A system and method for recovering from data loss are described including monitoring a first bit rate video data bit stream to determine if there is frame loss or damage, multiplexing decoding parameters of a second bit rate video data bit stream, the second bit rate video data bit stream and the first bit rate video data bit stream, if there is frame loss or damage, demultiplexing the first bit rate video data bit stream and the second bit rate video data bit stream, decoding the first bit rate video data bit stream, removing damaged frames from the first bit rate video data bit stream, decoding the second bit rate video data bit stream, up-sampling frames from said processed second bit rate video data bit stream if said processed second bit rate video data bit stream has a lower resolution than said processed first bit rate video data bit stream and merging frames from the second bit rate video data bit stream and the first bit rate video data bit stream. |
