1. OVERVIEW
The 7725VBI-K-HD module is a multi-function VBI keyer. Every program input vertical interval video line
can be programmed to pass upstream video, blank the line, insert any VBI line from the HD/SD Fill input,
insert a selectable VITS (vertical interval test signal) for SD, and insert user selected data such as Wide
Screen Signaling (WSS) and Active Format Description (AFD). The 7725VBI-K-HD allows for up to 70
lines to be programmed. The module provides the capability to store different VBI configurations as
presets and recall them from the On-Screen Display (via Program Monitor Out), VistaLINK®, or via 8 opto-
isolated GPI inputs.
The 7725VBI-K-HD has two re-clocked program outputs and one program monitor output. The module is
often used in critical on-air applications and hence bypass relay protection of the program video path is
provided. The 7725VBI-K-HD is setup via the On-Screen Display or VistaLINK®.
VistaLINK®enables remote monitoring, control and configuration capabilities via Simple Network
Management Protocol (SNMP). This offers the flexibility to manage operations including signal monitoring
and module configuration from SNMP enabled control systems (Manager or NMS) locally or remotely.
The 7725VBI-K-HD occupies one card slot in the 3RU 7700FR-C frame, which will hold up to 15 1-slot
modules or the 1RU 7701FR frame, which will hold up to three 1-slot modules.
Features:
•One serial digital 1.5 Gb/s HD input per SMPTE 292M, or 270 Mb/s SD input per SMPTE 259M
•Two re-clocked HD or SD program outputs
•Video input relay bypass for power failure bypass protection
•One HD input or SD input digital Fill video input
•One HD or SD monitor program output with On-Screen Display
•A comprehensive on screen menu is available to configure the various features of the module
•128 different presets for storing VBI keying configurations
•Up to 16 line patterns may be captured from any fill input line and stored in User Memories for later
insertion on any VBI line
•Up to 70 lines of output video can be programmed
•Each line of VBI independently programmable to pass, blank, insert from fill signal, insert from user
memory or insert factory test signals
•On-Air Preset configuration selected with GPI, OSD, or VistaLINK®selection
•Non-volatile memory protects current configuration in case of power loss
•Fully hot-swappable from front of frame

The following sections outline several possible applications.
1.1. MASTER CONTROL OUTPUT CHAIN PROTECTION
Typically there are several units "chained" together on the output of a master control switcher. Units such
as caption encoders, AMOL encoders, VITS inserters, data encoders, etc. are typically connected in a
series in the program output so that if one unit fails the network output will fail. The 7725VBI-K-HD allows
you to have one point of insertion in the program output path.

1.2. VANC BRIDGING
Some processing devices modify or destroy VBI data such as captioning or VITC. An example of this
occurs with some DVE's during a squeeze back application or with HD colour correction. The 7725VBI-K-
HD device will provide a bypass of VBI around the processing device.

2. INSTALLATION
The 7725VBI-K-HD comes with a companion rear plate that has five BNC connectors and one 9 pin
female D connector. Modules occupy one slot in the 7700FR-C frame. For more information on mounting
the rear plate and inserting the module into the frame see section 3 of the 7700FR chapter.
Figure 2-1: 7725VBI-K-HD Rear Panel
2.1. VIDEO IN AND OUT
PGM IN: Input BNC connector for 10-bit serial digital signals compatible with the SMPTE 292M or
SMPTE 259M-C standards. This BNC connector is used to supply the program video to the
module.
FILL IN: Input BNC connector for 10-bit serial digital signals compatible with the SMPTE 292M or
SMPTE 259M-C standards. This BNC connector is used to supply the signal that you want
to insert into the VBI of the program video. This input will be referred to as the Fill input
throughout this manual.
PGM OUT: There are two BNC connectors that contain the PGM input video with the VBI signals
inserted. One of these outputs (marked as BYPASS) is protected by a bypass relay, which
will activate in the event of power loss to the module.
7725VBI-K-HD-4 Revision 1.2

7700 MultiFrame Manual
7725VBI-K-HD Vertical Blanking Interval Signal Inserter
MON OUT: This BNC connector contains the PGM input video with the VBI signals and is used for
monitoring purposes. The HD/SD output is also used to display the On Screen Display.
2.2. GENERAL PURPOSE INPUTS
Table 2-1 shows the pinout of the 9 pin Female D GPI connector. The GPI inputs are active low. This
means that if you leave an input floating (not connected) then it will not be activated. The user can
activate GPIs simply by connecting the GPI input pins to Ground using a button, switch, relay or an open
collector transistor. The inputs are internally pulled up to either +5 or +12 volts DC set by jumper J16.
Figure 2-2 shows the input circuit for the General Purpose inputs. The GPI Mode menu item is used to
configure the operation of the GPI inputs. (See section 5.7)

There are two large LEDs that indicate the general health of the module.
LOCAL FAULT: This Red LED indicates poor module health and will be On if a local input power
fault exists (i.e.: a blown fuse) or if the module fails to boot (e.g.: upgrade jumper left
on). 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 has booted successfully.
The remaining LED status indicators are listed below:
HEARTBEAT (RUN): This Green LED will be blinking when the module is operating normally.
PGM PRESENCE: This Green LED indicates the presence of a signal on PGM IN.
PGM LOCKED: This Green LED indicates a valid standard on PGM IN.
FILL PRESENCE: This Green LED indicates the presence of a signal on FILL IN.
FILL LOCKED: This Green LED indicates a valid standard on FILL IN.
The other 4 LEDs near the card extractor are for future use.
4.2. DIP SWITCHES
The 7725VBI-K-HD has a set of DIP switches accessible from the card edge. These are currently
reserved for future use.

5. ON SCREEN MENUS
5.1. NAVIGATING THE ON SCREEN MENU SYSTEM
A toggle switch and pushbutton at the front card edge are used to navigate a set of on-screen menus,
which are 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. There is also a line of text at the bottom of the screen to
give instructions about the function of the menu item. 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
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 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.
Throughout the descriptions of the On Screen Menu items, default values are shown in underlined text.

5.4. CONFIGURING USER CAPTURE LINES
The 7725VBI-K-HD has the ability to capture up to 24 line patterns from any VBI line of the fill and store
them in memory locations for later insertion on any VBI line of the program video. The User Capture Line
menu is used to capture signals to the various user memories. Sections 5.4.1 to 5.4.3 gives detailed
descriptions of the menu items.
Fill Video Line Number Selects the line number of the fill video signal that will be captured.
