Abstract

An improved video streaming method and system that reduces video stream playback dropouts when video data flow from a server is degraded or interrupted. Two adaptive bitrate video streams of the content are operated in parallel with video quality that can be adjusted independently. The first stream receives data blocks at a rate generally concurrent with the video playback. The second stream receives data blocks in advance of the playback point and these blocks are buffered. The best available block is used during playback. Buffered second stream blocks can be used to continue playback when the network connection is compromised or interrupted.
