For distributed environments, the component based software framework and object-oriented technology are used in CoMM. Which contributs that it may be configured for various multimedia services with the reusable components conveniently. Also, the active QoS adaption mechanism, which protects the server from overload with the management of the resource vector, is introduced in detail.展开更多

By computing certain fractal parameters, a fingerprints core and delta fields can be roughly detected. Experimental results demonstrate this method to be not only more efficient than the single fractal dimension method, but also more noise resistant than the traditional schemes.展开更多

In this paper a scheduling scheme, called Combined MQL/FCFS (CMF), of short video clips inthe jukebox is proposed. Simulation shows that the proposed scheme balances the efficiency andfairness, and reduces the defection probability and increases the throughput significantly comparedwith MQL and FCFS schemes.展开更多
