<p>In a method and apparatus for processing color video signals, a switching network controlled by a control computer initially applies a composite video signal to a single analog to digital converter for storage in memory. The composite signal is then repeatedly retrieved from memory in order to be sequentially decomposed into each required color characteristics such as red, blue and green. The decomposed signal is also applied to the input of the switching network so that the control computer can alternately multiplex each of the three decomposed signals into the memory. In this manner, the composite red, blue and green information is sequentially stored in memory for manipulation by a signal processing computer. This eliminates the need for multiple analog to digital converters operating in parallel.</p> |
