ITU-T H.762

Abstract

This Recommendation describes the high-level functionalities of the lightweight interactive multimedia framework (LIME) for IPTV. LIME supports functionalities in IPTV terminal devices to provide interactivity and a variety of content such as audio, video, graphics and text. Expected services include additional data such as text to enrich TV programmes, and two-way portal pages. <br>This Recommendation describes the profile (called "LIME-HTML") of XHTML1.0 [b-W3C XHTML], the profile (called "LIME-CSS") of cascading style sheets 1(CSS1), and a part of CSS2, the profile of document object model (DOM) (called "LIME-DOM"), and a script language (called "LIME-Script") that is a subset of ECMAScript but has functional extensions required for IPTV services. It describes the use of IP-based protocols for transport of LIME and IPTV-related services.
