Open the CIPO recordAbstract From the Canadian patent
A video reproducing apparatus that stores video programs on multiple removable media, automatically changes the removable media, and supplies requested video programs to multiple terminal devices has a control unit that stores predicted times at which the programs currently being reproduced will require a change of removable media. When a program request is received, the control unit calculates the media change times of the program, and adjusts these times according to the stored predicted times. The adjustments enable all terminals to receive video programs without noise or interruption when the removable media are changed.

Why it's free to use
- Filed August 6, 1999 and granted December 11, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 6, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 6, 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.
