Development of Network-attached Real-time Watermarking System Using Media Processor

Abstract

We have developed a network-attached real-time watermarking system for Standard TV using VLIW-based media processor. The transmitter part of the system embeds watermarks to a picture, encodes it with MPEG, then transfers it to the receiver part via network. The receiver part decodes MPEG stream, and detects watermarks from the decoded picture. This watermarking system can be built into an on-line video delivery system with the broadband network.
