In one embodiment, a method comprises identifying a plurality of frames of interest from a primary stream of encoded frames. The method further comprises selecting at least one of the frames of interest for inclusion in a separate redundant stream. The method further comprises producing another encoded instance of the at least one selected encoded frame. The method further comprises associating the another encoded instance of the at least one selected frame in the separate redundant stream with the corresponding selected encoded frame in the primary stream. The method further comprises providing the primary stream, the separate redundant stream, and a common clock reference to a decoder.
