(Advanced Television Enhancement Forum) A consortium of broadcast, cable and computer companies founded in 1998 that developed the ATVEF Enhanced Content Specification, an HTML and JavaScript-based format for adding content to interactive TV. ATVEF closed at the end of 1999 and turned over the specification to the ATV Forum and SMPTE.
In its short year and a half history, ATVEF compiled a collection of intellectual property from its members about interactive TV that provides a wealth of information about content creation and distribution. After ATVEF's closing, this technology continued to be made available from ATVEF Licensing LLC in Boulder, CO. See
