audio metering and monitoring capabilities are also incorporated.
MV-32/MV-64 multiviewers are designed to optimize monitoring flexibility within the
multi-channel video environment, including video production, television broadcast, CCTV,
medical, aerospace, exhibition and conference applications. It is supplied in either single or
dual multiviewer configurations as a 3U rack mounting frame. The MV-32/MV-64 can be
connected to an optional external backup power supply (MV-Power). The MV-32/MV-64
multiviewers are easily controlled from a PC web browser hosted by the frame itself, either
directly via an Ethernet cable or over a network.
The MV-32/MV-64 multiviewers are can also be used as a multi-channel audio matrix,
de-embedder and analog to AES/EBU digital cross converter, depending on the I/O cards
fitted.
Various combinations of video/audio inputs can be configured. The maximum number of
audio outputs is 64 channels (using 2 x output boards). Any input may be routed to single or
multiple outputs.
2.1 System concept
The modular architecture is designed for scalability. Of the two 3U frame types available, the
single multiviewer frame (MV-64), is equipped with one controller (CPU), one Buffer card and
one power supply module (PSU). The dual multiviewer frame (MV-32) is centrally divided and
capable of housing two separate multiviewers, each with its own CPU and Buffer card. The
Buffer card generates the 5 Volt power and distributes it to the rear cards. The card also
buffers signals generated on the CPU (such as clocks, data and I2C) and distributes them to
the VIP cards and rears.
Each video input card handles 4 sources. The single MV-64 frame will accommodate up to 16
video cards, providing a maximum capacity of 64 video channels. The dual MV-32 frame
provides a maximum capacity of 32 video channels for each multiviewer (8 video cards per
side). The video cards include support for SDI embedded audio. If external audio interfacing
is required, audio input or output cards may be fitted. These will reduce the capacity available
for video cards in the MV-32 but the MV-64 has two dedicated audio slots in addition to
16 video/audio slots. A maximum of eight audio cards (any mix of input and output) can be
fitted in an MV-64 multiviewer.
The video input cards will simultaneously support sources of differing rate, for example, 50Hz
and 60Hz. However, synchronisation is achieved by frame add and drop rather than
standards conversion. The system rate is either locked to the reference signal provided or a
designated video input source.

A scaler on each video card processes one of the possible input sources and scales it to the
desired tile size for the selected position on the display output. A mixer on each video card
combines all the video tiles and sends the resulting image to the next video card. The final
display output comprises all of the tiles in a single picture.
2.1.1 Video Input Card types
Possible video inputs are shown below. For details of card and Multiviewer firmware
compatibility see Table 1. on page 11.
•Card Type MV-VIP3 - Composite (limited to 2 inputs per card, inputs 1 and 2),
SD-SDI, HD-SDI 3 Gb/s (Level A) & 1.5 Gb/s (up to 4 inputs per card)
•Card Type MV-VIP3D - Composite (limited to 2 inputs per card, inputs 1 and 2),
SD-SDI, HD-SDI 3 Gb/s (Level A) & 1.5 Gb/s, including Dolby E level metering (up to
4 inputs per card)
•Card Type MV-VIP1 - (no longer supplied) - Composite, S-video, RGB, YUV, SD-SDI,
DVI-I
•Card Type MV-VIP2 - (no longer supplied) - Composite, S-video, RGB, YUV, SD-SDI,
HD-SDI 3 Gb/s (Level A) & 1.5 Gb/s, DVI-I
Overlay of audio and graphics information is performed inside each scaler, which receives
control data from the main CPU in real-time for external audio sources, or from the video card
itself in the case of embedded SDI/HD-SDI audio.
To allow arbitrary layering of sources, each input board has information about all of the tile
positions, allowing each tile to be displayed as required and enabling picture overlay with
complex borders.
Fig 1. The MV-32/MV-64 System Concept.
Note:
• The MV-VIP1 and MV-VIP2 cards were supplied with earlier multiviewers and are
shown in this manual for users that already have them fitted.
• The MV-VIP3 and MV-VIP3D cards cannot be mixed with MV-VIP1 or MV-VIP2
cards in the multiviewer frame because they use different versions of firmware.
If MV-VIP3 or 3D cards are to be fitted in a multiviewer frame that contains
MV-VIP1 or MV-VIP2 cards they must first be removed and replaced with MV-VIP3
or 3D cards.

2.2.1 Powerful alarms
Alarms may be created for video sync loss, black (loss of luminance), freeze-frame,
embedded audio loss, external audio loss, over level, out of phase (of chosen pairs), teletext
loss, and closed caption loss. Audio alarms can be configured to be displayed above the
audio bars and/or in text boxes.
The colors used for on-screen alarms located above the audio bars are as follows:
• Audio Loss: Yellow - position (left or right) indicates channel
• Audio Over: Red - position (left or right) indicates channel
• Anti-Phase: Cyan - middle alarm
• Carrier Loss: White - middle alarm
If carrier loss occurs, only that alarm will flash, unless audio loss had already been active for
the same channel.
Alarms are also available for WST, OP-47 and closed caption loss.
On screen alarm indication may be a stationary or flashing colored tile border. External alarm
indication may be via the GPI I/O or the LAN/software application.
Optional triggering of SNMP traps for each alarm function or group is also supported.
Tiles have an optional color coded border to provide status indication, such as tally or alarms.
VITC loss is indicated by the burnt in VITC display flashing. Burnt in VITC is available from
SDI sources only.
2.2.2 Captions and UMDs
Captions or Under Monitor Display (UMD) information may be generated manually from a
keyboard connected to a front panel USB-2 port or automatically from remote sources via the
LAN, using browser software operating on a remote PC, or via the RS232/422 port using TSL
or other protocols. Up to two lines of UMD text can be left, centre, or right justified and may be
placed anywhere in the tile.
2.2.3 Using bitmaps
There is storage capacity (approximately 200MB) for bitmaps. These can be used as
backgrounds, or to display station idents, etc. The bitmaps must be in bmp or png file format
and can be uploaded to the frame via the LAN. Up to four bitmaps may be displayed at any
one time.
2.2.4 Keeping time
Clock/date display data can be derived from several sources; the system clock, NTP
synchronisation, LTC, or VITC from a chosen SDI input.
If there is no LTC present, the frame searches the network for an NTP Server in the nearby
region (pool.ntp.org). If a server is found, the time is taken from that.
In the absence of any clock, the system time is used. A battery on the CPU board insures that
time data is retained if the unit be powered down.
Note:
When LTC is present this source becomes the exclusive reference for clocks.
The input is balanced; to use an unbalanced LTC input, the signal must be properly
converted with a Balun in-line transformer. Grounding either of the LTC input pins will not
work.

MV-32/64 Multiviewer www.snellgroup.com Introduction
Issue 1 Rev 11 Page 14 © 2014 Snell Limited
For each input is possible to display either the Ancillary Timecode or the DVITC from the
video source.
LTC is applied to the frame through a BNC on at the rear of the frame.
See section 4.5 for more information.
If VBI data is present on a video input and the video is an SDI source then the data can be
displayed on the relevant video tile (see sections 4.16.5.6 and 4.16.5.7 for setting details).
If multiple sources of timecode are present in a video source then the timecode selected for
display, in order of priority is; Ancillary VITC, Ancillary LTC and D-VITC.
2.2.5 Genlocking
Genlocking of the MV-32/MV-64 multiviewer is via SD color black or HD tri-level sync, using
the genlock input.
2.2.6 Using GPI I/O
Assignable GPI I/O with 16 inputs and 8 outputs for external alarm indication and tally
functions.
2.2.7 Bargraph scales
The following audio scales are supported:
Colors used for the upper and lower ranges of each bar type can be customized to satisfy any
in-house monitoring style for each of the six scale types.
For the MV-VIP3D cards the meters can be configured appropriately to display the levels of all
channels in a Dolby E stream (embedded audio only, not audio from external audio input
cards).
Note:
1. D-VITC is only available on SD sources as there is currently no standard for HD
sources. Ancillary Timecode is available on both SD and HD sources.
2. The Timecode is displayed in a fixed position near the bottom center of the tile
within the video.
3. The display will start to be cropped when the tile is 150 pixels or less wide.
Fig 2. Available Meter Scales.

The CPU card, Buffer card and PSU module are located in fixed positions within both the
single (MV-64) and dual (MV-32) multiviewer frames. A CPU card will always be fitted to slot 1
and a buffer card in slot 2. A dual frame MV-32 multiviewer will additionally have a CPU card
fitted in slot 11 and a buffer card in slot 12.
Video and audio cards are installed in the remaining slots in sequence, from right to left, as
viewed from the front.
3.4.1 Video Inputs
Separate rear connector modules of the required type are fitted to allow interfacing with each
input card. These are available with different combinations of BNC and Microcross DVI-I
connectors to suit the application. A single BNC connector is used for formats such as
SD-SDI, HD-SDI and *Composite video. For S-Video, two BNC connectors are required, for
RGB/YUV three BNC connectors are required.
Most video input card connector modules are also equipped with an 8 x GPI port, although in
some instances, insufficient space is available.
3.4.2 Video Outputs
The two DVI-I display outputs (per multiviewer) support resolutions up to HD 1080p60, 16:9
(1920 x 1080). Both digital and analog outputs are available on these connectors. Tiles
displayed via the outputs can be varied continuously in size and position, cropped or
displayed in pre-configured screen layouts on a chosen colored background. The pair of
outputs may either be set to provide two identical display configurations, or they may have
differing arrangements.
3.4.3 Audio I/O
Audio levels may be displayed using up to 16 bargraphs in each tile (32 bargraphs per tile
with MV-VIP3D cards), either superimposed on each video image or outside active video.
Audio is derived from the incoming embedded audio (when using SD-SDI or HD-SDI inputs),
or from external sources, for which the appropriate audio input card option must be installed.
Optional audio output cards (32 channels analog or 16 AES/EBU pairs) may be fitted to
provide demuxed outputs from embedded audio.
Audio input and output cards must be fitted in conjunction with the appropriate rear connector
modules.
There is an 8 channel analog audio monitor output, which may be assigned from any input
channel of any format, excluding incoming external audio level data.
All bargraph scales and ballistics conform to international standards and include BBC PPM,
DIN PPM, Nordic PPM, VU, extended VU, and AES/EBU digital.
Note:
The I/O cards are not hot-swappable and the multiviewer must be powered down when
inserting and removing cards.
Note:
• Component and DVI inputs are not supported by the MV-VIP3 and MV-VIP3D
cards.
• *Only inputs 1 and 2 can be used for Composite video on MV-VIP3 and MV-VIP3D
cards.
Note:
The number of audio channels described always refers to individual channels, not channel
pairs. For example, eight monitor outputs relate to eight individual analog channels or 4
pairs AES/EBU channels.
