• One SDI 525 or 625, 270 Mb/s component digital program video input.
• Video input relay bypass for power failure bypass protection.
• One SDI 525 or 625, 270 Mb/s component digital Key video input.
• One composite analog video output with On Screen Menu text.
• 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 64 line patterns may be captured from any key input line and stored in User Memories for later
insertion on any VBI line.
• Extensive library of Factory preset test signals.
• Each line of VBI independently programmable to pass, blank, insert from key signal, insert from user
memory or insert factory test signal.
• On Air Preset configuration selected with GPI or Menu 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, A.M.O.L. encoders, VITS inserters, data encoders, etc. are typically connected in
series in the program output so that if one unit fails the network output will fail. The 7725VBI-K allows you
to have one point of insertion in the program output path.

1.2. SQUEEZE BACK CC BYPASS
This application shows Line 21 caption squeeze back bypass also known as VBI 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. The 7725VBI-K device will provide a bypass of VBI
around the processing device.

2. INSTALLATION
The 7725VBI-K comes with a companion rear plate that has five BNC connectors and one 25 pin female D
connector. Modules occupy two slots in the 7700FR-C frame. For 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 Rear Panel
2.1. VIDEO IN AND OUT
FILL This BNC connector is used to supply the signal that you want to insert into the VBI of the
program video. Supply a 10-bit serial digital video signal compatible with the SMPTE 259M-C
standard. This input will be referred to as the Key input throughout this manual.
PGM Input BNC connector is used to supply the program video to the inserter. Supply a 10-bit serial
digital video signal compatible with the SMPTE 259M-C standard.
SDI OUTPUT There is one BNC connector that contains the PGM input video with the VBI signals

7725VBI-K-4 Revision 1.3
ANALOG OUTPUT This BNC connector contains the PGM input video with the VBI signals as an
analog composite video signal and is used for monitoring purposes. The analog output is also
used to display the On Screen programming menu.
2.2. GENERAL PURPOSE INPUTS
Table 2-1 shows the pinout of the 25 pin Female D GPI connector. The GPI’s are active low with internal
pull up resistors (4.7k Ohms) to +5V.
To make an input active, lower the signal to near ground potential (i.e. connect to shell or chassis ground).
This can be done with a switch, relay, TTL drive, GPO output or other similar method. 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)
