Abstract
Method and modular system for generating and capturing DVI video signals. When generating a video signal, data blocks are arranged in a line parameter memory, each corresponding to a complete video line and containing pointers to specific entries for lines of the video signal in a primary image memory holding a main bit-mapped image, and a video line construct memory holding data enable and blanking patterns. Generation of the video signal is initiated by reading the line parameter memory and extracting pointers from the data blocks for a first line of the video signal being generated. Bits from the primary image and video line construct memories are obtained and combined based on extracted pointers to generate the first line of the video signal. A length of the first line of video signal is monitored to determine when it is complete, and then the process continues for each additional line.
