7710NR-HD-4 Revision 1.1
2.2. GENLOCK REFERENCE
For proper synchronization of the output video, the Noise Reducer must be locked to a genlock signal of
the output video format.
GENLOCK: This BNC is for connecting a video or tri-level sync reference and is auto-detected by the
module. Jumper J21 selects whether the reference input is terminated to 75 ohms or high
impedance (default). (See section 7.3). The Reference menu item is used to select the
correct type of video reference being used. 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
6.3.1) When no Genlock is provided, the output video is timed with respect to the input
video.

4. STATUS INDICATORS
The 7710NR-HD series modules have 3 LED Status indicators on the main circuit board front card edge to
show operational status of the card at a glance. Figure 7-1 shows the location of the LEDs and card edge
controls.
Two large LEDS on the front of the main board indicate the general health of the module
LOCAL FAULT: This Red LED indicates poor module health and will be ON during the absence of a
valid input signal or if a local input power fault exists (i.e.: a blown fuse). The LOCAL
FAULT indication can also be reported to the frame through the FRAME STATUS
jumper.
MODULE OK: This Green LED indicates good module health. It will be ON when a valid input
signal is present, and the board power is good.
VIDEO PRESENT: This Green LED will be ON when there is a valid video signal present at the module
input.
GENLOCK: This Green LED will be ON when there is a signal present at the module genlock
input. This LED will blink to indicate that an incorrect signal appropriate for the
current video format is present.
The large LEDs on the sub-board of the module do not indicate any functionality and will always be Green.
4.1. AUDIO STATUS LEDS
Four LEDs located on the main board on the lower end of the module (near the card extractor) indicate
which audio groups are present in the input video. Audio group LED 1 is located closest to the center of
the module.

6. ON SCREEN MENUS
6.1. NAVIGATING THE ON SCREEN MENU SYSTEM
A toggle switch and pushbutton will allow card edge navigation for a set of on-screen menus used to
configure the card. 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 options, 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 the 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 6.9 provide
detailed descriptions of each of the sub-menus. The tables in sections 6.3 to 6.9 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. The menu item BACK, will return the user to the previous
menu and the menu item EXIT will exit the menu system.

With this control, you can select the line number where VITC will be written
on standard definition output video. The valid range is 10 to 20 for
525i/59.94 inputs, 6 to 21 for 625i/50 inputs.

Video
Loss of Video
Black
Blue
Pass
The user can set the output to go to black, go to blue or pass the input with
this control.
When set to Pass, the output video will be incoherent when the video input
is missing.
6.3.7. Calculating the Delay through the Noise Reducer
The delay through the Noise Reducer is dependent on the video format, the Noise Reducer processing
mode and the V Phase Offset and H Phase Offset settings. There are separate settings of H and V phase
offsets for each output video type.
To achieve the minimum delay use the control Force Minimum Delay. Otherwise the status screen will
report the current true delay of the system.
"The delay is counted in the lines and pixels of the output standard and is
calculated from input field 0 start to output field 0 start.

Force Minimum
Delay This control sets the H Phase Offset and V Phase Offset menu settings
such that the card has the minimum possible input to output delay.
6.3.8. Setting up the Video Output Timing
The output stage of the Noise Reducer contains a frame buffer so that the output video can be timed with
respect to the reference applied to the GENLOCK input when the Reference Select menu item is set to
External. In the absence of a genlock signal, or when the Reference Select menu item is set to Video the
output video will be timed with respect to the incoming Video.
"
The V Phase Offset and H Phase Offset adjustments are REAL TIME ADJUSTMENTS
and will affect the output video timing immediately. These settings should not be
adjusted when the output video is in the broadcast chain.

6.3.8.1. Selecting the Video Reference Source
Video
Reference Select
Video
External
With this control the reference source of video locking is set.
Select External to lock the output video to the reference video applied to the
GENLOCK BNC. If the genlock reference disappears or is not valid, the
card will lock to incoming video.
Select Video to lock the output video to the input video. When there is no
input video the output video will free run.
6.3.8.2. Setting the Vertical Phase of the Output Video
Video
V Phase Offset
0 to Max Lines
0
With this control, you can set the vertical timing of the output video with
respect to the reference input set by the Reference Select menu item.
There are separate settings of V phase offset for each output video type.
Setting this control to 0 keeps the output video frame aligned with the
Genlock reference or incoming video if genlock is missing.
Increasing the value will delay the output video in one-line increments. In
order to advance the vertical timing of the output video with respect to the
genlock video, set the control to the maximum total number of lines of the
output video minus the number of lines that you wish to advance the output
video. (E.g. for 1080i/59.94 output video the total number of lines is 1125,
so to advance the output video 5 lines set the value to 1120.) When
increasing the V Phase Offset value causes it to go beyond the limit of the
frame buffer, the V Phase Offset will wrap to the beginning of the frame
buffer, resulting in a change of one frame of throughput delay between the
HD/SD input and the video output.
6.3.8.3. Setting the Horizontal Phase of the Output Video
Video
H Phase Offset
0 to Max samples
0
With this control, you can set the horizontal timing of the output video with
respect to the reference input set by the Reference Select menu item.
There are separate settings of V phase offset for each video type. Setting
this control to 0 keeps the output video line aligned with the Genlock
reference.
Increasing the value will delay the output video in one-sample increments.
In order to advance the horizontal timing of the output video with respect to
the genlock video, set the control to the maximum number of samples per
line for the output video standard minus the number of samples that you
wish to advance the output video. (E.g. for 1080i/59.94 input video the total
number of samples per line is 2200, so to advance the output video 5
samples set the value to 2195.)
