Clearly, Ensemble wants to be in the broadcast equipment business. It’s so rare anymore to nd a company of this
caliber that has not been gobbled up by a large corporation. They are privately held so they don’t have to please the
money people. They really put their eorts into building products and working with customers.
I’m really happy with the Avenue products and Ensemble’s service, and even more important my engineers are happy.
We’ve continued to upgrade the product and add more cards. We will be rebuilding our production control room and
we will use Avenue again.

Model 7435 and 9455 Clean and Quiet Protection Switches
Module Overview
The 9455 and 7435 modules are clean and quiet protection switches for critical broadcast and satellite
feeds. They switch cleanly between asynchronous sources which means they can be used live to air.
Each module has a full video frame synchronizer, rather than a line delay, ensuring perfect alignment
of mis-timed and non-synchronous SDI sources. The 7435 supports 1.5 Gb/s HD SDI and SD SDI signals.
The 9455 additionally supports 3 Gb/s HD SDI.
When a fault is detected in the primary input, and the secondary input is veried as good, the switch
will activate, causing the secondary input to be switched cleanly and quietly to the module’s output.
The 9455 and 7435 include fail-safe bypass which connects the primary input directly to one module
output. This passive, fail-safe path ensures that there is an output even in the event of a total
power failure.
Clean and quiet switching between sources requires that the sources be synchronous and precisely
timed to each other. The 9455 and 7435 accomplish this automatically, with integral frame
synchronization of the inputs, allowing operation with both synchronous and asynchronous (wild)
sources. This frame synchronization feature not only means that the output will always be stable and
glitch-free, but it also means that in the event of a total loss of both inputs, consistently timed color
black will still be output.
The internal frame synchronizers can be genlocked to an external reference signal so that the
output of the 9455 or 7435 is synchronous to local sources. Alternately, in teleports, headends, and
other multi-service facilities, where there is no logical common reference, the module will internally
generate an accurate reference.
The delay through the 9455 or 7435 can be adjusted up to six frames, with independent control for
the primary and secondary input paths. By operating with several frames of delay, the fault detection
algorithms are given enough time to detect a failure in an input signal and switch to the backup
before the fault has actually appeared on-air.
Dierent types of signal testing (vetting) can be enabled on the module. This happens automatically
and independently for the primary and secondary inputs. The health of the video signal is determined
by monitoring crucial parameters in order of increasing complexity; Timing Reference Signal (TRS), or
a persistent loss of digital sync is tested rst. Black, Embedded Audio and Freeze are also evaluated.
Each test can be congured by the user. For example, the sophisticated Black Detector includes
congurable parameters for black level threshold, pixel count, and duration time.
The Freeze detection system can be set to detect a clean or noisy source. Freeze Time sets the number
of seconds for the 9455 or 7435 to switch to the secondary input after a video freeze condition is
detected in the primary input.
The switch can operate in two modes: automatic or nonresetting. In fully automatic mode, the module
will automatically switch back to the primary signal once it’s been restored. In the nonresetting mode,
the secondary input remains routed to the output, even after the primary input has recovered. In this
case manually switching back to the primary is required. If no valid input can be found, consistently
timed color black will be output.
Controls are easily accessed through an Avenue Control Panel, Avenue PC software, GPIs, or front edge
module controls. Software updates for the module are done through a web browser via Ethernet using
the Interface Adapter Cable that comes with the module. This cable provides an Ethernet connection
www.ensembledesigns.com
7435 and 9455 - page 5
Model 7435 and 9455 Clean and Quiet Protection Switches
for software upgrades and a 9-pin GPI/GPO connector for control. GPI inputs allow faults detected in
upstream equipment to contribute to the switching logic.
Avenue module parameters can be congured 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 dierent slot in the frame at your discretion without losing the
stored information.
SDI Signal Evaluation
The 9455/7435 monitors the integrity of the serial digital input stream and analyzes its audio and
video content. HD SDI signal health and fault detection is determined by monitoring any or all of the
following parameters, in order of increasing complexity:
• Timing Reference Signal (TRS) – This parameter checks for the persistent loss of digital sync
by looking for the correct Timing Reference Signal carried in the serial video stream. When this
digital sync format is correct, the signal is considered good.
• Black – Black detection is based on three congurable parameters: black level threshold, black
pixel count, and black duration time. All of these parameters can be set using the menu system
to meet the needs of specic video signal inputs.
• Embedded Audio – This parameter will look for correctly congured embedded audio packets
in the horizontal intervals of the signals. The actual audio content of the packets is further
analyzed to detect silence. Specic audio parameters, such as audio group, silence threshold
level, and audio silence duration can be congured in the Avenue PC and Touch Screen
menus.
• Freeze – This parameter checks for a freeze condition as determined by the settings selected
in the Freeze menu.
A sophisticated black detection system is employed to activate the switch in the event that the signal
is lost. It allows the user to select not only the threshold and percentage of black pixels, but also the
portion of the picture to be considered. The area of the picture checked is determined by selecting
Small Window which is approximately two thirds of the picture width and height, or Big Window
which covers approximately 90% of the width and height. This allows a corner Bug to be either
excluded or included in the detection process.
Black detection is performed on a pixel-by-pixel basis within the selected window, with user selectable
Detect Level and Blk Frac adjustments. Pixels above the Detect Level are considered to be non-black.
Blk Frac sets the percentage of pixels which must be black in order to trigger an error. For example, if
Detect Level is set to 12 IRE and Blk Frac is set to 90%, and Blk Time is set to 3 seconds, then if more
than 90% of the pixels in each frame are below the selected 12 IRE level for a period of 3 seconds, a
switch will occur.
Pri Valid and Sec Valid are dynamic values based on incoming video. In the above example, if Pri
Valid fell below Blk Frac continuously for 3 seconds there would be a switch, provided that there
is valid secondary video. Note however, that the display may not keep pace with short duration
transitions of actual video. In the example, an excursion above 12 IRE for a single frame every 2
seconds would not cause a switch to take place, since the 3 second count would be reinitialized by
these valid frames.

The block diagram, above and on the following page, illustrates the signal ow of the 9455. Note that
in the event of power failure, the passive relay passes the primary input to the Relay Protected Output.
The Primary and Secondary inputs pass through serial digital receiver/equalizers for buering. When
a fault is detected in the Primary input, and the Secondary input is seen as not faulted, the electronic
solid state switch will activate, switching the Secondary input to the output. If both the primary and
the secondary inputs signals are faulted, consistently timed color black will be output.
Each of the signals is fed to identical detection circuits which evaluate multiple parameters
and characteristics of the signal in order to arrive at a fault decision. The output feeds a Field
Programmable Gate Array (FPGA) where the signals are vetted, or tested for congured parameters.
The Signal Vetter™ process in the FPGA detects the parameters chosen by the user through the
Avenue PC or Touch Screen menus. Each of the chosen aspects are monitored independently, and
when they fail to meet the vetted standard, a fault condition is issued.
Fault conditions can be monitored with an external alarm system or other device through the 9-pin
Control connector of the dongle connected to the corresponding 15-pin rear backplane connector.
The Form C relays status outputs from this connector can be monitored by a device to show Primary
and Secondary signal status and the current position of the protect switch (Primary or Secondary).
Two GPI Override Inputs are available to allow changing switch position in response to triggers from
an external source. This can be used to manually reset the switch after the Primary has recovered from
a fault condition or set to respond to a signal state from an external device to trigger a switch.
The on-board CPU can monitor and report module ID information (slot location, software version
and board revision), and power status to the 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.
Every function and parameter on the module can be controlled from an Avenue Touch Screen Control
Panel or the Avenue PC Control Application. Memory registers can be used to save the complete
conguration of the module, making it easy to change instantly between dierent congurations.

• Pri – lights green when the Primary input is selected to the output. Click this control to select
the Primary as the output.
• Auto – lights green when Auto is turned on. Switch Auto on and o with this control. When
Auto is on, the module will automatically switch to the Secondary input if the Primary fails and
the Secondary is good.
Note: If the module cannot nd a good signal on the Primary or the Secondary, it will output
consistently timed black. In this situation, both the Primary and Secondary buttons will be
grey and the Switch Position window will report Int Blk. The most likely cause of this is an
incorrectly set Output Format. The Output Format is set in the Output Menu and must match
the format of the Primary and Secondary inputs. The Input Formats are auto detected and
show in the Primary and Secondary Input report windows in the Input Menu.
• Sec – lights red when the Secondary input is selected to the output. Click this control to select
the Secondary as the output.
• Auto Reset – set to On or O to determine if the switch will automatically switch back to the
Primary after it recovers.
• Reset Time – set the amount of time the Primary signal must be good before the Auto Reset
switches back to Primary from Secondary.
