Implementation of a real-time digital watermarking process forbroadcast monitoring on a TriMedia VLIW processor

摘要

The implementation of a real-time digital watermark embedder anddetector for television broadcast monitoring is addressed. A TriMediaprocessor with 4 BOPS (billion operations per second) is used for asoftware implementation. The performance of the system is tested in alaboratory environment under real-time conditions. The results prove thefeasibility of a professional broadcast surveillance system, which isthe aim of a European Esprit project named VIVA (visual identityverification auditor)
