Recommendation ITU-T Y.1910 describes the IPTV functional architecture intended to support IPTV services based on the IPTV service requirements and definitions. Starting from a basic description of IPTV roles and services, a high level IPTV functional model is outlined. This model is then developed into a set of functional architectures which support NGN and non-NGN transport networks, as well as operation modes with or without IMS. |
