Abstract
A video controller for controlling at least two video displays incorporates a video memory for storing first and second video frames of interleaved pixel data. A video memory controller connected to the video memory sequentially reads data for a first pixel from the first video frame and data for a second pixel from the second video frame. Each pixel data is in turn transferred to a look-up table connected to the video memory controller which converts the first and second pixel data to first and second display data. A selector coupled to the look-up table alternately routes the first display data to one video display and routes the second display data to the other video display.
