Method for coding integer supporting diverse frame sizes and codec implementing the method

摘要

An integer coding method supporting diverse frame sizes and a coder-decoder (CODEC) implementing the method are provided. Maximum sample values are detected from a plurality of frames having different numbers of samples. The detected maximum sample values are normalized on the basis of a maximum sample value of the largest frame. A maximum sample value is detected from the normalized sample values. Multiples are determined according to the size of each frame on the basis of the detected maximum sample value and a sample value of each frame is multiplied by the multiples to generate an integer code.
