Systems and methods for generating a master video stream from at least two live video streams are provided in this disclosure. The systems include a combination component that combines the live video streams to generate the master video stream. In one aspect, the live video streams can be copies of the same recording that are multicast from different locations according to User Datagram Protocol. The live video streams suffer different errors, such as stream corruption or stream error, due to the transmission. The combination component eliminates the errors in the live video streams due to transmission and creates a substantially error-free master video stream.
