The CCSDS 122.0-B-1 specification is part of a standards suite developed by the Consultative Committee for Space Data Systems. The CCSDS is formed by the major space agencies of the world for the development of communications and data systems standards for space applications. The CCSDS 122.0-B-1 fits the compression requirement for a wide range of spaceborne two-dimensional spatial image data. In these applications the requirement is for a scalable data reduction, with the option to use lossless or lossy compression, using a memory-efficient and reduced complexity algorithm that results in a fast, low-power and compact hardware implementation.
The CCSDS 122.0-B-1 standard was developed to balance between compression performance and complexity with particular emphasis on spacecraft applications. Compared to JPEG 2000, it achieves slightly lower, but essentially similar, lossless and lossy compression efficiency. Due to its reduced complexity, it requires significantly less silicon logic area, along with reduced amount of internal memories, and achieves higher throughput. The Alma Technologies CCSDS 122.0-B-1 encoder realizes all these expected benefits, while also not needing an external memory device for its implementation.
