IPTV service requirements and framework for secondary distribution
|Publication Date:||1 December 2009|
This Recommendation describes the service requirements and functional framework architecture for support of IPTV services to provide enhanced broadcasting, where broadcast programmes are delivered over existing cable-based secondary distribution networks composed of HFC or FTTx with some enhancements by applications and/or services provided over IP-enabled networks. It addresses the service requirements, use cases and functional components required to support these requirements. Where possible, this Recommendation utilizes the material already developed, or under development, in ITU-T Recommendations related to video service delivery over secondary networks.
This Recommendation describes the use of an IPTV mechanism based on the general ITU-T IPTV functional architecture [ITU-T Y.1910]. The IPTV applications and services addressed in this Recommendation are intended to be transferred over existing cable-based secondary distribution networks and/or other networks to enhance the existing television distribution services.
