ABSTRACT:
A digital data coding/decoding method and apparatus are provided. The coding method includes the steps of representing respective digital data by digits of a predetermined same number, and coding the digital data represented by digits of the same number by a predetermined coding method from the uppermost significant digit sequence to the least significant digit sequence. The method for decoding digital data coded in the order of significance by rating the significance of digits of the digital data, includes the steps of analyzing significance of coded digital data, and decoding the analyzed digital data from upper significant digits to lower significant digits by a predetermined decoding method. Even if some bitstreams are lost or damaged by coding important information first, deterioration in audio quality can be reduced.
