Open the CIPO recordAbstract From the Canadian patent
Image data are defined by color vectors each composed of vector factors. Each vector factor specifies the brightness and color difference of a dot. The image data are transmitted with a normal timing when the vector factors correspond to dots of the image one for one, and are transmitted with another timing in another case to scroll the image horizontally.

Why it's free to use
- Filed September 17, 1993 and granted July 15, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 17, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 17, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
