The Display Stream Compression standard is particularly aimed for smartphones and tablets since its introduction in 2014 while with DSC 1.2 it will become more prevalent to notebooks, PC monitors, and televisions. In particular, DisplayPort 1.4 is expected to make use of DSC 1.2. DSC is designed for visually lossless compression of ultra-HD displays and designed to yield vendors lower product costs, greater battery life, reduced interference, and enhanced component interoperability.
DSC 1.2 adds native 4:2:0 and 4:2:2 coding, support for up to 16 bits per color, and High Dynamic Range (DR) support.
More details on Display Stream Compression 1.2 can be found via the VESA.org press release.
