There are 6 different DSC configuration profiles are supported currently. DSC configuration profiles are differiented by 5 keys, DSC version (V1.1), chroma (444/422/420), colorspace (RGB/YUV), bpc(8/10), bpp (6/7/7.5/8/9/10/12/15) and SCR (0/1). Only DSC version V1.1 added and V1.2 will be added later.
