Open the CIPO recordAbstract From the Canadian patent
The invention consists of a system and method for transferring video images from video sources to video receivers using a video server as an intermediary. The video server creates a list of all the requests from the video receivers for a video image from a video source. The video server requests the video image from the video source and then sends the video image to each video receiver on the list. The video source is only required to send one image for any number of requests from video receivers and the video sources and video receivers have no direct connection to each other. The load of handling many video sources and many video receivers can be distributed amongst multiple video servers.

Why it's free to use
- Filed June 13, 2002 and granted December 11, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 13, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 13, 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.
