4.2.8 ATVEF and OCAP<br />
The two primary organizations shaping iTV technological standards in the U.S.<br />
are the Advanced Television Enhancement Forum (ATVEF) and CableLabs’ OpenCable<br />
project. ATVEF is a non-profit coalition of broadcast, cable, PC, and consumer<br />
electronics companies formed to promote interactive television standards and<br />
deployment. ATVEF defines the standards used to create content that can be delivered<br />
over analog and digital television broadcasts, and a variety of networks, including<br />
terrestrial broadcast, cable, and satellite. The ATVEF 1.0 Content Specification requires<br />
support for HTML 4.0, JavaScript 1.1, Cascading Style Sheets (CSS 1), and MIME<br />
extensions. Possible directions for future content levels include Dynamic HTML,<br />
synchronized multimedia, 3-D rendering, tuning, XML, Java, and higher-quality audio<br />
(Pignetti & Capria, 2001; ETV Cookbook, 2003a).<br />
CableLabs’ OpenCable project is an interoperability initiative supported by more<br />
than 400 cable television companies, software technology companies, and hardware<br />
manufacturers. The OpenCable Applications Platform (OCAP) is CableLabs’ middleware<br />
