In this paper, we propose a new video deliverymethod called MTcast (Multiple Transcode based video multicast) which achieves efficient simultaneous video delivery to multiple users with different quality requirements by relying on user nodes to transcode and forward video to other user nodes in P2P networks. In MTcast, each user specifies a quality requirement for a video consisting of bitrate, picture size and frame rate based on the user’s environmental resource limitation. All users can receive video with the specified quality (or near this quality) along a single delivery tree. The main characteristics of MTcast are in its scalability, high user satisfaction degree in received video quality, short startup latency and high robustness against node failure. Through simulations and experiments with our prototype implementation on PlanetLab, we have confirmed that MTcast achieves practical performance in a real environment.
