Description / Abstract:
This International Standard establishes a source-coding
data-compression algorithm applied to digital data and specifies
how these compressed data shall be inserted into source packets for
retrieval and decoding.
Source coding for data compression is a method utilized in data
systems to reduce the volume of digital data to achieve benefits in
areas including, but not limited to,
a) reduction of transmission channel bandwidth;
b) reduction of the buffering and storage requirement;
c) reduction of data-transmission time at a given rate.
The characteristics of source codes are specified only to the
extent necessary to ensure multi-mission support capabilities. This
International Standard does not attempt to quantify the relative
bandwidth reduction, the merits of each approach discussed, or the
design requirements for coders and associated decoders. Some
performance information is included in Lossless Data
Compression, CCSDS 120.0-G-2.
This International Standard addresses only Lossless source
coding, which is applicable to a wide range of digital data, both
imaging and non-imaging, where the requirement is for a moderate
data-rate reduction constrained to allow no distortion to be added
in the data compression/decompression process. The decompression
process is not addressed.
The scope and field of application are furthermore detailed in
subclause 1.3 of the enclosed CCSDS publication.
