iScan Mini - Adaptive 4K UHD Picture Enhancement in a Hide-Behind-the-TV Package
4K Ultra HD TVs are now readily available and deliver pristine video resolution with 8 million pixels. However, with
the exception of some proprietary media players, most of today’s content is not native 4K, but available on DVD and
DVDO iScan Mini

DVDO iScan Mini - 4K Scaler / Video Enhancement
Blu-ray discs or streamed over the Internet in a highly compressed format. Artifacts generated from compression or
the use of low quality scalers can result in reduced picture quality. iScan Mini is specifically designed to
automatically upscale both SD and HD sources up to 4K resolution while enhancing original source content. Other
key features also include video setup and adjustment tools, EDID editing, and S/PDIF digital audio output . In
addition, the iScan Mini’s small package size enables a clean set up, which can be placed behind an existing A/V
Receiver, Video Processor or even wall mounted TV.
VRS® ClearView™ Technology: Video Processing
VRS ClearView technology has powered many generations of DVDO’s video processors and other home theater
products. The iScan Mini features the latest generation of VRS ClearView technology including advanced 4K scaling as
well as enhancement technologies to remove jaggies and mosquito noise from poor quality sources, while at the same
time increasing the depth and clarity of images, making any video pop.
iScan Mini sharpens Blu-ray-quality video, bringing out details and nuances not visible in the original content. It also
incorporates picture enhancement presets designed for those who prefer ease of use and also provides all the necessary
controls to save multiple custom settings. Since SD and HD video require different enhancements, iScan Mini
automatically switches between enhancement presets based on the input video type.
Demo Mode:
A unique split screen demo mode is available allowing you to easily see the before and after for video enhancements.
Two different sweep modes let you pause an image and the sweeping bar enhances the video as it sweeps across.
VRS ClearView Technology: Adaptive Scaling
VRS ClearView Technology features 4K adaptive studio quality scaling for discerning videophiles with large screen
displays or projectors. iScan Mini’s state-of-the-art 4K scaler will scale video and graphics optimally, bringing out details
without any ringing on text or around black-bars, unlike embedded scalers in many displays or source devices.
DVDO iScan Mini

DVDO iScan Mini - 4K Scaler / Video Enhancement
iScan Mini provides three scaling modes:
-
Auto mode scales anything up to 4K or the best resolution the display can handle
-
DVDO mode scales compatible frame rate input video to a manually chosen resolution for those who want more
control
-
Off mode disables the iScan Mini’s scaler (set to 1:1 mode) while keeping other processing active
The iScan Mini works just as well with 1080p displays, scaling and enhancing SD and 720p content, bringing out hidden
details, and correcting mosquito artifacts and compression noise from your SD and Internet streaming sources.
Display Setup
iScan Mini enables basic display setup by providing the test patterns necessary to adjust brightness, contrast, sharpness,
color/saturation levels, over scan, and resolution verification. For full 4K display set up including professional color
calibration, DVDO’s AVLab TPG™ (test pattern generator) is recommended. The detailed setup instructions provided in
the user’s guide will allow any display to be quickly adjusted for optimal viewing.
EDID Editing
Not all TVs report their capabilities correctly and sometimes professional installers want to force a specific video format. In
particular, 4K is a new technology and not all displays handle it the same way. On-screen EDID editing capabilities allow
the professional installer control to fix incompatibility issues.
Digital Audio Out
Have a soundbar or older A/V receiver that doesn’t support HDMI®? iScan Mini will send audio from its HDMI or MHL
input to its S/PDIF output in auto, stereo PCM, or AVR compatibility mode.

Enhancements:
The Enhancement menu provides access to video
adjustments, video processing settings, and allows the
user to recall or save custom enhancement settings.
All settings in this menu can be adjusted and saved to two
User memories.
All video and processing settings are described below
Enhancement Mode – selects the current enhancement
setting (Low, High, User 1, User 2, Off)
Recall – User can recall any saved memory (Low, High,
User1, User2) and the contents of that memory are
displayed on the controls in the menu below.
Save – Once a memory is recalled and then changed to get the best possible performance, the user can save the settings
into User1 or User2 memory location.
** NOTE: Because Standard Definition [SD] and High Definition [HD] content require different settings, iScan Mini
automatically switches between two memory sets based on what kind of video is present on the input. So there are
actually 8 memories; Low(SD), Low(HD), High(SD), High(HD), User1(SD), User1(HD), User2(SD), User2(HD). If the
current input is SD (480 or 576) and you choose recall User1, it will recall User1(SD). If the current input is HD (720-4K)
and you choose save>User1 it will save current settings into User1(HD). The Current SD/HD mode is shown at the bottom
of the menu when Enhancement mode is highlighted.
If you recall any memory and make any changes to those settings, the current mode changes automatically to Manual.
To keep the new settings you must save them into a User location.
During normal operation, if you have User1 enhancement mode selected (either by using the remote to select it directly or
using the OSD), iScan mini will apply the corresponding enhancement memory based on the input type; User1(SD) if an
SD signal (480 or 576) is present and User1(HD) if an HD signal (720 up to 4K) is present.

DVDO iScan Mini - 4K Scaler / Video Enhancement
Enhancement Controls:
The input type determines which controls apply to the video signal.
Brightness, Contrast and Color apply to all video types and can be adjusted using the built-in test patterns.
Brightness
Adjusts the black level of the overall image from the iScan Mini. When you make an adjustment to brightness, all
video levels, from black to peak white, are shifted up or down. Brightness is also known as Black Level adjustment.
Contrast
Video contrast works by adjusting the level of white. Contrast is complimentary to the Brightness control. Contrast
controls should be used carefully because if overly adjusted, some details in lighter areas can become less visible.
Color (Saturation)
Color refers to the mix of “color” vs. “brightness” in the picture. Increasing Color makes colors look more vivid.
Decreasing Color makes colors look “washed out.” Changes to either Brightness or Contrast can change your
Color Saturation. You can use this control to balance the mix of color in an image.

DVDO iScan Mini - 4K Scaler / Video Enhancement
Mosquito & Internet Noise Reduction will only affect SD video types and is used to reduce the effects of mosquito noise
and video compression artifacts. Mosquito Noise is a type of image noise that is caused by video compression in cable,
satellite and broadcasts. It is typically visible on SD content as a fuzzy ‘halo’ around object edges. Use higher setting for
noisier images.

DVDO iScan Mini - 4K Scaler / Video Enhancement
SD Smoothing will only affect SD video types and is used to reduce “jaggies” present in low resolution video before the
signal is scaled
DVDO iScan Mini
16
DVDO iScan Mini - 4K Scaler / Video Enhancement
Detail Enhancement will affect both SD and HD video types and is used as an overall enhancement much like the Adobe
unsharp mask. It sharpens fine aspects of the picture on a pixel by pixel basis. A high setting can make crisp images
appear almost 3D and sharpen fine granular detail.
No Enhancement
Detail Enhancement
Edge Enhancement
Edge Enhancement will affect both SD and HD video types and is used specifically to sharpen object edges. This control
is especially useful if you have a noisy image but you still want to sharpen the image... This example with the control at
maximum enhances fine details (notice the lace is now crisp, individual teeth can be seen) and the main image is given a
slight shadow making it appear almost 3D. (Face enlarged to see the detail)

DVDO iScan Mini - 4K Scaler / Video Enhancement
Ringing Suppression will affect both SD and HD video types and is specifically used to reduce ringing in high contrast
areas of scaled video such as around black bars, text and graphics. The iScan Mini’s adaptive scaler will suppress
ringing around scaled text and graphics while preserving the resolution of the natural video content. See the example
below. Using ringing suppression, scaled video will look clean and smooth while maintaing detail.
Ring Suppression OFF

DVDO iScan Mini - 4K Scaler / Video Enhancement
HD Smoothing will affect SD or HD OUTPUT video types and is specifically used to smooth jaggies that occur around
object edges after the video is scaled. The jaggies are very visible when the scaling ratio is large. In the example below
the video is scaled from 480 to 1080. On the left you can see the jaggies created and on the right smoothed.
DVDO iScan Mini

DVDO iScan Mini - 4K Scaler / Video Enhancement
Scaling Modes
From the scaling menu, you can choose one of three modes:
 Auto Mode: iScan Mini reads the capability of the TV
(EDID) and passes that back to the current source. Once video
is sent from the source, Mini determines if it can be scaled up to
the native resolution of the display with the same frame rate
(auto is always 1:1 frame rate). If something is provided that
cannot be scaled, it is simply passed through with a warning
message.
Example: input 480/60 – output 4K/60
Input 1080/24 – output 4K/24
 DVDO (Manual) mode: When activated, you can choose
a preferred output resolution. The entire display capability
(EDID) is passed back to the source and if the input can be
scaled to the preferred output it will be, if not it is passed
through. DVDO mode is always a 1:1 frame rate so only
identical frame rates are scaled.
Example: set output to 4K60
Input 720p/60 – output 4K/60
Input 1080p24 – output 1080p24 (pass through)

Off mode: no scaling, output = input
*** Note: iScan Mini does not deinterlace or perform Frame Rate Conversion.

Modify EDID
Basic display EDID editing is provided to allow forcing of specific resolutions by a professional installer. Modifying an
EDID can result in improper or unexpected operation or no picture or audio. Please use this only if you are comfortable
with EDIDs and have modified them before.
Procedure for modifying EDID is:
1. Capture EDID from display
2. Modify EDID as needed – The on screen menu allows you
to remove resolutions but not add them. (Adding a resolution can
result in no picture)
3. Save EDID to memory
4. Choose “Use Saved” in the EDID Mode selection
To use the TV ‘s EDID again, choose “Use TV

Demo Mode: This is a special mode that allows you to quickly see the results of applied enhancements. Split screen
shows no enhancements on the left side and applied enhancements on the right.
Slow and Fast moving bar also show applied enhancements on the left and no enhancements on the right. So as the ar
sweeps across the screen it updates the picture real time. Note that enhancements are easier to see and adjust with a still

Audio Output to S/PDIF
If there is a need to extract audio from the HDMI stream and output to S/PDIF instead (e.g. Soundbar, DVI only TV, or
whole home audio feed), the iScan Mini optical S/PDIF audio output can be used.
Note that while iScan Mini does not have an audio processor, the Audio menu does allow you to modify the audio part of
the EDID so that the proper audio for your application can be requested from the source.
Auto Mode makes no modification to the audio portion of the
EDID presented by the attached display. Since most displays
only have stereo PCM in their audio EDID, That is what the
source will send. If you connect the optical S/PDIF to an AVR or
soundbar, only stereo audio will be heard. Also, if the TV asks
for True-HD audio (incompatible with S/PDIF) there will be no
output from the optical S/PDIF output.
Custom mode allows you to select a specific audio format to
request from the source. When activated, the audio portion of
the EDID from the TV is completely removed and replaced with
the selection in the next menu.
Custom S/PDIF can be selected to be PCM/2, meaning stereo
PCM only or you can select AVR which applies a full selection of audio formats that most AVRs and soundbars are
capable of decoding.
AVR selection includes AC-3/DTS 5.1 and 2 channel PCM

Test Pattern Explanations
Frame & Geometry
This test pattern contains two specific test features. The first is a 1-pixel wide box around the very outside
of the image. This is used to determine when the entire iScan output image is visible on the display. The
arrows along the middle of each edge provide an indication of the amount of overscan (if any). The blue
boxes in the center of each quadrant are used for measuring display geometry. The rectangle in the
center of the gray boxes should appear square on a 4:3 aspect ratio display, the next large rectangle
should appear square on a 16:9 display, the next on a 1.85:1 display, and the largest rectangle should be
square on a 2.35:1 display. The blue boxes are also used as an indication that the horizontal positioning
of the output image is correct. This is particularly useful to align a video projector and also to visually
verify that a TV is not in overscan mode. If the blue boxes are displayed as red instead of blue, then the
Cb & Cr components are reversed. This can be corrected by ensuring that there is an even number of
pixels in the sum of the horizontal sync and horizontal back porch.
Frame/Geometry Test Pattern Displayed Correctly (Image B)
When this test pattern is displayed correctly, it should look like this, with a one-pixel wide white border
around the edge of the screen:
DVDO iScan Mini
27
DVDO iScan Mini - 4K Scaler / Video Enhancement
Frame/Geometry Test Pattern (Image C)
As you can see in image C, the test pattern is almost displayed correctly. You can see the 1-pixel wide
white border on the top, bottom and left side of the image but not on the right side of the image. By
adjusting the horizontal size of this signal to 1360 (rather than 1366), we can get this test pattern
displayed correctly on our display.
Vertical lines, Horizontal lines, and every other pixel:
There are three test patterns that are used to verify that the chosen output resolution is the native
resolution of your display and that you are bypassing any internal processing in your display.
When the every other pixel test pattern is displayed correctly, close up you should be able to see a 1pixel checkerboard and at proper viewing distance the image should appear as an even gray.
When this test pattern is displayed incorrectly, the resulting image does not look like a fine checkerboard
and may have irregular patterns. If this is the case then the chosen output resolution may not
DVDO iScan Mini
28
DVDO iScan Mini - 4K Scaler / Video Enhancement
be the native resolution of your display or your display may scale all input signals even if the input
resolution is already at native resolution.
Note: If this test pattern does not appear as it should and you have chosen the native resolution of your
display, you may not be able to bypass the internal processing on your display.
The ‘Vertical Lines’ test pattern should appear as one pixel wide black and white columns. If you see any
irregular pattern(s) in the image then you know that the display is scaling the signal horizontally.
If using a projector, the vertical lines will show distortion if any keystone is used. Keystone should be
avoided at all costs – instead, hang the projector in the correct position.
The ‘Horizontal Lines’ test pattern should appear as one pixel tall black and white rows. If you see any
irregular pattern(s) in the image then you know that the display is scaling the signal vertically.
Judder (Frame Rate)
The Frame Rate Conversion test pattern consists of a vertical bar which moves slowly back and forth
across the screen. The bar’s motion is updated once in each output frame period of the IScan Mini, and it
moves a fixed number of pixels horizontally in each frame period. This moving bar test pattern is intended
to identify the frame rates at which a display will operate. If the display is not performing any frame rate
conversion, i.e., it is actually displaying the output frame rate of the IScan Mini – the motion will be very
smooth. However, if the display is performing any type of frame rate conversion there will be very
noticeable stutter introduced in the smooth motion. There may also be other objectionable artifacts
introduced depending on how the display actually performs the conversion. These include tearing (top and
bottom portion of the bar are horizontally misaligned) and distortion.
DVDO iScan Mini
29
DVDO iScan Mini - 4K Scaler / Video Enhancement
PLUGE patterns (2 white and 2 black)
These patterns are used to visually adjust brightness (black level) and contrast (white level) as well as to
verify the display is in the correct color space mode.
RGB video is normally sent using all 256 bits (in 8 bit color)
but YCbCr (component video) sets black at 16 and white at
238. This allows room above and below the active video for
below black and above white. PLUGE patterns are
specifically designed to allow quick visual setting of the
black and white level.
Using the black patterns (background is 16) so set the
brightness level on the TV until you can just see the
difference between 16 and 17. Depending on how fine the
display adjustment is, you may not be able to get this
exact, but 16 should be black and 17 grey. Everything below 16 should not be distinguishable. Having this
setting correct will bring out the details in dark pictures.
Using the white patterns (background is 238) set the contrast level on the TV until you can just see the
difference between 237 and 238. Many LED and LCD TVs will not have enough contrast range to allow this
to be set completely correct, and it is normally improper to set contrast to very high values. So it you
cannot make everything above 238 clip (disappear) then set contrast to around 75% and double check
using a dynamic range sweep with CMS software.

DVDO iScan Mini - 4K Scaler / Video Enhancement
Brightness & Contrast
This test pattern is composed of 4 quarter-screen
blocks. Two of the blocks have a background level of
standard black, and the other two blocks have a
background level of standard white. Embedded in
the black blocks are 3 bars. One is 4 IRE below
black, one is 1 IRE above black, and the third is 2
IRE above black. Embedded in the white blocks are 3
bars.
The ‘Brightness/Contrast’ test pattern will assist you
in setting up both the brightness (black level) and
contrast (white level) of your display. The
‘Brightness/Contrast’ test pattern is composed of 4
quarter-screen blocks. Two of the blocks have a
background level of standard black and the other
two blocks have a background level of standard

is 4 IRE below black (blacker-than-black), one is 1 IRE above black, and the third is 2 IRE above black.
Embedded in the white blocks are 3 bars. One is 1 IRE above white (whiter-then- white), one is 1 IRE
below white, and the third is 2 IRE below white. The bottom two blocks differ slightly from these levels.
For the bottom two blocks, the blacker-than-black is at the lowest possible luma level and the whiterthan-white bar is at the highest possible luma level. When the brightness and contrast are adjusted
correctly, you should be able to see the 1 IRE and 2 IRE above black bars on the black background and
the 1 IRE and 2 IRE below white bars should be visible on the white background. When the brightness is
adjusted correctly, black objects should appear ‘black’ with the details still intact and lighter areas should
DVDO iScan Mini
31
DVDO iScan Mini - 4K Scaler / Video Enhancement
be ‘light’, not gray, with the details still intact. When the contrast is adjusted correctly, white objects will
appear ‘white’ with the details still intact. Because the contrast settings can affect brightness settings we
recommend that you check the brightness setting after making this adjustment.
Note that the ISF PLUGE patterns are also an efficient way to set brightness and contrast.
Color Bars: (8 iRE75, 8 IRE 100, 8x3)
The ‘Color8 Bars75’, ‘Color8 Bars100’, and 8x3 will assist in setting up the
saturation (color) and hue (tint) of your display. The ‘Color8 Bars75’ test
pattern consists of 8 vertical bars across the screen at a 75% saturation level.
The ‘Color8 Bars100’ test pattern consists of 8 vertical bars across the screen
at a 100% saturation level.
From left to right the bars are: grey, yellow, cyan, green, magenta, red, blue,
and black. To properly adjust the saturation and hue you will need to either
set your display to “blue only” mode or use a blue colored filter held in front
of your eyes. You will also need to turn off any automatic flesh tone controls on your display before
making these adjustments.
Adjust Chroma/Color/Saturation control so the outer bars (and small bar
under it “A” ) blend into each other, then adjust Tint/Hue so that the inner
bars “B” blend into each other. When the Saturation and Hue are adjusted
correctly, the white bar and the blue bar should be exactly the same shade

A when looking through the blue filter. Saturation and hue settings interact
with each other so after making this setting you may want to go back and

check that the saturation setting is correct.

Grey Ramp
The ‘Gray Ramp’ can help verify that your display is showing the
gradients between black and white correctly. You should see a
smooth transition between black and white with this test pattern.
This test pattern is a horizontal gray ramp. There is a black level (0
IRE) vertical bar along the left of the pattern and a white level (100
IRE) vertical bar along the right side of the pattern. Between the two
bars is a monotonic gray ramp which ranges from the minimum
luminance level (i.e., blacker than black) at the left to the maximum
luminance level (i.e., whiter than white) at the right. The minimum level of the ramp is a 10-bit digital
value of 4 (equivalent to an 8-bit value of 1); the maximum level of the ramp is a 10-bit value of 1020
(equivalent to an 8-bit value of 254).
If iScan Mini is set to 8 bit color depth, and you are using YUV video, that means there are actually only
222 (238-16) luminance steps being sent to the display. The display then interpolates and smooths these
steps to attempte to display something smooth across the screen. How much banding appears on the grey
ramp gives an indication as to the video processing capabilities of your display. If the banding is
noticeable, then either using deep color (10 or 12 bits) assuming your source and content is compatible or
adding a high quality video processor like the DVDO iScan Duo is an excellent solution.
** Note: Grey ramp is only available if the output is set to YC

Solid colors
These patterns are normally used with a color meter and software to read specific color levels. IRE stands
for International Radio Engineers and it is a relative scale, NOT an absolute. It defines the volt peak
to peak video divided up into 140 IRE units. This is done to make numbers for luminance levels easier to
communicate. In the ISF Training Manual, it is described as the amplitude of the video signal from
blanking (zero volts) to peak white is 0.714286 volts or 100 IRE units. Synchronization signals extend
from blanking to -0.285714 volts or -40 IRE units.
XHatch (coarse, fine, and focus):
Use this pattern to help adjust the lens on your front projector. You will also want to make sure that the
focus is optimally adjusted. We have included one test pattern designed specifically for this application. On
some displays, these settings, may not be available unless you get into the service menu. We recommend
that you hire an ISF-certified technician to make these adjustments.

Sharpness
As its name implies, sharpness is used to adjust the sharpness control on a display. If sharpness is set too
high, then single pixel black or white lines on a grey
background will appear to have a halo.
The top left of this screen (labels do not appear on the
actual pattern) has a 1 pixel black cross and nearby single
pixel white lines. Wider lines can be used to see the effect of
sharpness control on larger video structures.

Troubleshooting:
Issue:
Possible Resolution:
No picture or TV
reports signal not
supported
iScan Mini is putting out a resolution or bit depth that the TV cannot
handle. Press the button on the side of the Mini marked “scaling” until
auto appears and a signal returns.
Grey Ramp
and/or Frequency
Sweep cannot be
selected
These patterns are only available in YC modes – please provide a YCbCr
input to switch to this mode.
Cannot change to
RGB or YC444 or
deep color when
in 4K/60 mode
iScan Mini has a maximum output frequency of 300MHz so when in 4K/60
mode, only YC 4:2:0 8 bit is available. The OSD prevents user from
making changes when in 4K/60 mode.
Will not scale
from 1080p24 to
4K60
iScan Mini does not have a frame rate converter – so whatever the frame
rate is on the input (in this case 24), that has to be the frame rate of the
output.
I set a specific
resolution (e.g.
4K/60) but
sometimes iScan
scales and
sometimes it does
not
iScan Mini does not have a frame rate converter – so in auto mode, it
automatically adjusts the output to match the input, and in DVDO
(manual) mode, if will scale to the selected resolution/frame rate if it can,
but if it cannot it just passes the input through with no scaling so that the
display can scale.
