6 DSC is now the industry standard data compression across the display interface. DSC was purposely designed to offer low latency, low complexity codec for visually lossless image compression to increase the amount of data carried by a display interface data rate, saving power. Key features include Native 4:2:0 and 4:2:2 coding, Up to 16 bits per color, High Dynamic Range (HDR) DSC is mandated in DP specification and is a powerful feature to allow designers to optimize BW, performance and power for Native DP, DP Alt Mode products and tunneled DP over USB4.
