Supporting Scalable Multimedia Streaming over Converged DVB-H and DTMB Networks
This paper studies an efficient solution for transporting scalable video over multi-standard integrated multimedia broadcasting networks, namely DVB-H and DTMB. A novel approach, called network-aware stream adaptation (NASA) framework, is developed within this context to deliver the scalable video streams to the end users over the underlying heterogeneous broadcasting standards. Simulation results prove that the proposed scheme significantly improves the channel utilization and achieves better video quality. An efficient dynamic stream adaptation (DSA) mechanism is then foreseen to perform the most appropriate stream adaptation in response to the current reception conditions, network resources, and channel variations, offering progressive perceived visual display quality and fine-granularity QoS performance.
