How to achieve robustness against scaling in a real-time digital watermarking system for broadcast monitoring
In the European Esprit project VIVA (Visual Identity Verification Auditor) a real-time digital watermarking system for broadcast monitoring has been investigated and implemented. On top of the usual requirements for watermarks, the VIVA watermarking system has to satisfy an additional number of constraints. One of the most important constraints in a broadcast environment is the robustness of the watermark against scaling. This paper describes how robustness against scaling is achieved in the VIVA project. Furthermore, a real-time implementation of the algorithms is discussed. Experimental results prove the effectiveness of the algorithms

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

Implementation of a real-time digital watermarking process for broadcast monitoring on a TriMedia VLIW processor
The implementation of a real-time digital watermark embedder and detector for television broadcast monitoring is addressed. A TriMedia processor with 4 BOPS (billion operations per second) is used for a software implementation. The performance of the system is tested in a laboratory environment under real-time conditions. The results prove the feasibility of a professional broadcast surveillance system, which is the aim of a European Esprit project named VIVA (visual identity verification auditor)
