Streaming Video Transmission and Controlling Strategy Based on Wavelet EBCOT Coding Over IP Network
Zhang Fang · Chinese Journal of Computers · 2004
In order to meet the requirements of QoS to transmit video streaming over present best effort network, a new streaming video transmission and controlling strategy based on wavelet EBCOT coding over IP network is proposed in this paper. The strategy analyzes the bit streams encoded by EBCOT and them into multiple transmission layers according to different importance, then applies unequal packet loss protection to them according to the network bandwidth estimation and channel state. The experimental results show that the proposed scheme can highly improve the error resilience of the bit stream, as well as efficiently relieve the IP network congestion, and it can obtain up to 1.2dB in PSNR when the transmission is unreliable.
