Open the CIPO recordAbstract From the Canadian patent
An image capture and transmission system includes first and second imaging devices. A timing signal generator produces a timing signal. A common drive circuit operates for driving the first and second imaging devices at equal timings determined by the timing signal. A first signal processor operates for converting an output signal of the first imaging device into first digital video data. A second signal processor operates for converting an output signal of the second imaging device into second digital video data. The first digital video data and the second digital video data are processed into a stream of packets. The packet stream is transmitted to, for example, a network.

Why it's free to use
- Filed July 7, 1999 and granted April 23, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 7, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 7, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
