Introducing the Olevia TV
Technology Overview
Congratulations! You've just purchased the most advanced video processing
Television System available today. HQV represents an enormous leap in
video processing performance with true flagship de-interlacing, cadence
detection, noise reduction and scaling. Silicon Optix designed the HQV
processing engine as a no-compromise solution.
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.
Teranex was founded in 1998 to commercialize the Lockheed Martin technology.
Teranex's video-processing boxes sell for as much as $100,000 and are used
by the leading broadcasters around the world, including NBC, CBS, ABC,
FOX, and Warner Brothers.
In 2002, Silicon Optix and Teranex realized that semiconductor technology
had advanced enough that they could take the large Teranex video-processing
box and condense into an affordable single chip. In September 2004, the
Realta HQV video processor, which matches the performance of Teranex's
$60,000 video processor, was announced to the world.
HQV De-interlacing
HQV is a true pixel-based motion adaptive approach in which maximum
resolution is preserved. When both fields reach the HQV video processor,
a comparison is made with the previous two fields to determine which pixels
represent motion. HQV processing is careful to discard and interpolate only
the pixels that are necessary.
To recover some of the detail lost in the areas in motion, HQV processing
implements a second stage Multi-Direction Diagonal Filter that is able to
reconstruct some of the lost data by identifying edges of moving objects
resulting in smoother images more faithful to the original.
HQV Film Cadencing and Video/Film Detection
While the 2:3 cadence is the most common format used, it is only one of 8
cadences that are in use. Other cadences are necessary for other frame rates.
The range is wide, with animation being as low as 8 fps and documentaries
being as high as 30 fps.
Most competing video processors only look for a 2:3 pattern, and thereby
ignore all of the other cadences in use. HQV's flagship cadence detection
technology does not simply match incoming video against pre-programmed
patterns, but identifies frames simply as they arrive. This means that not
only is HQV processing able to detect all the cadences currently in use, no
matter how uncommon, but it will also be able to detect cadences that have
not yet been invented.
No matter what type of video you're watching or where it comes from, HQV
processing will always provide the best image.
