Abstract
A multiple information decoding system and method are provided in which multiple information content is decoded sequentially and provided to a viewer such that the viewer perceives the information content as being simultaneously decoded. One embodiment of the system and method is in a video display system where RF channels are decoded by a single tuner for concurrent presentation to a display.

28. A system for sequentially presenting data, said system comprising:
-
means for presenting multiplexed signals to a tuner so as to obtain data from selected channels of said multiplexed data;
means for selecting which of said channels is desired at any point in time; and
means for controlling said selecting means so as to alternate within 100 milliseconds between a plurality of said channels.

29. A video system having a plurality of presented informational displays, each such display relating to a specific available one of a like plurality of RF signals, each such signal being decodable to form a video image, and all of said informational displays presented concurrently on a single display such that a viewer perceives that all of the presented images are presented concurrently, said system including:
-
means for decoding the RF signals related to said presented informational displays; and
means for associating with each such informational display said decoded RF image.
