ITU-T Y.1991

Abstract

This Recommendation contains terms and definitions and a framework relevant to providing a general understanding of IPTV. This Recommendation is not simply a compendium of terms and definitions. The primary purpose of this Recommendation is to provide a context for the use of certain terms and definitions to avoid misunderstandings in IPTV and IPTV related activities. Thus, the definitions are arranged in a specific order and certain necessary relationships are illustrated. This Recommendation uses terms and definitions, which are considered particularly suitable and applicable to IPTV work and that have already been defined in published ITU-T Recommendations.
