2. INSTALLATION
The 7712HDC-S comes with a companion rear plate that occupies two slots in the frame and has 7 BNC
connectors, and one female DB9 connector. The 7712HDC-SN-EAES4 comes with a companion rear
plate that occupies two slots in the frame and has 9 BNC connectors, and one female DB9 connector. For
information on mounting the rear plate and inserting the module into the frame see the 7700FR chapter
section 3.
Figure 2: 7712HDC Rear Panels
2.1. VIDEO CONNECTIONS
HD INPUT Input BNC connector for 10-bit serial digital video signals compatible with the SMPTE 292M
standard. The 7712HDC can be set to automatically detect the standard or set to a specific
video standard using the on screen menu. See Table 2 for a list of the video standards
supported.
SDI OUTPUT These two BNC connectors are used to output the downconverted input video as serial
component video, compatible with the SMPTE 259M standard.

7700 MultiFrame Manual
7712HDC HD Broadcast Quality Down Converter
7712HDC-4 Revision 1.2
MON OUTPUT These two BNC connectors are used to output the downconverted input video as
monitor grade analog composite video. They can be used to conveniently view the on screen
menu and status display on a low cost analog monitor.
ANALOG OUTPUT (7712HDC-SN-EAES4 only) These two BNC connectors are used to output the
downconverted input video as broadcast quality analog composite video.
2.2. GENLOCK REFERENCE
For proper synchronization of the output video, the downconverter must be locked to a genlock signal of
the output video format. In addition, the input video must be clock-locked to the genlock signal.
GENLOCK These two BNCs form a loop through for connecting an analog genlock reference. The
genlock signal may be NTSC or PAL colour black (the same as the output video format),
and is auto-detected by the module. Jumper J9 on the APB3FMTCON submodule selects
whether the reference input is terminated to 75 ohms or high impedance (default). (See
section 7.3). The output video can be timed with respect to the genlock video using the H
Phase Offset and V Phase Offset menu items. (See section 6.3.3) When no Genlock is
provided, the output video is timed with respect to the input video.
2.3. AUXILLIARY I/O
On the 7712HDC-S a 9 pin D connector labeled AUX I/O contains 2 GPI inputs, a 6 Hz input and 1 GPO
output. On the 7712HDC-SN-EAES4 a 9 pin D connector labeled AUDIO AND AUX I/O contains 2 GPI
inputs, a 6 Hz input, 1 GPO output and 4 unbalanced AES outputs. The connector pinout is shown in
Table 1.

Table 1: 9 Pin D Connector Pin Definitions
2.3.1. AES Audio Connections (7712HDC-SN-EAES4 version)
Four unbalanced AES outputs are provided on the 9 pin D connector. These outputs are for unbalanced
AES signals conforming to SMPTE 276M. Two groups of embedded audio from the HD input are extracted
and re-embedded on the output video. The transferred audio is also output as four AES channels.

7712HDC HD Broadcast Quality Down Converter
Revision 1.2 7712HDC-5
2.3.2. General Purpose Inputs and Outputs
3 pins on the 9 pin D connector are used for three general purpose inputs (GPIs). One of these inputs is
used for a 6 Hz input to the downconverter. The GPI1 and GPI2 inputs are used to select user presets 1
and 2 respectively. The GPIs are active low with an internal pull up (3.6k ohm) resistor to +5V or +12V.
The user can activate GPIs simply by connecting the GPI input pins to Ground. This can be done with a
button, switch, relay or an open collector transistor. See section 7.4 for information on selecting the pull-up
voltage. Figure 3 shows the input circuit for the general purpose inputs.

5. CARD EDGE CONTROLS
The 7712HDC series modules are equipped with an 8 position DIP switch to allow the user to select
various functions. All positions are assigned sequentially such that the DIP switch 1 is located at the top
of the DIP switch (farthest from the card ejector). Table 4 gives an overview of the DIP switch functions.
Sections 5.1 to 5.2 describe the assigned DIP switch functions. The On position is down, or closest to the
printed circuit board. There is also a toggle switch and pushbutton which are used to navigate the on
screen menu. (See section 6)

6. ON SCREEN MENUS
6.1. NAGIVATING THE ON SCREEN MENU SYSTEM
A toggle switch and pushbutton allow card edge navigation of a set of on-screen menus used to configure
the card. To enter the on-screen menu system, press the pushbutton once. This will bring you to the
main setup menu where you can use the toggle switch to move up and down the list of available sub
menus. An arrow (!) moves up and down the left hand side of the menu items to indicate which item you
are currently choosing. Once the arrow is on the desired item, press the pushbutton to select the next
menu level.
On all menus, there are two extra selectable items: Back and Exit. Selecting Back will take you to the
previous menu (the one that was used to get into the current menu) while Exit will return the display to its
normal operating mode. On the main menu, BACK and EXIT will both take you to the normal operating
mode.
Once in a sub menu, there may be another menu layer, or there may be a list of parameters to adjust. If
there is another set of menu choices, use the toggle switch to select the desired menu item and press the
pushbutton.
To adjust any parameter, use the toggle switch to move up or down to the desired parameter and press
the pushbutton. The arrow will move to the right hand side of the line (") indicating that you can now
adjust the parameter. Using the toggle switch, adjust the parameter to its desired value. If the parameter

Revision 1.2 7712HDC-11
is a numerical value, the number will increase if you lift the toggle switch and decrease if you push down
on the toggle switch.
When you have stopped at the desired value, depress the pushbutton. This will update the parameter to
the selected value and move the arrow back to the left side of the parameter list (!). Continue selecting
and adjusting other parameters or use the BACK or EXIT commands.
6.2. ON SCREEN DISPLAY – MAIN MENU
The OSD menu is arranged in a layered structure that groups similar configuration items together. The
following section gives a brief description of the first level of menus that appear when you enter the OSD
screens. Selecting one of these items will take you to the next menu level. Sections 6.3 to 6.10 provide
detailed descriptions of each of the sub menus. The tables in sections 6.3 to 6.10 are arranged in an
indented structure to indicate the path taken to reach the control. Menu items or parameters that are
underlined indicate the factory default values.

With this control, you can set the input and output video
standards.
Note: When set to Auto, the module can not distinguish between
1080i/59.94 and 1080p/29.97sF, so it will be treated as
1080i/59.94. Similarly 1080p/25sF will be treated as 1080i/50.
Note: 1080p/23.98sF not supported on S version.
6.3.2. 3:2 Pulldown Processing
When using a 1080i/59.94 input video feed containing 3:2 pulldown, the 7712HDC must be operated in
Field Mode in order to minimize motion artifacts. In Field mode each field of the incoming image will be
downconverted to one field of output image, so there will be no pulldown related de-interlacing artifacts on
film originated material with 3:2 pulldown, or video originated material acquired at a nominal 24 frames per
second.
When using a 720p/59.94 input video feed the 7712HDC will operates in Frame Mode where each frame
of the incoming image will be downconverted to one field of output image, so there will be no pulldown
related artifacts on film originated material with 3:2 pulldown, or video originated material acquired at a
nominal 24 frames per second.

7712HDC HD Broadcast Quality Down Converter
Revision 1.2 7712HDC-13
When using a 1080p/23.98sF input video feed the 7712HDC-SN-EAES4 operates in Frame Mode where
each segment of the incoming image is combined back to a progressive frame before down conversion.
After down conversion, extra fields are inserted to create a 3:2 pulldown at the output. The Pulldown
Reference menu is used to determine the cadence of the 3:2 output.

On 1080p/23.98sF video inputs the Pulldown Reference menu is used to
identify the input frame that will become an A frame at the output. This
frame is called the A frame candidate (see Figure 5). The output of the A
frame candidate frame will delayed by 2 frames, will consist of two video
fields and will normally be in time with the genlock input. (See sections
6.3.3 and 6.3.3.3 for information on phasing of the output video with respect
to the genlock.) Additionally, an offset can be added to the A Frame
reference using the A Frame Offset control to accommodate situations
where the A frames are not in time with the A Frame reference. (See
section 6.3.2.2)
When you select Auto the 7712HDC-SN-EAES4 will auto detect the
pulldown reference according to the following priority:
•6 Hz pulse if present
•RP188 ancillary timecode if present
•Free Run pulldown if neither 6 Hz pulse or RP188 is present
Select RP 188 when the embedded ancillary timecode present on the input
video is used to determine the pulldown. The input frames with time code
frame numbers divisible evenly by 4 will normally identify the input A frame
candidates.
Select 6 Hz Input when a 6 Hz pulse connected to pin 6 of the AUXILIARY
I/O connector is used to determine the pulldown. The 6 Hz pulse should be
a 1/30th second wide TTL level active high pulse occurring 6 times per
second and must be coincident with the start of an input frame. The 6 Hz
pulse with normally identify the A frame candidates.
Select Free Run when you want a continuous 3:2 pulldown on the output
but do not care if it matches specific frames of the input video.
