• Push Up and Down to increase or decrease the setting.
• Push Exit again to exit this mode.
Video input signals are usually classified in the following two ways:
•Frame Aspect Ratio
• Active Aspect Ratio
Note:
The Zoom and Pan functions are applied to the input signal, not the output. This is an important consideration,
especially for the Pan function. For example: If you do not zoom a full frame image more than 100%, there is nothing
to pan. However, if part of the image is not on the screen, then the Pan function will work.
The DreamScaler 4’s menu is exit automatically after 30 seconds of no user interaction.

Frame Aspect Ratio
Frame Aspect Ratio (FAR) consists of two possible ratios: 4:3 or 16:9. DVD discs encoded in a 16:9 frame are
sometimes referred to as anamorphic or enhanced for widescreen TV’s. For example, a non-anamorphic
widescreen DVD has a FAR of 4:3.
Active Aspect Ratio
Active Aspect Ratio (AAR) is the aspect ratio of the image or content (movie). This content is typically stated on the
back cover of DVD discs. Some common active aspect ratios are as follows:
• 1.33:1 (4:3)
• 1.55:1
• 1.66:1
• 1.78:1 (16:9)
• 1.85:1
• 2.35:1 (Cinemascope)
To use aspect ratio’s in addition to these, the DreamScaler 4 provides the option to choose a custom aspect ratio
called User with a range of 1.01:1-3.00:1.
DreamScaler 4 Image Mapping
The situation when the Frame Aspect Ratio (FAR) is the same as the Active Aspect Ratio (AAR) is sometimes
called Full Frame. This situation is illustrated below.
The DreamScaler 4 maps the AAR to the Output Aspect Ratio (OAR) in the following three ways:
•When the AAR is greater than OAR, the DreamScaler 4 puts up Borders at the top and bottom as shown below:
• When the AAR is less than the OAR, the DreamScaler 4 puts up Borders on the left and right as shown below:
•When the AAR is equal to the OAR (Output Aspect Ratio), the DreamScaler 4 supplies no border as shown
below.

Panorama
The Panorama feature is a non-linear stretch that can be applied to a video source to fulfil a larger format. The
panorama stretches the picture with minimal perceptual distortion in the center of the screen. This mode can be
turned ‘On’ or ‘Off’ to a 4:3 picture to fulfill a 16:9 screen, or applied to a 16:9 picture to fulfill a 2.35:1 screen.
Zoom
The Zoom function zooms in on or magnifies the image on your display. The minimum zoom is 100%, (no zooming);
the maximum zoom is 150% (zoom magnification factor of 1.5X).
•Horizontal Zoom Control: Push the Enter button to show the current Zoom setting. Push the Up and Down
button to increase or decrease the zooming factor.
•Vertical Zoom Control: Push the Enter button to show the current Zoom setting. Push the Up and Down button to
increase or decrease the zooming factor.
Pan
The Pan function allows the image to be shifted up, down, left and right. Note that the Pan function can only be used
after the image has been zoomed to any value greater than 100%.
•Horizontal Pan Control: Push the Enter button to show the current Pan setting. Push the Up button to pan to the
right. Push the Down button to pan to the left.
•Vertical Pan Control: Push the Enter button to show the current Pan setting. Push the Up button to pan up. Push
the Down button to pan the image down.
Borders
The Borders function allows you to add horizontal and/or vertical borders around the image. These borders obscure
part of the input image. Certain input-to-output aspect ratios already result in left/right or top/bottom border being
added. This control allows the system-generated borders to be extended, or for borders to be added when none
exist. As the borders are adjusted (see below) theDreamScaler 4 temporarily increases the gray level of the borders
so that they are visible during the adjustment process. The level will return to normal after the adjustment has
ceased.
•Horizontal Border Control: Push the Up button to move the left and right borders towards the middle of the
image, increasing the border width and cutting off the sides of the input image. Push the Down button to move
the left and right borders away from the image and decreases their width. If there are system-generated left/right
borders already present (for example, when the input aspect ratio is 4:3 and the output aspect ratio is 16:9), the
border width cannot be decreased beyond the base width created by the aspect ratio conversion.
•Vertical Border Control: Push the Up button to move the top and bottom borders towards the middle of the
image, increasing the border height and cutting off the sides of the input image. Push the Down button to move
the top and bottom borders away from the image and decrease their height. If there are system-generated top/
bottom borders already present (for example, when the input aspect ratio is 16:9 and the output aspect ratio is
4:3), the border height cannot be decreased beyond the base height created by the aspect ratio conversion.
Borders are automatically added by the system when the Active Input Aspect Ratio is not the same as the Output
Aspect Ratio as explained earlier in this guide. However you can add more borders using the Borders menu.
Presets
You can specify the Input Aspect Ratio by using the Presets or Manually.
Using Presets
You can use Presets with either the OSD or the Remote Control Input Aspect Ratio button. Refer to the Preset sub-
menu in the Input AR menu for doing this with the OSD. The remote control operation is described below.
• 4:3 button selects 4:3 aspect ratio.
• 16:9 button selects 16:9 aspect ratio.
•Pan button selects 2.35 aspect ratio.
Pushing the Input Aspect Ratio button repeatedly selects Preset 1 through Preset 10 and User in sequence without
using the On-Screen Display (OSD).
The ten user-defined preset value selections (Preset 1 - 10) are stored in non-volatile memory and always available.
Each of these presets consists of the following:
•Frame Aspect Ratio
• Active Input Aspect Ratio
• Zoom parameter

4.0 MENU OPTIONS
R699761 - DreamScaler 4 User Manual 15
•Pan parameter
• Borders
The User preset selection is also stored in non-volatile memory. However the User selection is always updated after
you modify any pre-defined aspect ratio setting. In order to permanently keep a custom aspect ratio setting, you
must save it to one of the four preset selections.
Setting the Input Aspect Ratio Manually
You can set the following parameters manually:
•Frame Aspect Ratio
• Active Input Aspect Ratio
• Zoom factor
•Pan parameter
• Borders (horizontal and vertical)
The Active Input Aspect Ratio menu item lists the most common movie aspect ratios (1.33:1, 1.85:1 and 2.35:1).
You can also customize the Input Aspect Ratio using the Up and Down buttons.
Save User-defined presets as follows:
• Customize the aspect ratio manually (refer to Setting the Input Aspect Ratio Manually above).
• Select one of the presets from the ‘Save User To’ menu. Confirm the action by selecting Yes.
If you have not customized the aspect ratio, and the current aspect ratio settings are the same as a system defined
preset. In this case, the system will not allow you to save the preset setting.
4.3 Input Adjust Control
Push the Input Adjust button once to show the current input adjustment function.You can cycle through the available
functions by pushing this button repeatedly.
The available ‘input adjust’ functions are as follows:
• Deinterlacing Method
• PReP™
• Image Shift
•Overscan
• Color Space
• Input Level
• VCR mode
• HDMI Config
•Auto Priority
•Audio Input
•AV Lip Sync
Mosquito Noise Reduction
This option reduces the random noise that appears along the edges of compressed broadcasts. There are four
settings to this control: off, low, Medium, and High. The default setting for this control is ‘off’.
Deinterlacing
You can choose between seven different deinterlacing methods that better suits your need:
•Auto:
This setting is to be used with when the content may be a mix of film and video based content.
• Film Bias Mode:
Typically you only need to select the Frame Aspect Ratio and Active Input Aspect Ratio to get an acceptable
picture.
Be careful, because saving to a preset deletes the previous preset.

This mode is intended for use on content that is known to be film-based
• Video Mode:
This mode is intended for use on content that is known to be video-based.
•Forced 3:2
This mode is intended to be used with High-Quality film source like HD-DVD and Blue-Ray. This forced cadence
mode is definitely useful for watching a movie from start to finish but they are less useful for content with a lot of
bad edits, and also if you are going to skip chapters.
•Forced 2:2
Same as Forced 3:2 but applying a 2:2 filter.
• 2:2 Even:
This mode should be used when the user knows that the source is high-quality 2:2 pulldown (i.e. film-based
content played back in a country with a 50Hz video standard) and wants to avoid any loss of cadence lock while
watching that source. This mode weaves two adjacent fields together starting with an even field and combining it
with the following odd field. This will provide a higher quality overall signal than the ‘Auto’ or ‘Film Mode’ settings,
providing that the source really is 2:2 pulldown and does not have bad edits. Only one of the ‘2:2’ Deinterlacing
settings is correct for any given source and the correct mode can be chosen by simply trying both of them and
selecting the one which does not result in combing artifacts.
• 2:2 Odd:
This mode is very similar to ‘2:2 Even’ except that this weaves two adjacent fields together starting with an odd
field and combining it with the following even field.
• Game Mode 1:
This mode gives you minimal latency with edge-adaptive processing. The total amount of delay with source-
locked output mode set on the DreamScaler 4 is about half a frame of delay. Unlocked frame rates will increase
this delay.
• Game Mode 2:
This mode gives you minimal latency with both motion and edge-adaptive processing. The total amount of delay
with source-locked output mode set on the DreamScaler 4 is about one and a half frames of delay. Unlocked
frame rates will increase this delay.
PReP™
PReP™ stands for ”Progressive ReProcessing“. This is the first video processing method that significantly improves
progressive video signals and removes artifacts caused by inferior interlaced-to-progressive conversion. 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.
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.
Tu r ning on PReP™ video processing will improve images on high-resolution displays and give access to the
Precision Deinterlacing menu. PReP™ should be activated only with progressive video input known to be originally
interlaced.
Cadence Detect
This option can be turn on with progressive input signals. When the output framerate is not locked to the input
framerate, this processing features an advanced cadence detection that can detect a film-based content (originally
encoded at 24fps) within an upscaled signal.
Overscan
The Overscan function scales the input image proportionally in both vertical and horizontal dimensions by the user-
specified overscan factor. The purpose of Overscan is to remove unwanted image portions around the perimeter of
the image. The default overscan value is 0, which means 100% of the input image is shown. The maximum
overscan value is 20 which means the input image is scaled up by 120%.
Image Shift and Field Swap
These adjustments are available with HD-SDI and analog inputs. They allow a fine adjustment of the picture to the
selected output. These functions can be set independently for different input formats.
Color Space
The color space setting allows the user to specify what the input signal is on the RGBHV/Component and HDMI
inputs. The YPbPr setting only applies to the RGBHV/Component input. The YCbCr 4:2:2 and YCbCr 4:4:4 and Auto
settings only apply to the HDMI inputs. The options are:
• RGB

VCR Mode
VCR Mode decouples the output timing completely from the input timing to ensure a stable output from the
DreamScaler 4 for VCR playback especially during trick-play modes (play forward, play reverse, still/pause).
• On – Output timing is decoupled from the input timing regardless of Frame Rate settings.
• Off – Output timing is dependent on Frame Rate settings.
•Auto - Turns on VCR Mode if a VCR source is detected.
HDMI Config
HDCP mode
•Off: HDCP is disabled at the DreamScaler 4’s HDMI input. some sources turn off HDCP in this case and the
DreamScaler 4 drives a non-HDCP DVI display or an analog display.
• On: The DreamScaler 4 continuously looks for a HDCP source on its HDMI input.
Auto Aspect Ratio
• Off: The Aspect Ratio is determined by user.
• On: The DreamScaler 4 reads the video aspect ratio contained into the Info Frame and applies it if available.
Auto Colour Space
• Off: The Color space is determined by user.
• On: The DreamScaler 4 applies the Color Space specified into the Info Frame if available.
Auto Input Priority Selection
The Auto Input Priority Selection function assigns different priorities to the video input’s automatic active video
selection mode (AUTO in Input Select menu). First select the video input, then change the priority of that input.
1) Press the Down button. The first video input Video 1 is shown.

4.4 Input Picture Controls
Fine Detail
This control enhances the fine detail in pictures. Fine detail can be sharpened by adjusting the control into the
positive range, up to 100, it can be softened by adjusting this control into negative range down to -100. The
midrange setting is 0.
Edge Enhancement
This control enhances the sharpness of picture on the edges. To sharpen the edge change this setting into the
positive range up to 100, soften the edge setting a negative value up to -100. The midrange setting is 0.
Brightness
This control adjusts the brightness (black level) of the overall image output from the DreamScaler 4. If you turn it up
too high, it may make black look gray. In general, you should adjust this up until you see the black areas of your
display turn gray and then back it down just below that point. Default setting is 0 (midrange).
Contrast
Contrast adjusts the ratio between white and black signal levels and is effective as a gain control. The difference
between this and the Brightness control is that this adjusts the difference between the brightest and darkest part of
the image. Note that all displays have a maximum white level. Going beyond this level only “clips” the upper gray
levels and you will lose color resolution at the brighter levels. Adjust this control up until you see the brighter levels
of the image begin to wash out. At this point, back it down just below that point. The default setting is 0 (midrange).
Saturation
The DreamScaler 4 allows you to control the saturation of the image independent of the display. Saturation is the
same as the “Color” control on most TVs and controls the richness of the color in the image. The default setting is 0
(midrange).
Hue
As with Saturation, hue can also be controlled independent of the display. Hue is the same as the “Tint” control
found on most TVs and controls how colors are displayed in the image. The Hue control is not available for
Component or PAL/SECAM inputs. The default setting is 0 (midrange).
Y/C Delay
Sometimes there is a lag between the Luminance (Y) and the Chrominance (Pb/Pr or Cb/Cr) of the video signal.
This causes a color “smearing” because the color component of the image is not lining up properly to the black and
white luminance component of the image. The DreamScaler 4 can compensate for these errors in the source signal
by shifting the phase of the Y with respect to the C, forward or backward to align them properly.
Use the Down and Up buttons to adjust the phase and observe the effects on your display to obtain the optimal
setting. The default is 0.
Note:
The total audio delay cannot be less than zero, that is, the DreamScaler 4 cannot have negative audio delay. If you
choose to decrease the automatic delay setting by a certain amount, this value could be changed by the
DreamScaler 4 in situations where the DreamScaler 4’s calculated delay plus the specified additional delay results
in a value less than zero.

Chroma Filter (Auto CUE-C)
This feature removes chroma upsampling errors (CUE) found in video sources which have been MPEG encoded
and then improperly decoded.
• Off - No chroma filtering. Use this setting if the source does not have a CUE problem.
• On - Chroma filtering is always on. Use this setting if the source is known to have a CUE problem.
•Auto - Automatic chroma error detection and correction. Use this setting when you don’t know if a source has a
CUE problem. Also use this setting for all digital sources which use MPEG2 decoders (DVD players, digital
satellite receivers, and so on.) as it will also detect and correct chroma errors created by all sources of this type
when the source is encoded as interlaced (also sometimes called Interlaced Chroma Problem, or ICP).
