7765MVM MultiViewer Monitoring
1. OVERVIEW
Optimized for multiple video signal monitoring, Evertz’s 7765MVM MultiViewer Monitoring product line
simultaneously extends audio, video and data signal integrity monitoring (as per Evertz’s AVM product
line) capabilities up to 8, 12 and 16 video input channels – optimized to fit 16:9 or 4:3 displays. 7765MVM
modules conveniently fit into Evertz’s 7700FR-C frame, and offer a high-resolution and cost-effective
monitor-wall solution for multi-channel broadcast transmission facilities.
The 7765MVM modules come equipped with 7700FC VistaLINK™ Frame Controllers and are VistaLINK™
ready, offering remote monitoring, control and configuration capabilities via Simple Network Management
Protocol (SNMP). The 7700FC VistaLINK™ Frame Controller card provides a single point of access to
communicate with VistaLINK™-enabled 7700 series of cards. The 7700FC provides a 10Base-T/100Base-
TX Ethernet port and communication is facilitated through the use of Simple Network Management
Protocol (SNMP). The 7700FC handles all SNMP communications between the frame (7700FR-C) and the
network manager (NMS), and serves as a gateway to individual cards in the frame. This product feature
offers another solution to manage operations including signal monitoring and module configuration from
SNMP-enabled control systems (Manager or NMS) locally or remotely.

• External AES audio (MVM-xA versions only) and GPI I/Os are available on DB-25 connectors with
optional Bulkhead Breakout Panels
• RS-232 or RS-422 serial port (jumper configurable) for interface to external equipment via
communication protocols
• System configuration and channel monitoring through VistaLINK™ with 3RU 7700FR-C frame and a
7700FC VistaLINK™ Frame Controller module
1.1. FUNCTIONAL DESCRIPTION
For each of the four SDI(601) inputs, serial digital video is converted to parallel and embedded audio,
VITC, closed captioning and source ID are extracted from it. The audio is read by the CPU and further
processed to extract level information. The CPU creates the level and phase bar graphs and writes them
out to the on screen display (OSD) memory. The hardware mixes (keys) the on screen text and bar graphs
display information onto the video stream. This video goes out digitally through a parallel to serial
converter and/or analog through a composite encoder.
Revision 1v0_3a 7765MVM-1

7700 MultiFrame Manual
7765MVM MultiViewer Monitoring
The CPU also gets push-button and toggle-switch commands from the card edge controls and draws
extensive menus for configuring the operation of the card. Card configuration is also possible through
VistaLINK™.
Figure 1: 7765MVM-16/-16A System Block Diagram
2. INSTALLATION
The modules of PKG7765MVM-x come with a companion rear plate that includes BNC connectors, a high-
density DB-15 and several female DB-25 connectors. PKG7765MVM packages occupy up to 11 slots in
the 7700FR-C frame. For information on mounting the rear plate and inserting the module into the frame
see the 7700FR-C chapter, section 3.
2.1. VIDEO IN AND OUT
Connect a source of component digital 525 line or 625 line 270 Mb/s (with or without embedded audio, or
external AES/EBU) video to each (or any) of the four SDI inputs (labeled “SDI INPUT 1-4”). Subsequently,
connect the “Video Output” BNC to the “Video Input” BNC. These should be connected in the order that
they are numbered.
In some cases, one rear plate spanning the total number of input and output BNC is replaced by separate,
dual slot rear plates per module. As in the above case, connect the serial video output BNC on the
7765AVM-4-SD (7765AVM-4-M) or 7765AVM-4A-SD (7765AVM-4A-M) modules to the input BNC on the
7765AVM-4-VGA (7765-Q) rear plate. For additional information on the Quattro rear plates, refer to the
Quattro (7765AVM-x or 7766AVM-x) manual.

2.2. GENERAL PURPOSE INPUTS AND OUTPUTS
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 3 shows the input circuit for the
General Purpose inputs.

2.2.1. RS-232/422 Serial Port Connections
The COM port signals are either standard RS-422 or RS-232 with no hardware flow control. The
directions of the signals are indicated in Table 1. The port on the AUDIO AND AUX I/O connector is
used for data logging of the status and fault condition alerts. Jumper J21 located on the 7765AVM-4
module is used to determine whether the designated pins operate as a balanced RS422 Receive and
Transmit channel, or as a RS-232 Receive and Transmit channel. (See Figure 7.)
Revision 1v0_3a 7765MVM-5

5. STATUS LEDs
5.1. MODULE STATUS LEDs
MODULE STATUS: This Green LED will be on each module (7765Q and 7765AVM-4-M/7765AVM-
4A-M) when the module is operating properly.
LOCAL FAULT: This Red LED makes it easy to identify one module in a frame that is missing an
essential input or has another fault.
The Red LED will blink on and off if the microprocessor is not running.
The Red LED will be on when there is a fault in the module power supply or a
user configurable error condition exists (as configured through the Frame Status
Trigger menu option).
5.2. VIDEO STATUS LEDs
Four LEDs on the top board ((B)7700CC) of each MultiViewer module indicate which video input signals
are present.

6. OPERATING LEVELS, HEADROOM, CLIPPING AND THE BAR GRAPHS
This section contains notes to understand how the AVM product line relates digital audio levels, analog
output audio levels, and the displayed bar graph levels.
When a full-scale digital signal is input, you will get an analog output signal level that is set by the Peak
Output Level. The Headroom control sets the 100% program reference level (0 dB on the scale) with
respect to the Peak Output Level. For example, if the Peak Output Level is set to 24 dBu and the
Headroom is set to 20 dB, then the 0 dB reference on the bar graphs will correspond to an output level of
4 dBu. This level will be achieved when a digital input signal of –20 dB FS is applied at the input.
Therefore, the following relationship is always maintained:
PGM reference level + headroom = peak output level
NOTE: The VU and PPM standards were set before the digital revolution. These standards deal with
headroom levels that are quite a bit lower what should be used in the digital world. Also, most of the
bar graphs only display a few dB above the program reference level. In a digital world, one needs to leave
around 20 dB of headroom to keep most material away from clipping.
For best results, follow these steps when setting up the audio bar graphs and output levels:
1. Set the Headroom control to the desired value. Remember that this is the value in dB between the
100% reference level (expressed in dB FS) and saturation level of the digital input word (0 dB FS). It
will also correspond to the value in dB between the analog output level when a reference level is input
and the maximum output level set by Peak Output Level.
2. Pick the bar graph type and mode. This selection will configure the bar graphs with the defaults
dictated by the standards. It will also set the Peak Output Level and the 0dB reference level to adhere
to the standard and the desired headroom.
3. Adjust any of the bar graph configuration parameters to customize the display of the graphs.
4. Save the card configuration into a preset so that you can recall it if any card parameter is tampered
with.

7. AUDIO ALARM CALIBRATION PROCEDURE
This section contains detailed description on setting the various audio warning/error detection parameters.
Some of the audio alarm detection algorithms are dependent on the state of other audio alarm detectors.
For instance, the mono detection algorithm will not use periods of silence as determined by the silence
detection. For this reason, the following sequence should be used to calibrate the audio alarms. The
items in Italics refer to menu items in the AVM. See section 7.5 for a complete description of the fault
definition menu items.
7.1. CALIBRATE AUDIO SILENCE DETECTION
1. Supply the card with your plant's noisiest audio feed without any audio program material present. This
will be a baseline noise level to calibrate the silence detector.
2. Turn off all sources of errors in a Fault Condition and assign Audio Silence as the only error. Also,
make sure that you set the Fault Duration to a small number of frames so that you will see when the
error condition disappears.
3. Set the Silence Duration to 0.5 sec so that you can see the results of adjusting the Silence Level
parameter without getting confused with the detection time.
4. Adjust the audio Silence Level until the Fault Condition begins to go active. This will be the noise floor
level. Raise the Silence Level a few dB to make the detector insensitive to this noise level.
5. Set the Silence Duration to a time appropriate to your application. This should be set to a value longer
than your worst case acceptable quiet period.
7.2. CALIBRATE AUDIO PHASE REVERSAL DETECTION
1. Supply the card with a stereo signal that has the phases reversed. Make sure that the material is
typical of normal content for this channel.
2. Turn off all sources of errors in a Fault Condition and assign Phase Reversal as the only error. Also,
make sure that you set the Fault Duration to a small number of frames so that you will see when the
error condition disappears.
3. Set the Phase Reversal Duration to 0.5 sec so that you can see the results of adjusting the Phase
Reversal Level without getting confused with the detection time.
4. Adjust the Phase Reversal Level so that the Fault Condition detects the phase reversal.
5. Set the Phase Reversal Duration to a time period appropriate to your application.
Warning: Periods of silence (below the Silence Level) will extend this duration. In other words, periods
without audio content are not included in the phase reversal detection.
Warning: Stereo material with long periods of dissimilar left/right content (i.e. music with plenty of
panning) may cause the phase reversal detector to fire. It is best to set the Phase Reversal Duration to
a value larger than what you would expect.
