Video watermarking: Requirements, problems and solutions

This chapter will discuss the requirements and the problems of video watermarking in the video broadcasting case by following the European Broadcasting Union (EBU) Technical Requirements. We will review one of the first European Video Watermarking System, TALISMAN (Tracing Authors right by Labeling Image Service and Monitoring Access Network), which was capable of embedding and extracting invisible watermarks in real-time. While on the one hand the TALISMAN system proved to have satisfactory visual quality and robustness regarding compression on the other hand improvements were needed to meet the requirements of the EBU. We show results from our recent research and outline how our extended solution can cope with geometric distortions.
