P2P BASED METHOD, DEVICE AND SYSTEM FOR PLAYING MEDIA

摘要

A P2P based method for playing media is provided. The method includes logging in a network; selecting a live broadcasting service or a video-on-demand service, and receiving a judgment result on whether to buffer a data flow corresponding to the live broadcasting service or the video-on-demand service; obtaining the corresponding data flow according to a selection result, and buffering the data flow when the judgment result is yes; and providing the buffered corresponding data flow for a video-on-demand node or a live broadcasting node as a data source of the live broadcasting service or the video-on-demand service. By applying the invention, the live broadcasting and video-on-demand video service can be interfused to realize a free switch from the live broadcasting to the video-on-demand. The data buffered in node disks is applied to the video-on-demand, and according to a source distribution condition, it is judged whether to buffer the currently viewed program, such that sufficient contents are ensured to be used for network applications, thus avoiding waste caused by the over much content stored repeatedly, increasing the utilization ratio of network resources, and improving the use experience of users.
