Abstract: A switched input video device has a switched input, video improvement circuitry and/or transcoder circuitry, and a switch for communicating a switched input to at least one of the video improvement circuitry and the transcoder circuitry.

Abstract: A video device includes a video processor operable to upgrade a video image. The video device is capable of displaying video images. The video device includes a video input configured to receive a composite video signal. The composite video signal includes synchronization information, both vertical and horizontal, a luminance and a chrominance. The video device includes a video processor configured to separate the composite signal into separate paths. The video processor is configured to perform video functions on the separate paths individually and combine the separate paths to produce an upgraded video image. The video device also includes a video output configured to receive the upgraded video imaged from the video processor and output the upgraded video image to a display.

Abstract: A high efficiency cathode-ray tube magnetic deflection circuit, providing a sawtooth current waveform at a frequency of 100 kilohertz that includes a FET transistor (11) connected to an anti-phased step-down transformer (15,16,17) for driving an output transistor (18). A co-phased step-up transformer (33,34,35) connected to the deflection yoke (19) provides deflection "S" correction, and also a dynamic focus waveform. The transformers have litz wire windings.
