Developing Requirements for a Visually Lossless Display Stream Coding System Open Standard

摘要

The Video Electronics Standards Association (VESA) is developing a standard for a visually lossless coding system to be used for the compression of high-bandwidth display data streams. This coding system will complement digital display interface technologies to increase pixel rates or save system power, or both. The display stream coding system is primarily being designed to meet the increased pixel rate needed in high-resolution displays expected in the next few years. This paper recounts VESA’s process that led to compression requirements, the selection of a coding system baseline, and strategies to evaluate a visually lossless coding system for consumer electronics and commercial displays. Key concepts in this paper evolved from discussions and documents of VESA’s Display Stream Compression Task Group that have been made available to the author with permission from VESA. The first version of the Display Stream Compression Standard was published on 1 August 2014.
