Transmission on Scalable Multimedia Stream
Keyword video processing streaming video streaming media real-time scheduling real-time scheduling streaming media streaming video video processing Abstract Recently, with the development in computer, compression and network technology, stream media of network is developing rapidly and has been applied to a great range of different sectors. Stream media has adopted in Internet and Intranet. Along with the development of network, application of stream media technology will play a key role in future development of fast network. Original video/audio data will be stored in the
storage devices after having been pre-compressed by video/audio compression algorithm. When clients have requirements, Stream server retrieves the video/audio data from the storage devices. In this thesis, we proposed a simple and effective real-time scheduling algorithm, adaptive Layer-Based Least-Laxity-First (LB-LLF) scheduling algorithm, to improve the output quality of video/audio on network and to achieve synchronized playback effect. The proposed algorithm considered real-time constraint, unequal
priorities of scalable media stream in different layers, and a good trade-off between coding efficiency and drifting error. This guarantees the effective usage of available channel bandwidth and the better quality of playback in client.
