Silicon Optix announces Realta with HQV technology, a single-chip video processor that brings Teranex’s $60k Hollywood Quality Video to the home entertainment and professional large-area digital display markets.
The Realta chip combines Teranex’s trillion operation per second broadcast quality video processing with Silicon Optix’s proprietary geometric scaling technology to create a new standard for image quality, a standard Silicon Optix is calling “Hollywood Quality Video,” or HQV.
Realta’s Hollywood Quality Video core technology includes Teranex’s software algorithms that have been refined through 100,000 hours of content verification over the past six years. Today’s hard-wired video processing chips attempt to support all types of displays with fixed average values which deliver an average picture quality. Realta’s programmability allows consumer electronics manufacturers to keep pace with newly developed content and optimize image quality for different types of display technologies such as Plasma, LCD, DLP, HTPS, D-ILA and LCOS.
Realta’s Hollywood Quality Video Processing includes:
HQV True 1080i to 1080p/QXGA De-interlacing: Rather than discarding half the resolution of high-definition (HD) images as today’s image processors typically do, HQV technology uses the full four-field processing window for HD video de-interlacing and cadence detection, preserving the rich details in HD imagery.
HQV SD/HD Multi-Direction Diagonal Filter: A true 10-bit diagonal interpolator that removes any stair-stepping artifacts from de-interlaced video sources without blurring the image.
HQV Noise Reduction: A fully automatic per-pixel adaptive software algorithm adds a new dimension of pixel-by-pixel noise and motion measurement, detecting and reducing the analog and MPEG noise that currently causes problems in DVD and broadcast sources, while maintaining full image fidelity.
HQV Detail Enhancement: Watching standard-definition (SD) images on HD displays can produce a blurring effect that results in a disappointing visual experience. HQV detail enhancement improves the image detail on a pixel-by-pixel basis, delivering SD that more approaches HD quality.
HQV Automatic Film Mode Cadence Processing: HQV processing provides support for “Vari-Speed” cadences such as 3:2:3:2:2 commonly used for movies broadcast on television, as well as 5:5, 6:4, and 8:7, cadences used for the many different styles of animation. HQV cadence processing ensures that users will always be viewing film and video sources in the original format without loss of resolution. HQV technology is first to offer 3:2 insertion at HD, an important requirement of the new HD Blu-Ray and HD-DVD formats coming soon to the consumer market.
HQV Automatic Per Pixel Video/Film Detection: Rather than making frame level decisions for video vs. film processing, causing artifacts to occur in sequences such as video titles and movie credits over film backgrounds, HQV makes pixel-level decisions, thus processing film pixels as film and video pixels as video.
HQV 16 to 1024-Tap Adaptive Scaling: Resolution up and down-scaling requires a large set of image samples to prevent the introduction of visually unacceptable artifacts. Realta delivers image scaling quality by providing the first 16 to 1024-tap adaptive over-sampling scaling engine to maintain the highest image quality.
True 10-Bit Processing: Realta offers complete input to output 4:4:4 color processing and a full 10-bit or better internal data path, enabling the rendering of over 1 billion colors.
Equal Quality Two Channel Processing: The Realta’s powerful image processing engines can process two full resolution channels of HD or SD, enabling equal image quality for each video window in PIP, PAP, and POP modes.
