Distributed Prefetching Scheme for Random Seek Support in Peer-to-Peer Streaming Applications
Overview Through analysis of large volume of user behavior logs during playing multimedia streaming, it extracts a user viewing pattern. The pattern indicates that random seek is a pervasive phenomenon, contrary to the common assumptions that users would watch a video session sequentially and passively in most works on peer-to-peer streaming. This paper proposes to use efficient prefetching to facilitate the random seek functionality. Because of the statistical nature of the user viewing pattern and the ignorance of the users to the content, it argues that the pattern should be used as guidance to the random seeks. Based on the pattern, it set up an analogy between the optimization problem of minimizing the seeking distance and the optimal scalar quantization problem.
