Abstract
A multimedia system has multiple media sources switchable under user control to a common set of output presentation devices. A table stores parameter values for each media source separately, so that selection of a source changes the parameters of the displayed media to values appropriate for that source. A user input device has selection keys, and also has keys for modifying the values of the parameters. The modified parameter values are stored in the table, so that they persist when the same media device is selected at a later time.
