Abstract: Systems and methods are provided for the fast and effective tuning of a dual tuning audiovisual display system, such as a television. The dual tuners are selectively coupled via a selector to the display. In the preferred embodiment, one tuner is adapted for connection to a cable system with tuning via a cable box, typically controlled by the television via transmission from the television. Ordinarily, the speed of channel changing on the cable box is slower than tuning via the tuner adapted for connection to the bare cable. A control system determines whether a desired channel is available in the channel map for the tuner adapted for connection to the bare cable. If it is available, the tuning is made with that tuner. If the desired channel is not available in that channel map, but is available in the channel map associated with the slower tuner, such as premium channels available through a cable box and the associated channel map, then the cable box containing tuner system is selected.

Abstract: Apparatus is provided for presentation of images from multiple sources on a monitor or television at the same time. In the preferred embodiment, the system comprises a picture-in-picture display, wherein a main picture has overlayed on it a picture-in-picture (PIP) occupying a minor portion of the main picture. In one mode of operation, called a review mode, the PIP displays the channel which had been displayed on the main picture prior to the channel change. In another mode of operation, called the preview mode, the main picture is selected by operation of a channel selection device, such as an up channel selector, and the PIP contains the next sequential channel in the list associated with that channel selection device. Such a list may be predefined, such as in the case of sequential channel selection either in an up or a down direction, or by use of a favorite channel list.
