A Broadcast Monitoring System based on the compound watermarking technology for Digital TVs

摘要

As the rapid development of the digital television broadcasting,the security of data transmission of digital TVs become more and more important.A broadcast monitoring system based on compound watermarking is proposed in this paper.After discussing the application scenarios,we first introduce the broadcast monitoring system in ? high level.Then more details is given about the compound watermarking which utilizes both OCT based robust watermarking and LSB based fragile watermarking.By utilizing the compound digital watermarks,the proposed monitoring system offers a method for protection and detection in the system-wide.
