The invention relates to the synchronization of multi-media events on a computer. A computer of limited core or random access memory makes it difficult to run concurrently various media processes, such as video, music, and titling. The invention provides a way of loading such processes into such memory so as to approximate optimally the desired synchronized production when such processes are played. The invention also provides a way of parameterizing the play of the video process to the play of the music process.

Why it's free to use
- Filed December 3, 1990 and granted October 26, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 3, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 3, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
