摘要： A media player providing real time rewind playback of a played media file having segments of frames. A last segment N of the played media file is cached and rendered on a device, such as a mobile device, then a previous segment N−1 is cached and rendered, and the process continues until there are no more segments of the played media file to cache and render. Only a segment of the played media file is cached at a time, rather than the whole media file, such that the played media file can be replayed on the fly.
