Abstract
Abstract An enhanced video special effects system architecture is based on deinterlacing (16) incoming fields of interlaced video and processing the deinterlaced video through video special effects operations (18, 30), each of which benefits from operating on a progressive scan video signal rather than an interlaced video signal.
