However, free-riders that down without providing leads to unstable video quality of peers in the system. Current research of incentive methods in P2P media streaming system modifies the original incentive methods in the P2P file sharing systems. Each peer allocates resource according to the amount of receiving data from peers. These methods are successful in some kinds of media streaming systems but not all of these systems. We use the reputation-based method for building an incentive mechanism in the push-pull based media streaming system. Peers rate to others peers and use the overall system contribution of each peer for making transmission decision. In our incentive mechanism, peers receive different level of video quality according to their contribution of the systems. And free-riders can only receive such a lowest level of video quality.
