Abstract
A method for switching between two redundant bitstreams. The first bitstream may be presented to a first pipeline. The second bitstream may be presented to a second pipeline. The first bitstream and the second bitstream may contain redundant information received from independent sources. If the first bitstream fails, the method may present an output of the second pipeline to the output pipeline. Data in a buffer in the second pipeline may be used to pass a next frame to the output pipeline. A size of a buffer of the first pipeline and a size of the buffer in the second pipeline may be adjusted based on a time of reception of the first and the second bitstream.
