Title:
COMPRESSION ENCODING DEVICE AND METHOD, DECODING DEVICE AND METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/203976
Kind Code:
A1
Abstract:
The present disclosure pertains to a compression encoding device and method, a decoding device and method, and a program, which enable provision of lossless compression technique at a higher compression rate. According to the present invention, a GOB data configuration unit configures GOB data with one group of digital data formed of a plurality of blocks, in which single frame of delta-sigma modulated digital data is set as a single block. A table generation unit generates a conversion table for encoding the GOB data. An encoding unit performs compression encoding of the digital data of each block forming the GOB data by using the conversion table. This technique can be applied to, for example, compression encoding of audio signals, etc.
