An Internet television program guide system is provided that allows a user at a multimedia system to access information related to television programs over an Internet communications link.

The user can perform database searches on the program guide listings (e.g. to search for a particular type of television program). If desired the user can select an option that directs the multimedia system to tune directly to a television channel for a selected program or to a related television program guide or movie guide service on a television channel. The user can order pay-per-view events using the system.

Why it's free to use
- Filed December 9, 1997 and granted August 4, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 9, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 9, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
