Open the CIPO recordAbstract From the Canadian patent
A digital color video signal is subsampled into a special YUV block format that arranges the data in small groupings of interleaved V U and Y values in , a left-to-right, top-to-bottom sequence across a video frame. This format results in significantly-reduced hardware memory requirements in the video reception system. Interpolation or dithering is also used to reduce unwanted artifacts in the resulting images.

Why it's free to use
- Filed September 8, 1995 and granted June 25, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 8, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 8, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
