The Consumer Electronics Association (CEA) today announced five new standards, ranging in topic from accessibility to 3D video to wireless charging, which are now available to guide designers as they develop products.
CEA also released a technical report that addresses television picture brightness.
The new standards are as follows:
ANSI/CEA-2041, Standard for a Round Tactile Indicator, defines a round, raised nib that visually impaired people can use to identify the buttons on a remote control. It was recently approved as an American National Standard;
CEA-708.1, Digital Television (DTV) Closed Captioning: 3D Extensions, describes how to send closed captioning information for 3D video;
CEA-2038, Command-Driven Analog IR-Synchronized Active Eyewear, describes how to control "active" 3D glasses worn by viewers using an infrared 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;
CEA-2042.1-A, Wireless Power Glossary of Terms, defines terminology used to describe wireless charging systems. These systems enable charging of devices by simply setting them on a flat charging surface;
CEA-805-D-1, Data Services on the Component Video Interfaces, provides important clarifications about how digital bits need to be transmitted in a CEA-805-D component video signal; and
The technical report, CEA-TR-1, Home Illumination Study, details results of a comprehensive study of ambient light levels in typical television viewing locations. This information is useful for determining how bright a television picture needs to be to provide a satisfactory viewing experience. Brightness has a direct impact on the energy consumption of the television. This study was conducted in cooperation with the Custom Electronic Design and Installation Association (CEDIA).
