Data Compression Data compression standards revolve around the applicability and use of various algorithms for lossy and lossless data compression. With modern technology providing ever more information, such as higher quality image data, video recording, and so forth, data compression must be sufficiently advanced to manage this amount of information. Following that, interoperability points toward standardization for widespread data compression techniques and methods. Chief among other benefits, data compressions touts a "reduction of transmission channel bandwidth; reduction of the buffering and storage requirement; reduction of data-transmission time at a given rate."

ISO 15887:2013

Space data and information transfer systems - Lossless data compression

ISO 15887:2013 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: reduction of transmission channel bandwidth; reduction of the buffering and storage requirement; 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. ISO 15887:2013 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 CCSDS 120.0-G-2. ISO 15887:2013 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.

ISO 18381:2013

Space data and information transfer systems - Lossless multispectral and hyperspectral image compression

ISO 18381:2013 establishes a data compression algorithm applied to digital three-dimensional image data from payload instruments, such as multispectral and hyperspectral imagers, and specifies the compressed data format. Data compression is used to reduce the volume of digital data to achieve benefits in areas including, but not limited to: reduction of transmission channel bandwidth; reduction of the buffering and storage requirement; reduction of data-transmission time at a given rate. The characteristics of instrument data are specified only to the extent necessary to ensure multi-mission support capabilities. ISO 18381:2013 does not attempt to quantify the relative bandwidth reduction, the merits of the approaches discussed, or the design requirements for encoders and associated decoders. ISO 18381:2013 addresses only lossless compression of three-dimensional data, where the requirement is for a data-rate reduction constrained to allow no distortion to be added in the data compression/decompression process.

ISO 26868:2009

Space data and information transfer systems - Image data compression

ISO 26868:2009 establishes a data compression algorithm applicable to two-dimensional digital spatial image data from payload instruments and specifies how this compressed data is formatted into segments to enable decompression at the receiving end. 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: reduction of transmission channel bandwidth; reduction of the buffering and storage requirement; reduction of data-transmission time at a given rate.

IEC 62356-2 Ed. 1.0 b:2003

"Video recording - 12,65 mm Type D-11 format - Part 2: Picture compression and data stream"

"IEC 62356-2:2011 specifies the compression of a high-definition source format to a dual-channel packetized data stream format which is suitable for recording on disc and tape storage devices including the Type D-11 tape recorder. The specification includes a number of basic packetizing operations including the shuffling of the source data prior to compression, both to aid compression performance and to allow error concealment processing in the decoder. The standard also includes the processes required to decode the compressed Type D-11 packetized data format into a high-definition output signal. This bilingual version, published in 2011-05, corresponds to the English version. It includes corrigendum 1 (2011-05) to the English version. The French version of this standard has not been voted upon."
