Title:
DATA COMPRESSION
Document Type and Number:
WIPO Patent Application WO/2016/160242
Kind Code:
A3
Abstract:
Data compression is described herein. The encoder transmits a coded word having replacement bits, as well as a code that defines the starting location of the replacement bits in a data sample. The replacement bits may be actual bits from a selected location in the new data sample. The selected location of the replacement bits can vary from data sample to data sample. The encoder may select the location based on the most significant bit that has changed. Thus, reconstructed data will be bit?accurate from the replaced bits all the way to the highest-order bit. A limited number of key values can be transmitted losslessly. Moreover, the data compression does not need forward error correction (FEC), which is a necessary part of many lossy delta encoding schemes. Furthermore, the encoding and decoding can be done very efficiently in terms of hardware and/or software.
