INTRODUCTION
1.1.
General Introduction
HQView-4xx is a very flexible image scaler developed specifically for driving large screen displays and
multiple screen applications from video or graphics sources.
HQView-4xx features state of the art digital image processor which provides market leading HD & SD
per-pixel multiple Iow-angle motion-adaptive de-interlacing and automatic film pull-down correction for
3:2 and 2:2, significantly outperforming the capabilities of benchmark competitor products. HQView-4xx
features excellent image processing algorithms for the very best scaling, film and video noise reduction
and MPEG artefact reduction.
HQView-4xx uses a very flexible high performance video input front end including true component video
support in analogue YPbPr and RGBS formats and HDSDI/SDI digital formats as well as composite
(CVBS) and YC/S-Video inputs. A very high performance video decoder is utilised with 4x oversampling
and 3D Y/C separation for outstanding video image clarity. HDMI and DVI video with HDCP encryption
is also supported, as are computer graphics inputs in SVGA analogue and HDMI/DVI digital formats.
The output format can be set to I/O Lock mode where it locks the output frame rate to the input frame
rate dynamically without frame rate conversion so as to reduce system latency, or it can be set to a fixed
output frame rate for driving basic screens which are not 50Hz-compatible. A Low latency mode with
non-motion adaptive reduced processing is available to further reduce latency.
Outputs are available in VGA analogue and DVI digital formats which are useable simultaneously so
that one output can drive the screen while the other runs a local monitor.
Note: If an HDCP encrypted signal is connected to the HDMI or DVI input, the DVI output signal will be
HDCP encrypted and the output that cannot be encrypted (VGA analogue output) will be disabled.
Interlaced outputs are supported, there is a vertical temporal filter facility which greatly reduces interlace
flicker.
HQView-4xx supports Pan, Tilt and Zoom to select a ‘region of interest’ portion of the input image, fill
the screen and pan/tilt within it.
HQView-4xx can be operated with different firmware. At time of issuing this document four firmware
versions are available. Each firmware version provides different feature sets controlled through the
menu. Special emphasize is given in the discussion of the OSD (On Screen Display) menu system in
the corresponding chapters.
In the basic configuration HQView-400S used for single display installations Picture in Picture
functionality is provided.
The next version is the HQView-410 for multi screen or multi projector installations such as geometry
correction, Auto Zoom and Edge Blend.
Edge Blend electronically reduces the brightness level of certain image regions to seamlessly match the
brightness of overlapping areas. Auto Zoom automatically crops and zooms the input video image to
display a section of the total image on the corresponding projector or screen. Embedded warp allows
adjustment of the image in a projection scenario to match a rotated, tilted or curved screen. For 9:16
portrait mode signage special predefined portrait modes are available to rotate and stretch a video
image to fill a +/-90° rotated display panel.
HQView-420 adds free form warp capability for non-flat screens in single or multi projector installation.
Warp maps created with the PC tool “Warp Generator” can be uploaded into HQView-420 and
processed accordingly.
System control is via an OSD controlled by keys on the front panel or through the inbuilt TCP/IP web
server.
Additionally a free API manual is published on our website at the link given below to allow the use of the
LAN or RS232 remote control ports.

Introduction
The front panel has keys for OSD menu navigation, input channel selection and often used functions.
OSD navigation is through two direction keys and a Menu/Enter key.
1 –Standby key: When applying power to the unit it starts up. This is indicated by the green On LED
flashing. Once the unit is operational, the On LED is permanently on. By pressing the Standby Key, the
unit is put into standby mode. This is indicated by the red Standby LED being permanently on. The red
Keylocked LED indicates a keypad locking condition issued through the OSD menu. If a key on the front
panel is now pressed an OSD message comes up and displays the multiple key press to be applied to
unlock the front panel keys.
2 –Input channel selection keys: All input channels can be directly selected. The active channel is
indicated by the red LED above the corresponding channel key being on.
3 –PiP or AutoZoom key: A HQView-400 has a key to directly activate the PiP mode. The green LED is
switched on when in PiP mode. HQView-410 and 420 have a key to directly activate the AutoZoom
mode instead. The green LED is switched on when in AutoZoom mode.
4 –OSD navigational keys: With the Menu key the OSD menu is activated.
The up/down keys are used for OSD menu navigation. To exit the OSD menu or any submenu press
the up and down key simultaneously or navigate to the Exit item and press the menu key. To access a
submenu navigate to it and press the menu key. To apply a change go to the menu item, press the
menu key and make a parameter change with the up/down key. Confirm the change by pressing the
Menu key. This will also bring you back to the submenu.

3.3.
Main Menu
The main menu lists the input channel select item, 6 sub menus, and a menu item for automatic setup
of VGA modes. The 6 sub menus are Output, Colour, Geometry, PiP (HQView-400S) or Multiple Unit
(HQView-410 and 420), Enhancement and System.
On each menu page an Exit menu item is available to leave the menu or submenu. Alternatively press
up and down buttons together, this will also exit that level of menu.
Some adjustments are not applicable to all signal types or operating modes, in which case those non-
applicable functions will be greyed out (ghosted).
All menus have a top status line and a bottom firmware revision information line.
In the status line the currently selected input channel is indicated and the detected mode is identified.
The bottom line shows the revision number of the boot-loader behind BL, the revision number of the
firmware behind FW and whether it is a 400S, 410, 420 type HQView unit.
To set up your HQView-4xx it is recommended that you follow this procedure:
Choose the correct output mode and parameters to suit your screen or projector.
Select the correct input signal.
Set the input levels and features appropriately to optimize the appearance of your image.
Set any other parameters to suit your application.
Note: The processor is designed to have separate memories for all the settings in each section. All Input
parameters are specific to your chosen input channel and input signal type, they are not global to the
unit. If you change the settings in for example the composite video channel you will not affect the
settings you may have made in for example the DVI channel.
All Output parameters only affect the output, they do not affect any of the inputs but please note that the
appearance on the screen because it is the output these adjustments will appear to be global.
3.4.
Input
The list of available inputs can be scrolled through using the Up and Down keys. The new input is not
selected until the Menu key is pressed.
The list of inputs are: CVBS 1, CVBS 2, S-Video, Component, VGA, HD-SDI, HDMI and Test Pattern.
Test patterns can be generated by HQView-4xx without needing an input connected. When Test Pattern
is selected as the input, the required test pattern can be chosen with the menu navigation up/down keys
when the OSD menu is off.

3.5. Output
This menu contains adjustments associated with setting up outputs from the unit. The items are
organized in two sub menus, Display Type and Gamma/Colour/Crush. Use the up and down keys to
scroll to the required item and press the Menu key.
3.5.1. Display Type
Settings: Projector, LCD/Plasma
Select Projector if you need the blend and warp function.
Set to LCD/Plasma if you do not need these functions to be shown in the menu system.
3.5.2. Output Mode
Settings: 640x480, 800x600, 1024x768, 1280x768, 1280x800, 1280x1024, 1360x768, 1366x768,
1400x1050, 1440x900, 1600x1200, 1680x1050, 1920x1200, 480i, 576i, 480p, 576p, 1080i, 720p, 1080p
Set up the desired output resolution with output mode. The output mode setting should match the native
resolution of the imaging device to avoid double scaling.
The default output resolution as set by the factory or after a user issued factory reset is 640x480.
Pressing the Menu/Contrast up/Contrast down key combination will switch the output resolution from
640x480 to 480i which some monitors may prefer.
If a DVI or VGA monitor has issues to display this 480i mode, by pressing the key combination again the
640x480 output mode is set-up which all DVI and VGA monitors should be capable to display.
3.5.3. Location
Settings: Front Tabletop, Front Ceiling, Rear Tabletop, Rear Ceiling
The image can be flipped to accommodate different projection scenarios as well as screens mounted
upside down.
3.5.4. Frame Rate
Settings: 60 Hz, 50 Hz, 48 Hz, 24 Hz, Auto
In auto mode the output frame rate follows the input frame rate as configured in the Output Config
menu. Signals with 24Hz, 25Hz, 48Hz, 50Hz input modes get special treatment, modes with other
refresh rates are displayed at 60Hz.
24Hz input modes will be output at 24Hz if the output resolution is set to either 720p or 1080p and the
Frame Rate setting in the Output Config menu includes 24Hz, otherwise it is displayed at twice the rate
if the Frame Rate setting in the Output Config menu includes 48Hz. Otherwise a 24Hz input mode is
displayed at 60Hz.
48Hz input modes will be output at 48Hz if the Frame Rate setting in the Output Config menu includes
48Hz. Otherwise it is displayed at 50Hz.
A 25Hz input mode is output at twice the frame rate 50Hz.
An exception to the 24/25Hz input mode treatment is if the output resolution is set to 480i or 480p. 480i
and 480p are always run at 60Hz output rate.
50Hz input modes are displayed at 50Hz output rate.
The output frame rate can also manually set to 24Hz, 48Hz, 50Hz or 60Hz if possible, i.e. such output
modes are available.
Only 720p and 1080p output modes are available with 24Hz refresh rate.

©Calibre UK Limited Issue 2.30 15th March 2013, W: www.calibreuk.com
T:[phone] F: [phone] E: [email protected] 15
480i and 480p output modes are only available at 60Hz refresh rate.
For all other modes 48Hz, 50Hz and 60Hz refresh rate is available.
3.5.5. I/O Lock
Settings: On, Off
If I/O Lock is switched off the output is run with a fixed refresh rate determined by the frame rate setting.
This setting will result in the output vertical refresh rate deviating from the input refresh rate, even if both
are nominally at the same rate. This causes occasional frame dropping or repeat.
If I/O Lock is set to Source the output refresh rate is following the input video refresh rate if possible.
Locking is achieved by modulating the output clock and works if input and output refresh rate are
nominally at the same rate, e.g. when frame rate is set to 60Hz and the video input is also 60Hz. If e.g.
the video input rate is 50 Hz and the Frame rate is set to 60Hz, the output will enter free run mode.
3.5.6. Native Colour Temp
Settings: 5500, 6500, 7500, 9300, 10000
Native Colour Temp allows the user to select from pre-configured color temperatures to match the
display. If both Native Colour Temp set here in the Output menu and Colour Temp set in the Colour
menu are set to the same value, no conversion is performed.
3.5.7. Output Gamma
Settings: 1.0 to 3.0 in steps of 0.1
Output gamma allows to re-gamma video signals with pre-configured gamma values to match the
display. Input gamma and output gamma both default to 2.2. If they are both set to the same value,
there is no effect on the image.
Note: If e.g. an adjustment to reduce the level of red in the image is required, select a higher number for
the (input) Colour Temp in the Colour menu, or a lower number for the Native Colour Temp in the
Output menu.
3.5.8. Output Config
This Menu provides items to configure the output ports.
Sync Mode
The VGA output port can be operated with separate syncs, composite syncs and Sync-On-Green.
Internally, the display interface processes data at a full ten bits per colour.
Optimize for Display
Settings: DVI forced, Optimized, DVI/HDMI
Internally, the display interface processes data at a full ten bits per colour. A resolution of ten bits per
colour is provided for the VGA output. The colour depth on the DVI-D output is determined by the
supported standard of the attached monitor or device when set to DVI/HDMI.
For DVI 1.0 and HDMI 1.1/1.2 devices it is 24 bit, for HDMI 1.3 compliant devices it is up to 36 bit.
DVI forced will output with 24 bit colour depth irrespective of the supported standard of the attached
monitor.
When the Optimized setting is enabled the output resolution is automatically set to the native screen
resolution of the attached display. The colour depth is determined in the same way as when set to
DVI/HDMI.

DVI Colour Space and DVI Range
The colour space of the DVI output port can be set to RGB or YPbPr, the range can be set to Expand,
Normal, Compress and Auto.
A limited video range is only using the following greyscale for video information - 8 Bit System: 0x01 ..
0xFE, 10 Bit System: 0x004 .. 0x03FB.
Auto makes the best choice for the range for the DVI and 3G-SDI output. If the HDMI/DVI output does
not behave as expected, e.g. because the HDMI display is not evaluating AVInfoFrames properly, the
range can be changed manually.
Frame Rates
Settings: 60/50 Hz, 60/50/24 Hz, 60/50/48, 60/50/24/48
Limits the possible output frame rates that can be selected. It is primarily to be able to limit the choices
available for the Auto refresh rate configuration discussed in paragraph 3.5.3.
