Abstract: To obtain a credible and reliable streaming media system,this paper firstly analyses various possible network topologies,as well as different size data scheduling methods and their impacts,and presents an adaptive scheduling algorithm for different heterogeneous networks.Next,this paper studies real-time streaming quality assessment methods,and designs adaptive streaming adjustment method based on its results.In addition to this,according to the system state information and key data obtained,this paper analyses the system availability under various faults or attack conditions,then designs appropriate fault detection and system recovery method.Finally,the system implementation method to construct a large scale real-time reliable streaming media system is presented in this paper.

Key words: credible and reliable streaming media system, adaptive scheduling algorithm, adaptive streaming adjustment method, fault detection and system recovery method
