Digital content is extracted from single and multiple-program transport streams for subsequent non-real-time (background) transmission in a bandwidthefficient manner.

Why it's free to use
- Filed December 6, 2000 and granted April 17, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 6, 2020.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
