MV-16 Multiviewer www.snellgroup.com Introduction
Issue 1 Rev 12 Page 7 © 2013 Snell Limited
1. Introduction
The compact MV-16 multi-viewer enables up to 16 channels of video to be viewed on a single
display device. The inputs are auto-sensing composite, SDI, HD-SDI inputs. In addition there
are two DVI-I video inputs. Up to 3G 1080p is supported.
The MV-16 is designed to optimize monitoring flexibility within the multi-channel video
environment, whether used for video production, television broadcast or CCTV. It is supplied
as a 1U rack mounting frame. It is easily controlled from a PC web browser hosted by the
frame itself, either directly via an Ethernet cable or over a network.
1.1 System Concept
The modular architecture is designed for scalability. Each video input card handles four
channels. Up to four cards may be fitted to the frame, providing a total of 16 inputs.
Additionally, if external audio functionality is required, audio input or output cards may be
fitted. The diagram below shows the overall concept.
A scaler on each video card processes one of the possible inputs (CVBS, SDI/HD-SDI, DVI)
and scales it to the desired tile size for the selected position on the 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.

Fig 2. The MV-16 System Concept.

MV-16 Multiviewer www.snellgroup.com Introduction

Possible inputs are:
• Card MV-VIP1 - Composite, S-video, RGB, YUV, SDI, DVI-I
• Card MV-VIP2 - Composite, S-video, RGB, YUV, SDI, HD-SDI, 3G-SDI, 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 analog/AES/EBU/ channels, 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.
DVI-I inputs replace inputs on BNC 1 and 2. If DVI-I input 1 is enabled, any SDI input on
BNC 1 is replaced by the DVI-I input. Similarly, DVD-I input 2 will replace any SDI input on
BNC 2.
1.2 Features and Benefits
• Up to 16 auto-sensing monitored composite, SDI, HD-SDI S-Video, RGB and YUV
inputs and two DVI-I video inputs (up to 3G 1080p)
• DVI-I output up to 1080p60 (1920x1080) in 16:9
• Genlocked inputs for flicker-free and full frame operation
• Teletext (analog), subtitles, AFD, WSS, VITC (SDI/HD-SDI only) decoding &
monitoring
• Up to 256 channels of embedded audio may be displayed as industry standard
bar-graphs with a choice of scales/ballistics
• Using the appropriate optional input card up to 32 external analog or digital audio
channels (AES/EBU with SRC) can be displayed
• 4 pairs of assignable analog audio monitor outputs
• Outputs for up to 32 channels of demuxed audio; analog or AES/EBU
• Alarms for video, audio and metadata, with outputs to GPI outputs, LAN and/or SNMP
traps
• Assignable tallies
• Under Monitor Displays (UMD) entered via keyboard, LAN or serial cable, supporting
TSL and other protocols
• Clock display receiving time information via NTP network protocol or LTC
• 1 RU compact design, ideal for OB-vans and other space restricted installations
• Front panel control
• User-friendly set-up via system menu/browser software
• Standard internal dual redundant power supply fed from a single IEC input
Note:
If composite inputs are used on BNC 1 and 2, they may be routed inside the first video card
to channels 3 and/or 4.

1.2.1 Powerful Alarms
Alarms can 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. The colors used for on-screen alarms are as follows:
If carrier loss occurs, only that alarm will flash, unless audio loss had already been active for
the same channel.
The decoding of closed caption is available on each scaler, together with an associated
alarm. Analog teletext decoding is available in the scaler.
On-screen alarm indication can be a stationary or flashing colored tile border. External alarm
indication may be via the GPI I/O or the LAN/software application, e.g. NGM-164.
Optional triggering of SNMP traps for each alarm function or group are 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.
1.2.2 Captions and UMD
Captions or Under Monitor Display (UMD) information can 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, center, or right justified and may be
placed anywhere in the tile.
1.2.3 Using Bitmaps
There is storage capacity (about 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.
1.2.4 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.
For each input is possible to display either the Ancillary Timecode or the DVITC from the
video source.
Alarm Color Position
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
Table 1. Alarms.
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.

LTC is applied to the frame through a BNC on the rear of the frame.
See section 3.6 for more information.
If VBI data is present on a video input and the video is an SDI source then the data can be

2.3 Connector I/O
The MV-16 uses coaxial BNCs for the video inputs, LTC and sync inputs. Micro cross
connectors are fitted for the two DVI-I inputs and one output. The GPI I/O connector is a high
density 26 way female 'D' connector. External audio connections (input or output) are via a
pair of female 37 way 'D' connectors, with audio monitoring outputs on a male 25 way 'D'
connector. The serial port comprises a 9 way female 'D' connector. A standard RJ45
connector is provided for LAN connection and a USB connector on the front panel is provided
for connecting a keyboard. (A pack of mating 'D' type connectors is supplied with the unit).
2.4 Input card configurations
The MV-16 may be fitted with up to four MV-VIP1 or MV-VIP2 video input cards, or any
combination of the two types. Additionally, an external analogue or digital audio I/O card may
be fitted to a dedicated card slot as an option.
MV-VIP1 video cards support the following standards:
• Composite video PAL/NTSC, CVBS - 1Vpp
• SDI - SMPTE 259M
• DVI-I - digital or analogue component, 1920 x 1080
• S-Video (Y/C)
• Component video RGB/YUV
The MV-VIP2 video card supports HD-SDI up to SMPTE 292M 3G, in addition to the
standards supported by the MV-VIP1 card.
The controller card is always fitted in the top left slot and the Analogue/Digital audio card is
always fitted in the bottom left slot. Video input cards are installed in the remaining slots as
shown Fig 7.
Fig 5. MV-16 1U frame rear connector Input/Output.

Issue 1 Rev 12 Page 13 © 2013 Snell Limited
2.4.1 Video Inputs
All inputs (except DVI-I) are assigned to the 16 x BNC input connectors at the rear of the unit.
Up to 16 inputs can be applied if the configured video format uses a single BNC (SDI,
HD-SDI, composite). For S-Video, two connectors are required, for RGB/YUV three
connectors are required.
There are two DVI-I input connectors, as this is the maximum number of DVI-I inputs
supported per frame. All input types are assigned within the unit's system menu.
Component inputs such as YUV or RGB require three connections per channel and only one
channel can be handled per input card. However, a further two channels can be fed via the
analogue pins of the two DVI input connectors (and suitably assigned in the unit's menu)
making a maximum total of six channels. Any unused BNCs can be used for other video
formats.
For Y/C, two connections per channel are required. Therefore two channels can be handled
per input card, giving eight channels per frame. Any unused BNCs can be used for other
video formats.
2.4.2 Video Outputs
The main DVI-I output supports resolutions up to HD 1080p60, 16:9 (1920 x 1080). Both
digital and analogue outputs are available on this connector. Images on the output screen can
be varied continuously in size and position, cropped or displayed in pre-configured screen
layouts on a chosen colored background.
The main output is also used to display the unit's system menu when screen configuration
and set-up options are selected. This is not necessary when using external control via the
LAN.
2.4.3 Audio I/O
Audio levels may be displayed using up to 16 bargraphs in each tile, either superimposed on
each video image or outside active video. Audio is derived from the incoming embedded
audio (when using SDI or HDSDI inputs), or from up to 32 channels from external analogue or
AES/EBU sources, for which the appropriate audio input card option must be installed.
Additionally, external audio may be monitored using level data from the Snell NGM-164 via
the LAN.
Note:
1. When external inputs are not required, an optional output card (32 channels
analogue or 16 AES/EBU pairs) may be employed to provide demuxed outputs
from embedded audio.
2. There is an 8 channel analogue audio monitor output, which may be assigned from
any input channel of any format, excluding incoming external audio level data.
3. The number of audio channels described always refers to individual channels, not
channel pairs. For example, eight monitor outputs relate to eight individual
analogue channels or 4 pairs AES/EBU channels.
4. All bargraph scales and ballistics conform to international standards and include
BBC PPM, DIN PPM, Nordic PPM, VU, extended VU, and AES/EBU digital.
