In order to convert all incoming video signals to the native resolution of a particular fixed-pixel display, manufacturers must incorporate a video-processing chip inside the display. In addition to scaling the image to fit the native resolution, this video processor is normally designed to enhance the image and remove artifacts caused by the conversion and transmission of video. Surprisingly, the video processor can make a significant difference in overall picture quality, even with true high-definition program content.

Unfortunately, video-processing technology has not kept up with the picture quality of today's larger and larger HD displays, which magnify the image defects that are caused by poor video processing. And although every high-definition display has a video processor, only the highest-quality processor can retain all of the nuance, detail, and intent of the original source. Since video processors can range from a rudimentary $10 chip used in the lowest-end products to $70,000 refrigerator-sized boxes used in Hollywood production houses, the video processor plays the most significant role in picture quality today.

History of the Technology

The roots of Silicon Optix HQV processing go back to the early 1980s, when Lockheed Martin developed it for military image and video processing. In the 15+ years of development by Lockheed Martin, over $100 million was invested in the technology, and 13 patents were issued.

Teranex was founded in 1998 to commercialize the Lockheed Martin technology. Since then, six additional patents on hardware, software, and algorithms have been filed thanks to the extensive work of Teranexs premier engineering team.

The company soon realized that the digital-media industry is particularly suited to the benefits of the technology. Teranexs video-processing platforms sell for as much as $100,000 and are used by the leading broadcasters around the world, including NBC, CBS, ABC, FOX, and WB, along with others in Japan, Australia, China, and South Korea.
