Seamless video handoff in session mobility over the IMS network
… session mobility over IP Multimedia Subsystem (IMS) networks. Our system is built on top of an IMS network, which we believe to be the best platform for session mobility deployment, as it merges mobility and Internet services. The system combines two techniques to achieve seamless video handoff: …

Delivering personalised advertising in IMS-based IPTV through direct marketing
Multimedia applications and communication services are offered to users free of charge over the open Internet. However, since the Internet is a best effort network, these services are not associated with any Quality of Service (QoS) and Quality of Experience (QoE) guarantees. Furthermore, security …
