ABSTRACT:
Method and apparatus process a composite video signal, converted it to component video signals which are processed digitally to produce reprogrammable digital RGB graphics signals. Specifically, a composite video signal is first digitized and then processed to convert digitized YUV component video signals into digitized RGB signals by means of a RAM-based table lookup technique optimized to the resolution of each of the component signals so as to minimize memory requirements and computation overhead. In a specific embodiment, a Y or luminance signal having a resolution of 6 bits is employed in connection with a V component signal having a resolution of 5 bits and a U component signal having a resolution of 3 bits without noticeable degradation of RGB color quality.
