摘要
Abstract
In recent years, the technology of P2P VOD has got a comprehensive development. It is widely accepted that people use a streaming media player based on P2P to play videos on Internet. But for many reasons, the users have to wait for a long time when they perform fast forward, fast rewind, and jump operations in playing videos, which is quite different from performing those operations on videos in local computers. Consequently, the users are not satisfied with it. In order to solve this problem, researchers propose many VCR solutions, which include the passive technologies and the active technologies. The passive technologies focus on reducing the time of locating the source node and downloading sources from it, at the same time, improve the possibility of saving the information of the source node. Active technologies focus on improving the possibility of the pre-saved content of video and the information of the source node. This paper plays emphasis on introducing the characteristics of these algorithms and comparing their merits and limitations. At the end, a view of the future development of VCR will be given in order to provide a reference to future study.关键词
