Digital watermarking

PixelTools' patented MPEGEscort®watermarking software slightly alters a compressed MPEG video to insert a visually indiscernible digital data file - video watermarking. Any copies of that watermarked video also carry the hidden watermark. Knowing the correct key,Escort® can extract the hidden file. For example, the file could have identification data useful later if abuse of copyright fair-use is suspected. Watermarking is much faster than video real-time, and is very compatible with networked or point-of-sale video distribution.
