摘要: An open digital watermark system and methodology having various features for unifying watermark production and processing among diverse user multimedia terminals (112), such as set top box, that may be OPIMA compliant. In accordance with specific aspects, intentional image warping is employed to combat pirating, the analog video channel used to download programming, packet signature implemented for watermark insertion by pixel replacement and use of the data stream made to reduce local data processing and storage.
