7713HDC Downconverter & Distribution Amplifier
1. OVERVIEW
The 7713HDC is a reclocking high definition serial digital video distribution amplifier and a high quality
downconverter for 1.5 Gb/s HDTV signals. It can also function as a monitoring distribution amplifier for
standard definition 270 Mb/s signals. The 7713HDC provides 4 reclocked DA outputs and 3
downconverted SDI or composite analog NTSC/PAL outputs (selectable). The 7713HDC accepts all the
popular international SMPTE 292M video formats. When the 7713HDC down converts 1080p/23.98sF
input video to 525i/59.94 with a 3:2 pulldown, the 3:2 pulldown cadence can be free running, locked to
embedded RP188 time code or an external 6Hz input.
The 7713HDC has color space conversion from ITU rec. 709 to ITU rec. 601, and will provide various
down converted formats such as 16:9 letterbox, 14:9 letterbox, 13:9 letterbox, 4:3 center crop, and 4:3
anamorphic squeeze. Full 10 bit processing is provided throughout the signal path to achieve excellent
downconversion quality with detail enhancement and gamma correction. The 7713HDC has the ability to
adjust video parameters such as brightness, hue and saturation. The 7713HDC also de-embeds two
groups of audio and re-embeds the audio on the SDI output in time with the video. It can also reassign
audio channels within the groups. All parameters may be controlled by use of the on screen display menu
or through VistaLINK™ PRO.
The 7713HDC provides card edge LEDs to indicate signal present and audio groups present. The
7713HDC occupies one card slot in the 3 RU frame, which will hold up to 15 modules or the 1RU frame,
which will hold up to three modules.

2. INSTALLATION
The 7713HDC comes with a companion rear plate that occupies one slot in the frame. For information on
inserting the module into the frame see the 7700FR chapter section 3.
Figure 2: 7713HDC Rear Panel Overlay
2.1. VIDEO CONNECTIONS
INPUT Input BNC connector for 10-bit serial digital video signals compatible with the SMPTE 292M or
SMPTE 259M-C standards. (SMPTE 259M not supported at the time of writing.)
DA OUTPUT 1 to 4 These four BNC connectors are used to output reclocked serial component video, in
the same standard as the video input. DA OUTPUT 4 can also be used as a 6 Hz or genlock
input by reconfiguring jumpers on the main circuit board. See section 6.6 and 6.7 for
information on configuring this BNC.
Revision 1.3 7713HDC-3

7700 MultiFrame Manual
7713HDC Downconverter & Distribution Amplifier
COMP/SDI OUT 1 to 3 These three BNC connectors can be individually configured either as
downconverted SDI video outputs, compatible with the SMPTE 259M-C standard, or as
composite analog (NTSC/PAL) video outputs. See section 6.5 for information on selecting the
output type. COMP/SDI OUT 1 can also be used as a genlock input by reconfiguring jumpers
on the main circuit board. See section 6.7 for information on selecting the Genlock source.
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.
GLCK IN There are four possible sources to connect the genlock reference. DA OUTPUT 4 or
COMP/SDI OUT 1 can be used as a genlock input by reconfiguring jumpers on the main
circuit board. (See section 6.7). When the card is installed in a model 7700FR-G frame, the
Genlock source can come from one of the two frame Genlock signals carried on the frame
mid-plane. 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 J21 on the 7713HDC module
selects whether the selected reference input is terminated to 75 ohms (default) or high
impedance. On Rev A and later boards, the Frame Genlock Source menu item is used to
select whether one of the two Frame Genlock signals or the GLCK IN signal will be used.
On Rev 1 boards, there is also a jumper that must be set (See section 6.7). 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 5.3.6) When no Genlock is provided, the output
video is timed with respect to the input video.
2.3. 6 HZ PULLDOWN REFERENCE
For control of the 3/2 cadence on the output video, the downconverter can be locked to a 6 Hz reference
pulse.
6 HZ IN DA OUTPUT 4 / 6 HZ IN can also be configured as a 6 Hz input by reconfiguring jumper
J11 on the main circuit board. (See section 6.6 for information on configuring the BNC as a
6 Hz Input) 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 will normally identify the A frame candidates.

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 (Î) 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 (Í) indicating that you can now
adjust the parameter. Using the toggle switch, adjust the parameter to its desired value. If the parameter
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 (Î). Continue selecting
and adjusting other parameters or use the BACK or EXIT commands.

5.3. CONFIGURING THE VIDEO CONTROLS
The Video menus are used to configure parameters associated with the input and output video standards
and output video timing. Other than the Video Type menu, these menu items are not applicable when a
standard definition input video is connected. The chart below shows the items available in the Video
menu. Sections 5.3.1 to 5.3.6 give detailed information about the menu item.
Video Type Selects if the video input will be High Definition or Standard definition.
Std Selects the video input and output standards.
Genlock Source Selects the genlock source
Reset Input Buffer
Resets the input buffer so that the current video source is the midpoint. The
input can now vary ±1/4 line from the current source without any
disturbance in the output.
Pulldown Reference Selects the reference source when 3:2 pulldown is being added on the
output.
A Frame Offset Sets the offset of the A Frame from the Pulldown Reference when 3:2
pulldown is being added on the output
525 V Phase Offset Sets the vertical phase of the output signal to the NTSC Genlock reference
input.
525 H Phase Offset Sets the horizontal phase of the output signal to the NTSC Genlock
reference input.
625 V Phase Offset Sets the vertical phase of the output signal to the PAL Genlock reference
input.
625 H Phase Offset Sets the horizontal phase of the output signal to the PAL Genlock reference
input.
Set Minimum Delay Sets the output timing to achieve minimum delay.
5.3.1. Setting the Video Input Type
Video
Video Type
Auto
SD
HD
With this control, you can set whether the 7713HDC will function
as a reclocking high definition serial digital video distribution
amplifier and a high quality downconverter for 1.5 Gb/s HDTV
signals or function as a monitoring distribution amplifier for
standard definition 270 Mb/s signals.
When set to Auto, the module will autodetect the input video
type. You can also force it to either high definition mode (HD) or
standard definition mode (SD).
"
When the input video is Standard Definition, the 7713HDC operates as a monitoring
distribution amplifier. In this mode it does not process the audio or vertical interval
data but merely passes it through. Accordingly, the menu items that control these
functions
(
as described in sections 5.3.2 to 5.7
)
have no effect when the 7713HDC
7713HDC-10 Revision 1.3

720p/50 to 625i/50
With this control, you can set the input and output video
standards. This menu item is not applicable when a standard
definition input video is connected.
Note: When set to Auto, the module cannot distinguish between
1080i/59.94, 1080p/29.97sF and 480p/59.94, so it will be treated
as 1080i/59.94. Similarly 1080p/25sF will be treated as
1080i/50.
5.3.3. Selecting the Genlock Source
Video
Genlock Source
Frame Ref. 1
Frame Ref. 2
External Input
If the card is installed in a 7700FR-G frame, two reference inputs are
available on the frame that supplies the genlock signal to every card in the
frame. Either of these two inputs may be selected as reference sources. On
Rev 1 boards you must also set a jumper to enable the Frame genlock
reference. On Rev A and later boards this is done automatically by selecting
the Frame Ref 1 or Frame Ref 2 menu choices.
See section 6.6 and 6.7 for information on selecting the card reference
source and termination. The reference may either be an externally supplied
color black reference signal or you may use the input video as a reference.
On Rev 1 boards this control allows you to select which frame reference will
be used when the jumpers are configured for a Frame genlock reference.
When the jumpers are configured for a BNC reference, this control has no
effect. On Rev A and later boards the Frame Genlock Jumper is replaced
with a switch under menu control. When you select External Input then the
Genlock BNC reference will be used.
!
The Genlock Source adjustments are REAL TIME ADJUSTMENTS and will affect
the output video timing immediately. This setting should not be adjusted when
the output video is in the broadcast chain.

5.3.4. Resetting the Input Line Buffer
Video
Reset Input Buffer
Reset
Cancel
There is a line buffer on the input of the 7713HDC that allows the input to be
switched between feeds that are genlocked, but offset ±1/4 of a line from a
reference point.
When the input buffer is reset, the current video source is set to be the
reference. An upstream router may now switch between feeds that are
offset from this video source by ±1/4 of a line without any visual disruption in
the output video.
!
Resetting the Input Buffer will affect the output video timing. These settings
should not be adjusted when the output video is in the broadcast chain.
5.3.5. 3:2 Pulldown Processing
When using a 1080i/60 or 1080i/59.94 input video feed containing 3:2 pulldown, the 7713HDC
downconverts each field of the incoming image 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/60, 720p/59.94, 720p/50, 480p/60 or 480p/59.94 input video feed the 7713HDC
downconverts each frame of the incoming image 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.
When using a 1080p/24sF or 1080p/23.98sF input video feed the 7713HDC combines each segment of
the incoming image back to a progressive frame before down conversion. When using a 1080p/24 or
1080p/23.98 input video feed the 7713HDC downconverts each frame of the incoming image. After down
conversion, extra fields are inserted to create a 3:2 pulldown at the output. The Pulldown Reference and A
Frame Offset menus are used to determine the cadence of the 3:2 output.

5.3.5.1. Selecting the 3:2 Pulldown Reference with 24 Fps and 23.98 Fps Input Video
"
This menu setting is only used when the input video is 1080p/24, 1080p/23.98,
1080p/24sF or 1080p/23.98sF. In other input video formats it is not applicable.
Video
Pulldown Reference
Auto
RP 188
6 Hz Input
Free Run
On 24 Fps and 23.98 Fps video input formats 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 3). The output of the
A frame candidate frame will be delayed by 2 frames, will consist of two
video fields and will normally be in time with the input. 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 5.3.5.2)
When you select Auto the 7713HDC will auto detect the pulldown reference
according to the following priority:
•
•
•
6 Hz pulse if present
RP188 ancillary time code if present
Free Run pulldown if RP188 is not present
Select RP 188 when the embedded ancillary time code 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 DA OUTPUT 4 / 6 HZ
BNC is used to determine the pulldown. (See section 6.6 for information on
configuring the BNC as a 6 Hz Input) 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 will
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.
5.3.5.2. Accommodating Non-Standard 3:2 Sequences
"
This menu setting is only used when the input video is 1080p/24, 1080p/23.98,
1080p/24sF or 1080p/23.98sF. In other input video formats it is not applicable.
