Televés Clear QAM encoders offer this invisible watermark as an option for video forensics, in an effort to prevent piracy.
All versions of Televés Clear QAM Encoders provide Dolby Digital from analog or digital inputs, closed captioning, and EAS support. They also include ASI input and output for easy EAS signal management, thanks to Televés' innovative integrated RF mixer. They encode both MPEG-2 and H.264 and offer the same comprehensive remote control functionality found in all T.0X headend modules. This makes them ideal for integrating video distribution.
What is 'watermarking'?
Digital watermarking is a mark embedded in image data. It is typically used to identify ownership and copyright of the image. It is a process that hides digital information to verify the authenticity and integrity of the image or to indicate the identity of its owners. It is a widely used technique for identifying copyright infringements and for authenticating banknotes. Like traditional watermarks, digital watermarks are imperceptible to the naked eye, and detection relies on techniques such as the use of an algorithm. It is a passive protection tool that provides data but in no way degrades or restricts access to the image.
In the case of Televés set-top boxes, the watermarking technique is used to embed the Dish Network receiver's serial number in the image. This number is invisible to the human eye but is recorded as a digital watermark if the image is recorded or retransmitted. Thus, if the signal is published without authorization, it can be traced back to the offending receiver.
