INTRODUCTION

Congratulations on your purchase of the 3GSDI to HDMI 1.3 Scaler. Your
complete satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes
with hard-working solutions that are easy to implement and simple to operate.

The Gefen 3GSDI to HDMI 1.3 Scaler

The Gefen 3GSDI to HDMI 1.3 Scaler will take any SDI, HD-SDI, or 3G-SDI
video signal and convert it to HDMI 1.3 scaled to the output resolution of your
display device. The SDI input signal will simply be converted to an HDMI signal.
A user-friendly On-Screen Display will allow the user to select features such as
Deep Color conversion and colorspace. A built-in 720p (60Hz) test pattern is also
available without connecting an SDI source, useful for checking the HDMI video
output. An SDI loop out and a S/PDIF digital audio output are also provided for
monitoring the input SDI source and/or distributing the SDI audio to an external
digital amplifi cation device.

How It Works

The 3GSDI to HDMI Scaler converts an SDI source signal (SD/HD/3G-SDI) to
an HDMI 1.3-compliant A/V signal which is then scaled to optimally fi t the output/
display device at resolutions of up to 2048x1080p24.

The SDI source device is connected to the SDI input. An HDMI-compliant output
device is connected to the HDMI A/V output connector. The included power
supply is connected and plugged into an available wall socket. The input signals
are now converted to the proper output format and scaled to your choice of
resolutions on the output device.

The Gefen 3GSDI to HDMI 1.3 Scaler supports Deep Color at 10 bits in the 4:4:4
confi gurations. Deep Color can be set to Automatic or Forced to 8 bits. The 8-bit option
disables the transmission of Deep Color packets. The automatic option will transmit in
deep color whenever possible, according to the EDID information of the monitor. To be able
to output HDMI 1.3 in Deep Color at 10 bits you must be using YCbCr 4:4:4 or the RGB
4:4:4 output color space (YCbCr 4:2:2 does not support Deep Color). Some monitors may
support Deep Color in only one of the possible link confi gurations (RGB & YCbCr 4:4:4),
while others may not support Deep Color at all. Verify the display device’s user manual for

CONNECTING AND OPERATING THE 3GSDI TO HDMI 1.3 SCALER

SDI Input Format

When the Scaler sees a valid SD/HD/3G-SDI source as input, the format is displayed at the
bottom of the OSD and checked in the menu choices. “Auto detect” appears if no valid input
is found. In such cases, the Scaler can be set to use a specifi c format. To do so, set the link
confi guration fi rst (see below) to avoid mistakes such as confusing dual link resolution with
single link (as in 1080p). With SDI single link, the input source can be set to SDI input 1 or
SDI input 2. Therefore, exert caution when setting the input format.

Figure 16 - Input Format

SDI Input Link Confi guration

The Link Confi guration must be set to correctly recognize the type of input signal. Many SDI
dual-link signals can be interpreted as single link. Examples of valid SDI link confi guration
menu choices in the OSD are shown below in Figure 17. The SDI source MUST be
connected fi rst or the Scaler will not allow link confi guration. The selected link confi guration
appears marked in the list of choices (see Figure 17). Incompatible choices will cause the
Single Link mark to remain selected without an operation being performed.

Figure 17 - Link Confi guration

When processing a dual-line interface with two input signals at 1080i each, you must
select the Dual Link 1080p/576p/480p option, otherwise the incoming input signal will
be interpreted as a single-link 1080-line interlaced signal. The same applies to 576p and
480p, which are seen as 576i and 480i. Many other problems can occur from a bad link
confi guration. Every time the input link type changes, you should re-confi gure it in the OSD.

CONNECTING AND OPERATING THE 3GSDI TO HDMI 1.3 SCALER

Clean Aperture

The clean aperture size and position can be confi gured. You can set the percentage (as
a function of the production aperture) of the signal that is active. By default the horizontal
and vertical size is set to 100% and centered at 50, 50 as the horizontal and vertical
position. Note that if no video signal input is detected this menu is disabled.

Figure 18 - Clean Aperture

Film Mode

The fi lm mode feature can be enabled or disabled. It produces a progressively scanned
output image from an interlaced scanned input image accounting for fi lm mode
cadence (e.g. 3:2 / 2:2 pull-down) including bad edit detection, static / freeze frame,
multi-directional motion and inter-fi eld motion.

IR Remote Channel

The Scaler’s IR remote control transmits IR codes on a single infrared channel. A total
of four (4) channels are available for use by the Scaler and its IR Remote. If the remote
control and/or Scaler becomes inoperable due to a confl ict with another IR device in the
nearby vicinity, the IR channel may be changed. The IR channel must be changed both
within the Scaler OSD (see below, Figure 21) and inside the back panel of the IR remote
next to the battery compartment (see page 8).

CONNECTING AND OPERATING THE 3GSDI TO HDMI 1.3 SCALER

Picture Adjustment/Enhancement Functions

The Scaler’s operating functions can be adjusted to produce the best output picture
possible with the connected equipment. The following submenus in the OSD will outline
these capabilities:

Figure 22 - Picture Adjustments

Color Brightness & Contrast Adjustments

The brightness and contrast can be adjusted for each primary color (red, green
and blue). The default is 50 with a range of 0 to 100. Increasing or decreasing the
brightness of all colors will make the whole picture brighter and/or increase the contrast
in general.

The SDI black level is defi ned as the offset between the input and output color levels. A
value of zero means that no change occurred between input and output on the Scaler,
thus ensuring that the super black was preserved from SDI to HDMI.

CONNECTING AND OPERATING THE 3GSDI TO HDMI 1.3 SCALER

Gamma Correction

Gamma correction and the gamma coeffi cient may be adjusted in this screen of the
OSD menu system.

Figure 24 - Gamma Correction

Two predefi ned tables are available: Default and sRGB. The user can also defi ne a custom
User Table by using commands sent over the USB port via the downloaded software from
Gefen (see Appendix B, p. 27). When the Custom User Table is selected, the gamma
coeffi cient is used to calculate a new Gamma Look up table. The gamma coeffi cient can
be adjusted from 0.3 to 3.0 (by default the gamma coeffi cient is 1.0). These functions are
covered in detail starting on page 27.

CONNECTING AND OPERATING THE 3GSDI TO HDMI 1.3 SCALER

Size & Position of the Output Picture

The size and position of the HDMI output picture can be changed. By default, the horizontal
and vertical dimensions fully match the output dimensions. For example, an output format
of 720p will have a horizontal size of 1280 and a vertical size of 720 (see Figure 30 below).
These values may be decreased to reduce the size of the output picture, after which it may
be moved horizontally or vertically. Note: A picture whose size is the same as the output
format cannot be moved horizontally or vertically.

Figure 30 - Picture Size and Position

Aspect Ratio

This menu allows the HDMI output signal’s aspect ratio to be modifi ed.

Figure 31 - Aspect Ratio

Several Aspect Ratio Modes are available. In Full Screen Mode, the Scaler transforms
the input signal to the selected resolution on the output device. For example, if the Scaler
receives an SDI 480i 4:3 signal and the output is set to HD 720p 16:9, the output signal will
have an aspect ratio of 16:9.

In Letter/Pillar Box Mode, the Scaler will keep aspect ratio received from the source. For
example, if you input 480i at 4:3 and output 720p at 16:9 HD format, the picture will occupy
only the center of the screen and black bars will be placed on each side. This option has
no effect if the input and the target aspect ratios are identical. The panoramic zoom feature
can be used on non-linear inputs to make then fi t on the output device.

CONNECTING AND OPERATING THE 3GSDI TO HDMI 1.3 SCALER

Extracting a Subset of the Source Signal

The Extract command takes a subset (cropping) of the SD/HD/3G-SDI source picture and
replicates that portion only to the HDMI output device. The extraction size (crop size) can
be selected in the OSD menu. By default 100% of the picture is extracted.

Figure 33 - Through (No Scaling)

Through Mode

The Through mode does not resize or scale the picture. For example, a 1280x720p HD-SDI
input signal sent to an HDMI output device with a greater native resolution than 1280x720
will have horizontal and vertical black bars on the outer edges of the centered image being
received from the Scaler. Horizontal and vertical size can be selected from the OSD menus
and the output format can be reduced from 100% (1280x720p) down to as little as 1%.
The position where the selection window is defi ned can be modifi ed with the horizontal and
vertical position slider controls (see Figure 33 below). The default screen position is 50 for
both horizontal and vertical positions.

TROUBLESHOOTING

Troubleshooting Tips

The power LED is continuously blinking.

• First, disconnect all input and output A/V devices from the Scaler, then reset it by
removing the power for several seconds. If the problem persists, try performing a
software upgrade (see Appendix A, page 27).

• Note that the power LED blinks when it receives an infrared signal. This is normal
behavior that happens when a button is pressed on the IR Remote.

The power LED blinks and the menu is changed when an IR remote from another product
in the A/V system is used.

• When the IR channel used by the Scaler is used by another piece of equipment
nearby, malfunctions can occur. The Scaler’s IR channel should be changed
within the OSD menu. One of up to four choices can be made. It will also be
necessary to change the IR channel on the Remote by manipulating the DIP
switches inside the battery compartment (see page 9).

The Scaler outputs a blank screen when there is a valid SDI source connected.

• Is the current input format supported by the Scaler? See the supported input formats
table. Try to push the source button to change the SDI input selected.

• Make sure that the cables are connected correctly for the format type being used. If
using a Dual-Link SDI source, make sure that the link confi guration is set properly
within the OSD menu system. You can also enable the Auto-Detect function.

The OSD cannot be displayed; the screen is black.

• Push the MENU button on the remote. The Scaler power LED should blink; if it
does not, then it is likely that the Scaler and Remote are not communicating. See
troubleshooting for the Remote.

• Try to reset the Scaler by removing power and applying it again. The output format
might not be supported by the monitor. Push the remote output button and verify that
the power LED blinks while you push the button. Wait 30 seconds. If nothing happens,
push the MENU button and wait for the OSD (repeat if necessary). If none of these
procedures produce results, restore the default factory confi guration by pushing the
following sequence of keys on the IR remote: LEFT RIGHT and OK.

The output color and picture are not correct.

• Have you connected a valid SDI input source and have you selected the correct link
confi guration in the OSD Menu? Connect the SDI input fi rst, then enter the OSD and
select the appropriate link type.

The input format is not detected correctly.

• Verify all connections fi rst. If using a dual-link input source, make sure that the two
SDI input cables 1 & 2 are connected properly to the fi rst and second SDI input ports
on the rear of the Scaler. Also, verify that the SDI input is connected on an SDI signal
input jack and not a loop out (monitoring connector) and that the Scaler is aware of the
confi guration type (link confi guration menu) Also try to reset the Scaler and the SDI
input source.

TROUBLESHOOTING

Troubleshooting Tips, Continued

Deep color is not working.

• Does the display device on the HDMI output support HDMI 1.3 and Deep Color?

• Make sure the output link confi guration is not set to YCbCr 4:2:2, since YCbCr 4:2:2
does not support Deep Color. In the OSD, set the link confi guration in the output menu
to RGB 4:4:4. Also try YCbCr 4:4:4.

The Scaler is not responding to the IR remote control commands.

• Does the LED on the IR remote blink when you push on any one of the buttons? If not,
try changing the IR remote’s batteries.

• If the power LED blinks when pushing the IR Remote’s MENU button near the Scaler
but not farther away from the Scaler, the Scaler’s IR signal is probably blocked. Place
the Scaler in another location where the Remote’s IR signal will reach it.

• The IR remote and the Scaler must be on the same IR channel. The Scaler’s IR
channel is set through the OSD menu. The infrared remote’s IR channel is selected
by adjusting the 2 DIP switches near the batteries (see page 9). Try all channels if
necessary, especially if two scalers are being used in the same room.

A menu item is inaccessible (disabled).

• The availability of OSD menu items is evaluated in real time by the Scaler. If the
Scaler cannot activate the desired feature, the corresponding menu item will be
disabled to prevent harm to the Scaler and/or connected equipment.

The Horizontal or Vertical screen position cannot be changed (from the OSD).

• For screen positions to change, picture size must be reduced so that it fi ts within the
boundaries of the display device. Use the OSD to reduce the picture, then try again.

The picture has bars or stripes on the edges.

• Verify that the Aspect Ratio confi guration option is set to Full Screen. If so, and the
problem continues, it is possible that the distortions are part of the source signal.

When these remedies do not solve the problem being experienced, please
update the Scaler’s software to the latest release and restart operation.
Please see page 27 for details on the software update procedure.
