Abstract
Method and modular system for generating, capturing and re-displaying SDI 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 before being serialized into a output data stream. On the capture side, a de-serializer/equalizer accepts an input data stream extracts Y (luminance), CB (blue-difference chroma) and CR (red-difference chroma) data along with clock/sync information which can be used for re-display. Optional support of HDMI, DVI and analog formats, such as composite video, raster video and stroke video, allows a single instrument to generate, acquire and process virtually all known video interfaces, using standard or custom image/formats.
