Advanced Television Enhancement Forum (ATVEF)

"The Advanced Television Enhancement Forum (ATVEF) is 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 television. ATVEF closed at the end of 1999 and turned over the specification to the ATV Forum and Society for Motion Picture and TV Engineers (SMPTE). ATVEF?s primary area of interest was interactive television. One aim was to aid in extending the Internet to broadcast media. ATVEF-compliant systems do not need to be fully digital and thus can include the use of the Vertical Blanking Interval (VBI). See also vertical blanking interval (VBI), Society for Motion Picture and TV Engineers (SMPTE), and Hypertext Markup Language (HTML)."
