Abstract
A fault-tolerant, cloud-based system can comprise a redundancy control unit capable of switching between transcoded video streams output by two or more transcoders. The redundancy control unit outputs a manifest from one of the transcoded streams and, upon detecting a fault in the stream, can modify the manifest to switch to another of the transcoded video streams. The redundancy control unit can further modify the manifest to flag the discontinuity in the video stream, which allows the player to switch to the new transcoding video stream without error. Other embodiments can include additional redundancies to help provide additional fault tolerance.
