| Abstract(in English) | We have developed a real-time watermarking system for High-Definition TV (HDTV) using a VLIW-based media processor. The system preserves picture quality of each video frame by using motion estimation and contour detection that optimize the watermark strength. For real-time embedding operation, the system divides an HDTV video frame into seven segments so that the independent seven watermarking modules, each of those comprises three "MAPCA" media processors, works in parallel. |
