The Digital Broadcaster 32 is a high end card designed for non-linear video editing with framebuffer, capture and video switching facilities. The card requires the supplied "BreakOut Box" which contains all the video connectors for the card. Without the BreakOut Box, the card cannot be used. Various expansions were made for this card including an Image Processor, Hardware Character Henerator, D1 I/O and Sound Stage sound card.
