Mosquito Noise Reduction
Video compression is a commonly used technique to squeeze more video content
onto a disc, or beam down more channels via satellite, or transmit more
channels over a cable. By using video compression content providers can
achieve better economies of scale and offer the consumer more video content
- e.g. more channels, bonus materials, etc. The problem with nearly all
video compression methods is that too much of it causes compression artifacts.
These artifacts are often seen by the viewer as ugly ringing around text
letters or noise - often called mosquito noise.
To counter this we have developed a proprietary method of selectively
removing mosquito noise. Unlike some methods of noise reduction that often
makes the image worse by removing too much detail or causing blurring
during motion, Mosquito Noise Reduction is designed to isolate the most
objectionable of artifacts without removing detail or causing motion blur.
To do this we had to devise a proprietary method of both isolating and
predicting areas in the image where this noise is likely to occur. The
end result is a highly effective noise reduction method that is impervious
to motion, yet, largely maintains the integrity of the detail in the image
through our conservative approach in removing video compression artifacts.
With Mosquito Noise Reduction
Fine Detail & Edge Enhancement
Sharpness controls are not new in the world of video - nearly every TV
sold in the last 20 years features a sharpness control. However, sharpening
controls merely accentuate medium detail at the expense of fine detail
and often add horrible "halos" around the edges and lines. While this
trick was a reasonable approach for standard definition TV, when screen
sizes were well under 30 inches, today's large screen TVs and HDTVs have
made traditional sharpness controls highly undesirable since the damage
they cause is now magnified with such larger screens. In addition, traditional
sharpening controls tend to exaggerate any noise in the image by making
it more pronounced so noise becomes even more pronounced when viewed on
a large screen HDTV.
Fine Detail & Edge Enhancement was designed with large screen HDTVs in
mind. Using patent pending technology, Fine Detail & Edge Enhancement
is able to isolate areas of the image where hard edges are prevalent and
increase fine details without adding halos or ringing. The net effect
is quite extraordinary - images have more "pop" and fine detail such as
blades of grass or even the pores on an actor's face are drawn out making
your large screen HDTV even more enjoyable. Moreover, Mosquito Noise Reduction
can be used to remove objectionable ringing and noise in the image before
using Fine Detail & Edge Enhancement to draw out the fine details in the
With Fine Detail Enhancement
With Edge Enhancement
Our 10-bit Precision Deinterlacing of standard and high definition video
delivers the image quality demanded by today's large-screen, high-resolution
displays. It eliminates many of the artifacts found in common deinterlacers
to produce a smooth image, free of artifacts such as jagged edges and
combing. Precision Deinterlacing features five-field motion-adaptive deinterlacing
and edge-adaptive processing for video sources, along with advanced cadence
detection for film and animation sources. All processing is performed
at full 10-bit resolution to preserve all the detail and subtle nuances
in the video source. Edge-adaptive processing uses an adaptive, continuous-angle
detection algorithm to accurately identify and smooth image edges.
Unique, "any-cadence" processing automatically locks to the wide variety
of film and animation cadences found in current video sources, including
non-standard cadences, and will track right through many types of "bad
edits" and cadence changes. Precision Deinterlacing also features “Game
Mode” with low-latency processing for maximum “playability”.
Precision Video Scaling™
Our latest 10-bit Precision Video Scaling technology is based on our proprietary
video scaling engine that can independently scale an image horizontally
and vertically to achieve an outstanding picture quality for today's high
resolution video displays. The scaling engine is completely flexible,
accepting standard definition (480p, 576p) and high definition (720p,
1080i and 1080p) inputs and outputting the most popular resolutions from
VGA (640x480) to 1080p (1920x1080). Since the scaling engine is completely
flexible, other image manipulation features are also supported including
zoom and pan. Non-linear stretch or panorama mode is also supported for
4:3 images that need to fill 16:9 displays without showing borders.
PReP®, Progressive ReProcessing
Progressive ReProcessing (PReP®) is the video processing industry's
first processing method that significantly improves progressive video
signals and removes artifacts caused by inferior interlaced-to-progressive
Video signals that originate in an interlaced format are often degraded
by artifacts incurred when the signal is converted from interlaced to
progressive formats by general purpose chips in DVD players, AV receivers,
and set-top boxes. Until now, there has been no way to improve these signals
to optimize images on high-resolution displays. Poor interlaced-to-progressive
conversion is especially problematic with large-screen HDTVs, as upscaling
to higher resolutions often amplifies artifacts created in the conversion
process, making them more noticeable.
As a solution to this problem, we introduced PReP, an advanced video processing
technology that reverts the progressive video signal output from source
equipment to its original interlaced format. PReP then converts the interlaced
signal to progressive format, this time applying the source, edge, and
motion adaptive algorithms in its Precision Deinterlacing™ technology
to eliminate jaggies, combing, and other degrading effects. In EDGE Green,
PReP technology allows 480p and 576p formats to be processed by this method.
Progressive Cadence Detection™
Film-based content, which originated at 24 frames per second, is broadcast
at 50 or 60Hz. Progressive Cadence Detection can lock on to the original
3:2 cadence in the broadcast, reacquiring the original 24 frames per second.
This signal can then be output at a source-locked 24Hz eliminating the
judder that existed in the original broadcast signal. Progressive Cadence
Detection can be used with 480p, 576p, 720p50, 720p60 1080p50, 1080p60
RightRate technology converts the input frame rate to the optimal display
frame rate without causing 'tearing' in the output frame. High performance
frame rate conversion also supports converting film sources from 24 frames
per second to 60 frames per second for NTSC format and from 25 frames
per second to 50 frames per second for PAL/SECAM format.
AutoCUE-C technology automatically detects and removes chroma artifacts
that are caused by incorrect upsampling of the chroma (color) signals
by MPEG decoders in DVD players and satellite receivers. These artifacts
are especially noticeable as horizontal streaks in images with highly
saturated colors. When the artifacts are removed, the resulting picture
quality is significantly improved, providing a much clearer and true-to-life
Precision AV Lipsync™
Precision AV LipSync technology is designed to automatically delay the
audio signal to match the video processing delay in other DVDO products.
As a result, the AV Lipsync problem that is caused by video processing
delay is eliminated. If required, the audio delay can also be further
adjusted to correct any AV Lipsync problem that may be already be present
in the AV source.
- What is 'Game Mode'?
This mode can reduce the amount of video delay to less than a single frame.
In many competitive processors the effects of applying complex algorithms
to the video image results in upwards of a seven frame delay. This can
inhibit the real-time performance for gamers who want instantaneous response
to react to stimuli and to realize peak performance from their application.
The VRS Precision Deinterlacing™ Game Mode will reduce frame delay
down to slightly less than one frame of video.
- What signals can the EDGE Green output?
EDGE Green has one HDMI 1.3 output that outputs both audio and video.
The second HDMI output only carries audio, with blank 720p video, which
is intended to carry audio to a connected Audio/Video Receiver. If your
source has a DVI output (and no HDMI output), a DVI-to-HDMI adapter or
cable will be needed to connect this source to the EDGE Green. The same
is true, if your display does not have an HDMI input, but does have a
DVI input. DVI does not carry audio, so for DVI sources/displays an alternative
method of connecting audio must be used.
EDGE Green can automatically determine and output the ‘preferred’ format
of the display by reading the EDID of the connected display. Some displays
do not report the correct information in which case, the user can select
one of the available output formats including 480p, 576p, 720p50/60, 1080i50/60,
- Tell me more about the HDMI connections on EDGE Green
There are five HDMI inputs on the EDGE Green. The HDMI inputs on EDGE
Green can process 480i/p-60, 576i/p-50, 720p-50/60, 1080i-50/60, 1080p-24/25/50/60
and VGA/SVGA/XGA/SXGA@60Hz. The HDMI input and output connectors on the
EDGE Green are backwards compatible with DVI-D inputs and outputs when
used with an HDMI-to-DVI adapter or cable. Please note that DVI is a video-only
connection that does not carry audio so an alternative method of connecting
audio must be used.
Note that if you have an HDCP source and a non-HDCP display, you will
probably not get a picture, whether or not you use EDGE Green.
- What kind of aspect ratio control does the EDGE Green offer?
EDGE Green offers full control over the input aspect ratio. There are
4 predefined input aspect ratio settings:
4:3 Full Frame: to watch 4:3 content while preserving the aspect ratio
4:3 Letterbox: to watch 4:3 Letterbox, non-anamorphic, content full screen
with no geometric distortion on a 16:9 display.
4:3 Non-Linear Stretch (Panorama): to watch 4:3 content stretched to fill
a 16:9 display. In this mode, the image is distorted such that most of
the stretching occurs at the side of the image, not the center.
16:9 Full Frame: to watch 16:9 anamorphic content while preserving the
aspect ratio. This mode can also be used to watch 4:3 content on a 16:9
screen, although the image will be stretched horizontally
You may also use the zoom and pan controls to customize the input aspect
ratio to your tastes. This allows the user to reformat the image in any
way desired, so the EDGE Green doesn't enforce a set of fixed aspect ratios.
If you would like to zoom in on the image to remove the small black letterbox
bars found with a 1.85:1 source on a 16:9 display, then you can simply
do this with the direct access ‘Zoom -/+’ controls on the remote control
or via the graphical user interface, GUI.
- What audio formats can the EDGE Green support?
EDGE Green has three audio outputs: the HDMI audio/video output, the dedicated
HDMI 1.3 audio only output and the optical digital output. If a source
connected using HDMI is outputting high bit-rate audio, Dolby TrueHD or
DTS Master Audio, and EDGE Green is connected to an AV Receiver or Processor
that supports these formats they will be passed through with the proper
amount of delay to be in sync with the processed video. If the optical
output is used with a source that supports high bit-rate audio, EDGE Green
will communicate with the source to output an audio format that the optical
connection is capable of carrying, stereo PCM or Dolby Digital/DTS. Audio
that is input via the analog inputs can be output over HDMI or optical.
There are some HDMI sources that do not output the correct audio signal
when connected to an HDMI repeater, like an AV receiver or video processor.
In these instances, we recommend that use an alternative method of sending
audio, like the optical or coaxial digital audio outputs.
The audio section of EDGE Green supports S/PDIF and PCM formatted audio
with sample rates ranging from 24kHz to 192kHz. It will likely handle
sample rates beyond this range, but is only guaranteed to support sample
rates within this range. The EDGE Green will pass digital audio having
any bit-depth resolution up to 24 bits, at all supported sample rates.
EDGE Green will also pass compressed digital audio (e.g. Dolby Digital
or DTS) provided the audio bitstream has been properly formatted for S/PDIF
(IEC60958 or EIAJ-CP1201 standard) transmission by the digital audio source
(according to international standard IEC61937). The EDGE Green does not
alter the sample rate, format, or content of the digital audio whatsoever;
it merely inserts a programmable delay into the transmission path.
Users should take care to use proper digital audio cables in order to
guarantee valid audio reception and re-transmission. Both coax and optical
cables should have high-quality, positive mating connectors at both ends.
Coax cables should have a 75-ohm characteristic impedance. The use of
couplers or other types of adapters to extend the digital audio cabling
is not recommended.
- Tell me more about the lipsync correction on EDGE Green
EDGE Green has 4 discrete digital audio inputs (3 optical and 1 coaxial)
and 1 analog audio input (L/R) each of which can be assigned to any of
the video inputs. The HDMI 1.3 inputs can also accept audio, if the video
signal is on the same input. EDGE Green is also compatible with high bit-rate
audio, like Dolby TrueHD and DTS-Master Audio. If the incoming HDMI signal
has HDCP, then EDGE Green can not output this audio using the optical
or coaxial digital outputs, only the HDMI output. When you switch to a
particular video input, then the audio input which has been user-assigned
to that video input will also be selected. For example, when you switch
to Video, then the audio input which has been user-assigned to Video will
also be selected.
The digital audio outputs provide a delay which matches the video processing
delay of EDGE Green. Note that this delay will vary depending on the current
configuration and processing mode of EDGE Green. 50 Hz sources will require
a different amount of delay than 60 Hz sources, and frame rate conversion
requires more delay than no frame rate conversion.
The correct audio delay for all inputs is set automatically, so you need
to do nothing extra to match audio and video delays. In addition, there
is a user-adjustable delay which can be added or subtracted on top of
the automatically set delay for problem sources.
Our digital audio technology is called "Precision AV Lipsync™".
- Does EDGE Green have an On Screen Display (OSD)?
Yes, there is a very intuitive OSD that allows you to control all of the
major parameters: output resolution, aspect ratio, picture controls, and
audio delay. There are hints available with all controls to assist inexperienced
- How does EDGE Green detect incoming signals?
EDGE Green has been designed to detect which of the ten possible input
devices is turned on and is generating an active signal, and then to automatically
switch to that input. With this capability, you can switch inputs simply
by turning one input device on or by turning another device off.
EDGE Green also includes an "Input Priority" option which specifies which
of the inputs to use when they are multiple active inputs.
- What kind of power supply does EDGE Green have?
The EDGE Green comes with a universal internal power supply, which accepts
100-240 VAC at 50/60Hz.
- Will the EDGE Green improve
the picture quality of standard definition channels from my satellite
Picture improvement of heavily compressed standard, and even high, definition
satellite channels is often very subjective, and depends to a great deal
on exactly which aspects of the image are objectionable. The EDGE Green
does incorporate three new technologies that do specifically address this
issue: Mosquito Noise Reduction, Fine Detail Enhancement and Edge Enhancement.
One artifact of compression is mosquito noise. This kind of compression
noise is apparent along the edges of compressed images, especially text.
Our Mosquito Noise Reduction can significantly reduce this noise providing
an appreciably better picture. Additionally, our Fine Detail Enhancement
can extract fine details in the image that were masked by this compression.
Finally, our Edge Enhancement can improve the perceived sharpness of the
image without adding additional ringing.
