Chapter 13 - HD Video Processors
A good number of HD video processors were included on earlier State of H/DTV
Review reports. Many of those units are still available as current models from
companies like Lumagen, Center Stage, Cinemateq, Faroudja, Key Digital, etc.
Please consult the 2006 HDTV Technology Report and the 2005 HDTV Technology
Report for details on some of those previously released products.
I am listing first the companies that have created video processing
solutions/engines/etc, such as ABT, creator of the DVDO product, the Realta HQV by
Silicon Optix, and the VXP by Gennum. Following that group, I review
products/companies that have implemented those video processing solutions (or
their own) on their products.
Engines for Video Processors
ABT
Anchor Bay Technologies is the original creator of the award winning line of DVDO ®
iScan, the company demonstrated at CES a 1080i (to p) de-interlacing product
among other technologies. ABT’s HD de-interlacing technology includes detection of
interlaced video, which originated from any progressive source, motion, and edgeadaptive
de-interlacing for video sources as well as low latency options for video
gaming. ABT’s Precision Video Scaling technology was first deployed in ABT's DVDO
iScan HD. It has been incorporated into many hi-quality products such as the early
Marantz’s DV9600 and the DVD-5910 Denon's
flagship, DVD players.
The scaling engine is completely flexible,
accepting standard definition (480p, 576p) and
high definition (720p and 1080i) inputs and
outputting any resolution from VGA (640x480)
to 1080p (1920x1080) with multiple standard
and custom aspect ratios, and supporting other
image manipulation features, including zoom,
pan and border controls. ABT's high
performance frame rate conversion also
supports converting film sources from 24
frames per second to 48, 60 or 72 frames per second.
Some of the ABT technologies are:
VRS Precision Video Scaling II, Precision Deinterlacing, Progressive Re-
Processing (PReP), RightRate, AutoCUE-C, and Precision AV LipSync.
Progressive Re-Processing (PReP)
Improves video signals and removes artifacts caused by poor deinterlacing in source
equipment, restoring a video signal to its interlaced beginnings and is properly
deinterlaced using reference-quality Precision Deinterlacing, applying motion, edge
