碩士 === 國立中央大學 === 電機工程研究所 === 91 === Due to the rapid development of the networking and communication, the distribution of digital data is faster and arbitrary. In addition, the semiconductor technology is rapidly developed, the process techniques is better than better. The System-On-a-Chip (SOC) is a trend in those years. There are more consumer product is produced and popular, such as DSC, digital video ...etc. In order to protect copyright of the multimedia data, a data capturing, compressing and ownership declaring is done at the same time. In this paper, a watermarking system for embedding spatial and transform domain by configuring and its Very Large Silicon Integration (VLSI) implementation is presented. The watermarking system applied spread spectrum techniques and Toral automorphism to build a watermarking system 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. We also implement the whole design by synthesizing with TSMC 1P4M 0.35μm standard cell. The simulation speed can reach 50 MHz, and the chip size is for 29128.742 gate counts.
