MODULE OVERVIEW
The 5420 Digital Logo Inserter module allows the keying (insertion) of a graphic image or
animation sequence over a serial digital program background. The keying operation is an
additive linear key with a density (transparency) control.
Three modes of operation are available: DSK, DSK Preview, or Fill/Key. In DSK mode, the
module keys the graphic over the serial digital background and outputs the entire signal
on the PGM output BNCs. In the DSK preview mode, selecting a new event causes an onair event to transition off. The new event is sent to the PVW output but not transitioned
on-air. Activating the Cut or Mix control puts the event on-air and also feeds it to the
PVW output. In Fill/Key mode, two serial digital outputs are provided so the module can
source a key and fill to a switcher’s DSK input if desired.
Graphic stills, logos and animation sequences can be authored in targa format with any
computer software desired. These stills, logos and animation sequences are collected and
named with a PC application called Avenue Logo that comes on a CD with the module.
They are then downloaded to non-volatile flash memory on the module using the application. Each image is stored in flash memory which can store up to 5 full frame images or
many smaller images, depending on their size. Total available storage is about 2 M pixels
or 8 MB. An average corner logo is approximately 100 x 100 pixels in size for a total area
of about 10,000 pixels, allowing the 5420 to store up to 200 average size logos. Each frame
in an animation sequences is considered one logo. Animation sequences can be up to 200
frames long (approximately 6.5 seconds in 525 mode).
Each logo can be defined by number, name, type and can be positioned horizontally and
vertically on an image by image basis using Avenue Logo or the Avenue remote control
system. In and out transition times can also be programmed for each image. A density
control allows changing the transparency of the key. These values are then stored for each
logo.
Images can be defined as events that can be cut or mixed on manually or triggered to
come on by GPI control from an external control device. Up to eight events can be defined
to correspond to the eight GPI inputs available on the Control connector on the rear of the
module. The 5815 Remote GPI panel can also be used to control the GPIs. GPI trigger 8
can be programmed to act as a regular GPI trigger or as a cut or mix control to transition
one of the other selected GPIs (1 – 7) as a cut or mix.
As shown in the 5420 functional block diagram on the following page, a serial digital background signal is fed to the module and enters a receiver/decoder circuit where it is
monitored for cable equalization and EDH processing. The reclocked background signal is
available from a loopback output BNC if needed. EDH status is reported for the input
signal.
The processed background signal then enters a linear keying circuit where the selected
key image cuts a hole in the background and the fill signal is added. When configured for
DSK mode, the background is added to the fill and a composited image of background with
key is available from the PGM output BNCs. Timing for the output signal is derived from
the serial input.
DSK w/Preview mode places the background and fill on the PVW output to be viewed
before being cut or mixed on-air as the next event.

Model 5420 Digital Logo Inserter
When the module is configured for Fill/Key mode, black is added to the fill instead of the
background signal and the timing reference is selectable from the external video reference
BNC, the master frame reference or the serial input. The separate Fill and Key signals go
to their respective output BNCs for feeding a device such as a switcher. When an image is
selected as a key, it is directly transferred to the linear keying circuit.
The on-board CPU can monitor and report module ID information (slot location, software
version and board revision), and power status to the optional frame System Control
module. This information can be accessed by the user or set to register an alarm if desired
using the remote control options available.
Because the 5420 is an Avenue module, every function and parameter can be controlled
from an Avenue Touch Screen Control Panel, Avenue Express Panel, or the Avenue PC
Control Application. Memory registers can be used to save the complete configuration of
the module, making it easy to change instantly between different configurations.

APPLICATIONS
The 5420 module can be utilized in many ways to take advantage of its versatility. Some
keying tasks that can be performed by the 5420 include the following:
• Fixed or animated station and channel ID
• Copyright protection
• Emergency standby notification
• Gateway for downstream keys and masks from a graphic workstation
• Custom full-field test patterns/zone plates
The module can operate in DSK mode, DSK w/Preview, or Fill/Key mode. Examples of
common applications are given here.
DSK Mode
When the module is configured for DSK mode, a serial digital signal from a device such as
a Master Control switcher can be connected to the input and a graphic or logo from a PC
workstation can be inserted over the background to provide the final video as shown in
the example below. The PGM outputs can be fed to the transmitter and other destinations
and PVW outputs are available for monitoring.

Fill/Key Mode
When the module is configured for Fill/Key mode, the background and key signal can be
used to supply separate Fill and Key signals to feed a Master Control switcher as an input
source, in a similar manner as a character generator. The 5420 can be genlocked to an
external reference to match the timing of the Master Control device as shown below.

INSTALLATION
Plug the 5420 module into any one of the slots in the 1 RU or 3 RU frame and install the
plastic overlay provided onto the corresponding group of rear BNC connectors associated
with the module location. Note that the plastic overlay has an optional adhesive backing
for securing it to the frame. Use of the adhesive backing is only necessary if you would
like the location to be permanent and is not recommended if you need to change module
locations. This module may be hot-swapped (inserted or removed) without powering down
or disturbing performance of the other modules in the system.
CABLING
Refer to the 3 RU and 1 RU backplane diagrams of the module on the following page for
cabling instructions. Note that unless stated otherwise, the 1 RU cabling explanations are
identical to those given in the 3 RU diagram.
Control Devices
In addition to GPI access through the control system, the module provides eight GPI input
contact closures and control from a dedicated serial port both accessible through the
15-pin D Control connector on the corresponding rear slot of the frame.
Three types of devices can control the eight GPI inputs to the 5420 module; the Avenue
5815 GPI Control Panel, a customer-supplied GPI device and an external device (such as a
PC) using a Serial port connection. Connection of the 5815 GPI Control Panel and the GPI
device to the 5420 module and the cable pinouts for each application are given in the next
sections. Refer to Appendix A for the details for connecting an external device such as a
PC, including the serial protocol.

Avenue GPI Remote Control Panel
Connect an Avenue 5815 GPI Control Panel from the rear of the control panel (either
DB 9-pin male) to the Control connector on the rear of the 5420 module (HDB 15-pin
male). The pinout for this connecting cable is given below.
The 5815 GPI Control Panel can be rack-mounted in a standard 19 inch equipment
rack. Connect the universal in-line power supply provided to the connector at the left
rear of the GPI panel. The power supply is auto-sensing and requires no adjustments.
Up to eight Avenue 5815 GPI Control Panels can be connected in parallel for GPI
control. Panels are connected together via the DB 9-pin loop-through connectors on
each panel. The cable to connect each panel is a DB 9-pin male to DB 9-pin male with
straight pin-to-pin connections as shown in the illustration below. This cable may be
purchased at any electronics supply store or constructed from the diagram. Note not
all pins are necessary for control panel connection but all pins can be connected.
