In this paper, we examine the prefetching strategies in a peerdriven video on-demand system. In our design, each video is encoded into multiple low bit-rate substreams and copies ...

In this paper, we propose a probabilistic model for web image mining, which is based on concept-sensitive salient regions without human intervene. Our goal is to achieve a middle-...
In conventional video coding, the complexity of an encoder is generally much higher than that of a decoder because of operations such as motion estimation consume significant com...
We present the first analytic study of stream tapping protocols, a family of protocols that provide the most efficient way to distribute videos on demand at low to medium request ...
