1. OVERVIEW
The 7740DLY-HD series modules are full function HD Video Delay modules designed for applications
such as: satellite uplink, signal re-entry on master control inputs, at cable headends, mobile vehicle
outputs, broadcast transmitter inputs, virtual sets and matching delays caused by multi-channel audio
compression.
There are two models available with different amounts of delay possible. The 7743DLY-HD also can act
as a delay for standard definition SMPTE 259M video. Both versions will be referred to as the 7740DLY-
HD throughout this manual except where there are specific differences in the products.
Model Video Standard Delay Range
7742DLY-HD
(Discontinued) HD SDI (SMPTE 292M) 37 µs up to 1.6 seconds
SDI (SMPTE 259M) 65 µs up to 16.5 seconds
7743DLY-HD HD SDI (SMPTE 292M) 37 µs up to 3.3 seconds
" As of July 2004 the 7742DLY-HD has been discontinued, but the documentation is
included here for customers with existing units.
The 7740DLY-HD modules will delay all VBI and Ancillary data including embedded audio along with the
video. The delay can be set in frames, lines and samples or in seconds.
With the broadcast environment in mind, the modules feature bypass relay protection to one output.
The 7740DLY-HD modules are housed in a 3RU frame that will hold up to seven 7740DLY-HD series
modules or a 1RU frame that will hold up to 3 modules.
Features:
•Full signal delay capability including VBI and ANC DATA for SMPTE 292M (1.5Gb/s) signals
•7743DLY-HD also supports full signal delay capability including VBI for SMPTE 259M (270Mb/s)
signals

2. INSTALLATION
The 7740DLY-HD series modules come with a companion rear plate that has 4 BNC connectors and a 25
pin D connector and occupy two slots in the frame. For information on mounting the rear plate and
inserting the module into the frame see the 7700FR chapter section 3.
Figure 2-1: 7740DLY-HD Series Rear Panels
2.1. VIDEO CONNECTIONS
HD INPUT (VIDEO INPUT): Input BNC connector for 10-bit serial digital video signals. The
7742DLY-HD supports signals compatible with the SMPTE 292M
(1.5 Gb/s) standard. The 7743DLY-HD supports signals compatible
with the SMPTE 259M (270 Mb/s) and SMPTE 292M (1.5 Gb/s)
standards.
HDI OUTPUT (VIDEO OUTPUT): Two BNC serial digital video outputs are provided. Output 1 is
protected by a bypass relay, which will activate in the event of power
loss to the module. The remaining output is not bypass protected.

7740DLY-HD series HD Video Delay
7740DLY-HD - 4 Revision 1.5
2.2. GENLOCK REFERENCE
GENLOCK: This BNC is used to connect a video or tri-level sync reference. The genlock signal may be
NTSC or PAL colour black, or tri-level sync and is auto-detected by the module. The
genlock standard must be set using the DIP switches 1 to 3. (See section 5.1) Jumper J9
on the 7700CC sub-module selects whether the reference input is terminated to 75 ohms or
high impedance (default). (See section 8.3). The output video can be timed with respect to
the genlock video using the Reference Phase menu items. (See section 7.2.1) When no
Genlock is provided, the output video is timed with respect to the input video. In order to
meet the jitter tolerance specifications outlined in section 3.2 a genlock reference must be
applied.
2.3. GENERAL PURPOSE INPUTS
A 25 pin D connector labeled GPI contains 8 GPI inputs. The connector pinout is shown in Table 2-1.

4. STATUS LEDS
The 7740DLY-HD has 2 LED Status indicators on the main circuit board and 2 indicators on the sub-
module to show operational status of the card at a glance. Figure 8-1 and Figure 8-2 show 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 the board power
is good and the module is running normally.
Two LEDs on the sub-module (7700CC) indicate the presence of the video input and genlock signals.
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 does not indicate that a correct signal appropriate for the current
video format is present. Refer to Table 5-2 for valid Video format and input Genlock
combinations.

7. USING THE ON SCREEN MENU
An On screen menu (OSD) is used to configure many of the module’s parameters. The three position,
return to center, toggle switch and momentary pushbutton located on the front edge of the module are
used to navigate the OSD setup menus and configure the card’s various controls.
To enter the OSD menu system, press and hold the pushbutton and then press the toggle switch up for 3
seconds. 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.
On all menus, there is a selectable item Done. Selecting Done will take you to the previous menu (the one
that was used to get into the menu). If you are at the top level of the menu tree then selecting Done will
exit the OSD menu and return the module to the normal operating mode.
Once you are in a sub-menu, there may be another menu level, 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 next option with the
same procedure as in the main menu.
If there is a list of parameters to adjust, 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 (<) 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. If the parameter contains a list of choices, you can cycle through the list by pressing
the toggle switch in either direction.
When you have stopped at the desired value, depress the pushbutton. This will update the parameter with

The VIDEO DELAY menu item allows the user to set the video delay. The maximum delay is
approximately 1.6 seconds even though it is set using video units (frames, lines and samples). The video
delay is set using frame, line or sample increments. Each time the pushbutton is pressed to accept a
portion of the total delay, the new video delay will be implemented.
Frame = xxx Sets the amount of delay in whole numbers of frames.
Line = yyy Sets the amount of delay in whole numbers of lines.
Sample = zzz Sets the amount of delay in samples.
Done Return to main menu.
Delay = ttt.ddd sec Displays the amount of delay in seconds.
Step 1: Coarse Adjustment (Frame)
Press the toggle switch up or down until the right arrow (>) is beside the Frames menu item. Press the
pushbutton to set the whole frame delay. The display will show frames = xxx where xxx is the frames
part of the delay value. Press the toggle switch up or down to adjust the value. Holding the toggle switch
will change the value at a faster rate. Press the pushbutton to accept the video frames part of the delay.
The arrow (>) will appear back at the left side of the display.
Step 2: Medium Adjustment (Line)
The line delay adjustment delays the entire line of the video bit stream, including the blanking
portion/HANC. Press the toggle switch down until the right arrow (>) is beside the Lines menu item. Press
the pushbutton to set the whole line delay. The display will show line = yyy where yyy is the lines part
of the delay value. Press the toggle switch up or down to adjust the value. Holding the toggle switch will
change the value at a faster rate. Press the pushbutton to accept the video lines part of the delay. The
arrow (>) will appear back at the left side of the display.

7.2. CONFIGURING THE VIDEO OUTPUT PHASE
The Reference Phase menus are used to the output video timing. The chart below shows the items
available in the Reference Phase menu. Sections 7.2.1.1 to 7.2.1.2 give detailed information about each
of the menu items.
V Sets the vertical phase of the output signal to the genlock reference input.
H Sets the horizontal phase of the output signal to the genlock reference input.
7.2.1. Setting up the Video Output Timing
The output stage of the 7740DLY-HD contains a frame buffer and a line buffer so that the output video can
be timed with respect to the reference applied to the GENLOCK input BNC. In the absence of a genlock
signal the output video will be timed with respect to the incoming Video.
!
The V and H phase 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.

7740DLY-HD - 16 Revision 1.5
7.2.1.1. Setting the Vertical Phase of the Output Video
Reference Phase
V
1 to Max Lines
1
With this control, you can set the vertical timing of the output video with
respect to the genlock reference input. There are separate settings of V
phase offset for each output video type. Setting this control to 1 keeps the
output video in time with the Genlock reference or incoming video if genlock
is missing.
Increasing the value will delay the output video in one-line increments of the
output video standard. 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.) If 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 video input and the video output.
7.2.1.2. Setting the Horizontal Phase of the Output Video
Reference Phase
H
0 to Max samples
0
With this control, you can set the horizontal timing of the output video with
respect to the genlock reference input. There are separate settings of V
phase offset for each output video type. Setting this control to 0 keeps the
output video in time 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 output video the
total number of samples per line is 2200, so to advance the output video 5
samples set the value to 2195.)
