Patent

CA 2258823

An audiovisual display system providing a fast tuner system includes a display, a plurality of tuners adapted for connection to a source of information, and a selector coupled to the plurality of tuners to selectively couple one of the plurality of tuners to the display. A control system is coupled to the plurality of tuners and the selector for toggling the selector in response to channel change instructions to cyclically couple one of the plurality of tuners to the display. When a first tuner of the plurality of tuners is coupled to the display in response to a first sequential channel change instruction, the control system preemptively tunes a second tuner of the plurality of tuners to a sequential channel, whereby when a second sequential channel change instruction is received, the control system toggles the selector to couple the second tuner of the plurality of tuners to the display. The system may be a television including one or more internal tuners and/or an external tuner, such as a VCR.
