ABSTRACT:
A video port interface that determines the amount and type of incoming data by reading information from certain memories. A first memory indicates a first format of the incoming data. A second memory indicates a second format of the incoming data. Finally, a third memory indicates a number of lines of the first format that will be received. The video port interface reads all three memories at the beginning of each frame, then counts incoming lines until it reaches the line indicated by the third memory. At the end of that line, the video port interface switches from processing the data in the first format to processing data in the second format.
