This document specifies the use of relevant functions for delivery of an IPTV Content on Demand (CoD) Service. An instance of an IPTV CoD Service may be configured to provide a consumer experience similar to that of traditional Video on Demand (VoD) television services. Additionally, the service supports protocols (e.g., HTTP) for direct access to consumer electronic devices. Content may be sourced from within the service provider or across the Internet directly from the content provider. Content can also be delivered to subscriber devices attached to either the service provider?s managed network or a third party unmanaged network (e.g., Content Delivery Network). These CoD service capabilities allow for nomadic service across multiple networks and devices.
