In an attempt to standardise a coding system for the Advanced Display Stream Compression (A-DSC) standard, VESA has issued a Call for Technology (CfT).
The CfT includes requirements that apply to solutions, evaluation criteria and required items to be submitted. VESA intends to standardise a visually lossless compression system for high-bandwidth video, at lower compressed bit rates than are possible with DSC v1.1.
As we wrote back in November, ‘A-DSC is aimed at applications that require a lower bits-per-pixel (bpp) bit rate than DSC v1.1, which provides 8bpp. The visually lossless coding quality will be maintained. In exchange for improved compression, A-DSC will require more complex encoders and decoders. However, complexity will still be lower than HEVC with Screen Content Coding Extensions’ (Display Monitor Vol 21 No 44).
