Versatile watermark transport system

A watermark transport system comprising:

• a. an elementary data stream preprocessor configured for preprocessing at least one elementary data stream, said preprocessing consisting of either demultiplexing said elementary data stream or including at least one extra elementary data stream among at least one elementary data stream;
• and
• b. a watermark inserter comprising:
• i. a watermark object creator, said watermark object creator configured for creating at least one watermark object, said creating including precomputing at least one watermark change data using watermark metadata, said at least one watermark object comprising:
• 1. said watermark metadata;
• and
• 2. said watermark change data;
• ii. a watermark transporter, said watermark transporter configured for transporting said at least one watermark object, said watermark transporter comprising at least one of the following:
• 1. a packetizer and a multiplexer configured for packetizing and multiplexing said at least one watermark object into said at least one elementary data stream where said demultiplexing occurs;
• and
• 2. an overwriter configured for overwriting said extra elementary data stream with said at least one watermark object where said extra elementary data stream is inserted;
• and
• iii. a watermark object processor, said watermark object processor configured for processing said at least one watermark object,
• wherein said packetizing and multiplexing occurs, said watermark object processor including at least one of the following:
• 1. a demultiplexer configured for demultiplexing at least one packet from said at least one elementary data stream having said at least one watermark object that is packetized and multiplexed;
• 2. a watermarked elementary data stream creator configured for creating a watermarked elementary data stream by using said at least one watermark object to watermark said at least one elementary data stream having said at least one watermark object that is packetized and multiplexed;
• and
• 3. a reinserter configured for reinserting said watermarked elementary data stream into said at least one elementary data stream having said at least one watermark object that is packetized and multiplexed;
• and
• wherein said overwriting occurs, said watermark object processor including at least one of the following:
• 1. a discarder configured for discarding said at least one watermark object after said creating a watermarked elementary data stream;
• and
• 2. a decoder configured for decoding said watermarked elementary data stream.
