7740DLY-HD series HD Video Delay
Revision 1.3.1 7740DLY-HD-1
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 one output.
The 7740DLY-HD modules are housed in a 3RU frame that will hold up to 7-7740DLY-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
•Delay programmable in video units (frames, lines, and samples) or as time units (seconds)
•Auto senses video standard
•Bypass relay for program path protection on power loss
•Card edge controls operate on screen menu system to program delay settings
•VistaLINK™ - enabled offering remote control and configuration capabilities via SNMP using
VistaLINK™ Pro or 9000NCP Network Control Panel. VistaLINK™ is available when modules are
used with the 3RU 7700FR-C frame and a 7700FC VistaLINK™ Frame Controller module in slot 1 of
the frame

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: 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-4 Revision 1.3.1
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 autodetected 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 submodule 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 1.

4. STATUS LEDS
The 7740DLY-HD has 2 LED Status indicators on the main circuit board and 2 indicators on the
submodule to show operational status of the card at a glance. Figure 3 and Figure 4 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.
