Abstract

A new VLSI architecture of a real-time communication-based watermarking system for the spatial and transform domain is presented. The communication-based watermarking technique applied spread spectrum techniques and a perceptual visual model to build a watermarking system in which it is suitable for raw video sequence watermarking. The proposed architecture is adequate for specific function IP combining with a real-time video encoder.
