VESA and MIPI Alliance Announce New Display Stream Compression Standard

VESA and MIPI Alliance Announce New Display Stream Compression Standard

Enterprise & IT Apr 23,2014 0

The Video Electronics Standards Association (VESA), working in liaison with the MIPI Alliance, have finalized the Display Stream Compression (DSC) Standard, version 1.0, designed reduce the bandwidth requirements of 4K and higher-resolution video by more than 60 percent. VESA developed the DSC standard as an industry-wide compression standard for video interfaces, offering visually lossless performance and low latency. DSC has been adopted into VESA's embedded DisplayPort (eDP) v1.4 and into MIPI Display Serial Interface (DSI) Specification v1.2, which are used for embedded display interfaces within mobile systems, including smartphones, tablets and laptops. It is anticipated that the DSC standard will also be used for external display interfaces to computer monitors and televisions.

As display resolutions increase, the interface payload capacity must increase either with more power-consuming bandwidth, video data compression, or both. Displays going beyond 4K resolutions will push the video data rate beyond the current limits of the interface standards. For example, standard 1080p displays require a video data rate of 3.5 gigabits/sec; 4K displays at 60Hz require 14 gigabits/sec; and future 8K displays will require over 50 gigabits/sec. VESA?s DSC standard version 1.0 enables up to 66 percent data rate reduction, extending battery life in mobile systems and laptops, while simplifying the electrical interface requirements for future 4K and 8K displays.

"VESA recognized the need for display interface compression in mobile devices to extend battery life without compromising visual quality," said Dale Stolitzka, VESA Display Stream Compression Task Group Chairman and member of Samsung Display America Laboratory. "In addition, on-going development of DisplayPort standards, which includes 8K resolution support, foresaw the need for compression because of inherent limits in the existing display interface cables. VESA realized that compression was becoming a common need in the industry, and that a standard compression coding system could meet these common display interface needs."

VESA claims the new encoding scheme provides "visibly lossless performance for graphics, text, images, and video," using a combination of technologies that includes delta pulse code modulation (DPCM) encoding, an Indexed Color History (ICH), an entropy encoder, and a rate buffer. It is a less complex compression algorithm than MPEG, it provides a provides a lower compression rate and consumes fewer system resources including power.
