Rate Adaptation and Admission Control for Video Transmission with Subjective Quality Constraints
Chao Chen, Xiaoqing Zhu, Gustavo de Veciana +2
Adapting video data rate during streaming can effectively reduce the risk of playback interruptions caused by channel throughput fluctuations. The variations in rate, however, also…
Modeling the Time-varying Subjective Quality of HTTP Video Streams with Rate Adaptations
Chao Chen, Lark Kwon Choi, Gustavo de Veciana +3
Newly developed HTTP-based video streaming technologies enable flexible rate-adaptation under varying channel conditions. Accurately predicting the users' Quality of Experience (Qo…
A Markov Decision Model for Adaptive Scheduling of Stored Scalable Videos
Chao Chen, Robert W. Heath, Alan C. Bovik +1
We propose two scheduling algorithms that seek to optimize the quality of scalably coded videos that have been stored at a video server before transmission.} The first scheduling a…
