A Practical Coder of Fully Scalable Video over Error-Prone Network

Abstract

The paper is mainly devoted to explore practical scalable video coding technologies over error-prone wireless and mobile network with fluctuant bandwidth and various terminals. The new coder supports full scalability of spatial resolution, SNR quality and temporal in a flexible and simple method. Instead of common-used but complex MCTF-based scheme the new coder integrates smartly several optimized and improved technologies, i.e. so-called Hierarchical-B-Picture-Like, DWT, successive multi-level quantization, and SPIHT. The proposed coder can produce embedded bitstream satisfying various requirements of bandwidth, resolution and SNR of terminals over error-prone network. The experiments show that the proposed coder is practical and flexible and works well over error-prone network.
