This paper presents a video watermarking technology for broadcast monitoring. The technology has been developed at the Philips Research Laboratories in Eindhoven in the context of the European ESPRIT project VIVA Visual Identity V eri cation Auditor. The aim of the VIVA project is to investigate and demonstrate a professional broadcast surveillance system. The key technology in the VIVA project is a new video watermarking technique by the name of JAWS Just Another Watermarking System. The JAWS system has been developed such that the embedded watermarks i are invisible, ii are robust with respect to all common processing steps in the broadcast transmission chain, iii have a v ery low probability of false alarms, iv have a large payload at high rate, and v allow for a low complexity and a real-time detection. In this paper we present the basic ingredients of the JAWS technology. We also brie y discuss the performance of JAWS with respect to the requirements of broadcast monitoring.
