Quick transfer of media stream in FMC environment

We investigate ways to reduce the delay when transferring media streams among networked media devices based on session initiation protocol (SIP) and its extensions. We assume that cellular phones act as control points (CPs) for media devices connected to home networks and call such networks “mobile personal area networks (mPANs)”. We propose a pre-negotiation scheme for SIP streaming mobility that enables a CP to quickly transfer media stream in an mPAN. Experimental results showed that the proposed scheme can achieve a signaling delay of less than 26 ms, which is 1/10th that of the previous scheme.
