摘要：We have developed two types of real-time video watermarking systems using a VLIW-based media processor. One is an embedding system for HDTV (High-Definition TV), and the other is an embedding system for standard TV. These systems preserve the picture quality of each video frame by using motion estimation and contour detection that optimizes the strength of the watermark. We have developed a watermarking module that incorporates three MAPCAs (media accelerated processors for comsumer appliances) as art of a real-time embedding system for standard TV. For HDTV, we have developed a watermarking system with seven watermarking modules. The system divides an HDTV video into seven segments so that the seven independent modules work in parallel.
