This Report comprises a report on the current “state of the art” of digital content protection for broadcast television and related services.
This Recommendation describes the service requirements and functional framework architecture for support of IPTV servicesto 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 an IPTV terminal device (IPTV TD) that enables a migration path for the support of basic IPTV services, for current terminal devices usedfor other TV delivery services. This Recommendation identifies architectures and functions needed for the IPTV TD to support basic IPTV services, and is intended to meet immediate demands of current TV delivery services to rapidly deploy basic IPTV services.
