Open the CIPO recordAbstract From the Canadian patent
A system capable of synchronizing and automatically resynchronizing multiple DCRSi units includes a monitor (3) for monitoring respective channels output by each unit (X Y, Z) for frame sync, words which have been simultaneously inserted (8) into each unit (X Y, Z) during recording. If the frame sync words are not present simultaneously, the sequence and magnitude of the offset is determined (3) and synchronization of the data output is adjusted by adding additional reads to the channels that slip behind.

Why it's free to use
- Filed March 4, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 4, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 4, 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.
