MODULE OVERVIEW
The 5470 module is a full-featured serial digital processing amplifier designed for
adjusting and legalizing 601 sources. All processing is done in the digital domain, ensuring
a pristine output. When set to unity, the 5470 is completely transparent. An optional 5475
Digital Noise Reducer submodule can be added to remove unwanted noise and artifacts.
Processing controls include level adjustment, NTSC style hue rotation, along with video,
chroma and setup. Black and White clips can be set as desired. The Detail Enhancer
recovers information that has been lost due to poor frequency response in upstream
systems. A Split Screen mode allows comparing the processed output with the original
non-processed input.
Several forms of noise reduction are employed with the 5475 DNR option to ensure the
best possible performance. Horizontal filtering is used to remove high frequency and
impulse noise and to limit bandwidth for MPEG encoding. Recursive Temporal Noise
filtering includes Simple Recursive, Motion Adaptive and Motion Adaptive with impulse
filter. Controls are provided for maximum signal to noise improvement and for noise
threshold. These can be set manually or run in automatic mode.
As illustrated in the block diagram on the next page, the serial input signal enters the
module and passes through receiver and serial decoder circuitry where the input stream is
deserialized and EDH information is monitored. The serial output of the receiver is routed
to the reclocked Loop Out BNC on the rear of the module. It is also directed by the user to
either the processing circuitry for adjusting gains, pedestal, black levels and hue or,
through the bypass path to the serial outputs if no processing is desired.
When the optional 5475 DNR (Digital Noise Reduction) submodule is installed, the processing continues through dynamic noise reduction and filtering circuitry based on
controls set by the user.
The next processing stage is composed of detail enhancing filters which allow recovery of
information lost due to poor frequency response in upstream systems. Controls are
provided for setting luminance and chrominance sharpness values.
The final digital processing stage is the Legalizer and clip circuitry. Clip adjustments for
black/white and chroma high/low levels are provided in the menus. Certain values represented in serial digital component may be illegal in the NTSC or PAL domains. The 5470’s
Predictive Composite Clipper mode looks for and alters those values that would be illegal
in analog composite, ensuring the output can be used for transmission.
The output stage of the module inserts and updates EDH before the signal is distributed
to the four Serial Output BNCs on the rear of the frame.
Embedded audio and ancillary data can be passed or stripped as directed by the user. If
the video processing path has any delay, the embedded audio is delayed accordingly.
Five memory registers are provided on the module for storing module setups. Different
setups can be created and stored for particular applications if needed or factory default
setting can be recalled at any time.
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.

APPLICATIONS
As shown in the example below, a typical use for the 5470 module would be for conditioning a potentially noisy 601 signal source, such as a satellite feed. After removing errors
and legalizing the signal it can then be distributed to analog and digital sources within
legal limits for all types of applications.
INSTALLATION
Plug the 5470 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.

MODULE CONFIGURATION AND CONTROL
The configuration parameters for each Avenue module must be selected after installation.
This can be done remotely using one of the Avenue remote control options or locally using
the module front panel controls. Each module has a REMOTE/LOCAL switch on the
front edge of the circuit board which must first be set to the desired control mode.
The configuration parameter choices for the module will differ between Remote and
Local modes. In Remote mode, the choices are made through software and allow more
selections. The 5470/5475 Parameter Table on the following pages summarizes and
compares the various configuration parameters that can be set remotely or locally and the
default/factory settings.
If you are not using a remote control option, the module parameters must be configured
from the front panel switches. Parameters that have no front panel control will be set to a
default value. The Local switches are illustrated in the Front Panel Controls and
Indicators section following the 5470/5475 Parameter Table.
Avenue module parameters can be configured and controlled remotely from one or both of
the remote control options, the Avenue Touch Screen or the Avenue PC Application. Once
the module parameters have been set remotely, the information is stored on the module
CPU. This allows the module be moved to a different cell in the frame at your discretion
without losing the stored information. Remote configuration will override whatever the
switch settings are on the front edge of the module.
For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC
Remote Configuration section of this document.
For setting the parameters remotely using the Avenue Touch Screen option, refer to the
Avenue Touch Screen Remote Configuration section of this data pack following
Avenue PC.

The Legalizer menu allows you to enable the Legalizer function to limit the input signal
black and white clip levels and the chroma clip levels with the following controls:
• Legalizer – set the legalizer function to one of the following:
Off – to disable it.
Legal – to apply the following factory preset parameters:
• B/W Clip is On.
• Black Clip is set to – 2.5 IRE.
• White Clip is set to + 105 IRE.
• Chr Clip Mode is Predictive Composite.
• Chr Lo Clip is set to – 20 IRE.
• Chr Hi Clip is set to + 120 IRE.
Custom to use the controls described below to set custom parameters.
• B/W Clip – select On to enable Black and White Clip functions or Off to
disable them.
• Black Clip – set the threshold for the black clip level to between – 8 and +
6.2 IRE (no content will be allowed below the level set).
• White Clip – sets the threshold for the white clip level to between 95 and
110 IRE (no content will be allowed above the level set).
• Chr Clip Mode – select Off for no chroma clip functions. Select Chroma to
use the Chr Lo Clip and Chr Hi Clip controls to clip the chroma content
(irrespective of the luminance). Select Cpst to enable the Predictive
Composite Clipper. This mode allows you to ensure that when the signal is
encoded to PAL or NTSC the minimum and maximum chroma excursions do
not exceed preset levels. Because in composite video, the chroma rides on
the luminance, this clip mode is based on chroma and luminance values.
