CEA publishes 3D video specs
Included in a batch of five new standards, the US’s Consumer Electronics Association (CEA) has published standards on 3D video, which are now available to guide designers as they develop innovative products for consumers.
“The release of these standards follows the very successful CEA Technology and Standards Forum in Dallas,” said Brian Markwalter, senior vice president, research and standards, CEA. “CEA’s standards committees are always looking for new ways to help grow the consumer electronics industry through technological cooperation. The breadth of topics covered by these new standards reflects the innovation in the CE industry.”
One of the five standards – CEA-708.1, Digital Television (DTV) Closed Captioning: 3D Extensions – describes how to send closed captioning information for 3D video, while CEA-2038, Command–Driven Analog IR-Synchronized Active Eyewear, describes how to control ‘active’ 3D glasses worn by viewers using an infra-red signal sent by a TV set. This enables viewers to continue wearing glasses as content switches from 2D to 3D mode, and also enables two viewers to see two different images, which might be desirable in video gaming.
