Dish Network™, the US Satellite Operator, approves Televes Watermarking on its suite of Clear QAM Encoders

Mar, 20/05/2014

Televes has received approval from Dish Network ( -one of the main TV Satellite Operators in the USA, with 14 million subscribers- for its Watermarking solution on its suite of Clear QAM Encoders. Watermarking is the process of hiding digital information to verify the authenticity or integrity of the signal or to show the identity of its owners. Televes Clear QAM Encoders offers invisible watermarking as an option for forensic video analysis in an effort to prevent piracy.

Juan Molezun, director of the International Division, said: “We are very pleased to have received approval of our watermarking solution from Dish Network. This is the next step in expanding the market for our professional quality encoders.”

All versions of Clear QAM Encoders provide Dolby Digital from analogue or digital inputs, closed captioning, EAS support, and include ASI input and output for easy EAS signal management, all with the innovative Televes integrated RF combiner. They encode both MPEG-2 and H.264 and offer the full remote control functionality that any T.0X headend module supports. For these reasons, they are ideal for any video distribution integration. “Be it for distributing full HD video cost effectively in the home or a commercial HD installation, our Clear QAM Encoder output distributed over standard coax, on any modern TV, provides top quality”, affirmed Molezun.

What is watermarking?

A digital watermark is a marker embedded in the image data. It is typically used to identify ownership of the copyright of such signal. “Watermarking” is the process of hiding digital information to verify the authenticity or integrity of the signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication. Like traditional watermarks, digital watermarks are only perceptible under certain conditions, for example using some algorithm (watermarking detection), and imperceptible anytime else for the naked eye. Since a digital copy of data is the same as the original, digital watermarking is a passive protection tool. It just marks data, but does not degrade it nor controls access to the data. 

In this case, Televes encoders hide the serial number of the Dish Network set-top box making it invisible to the human eye, but unalterable to any recoding or retransmitting from other video devices such as a camcorder. In case unauthorized publications, the Televes encoder recuperates the STB serial number to identify the source of the coded image.
