Abstract

On a single plug-in card of standard dimensions for insertion in a desk model computer are mounted all the necessary components to provide display on a portion of the computer screen as selected and controlled by the computer, a television picture or similar compatible display, and reproduce an associated audio signal. The miniature television adapter functions within the operating cycle of a host computer capable of operating in a multi-program with split or overlay display screen capability. It does not preempt or override any normal computer functions. Its specially designed signal processing and data word assembly and delivery circuitry make possible delivery of a digitally formatted television data stream at a sufficient speed to enable display according to the model of the device of either black and white or color television images at a rate of thirty frames per second when used with a computer of sufficient operating speed. In its color version, the invention processes the color signal to produce many more colors than the standard palette and also may provide a higher resolution color image at a slower rate.
