Model 7910 HD Upconverter And Cross Converter
MODULE OVERVIEW
The 7910 module is an SD to HD Upconverter with a standard definition SDI input and
four HD SDI outputs. The 7910 also provides Cross Conversion when an HD signal is
connection to its SD In BNC. The module is excellent for on-air use or in an HD island, in
a signal ingest installation, or in a production application. Refer to the functional block
diagram for the module on the next page.
Sophisticated Adaptive Noise Reduction ensures delivery of a pristine output that is
excellent for use in broadcast. Picture Detail Enhancement is used to recover information
that has been lost due to poor frequency response upstream. Different aspect ratio conversion choices are available for selection on the HD output.
Input standard and frame rate are auto-detected. The 7910 automatically adjusts from SD
to HD color space and gamma. The built-in Proc Amp provides adjustment of signal
parameters with controls for Video Gain, Chroma, Pedestal, and Hue.
HD closed captioning is carried in data packets in the vertical interval ancillary data
space. The 7910 properly translates between traditional SD captioning (line 21 or 23) and
HD caption data so that closed captioning content is converted transparently between
video standards and formats.
The converted output is timeable with respect to the reference input. When converting to
film rate (1080sF/23.98) formats, 3:2 pulldown cadence is automatically detected and
backed out when present in the input. 3:2 detection can be enabled and disabled.
One of three types of audio submodules can be installed on the main circuit board:
• The 8415 is a 8 channel audio submodule with AES I/O that provides management
of embedded audio in the processing path, or supports audio embedding/disembedding
alongside the video processing elements. Embedded audio is safely bypassed
around the video frame store with lip sync preserved. Level adjustments and
channel shuffling are accessed through the built-in audio mixer. All audio
processing is performed at full 24 bit resolution by a digital signal processor (DSP).
• The 7610 audio submodule provides carriage of up to eight channels of embedded
audio through the format conversion process. Embedded audio in the input signal
is delayed to match the video delay and preserve lip sync. The delayed content is
reinserted in the video output. No level adjustment or channel swapping is
provided.
• The 7615 audio submodule also provides processing for signals with eight channels
of embedded audio. It offers the same processing and AES I/O as the 8415 plus the
ability to decode Dolby-E signals.
The 7910 can be configured locally or controlled and configured remotely with Avenue
Touch Screens, Express Panels, or Avenue PC Software. Alarm generators, configurable
user levels, module lock out, and customizable menus are just some of the tools included
in the Avenue Control system.
The on-board CPU can monitor and report module ID information (slot location, software
version and board revision), power status, and ancillary data 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.

Power is derived from the ± 12 volt frame power. It is regulated to the required +5 volts
for the module by an on-board regulator. The module is fused with a resettable fuse
device. If the fuse opens due to an overcurrent condition, the module will lose power. After
pulling the module, the fuse will reset automatically requiring no replacement fuse.
Modules at software version 2.2.0 or later support SNMP (Simple Network Management
Protocol) monitoring. For each applicable signal processing module, module, signal, and
reference status are reported. For complete details on using SNMP monitoring, refer to
the Avenue System Overview in the manual that accompanies each frame.
APPLICATIONS
SD Upconversion
The 7910 module can be utilized to upconvert SD video from many different source types,
or cross convert HD video into all popular variations of 1080 and 720.
As shown in the example below, the SD ingest signal from a satellite is fed to a 7910
module where it is upconverted to feed an HD Master Control Switcher. The other three
outputs can be sent to other HD destinations.
Along with accurate upconversion, the module provides sophisticated adaptive noise
reduction for noisy input signals for use in broadcast applications. Timing to a house
reference is available on the module, along with many other controls features for ensuring
a clean, stable signal.

APPLICATIONS
HD Cross Conversion
The 7910 module can be utilized to cross convert between HD 1.5 Gb/s formats, processing
all popular variations of 1080 and 720, making it simple for facilities to ingest any type of
HD signal. As shown in the example below, the 1080i input from an HD network feed is
fed to the 7910 where the format is converted to 720p as required for input to an HD router.
Auto Sensing Upconversion And Cross Conversion
The 7910 can either upconvert or cross convert as needed. As shown below, the output of
the 7910 has been set to 1080i. In this setup, the video server could, for example, play 720
or 1080 program material then play SD commercials. The 7910 will accept SD or HD
inputs and automatically convert to 1080i..

INSTALLATION
Audio Submodule Installation
The optional audio submodules install on the component side of the 7910 module circuit
board. If a submodule is ordered with the 7910, that module will come pre-installed.
To install an audio submodule manually, locate the three connectors on the left side of the
circuit board as shown below and line the connectors up, checking their alignment. Press
carefully into place to seat the submodule.
7910 Video Processing Module
Plug the 7910 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 below for cabling
instructions. Unless stated otherwise, the 1 RU cabling explanations are identical to those
given in the 3 RU diagram.

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.
Configuration parameter choices for the module differ between Remote and Local modes.
In Remote mode, choices are made through software and allow more selections. The 7910
Parameter Table on page 9 summarizes and compares the various configuration
parameters that can be set remotely or locally and the default/factory settings. It also
shows the default User Levels for each control. These levels can be changed using the
Avenue PC application
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 on page 11. The Local switches are inactive when the Remote/Local
switch is in the Remote position.
In Remote mode, Avenue module parameters can be configured and controlled from one of
the remote control options, the Avenue Touch Screen, Avenue Express Control Panel, or
the Avenue PC Application. Once the module parameters have been set remotely, the
information is stored on the module’s CPU. This allows the module to be moved to a
different slot in the frame at your discretion without losing the stored information.
To set parameters remotely using the Avenue PC option, refer to the Avenue PC Remote
Configuration section on page 12.
To set parameters remotely using the Avenue Touch Screen option, refer to the Avenue
Touch Screen Remote Configuration section on page 23.
Express Panel operation is described in the data pack that accompanies the control panel
option.
