VESA seeks industry input for new AR/VR coding system

The Video Electronics Standards Association (VESA) has put out a call to display industry experts in drafting a new compression coding system for AR/VR displays.

VESA said the “call for requirements” is seeking help in the development of a new compression coding system (known as VDC-X), to address new AR/VR display systems and their unique requirements.

“The next generation of AR/VR systems promises to revolutionize the way we interact, communicate, work, and live,” VESA said in a statement. “However, there are specific AR/VR display technical challenges that need to be addressed to realize this potential.”

The development of the new VDC-X coding system is being overseen by VESA’s Display Stream Compression Task Group.

While VESA DSC and VDC-M have been deployed within VR products either in a wired set interface from a host processor or embedded within a headset, some recent implementations do not conform well to several assumptions upon which these previous codecs are based, VESA said.

“VDC-X is intended to provide bounded variable rate encoding of sparse color component planes, and it is not intended to address all the use cases of DSC and VDC-M where color components for a pixel are transmitted together,” VESA said.

It went on: “Therefore, the compressed bit rate for visually lossless coding of non-sparse content is not anticipated to be as low as that which can be achieved for DSC. VESA will benchmark any new designs to the same visually lossless standard upheld by DSC and VDC-M.”

The task group is seeking input from VESA members, other standardization bodies, and potential OEMs who may deploy VDC-X in products to understand their specific applications and added requirements for a new intraframe coding standard.

Responses are required to be sent to VESA by Monday December 11. For the full details of how to respond to VESA’s request visit here.
