3 Definition of IPTV IPTV is about sending video streams from a source (a streaming device where the content is distributed from) to a terminal. Video traffic can be divided in two categories: broadcast and video on demand. IPTV services are multimedia services such as television/video/audio/ text/graphics/data delivered over IP-based networks managed to provide the required level of QoS/QoE, security, interactivity and reliability (Definition of ITU-T). 3

4 What is Open IPTV Forum The Open IPTV Forum (OIPF) is a organization that has developed an end-to-end solution to allow any consumer end-device, compliant to the Open IPTV Forum specifications, to access enriched and personalized IPTV services either in a managed or a non-managed network. To that end, the Open IPTV Forum focuses on standardizing the user-to-network interface (UNI) both for a managed and a non-managed network. 4

6 Open IPTV Forum Scope Consumer Domain: the domain where the IPTV services are consumed. A consumer domain can consist of a single terminal or a network of terminals and related devices for service consumption. The device may also be a mobile end device; in this case, the delivery system of a network provider is a wireless network. Network Provider Domain: the domain connecting customers to platform and service providers. The delivery system is typically composed of access networks and core or backbone networks, using a variety of network technologies. Platform Provider Domain: the domain providing common services (e.g., user authentication, charging etc.) to IPTV Service Providers. Different types of service can be provided to a subscriber including IPTV services, personalized communication services, etc. IPTV Service Provider Domain: the domain providing IPTV services to the Consumer Domain. In the context of television services on IP, the IPTV Service Provider acquires/licenses content from Content Providers and packages this into a service. Content Provider Domain: the domain that owns or is licensed to sell content or content assets. 6
