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.

Abstract: A system and method for a single conversion tuner which generally uses phase shifted in-phase and quadrature-phase signal paths as an image rejection circuit. Through the use of broadband input LNA and mixer circuits, substantially the entire input signal bandwidth may be processed in the tuner. The broadband input LNA may pass the signal through to the mixers, which may split the signal into in-phase and quadrature terms. Then the in-phase term may be shifted by plus 45 degrees and the quadrature may be shifted by minus 45 degrees. When the terms are subsequently summed together, the desired signal components add together, while the undesired image components subtract from each other. In this way the image signal is suppressed, thus generally eliminating the need for a notch filter. A phase error correction feedback loop may be implemented to compensate for errors between the separate circuit paths.
