The Consumer Electronics Association launched new standards activity to support wider, 21:9 aspect ratio TV screens. The CEA is calling for industry participation in a standards update to investigate incorporation of methods for signaling delivery of the presence of 21:9 video into CEA 861, "A DTV Profile for Uncompressed High-Speed Digital Interfaces."

CEA-861 establishes protocols, requirements and recommendations for the utilization of uncompressed digital interfaces by consumer electronics devices such as digital TVs, digital cable, satellite or terrestrial set-top boxes, and related peripheral devices. CEA's Video Systems Committee has begun developing specifications for signaling the presence of 21:9 aspect ratio video. As video displays with 21:9 aspect ratio are now appearing in the marketplace, adding this feature to the standard is expected to more efficiently deliver such video to DTV receivers with native 21:9 displays.
