Claim Text:
1. A method for switching between two redundant bitstreams comprising the steps of: (A) receiving a first bitstream and a second bitstream, wherein (i) said first bitstream is presented to a first pipeline and said second bitstream is presented to a second pipeline and (ii) said first bitstream and said second bitstream contain redundant information received from independent sources and (iii) an output of said first pipeline is presented to an output pipeline; (B) processing said first bitstream in said first pipeline and said second bitstream in said second pipeline; and (C) if said first bitstream fails, presenting an output of said second pipeline to said output pipeline, wherein (i) data in a buffer in said second pipeline is used to pass a next frame to said output pipeline and (ii) a size of a buffer of said first pipeline and a size of said buffer in said second pipeline are adjusted based on a time of reception of said first and said second bitstream.
