A redundant remultiplexer (500) is described which is capable of remultiplexing fixed length transport stream packets. Illustratively at least some of the packets contain program data i.e. data with a sensitive delivery schedule such as variably compressed audio-video data. An example of such variably compressed data is MPEG-2 encoded video. The redundant remultiplexer has a chassis architecture with input modules (521) that receive externally originating transport packets output modules (521) that output externally selected transport stream packets and switch modules (531 532).

Why it's free to use
- Filed May 29, 2003 and granted July 12, 2016. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 29, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 29, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
