Abstract
Abstract An interactive high definition display system generates (48) its own graphics display data, accepts multiple video signals (12) and graphics display signals (16, 20) based upon multiple standards, and selectively produces therefrom an integrated video and graphics display featuring multiple images or compositing. The incoming video signals (12) are decoded (30) into corresponding RGB signals, digitised (30) and written into memory (30). The incoming and internally generated graphics display data signals are also written into memory (42). According to preprogrammed instructions, or interactively according to instructions received via a computer interface (46), an integrated, multiple image or composite display pattern with both active video and graphics display images can be generated by selecting from and arranging for display the stored video and graphics display data, and viewed on a high definition display or stored on a high definition video tape recorder.
