Verlustfreies Kodierungs- und Dekodierungssystem

摘要

A lossless encoding apparatus encodes audio data and a lossless decoding apparatus restores the losslessly compression encoded audio data on a real-time basis. The lossless encoding apparatus includes a lossless compression unit (13) for losslessly compression encoding the audio data stored in an input buffer (11) in units of predetermined data and outputting the encoded data in sequence, and an output buffer (15) for storing the encoded audio data output from the lossless compression unit (13). A bitrate controller (17) divides a plurality of the encoded audio data stored in the output buffer. (15) into first data having a data amount exceeding.the maximum bitrate and second data having a data amount less than the maximum bitrate, divides the first data 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 over the maximum bitrate and controls the output buffer (15) so that the fourth data is output at the same time when the second data is output. <IMAGE>
