Constant bitrate real-time lossless audio decoding method restoring moved excess coded data amounts

摘要

A lossless decoding method that restores losslessly compression encoded audio data on a real-time basis. The encoded audio data is divided into first data having a data amount exceeding the maximum bitrate and second data having a data amount less than the maximum bitrate, where the first data is divided into third data being the encoded audio data having a data amount of the maximum bitrate and fourth data being the encoded data of the portion exceeding the maximum bitrate, and where the encoded audio data is output so that the fourth data is output together with the second data. The method includes buffering the fourth data in a buffer, combining the buffered fourth data with the corresponding third data, and outputting the combined third and fourth data as restored audio data.
