Open the CIPO recordAbstract From the Canadian patent
An asset provider (10) can identify a segment of a broadcast stream to be extracted at a distribution endpoint and formatted for on demand viewing by cable subscribers (20). An asset provider (10) can use a start time code and a stop time code to identify the start and end of the segment in the broadcast stream. The asset provider (10) can also insert tags into the broadcast stream identifying a segment to be extracted at the distribution endpoint. Upon receiving the broadcast stream, the distribution endpoint can then extract the segment identified by either the start and stop time codes or the tags.

Why it's free to use
- Filed November 12, 2002 and granted January 10, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 12, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 12, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
