality of error amounts based on each the adjusting encode sound signal in described input signal and the described a plurality of adjusting encode sound signal;

    From described a plurality of yield values, select yield value;

    AndWith described yield value as the part of the enhancement layer of described encode sound signal being launched or storing.
