Abstract: An audio/video processing device includes a first pipeline and a second pipeline. The first pipeline is configured to receive a first program stream and decode the first program stream. The second pipeline is configured to receive a second program stream and at least partially decode the second program stream. In response to selection of the first program stream, the first pipeline is further configured to output the decoded first program stream and the second pipeline is further configured to discard the partially decoded second program stream. In response to selection of the second program stream, the second pipeline is configured to fully decode the second program stream and output the decoded second program stream.
