IPTV session mobility

This article describes a novel architecture for delivering personalized IPTV experiences to the end users. The framework leverages the IP Multimedia Subsystem (IMS) to quickly enable new innovative, multi-media services. We describe the session flows for a single IPTV session switch between multiple set top boxes (STBs) and between a STB and a PC/mobile device SIP user agent. We also demonstrate how supplementary services like caller ID and advanced telephony features can also be migrated across multiple devices.
