Introduction
360 Systems’ MAXX Image Server™ is a multi-channel video recorder/server designed for
television broadcast and production applications. It can play three independent video streams at
once, and store up to 170 hours of MPEG-2 video, with four audio channels per video stream. It
occupies just 3½” of rack space. The server’s extensive feature set makes it an excellent choice for
VTR replacement, broadcast automation, remote trucks; production for PEG, corporate and houseof-worship video; and live entertainment presentations. Image Server MAXX is produced in
separate NTSC and PAL models. References in this document to frame counts other than 29.97 or
30 frames should be understood as a PAL example.
The Transition to a Digital Plant
Image Server MAXX smoothes the transition to digital production and broadcasting by
providing both composite video and serial digital (SDI) interfaces, plus program file transfers over
Gigabit Ethernet. It’s never necessary to add outboard video A/D or D/A converters or MPEG
encoders; premium-quality codecs are included as standard equipment. The server’s dual analog
and digital personality—for both video and audio—makes it fit seamlessly into an existing analog
facility, or become part of a new digital build-out. Apart from serving its intended purposes, Image
Server MAXX is also valuable for its ability to convert between different analog and digital media
formats in real-time.
Exceptional Storage Capacity
The Image Server’s program storage is scaleable to suit the needs of both small and large
users. It houses four hard drives within its compact enclosure, providing either 112 or 170 hours
of storage at 12 Mb/sec. Storage time is proportional at other data rates. The server’s RAID-5 disk
array provides a high level of security for stored programs. By spreading parity information across
all drives, the RAID array helps keep the server in service—even with a failed drive. The multidrive storage array also generates the high data rates needed for multiple video streams at up to 50
Mb/sec, and enables fast program transfers through the Gigabit Ethernet port.
Drive Size
250 GB 1.0 TB 112 hours 150 hours
400 GB 1.6 TB 170 hours 250 hours
The Image Server’s unique ability to play two video streams while recording a third, and at
the same time do file transfers over Gigabit Ethernet, make it far more than just a VTR replacement.

Image Servers Support Traditional VTR Functions
The Image Server is a perfect drop-in replacement for popular VTRs. It saves costs for tape,
machine maintenance, cassette prep, and storage. Its three output channels perform any
8 Introduction
combination of tasks, including responding to GUI or automation commands, clip trimming or
browsing.
Unlike a VTR, the Image Server can simultaneously record and play a program. A new
recording can start at any time, even when two simultaneous playbacks are in progress. As a VTR
replacement, the Image Server is controlled through a 9-pin serial interface. Several serial
protocols are supported, allowing the Image Server to immediately operate with the controllers you
already own. VDCP and Odetics protocols provide very complete server control, including editing
functions. Sony BVW protocol is also provided in an abbreviated form allowing basic machine
control, without insert-editing. Six parallel “GPI” control channels are also provided.
Compatibility with Automation Controllers
Image Servers work with automation controllers from many different manufacturers. They
use established VDCP and Odetics protocols allowing 9-pin control of each server channel, for
maximum flexibility. 360 Systems’ automation partners provide controllers for applications
ranging from affordable systems for Pro-AV, up to large-scale broadcast solutions. Contact a 360
Systems application engineer, or an automation provider for assistance with your requirements.
Remote Controls
Hardware accessories are available from third-party manufacturers to perform transport
control, trimming, clip replay and playlisting (automation). A table of approved controllers is
provided elsewhere in this manual. Contact 360 Systems Sales Support team for assistance with a
specific application.
The Image Server provides six GPI inputs for remote play, stop, and record capability from
push-button panels or other GPI-controlled equipment. Six outputs are also provided; these may
be used for command acknowledgement (to drive LEDs or logic inputs), or may output commands
embedded within an Advanced Playlist on the Image Server.
Extended Feature Set
Image Server MAXX encodes video in MPEG-2 format, in 4:2:2 Profile with data rates to 50
Mb/sec, or in Main Profile to 15 Mb/sec. Both I-frame and long-GOP formats are supported.
MPEG-2 file transfers in MXF-format are compatible with servers from other market leaders, and as
IMX (D-10) files compatible with Sony EVTRs.
The DV and Graphics capability allows Direct Digital Import™ of DV-25 and TARGA files
to an Image Server over an Ethernet connection. DV files may then be trimmed, playlisted, stored,
played out, and re-exported over Ethernet. They remain in DV format at all times, and are not
converted to MPEG. TARGA files may be imported to the Image Server, and will be converted into
separate high-resolution MPEG-2 “key” and “fill” files. These can be played as a synchronized
pair, for downstream compositing.
Introduction 9
Audio Features
Image Servers include both analog and digital audio circuits, making it an easy fit when
upgrading a facility. Gold XLR connectors are used for audio inputs and outputs. Each output can
be configured for either AES/EBU digital or +4 dBu balanced analog. In discrete digital format,
each video program can have four channels of audio, whereas analog I/O provides two channels.
(An AES/EBU line on a single XLR connector carries two audio channels, so a given number of XLR
connectors make more channels possible in digital format). SDI embedded audio is also included
as standard equipment.
360 Systems brings extensive experience in broadcast and pro-audio to the design of Image
Servers. They employ a 24-bit word, and deliver a 20 dB improvement in SNR (10 times!)
compared with older 16-bit audio systems. A sample-rate converter is included in the audio input,
which may be inserted from the GUI. Input circuits provide excellent hum and RF rejection, and
20 dB of headroom. 360 Systems’ Bit-for-Bit® design strategy assures that Dolby®-E, Dolby AC3, or
other forms of encoded audio will be stored and played correctly.
On-Screen Graphic User Interface
The Image Server’s On-Screen graphic user interface (GUI) gives fast access to all server
functions. It is controlled by a standard keyboard and mouse (supplied) and requires only a VESAcompliant SVGA display.
The GUI displays a complete control panel for each server channel; these include transport
control, clip file management and head and tail trimming. The GUI allows an Image Server to
operate as three self-contained VTR equivalents.
System configuration is clear and straightforward with the GUI. It provides access to
MPEG-2 encoding parameters, audio channel and time-code settings. Whenever new server
features are installed (using the built-in CD-ROM drive) new set-up parameters and user-interface
features become immediately available.
Remote Workstation Software allows the GUI to be remotely operated from a common
Windows® PC connected by Ethernet. Separate work areas can be easily created within a building
for ingest, trimming, playlisting, system monitoring or play-to-air.
File Transfers over Gigabit Ethernet
Image Servers go beyond providing just base-band connections for video and audio. Both
DV and MPEG-2 file transfers over Gigabit Ethernet open the door to new IP solutions for
transferring video across the room—or across the country—at high speed and low cost.
By adding economical ethernet switches and broadband connections, the Image Server’s
design enables low-cost networking of broadcast operations from ingest to storage, for editing,
play-to-air and archiving. The Image Server moves programs many times faster than real time,
saving time and streamlining operations.
360 Systems’ MXF implementation for MPEG-2 transfers uses Operational Patterns 1a and
1b. It has been tested for compatibility with MXF files from many other manufacturers. 360
Systems can make Image Server MXF files available for testing and evaluation through our FTP site.
Contact the customer service department to arrange for access.

Installation 15
Rack Mounting
Note: If you plan to use digital audio, be sure to change the configuration of the
Analog/Digital Audio Jumpers inside the unit before mounting the Image Server in a rack. The
jumpers are factory set to the Analog audio position. For more information about changing the
jumpers, see Analog/Digital Audio Selection on page 107.
There are four adhesive-backed rubber feet on the Image Server. These may need to be
removed when rack mounting the unit.
In North America, the Image Server will usually be mounted in a 19” rack enclosure having
10-24 or 10-32 tapped holes. In countries with metric standards, the user will need to supply
appropriate fasteners.
Cables attached to the rear of the Image Server should be supported by the rack mounting
rails. Do not support substantial cable weight from the Image Server.
Remove the front panel to expose the rack screw slots. Fasten the Image Server into the
rack using #10 flat-head Phillips screws (provided in North America). Replace the front panel.
Tighten the front panel access screws.

Important Installation Notes
System Cooling
When many pieces of equipment are mounted in an equipment rack, a considerable
amount of heat may be produced, which must be removed efficiently. Further, a lower operating
temperature will make equipment operate more reliably, and it will last longer. In the extreme
case, excessive temperatures cause rapid equipment failure, and damage which can be difficult to
repair.
Heat in an equipment rack should be removed by forced air. This is often accomplished by
blowers installed in the top of the rack, venting into the room. An alternative is to draw hot air
from the top of the rack into an air-conditioning return duct, and not vent it into the equipment
room; cold air should be ducted into the bottom of the rack.
The optimum air temperature for cooling electronic equipment is 25° C (72° F). When
many pieces of equipment are contributing to the heat load, a substantial air-flow will be needed,
and the inlet temperature may need to be lower.
Check These Points
• Are all ventilation holes in the Image Server free of obstruction?
• Can blowers or HVAC system adequately remove heat from the equipment rack?
• Have you measured the actual temperature
• Verify that the HVAC system is not
• What procedures are in place to protect the equipment when the HVAC system fails?

inside the rack? Do this near the top.

Important Installation Notes
Power Conditioning
It is good practice to operate an on-air video server from an Uninterruptible Power Source,
or UPS. All utility power systems experience occasional transient events, including brownouts and
dropouts, which are capable of taking a server off the air. It is the station operator’s job to plan for
and overcome such contingencies.
UPS units suitable for smoothing short-term power line problems come in two varieties:
Change-over UPS Design
This design senses drop-outs and low-line voltage, and switches its output to an internal
inverter operating from a battery. This UPS is low in cost, and is most often used in non-critical
applications such as desk-top computers. A disadvantage is that it may create its own power
transients when switching between utility power and its inverter supply.
Continuous Conversion UPS Design
This improved design continuously converts utility power to DC, stores it in a battery, then
produces isolated AC power from an inverter. It never switches, and is immune to input transients,
brownouts, and blackouts. Models are available with batteries of almost any size, making the
continuous-conversion UPS suitable for transient suppression or long-term operating power in the
absence of utility power.
Recommended UPS Models
The following makes of continuous conversion UPS systems are suitable for use with 360
Systems’ Image Server products:

Important Installation Notes
Operating Environment
A video server is the most critical element in a broadcast operation. Its installation should
safeguard it from every external event that can interfere with it doing the task expected of it. 360
Systems’ engineers have experience with thousands of installations, and have become aware of a
number of environmental factors that can adversely affect performance. Two of of these have
already been discussed: power conditioning and inadequate cooling. Two others, less obvious,
should also be considered:
RF Interference by Cel Phones
Many people are not aware that cel phones can attain a very substantial power output,
even when no conversation is taking place. You may have experienced the effect of a cel phone
interfering with a common desk phone placed nearby. Carrying a cel phone into a machine room
where it is in close proximity to broadcast equipment and its associated wiring is unwise. They are
able to interfere with serial control commands, video synchronization, and in some cases can crash
the CPU in equipment.
Some major broadcasters prohibit the carrying of cel phones into certain machine areas.
360 Systems believes that the risk of undesired equipment behavior from their RF fields is very real.
Static Discharge
Static electricity discharge is accepted by most people as an inevitable consequence of
living in a dry area. It is, rather, a result of floor coverings that may enhance appearances, but are
inappropriate for use around critical pieces of broadcast equipment. Static discharge can do two
adverse things:
• Discharge into a connector can—and will—destroy internal circuitry of equipment. The result
will always be difficult to diagnose and repair.
• Discharge to equipment frames or wiring can crash a CPU and take the station off the air. The
event may seem random or unrelated to static, but it is clearly a catastrophic event—and one
that can repeat indefinitely as humidity varies.
Several steps can be taken to protect equipment from static discharge:
• Do not install critical broadcast equipment (video servers) in a room with carpeting.
• Connect equipment racks directly to an earth ground with a heavy copper conductor.
• Do not operate equipment with a lifted safety ground (green frame ground).
• Install a humidifier to reduce the level of static discharge.

About Image Server Software
The Image Server is shipped with its application programs and operating system installed.
The first time that it is started, it must be connected to a keyboard, monitor and mouse.
The Image Server will ask you to accept the licensing agreement before it will operate. This screen
will only appear during the initial startup.
The CD-ROM drive is intended only for installing software. It may not be used to load
video or audio program content.
If for any reason it becomes necessary to reinstall any software, refer to the Maintenance
chapter for instructions.

Image Server Hardware Interface
Front Panel Features
Power ON/OFF button
The blue front panel button initiates start-up and shut-down of the Image Server. Press
it momentarily to start the server. A sequence of start-up screens will appear, ending with the
3-channel graphic user interface.
When the Image Server is running, pressing the blue button momentarily will cause the
system to begin an orderly shutdown. In the event that the system has stopped responding to
commands and will not shutdown, hold the button in for 4 seconds to force a power down.
Do not use the rear panel switch on the power supply to shut down the Image Server.
Abrupt power loss can cause loss of information stored on the disk array. The rear panel power
switch can be used to prevent re-application of power during service procedures once the
normal shut down sequence is complete.
Indicators
Five blue LED Status Indicators appear on the front panel. These indicators are
illuminated continuously when the system is functioning normally. See the table Front Panel
Indicators on page 103 for diagnostic meanings.

Rear Panel Features
Video Inputs
The Image Server records video on channel #1. It has separate BNC inputs for SDI
(serial digital per SMPTE 259M) and analog video (CVBS) signals. Both video inputs have a
fixed 75-ohm termination. The graphic user interface selects between the two. Encoding is
performed in MPEG-2 format within the server.
Video Outputs
Video outputs are provided in SDI and Composite (CVBS) formats simultaneously.
Digital video appears in SDI format at 270 Mb/s and conforms to SMPTE 259M. Analog video
is composite (CVBS).
Audio I/O
The Image Server provides audio inputs and outputs in three formats:
• Balanced analog audio at a reference level of +4 dBu.
• Digital audio in AES/EBU format per AES-3-2000.
• SDI embedded audio, 4-channels
These multiple standards facilitate the transition from an analog studio to digital
production and broadcasting, and ensure that the server can operate with most equipment.
Note that both analog and AES/EBU audio signals are not available at the same time on a given
input or output. Internal jumpers select between analog or digital; however, each pair of inputs
and outputs can be set up differently, if desired. A set of XLR-3 connectors allows high-quality
connections to be made in either format. Embedded audio appears in the SDI output stream at
all times.
Analog Audio Capability
When the analog audio input format is selected, each video channel has two audio
channels, recorded together as a stereo pair. Internal trimmers allow adjustment to unity gain.
Digital Audio Capability
When AES/EBU digital audio is selected, each video channel has four audio channels,
which are recorded as two stereo pairs. Because a single XLR connector carries a stereo pair in
AES/EBU format, and only one (monaural) channel in analog, the server provides an extra pair
of audio channels when used with AES/EBU audio signals.
Embedded Audio Capability
When SDI embedded audio is selected, four audio channels are available for recording.
Embedded audio is always inserted in the video outputs. Note that discrete audio (analog or
Hardware Interface 23
AES/EBU) is also available on XLR connectors, at the same time embedded audio appears in the
video stream. Embedded audio has a 20-bit resolution.
Audio Word Size and Sample Rate
The Image Server employs 24-bit audio A/D and D/A converters, and records audio into
a 24-bit frame, regardless of the word size received. The sample rate is fixed at 48K. When
using the AES/EBU digital input, the 48K sample rate of the incoming digital audio must be
derived from the video genlock reference. If it is not, or if a different sample rate is used, the
Image Server’s input sample rate converters must be selected.
Encoded audio streams such as Dolby E® must be referenced to the video genlock, and
the input sample rate converters must be disabled when recording such streams.
Analog/Digital Audio Selection
The following drawing illustrates jumper positions to select between analog or digital
audio. Note that each output may be individually selected. As described earlier, when analog
audio is selected, only two channels are available, while selection of AES/EBU digital audio
provides two stereo pairs, one on each XLR connector. Both jumpers for each channel (Left &
Right, or Main & Aux) must be set together, either analog or digital. The Image Server must be
power cycled for jumper changes to take effect. For more detail, see Analog/Digital Audio
Selection in the Maintenance chapter.

Serial Control Ports
Each of the Image Server’s three 9-pin “D” connectors permits independent control of
any of the three video channels. They can accept serial commands in VDCP, Sony BVW or
Odetics protocol. The multiple serial ports allow simultaneous connection of an automation
controller and a desktop controller. See the chapter on Automation Control for further details.
Most broadcast automation systems, and some remote control panels, employ the
VDCP protocol. A list of supported VDCP commands will be found in Appendix B.
24 Hardware Interface
Many controllers used for transport, instant replay, and edit control employ Sony BVW or
Odetics protocol.
Gigabit Ethernet Port
Gigabit Ethernet ports are provided on the Image Server. The NET 1 port is intended for
external transfer of program content between video servers. The server supports MXF file
transfer (MPEG-2, Op 1a and 1b), which allows content interchange between products from
different manufacturers, as well as file import in various formats from desktop editors.
The NET 2 port is reserved for future use and is not active. Use only the NET 1 port.
GPI Control
The Image Server provides six GPI inputs for control of machine functions, which
appear on the 25-pin GPI connector. This “General Purpose Interface” can be connected to
switch contacts or an open-collector transistor output. GPI inputs are programmable, and can
provide machine control such as PLAY, STOP, or RECORD through simple external switches.
The Image Server also provides six GPI status outputs which may be used to confirm
that a command has been received, or for other purposes. The function of these open-collector
outputs are programmable, and may be used to operate an LED, or they can be connected to a
suitable logic input. The pin-out for the GPI connector will be found in Connector
Specifications.
Genlock Sync Reference
A BNC connector is provided on the rear panel to receive a genlock signal. During
normal operation, the Image Server should be referenced to an external genlock reference in
the form of CVBS black. As with all video systems, this server and equipment connected to it
must be referenced to a common genlock source. The GENLOCK input provides a fixed 75-
ohm termination.
An internal crystal reference is also provided so that the server can be used as a standalone player, and also for convenience in performing tests in the laboratory. Use particular
care when operating the server with an internal reference, as synchronization with other
equipment is not possible.
Genlock Signal Quality
A genlock signal connected to the Image Server must conform to the RS-170A standard.
PLL circuits used within the server remove residual jitter from the genlock signal. This may
preclude the use of low-cost VCRs as signal sources, as they may introduce time instability
(wow) into their output, making them inaccurate as a genlock source.
LTC Time Code Input
A LTC time code input is provided on the LTC IN BNC connector. This input may be
selected by means of the On-Screen user interface and recorded as a time code reference. The
LTC input provides a >10k ohm termination.
Hardware Interface 25
LTC Time Code Output
An LTC time code output is provided on the LTC OUT BNC connector. It may be
selected by means of the On-Screen user interface to output time code from any of the three
video channels during playback. The LTC output has a source impedance of <5 ohms.
Keyboard
Attach the alphanumeric keyboard to the purple 5-pin KEYBD connector to control the
server and manage clips with the On-Screen graphic user interface. Note that the server will
only recognize the keyboard if it is attached before power up.
Mouse
A two-button scroll mouse is provided with the Image Server. Plug the mouse into the
green 5-pin MOUSE port. Do not use the USB ports, even if the supplied mouse is USB
capable. Note that the server will only recognize the mouse if it is attached before power up.
Monitor
A VESA-compliant computer monitor may be connected to the 15-pin VGA video port.
The Image Server resolution is fixed at 1024 x 768 pixels, with a refresh rate of 72 Hz. This is
best-viewed on 17-inch or larger monitors. 360 Systems does not provide monitors for the
server. Note: Do not use older monitors that are not VESA compliant. The server may not start
properly if an unsuitable monitor is connected.
Serial Port
The system board serial port is not used. Make no connection.
USB Ports
The system board USB ports are not used. Make no connection.
Power
An IEC mains socket is provided on the rear panel for power input. The Image Server
will accept world-wide power sources in the range of 100-240 volts AC, 50-60 Hz. The server
is shipped with a power cord appropriate for the region in which it is sold. Replace the power
cord only with one of the same type and rating.
DO NOT use the power supply switch to shutdown the Image Server. Shutdown the
system only by momentarily pressing the front panel power button, or through the HALT
command on the On-Screen user interface. The rear panel power switch should only be used
if the Image Server fails to shutdown after holding the front panel power switch for 4 seconds.
The rear panel power switch can be used to prevent the application of power during service
procedures once the normal shutdown sequence has completed.
The server may also be shut down from the graphic user interface. Click
START>SHUTDOWN>SHUTDOWN. After a few seconds, shutdown will occur.

Basic Operations
This section introduces the Graphic User Interface (GUI), its menus and operating controls.
If you want to skip ahead to learn how to record a clip, go to page 40. Skip to page 42 to read
about playing a clip.
The graphic user interface is a convenient way to manage Image Server operations. With it,
you can control recording and playout, set up video and audio formats, map remote control ports
to video channels, perform editing and make playlists.
All GUI software is pre-installed on the Image Server. It is also contained on the Image
Server software CD-ROM. The GUI is operated with a keyboard, mouse, and monitor connected
to the Image Server rear panel.
The Image Server Desktop
The Image Server desktop is similar to many computer graphic interfaces, and is always
running. A task bar and start menu appear at the bottom of the screen. Use the Start menu button
to launch applications, manage the system or to shut down the server.
Launching the Graphic User Interface
The GUI launches automatically during boot up. If it has been closed, click Start, then Image
Server GUI to re-launch it. The GUI window can be moved or minimized as desired.
Shutting Down Image Server
Click Start, then Shutdown, then either Halt>Shutdown to begin an orderly shutdown, or
Full Restart to do an orderly shutdown and Restart.
Alternatively, momentarily pressing the front panel power button will cause the system to begin
an orderly shutdown. Image Server will acknowledge the button press with an audible beep
and the front panel lights will begin to flash together. Any operation in progress will be halted,
and any unsaved work will be lost.
In the event that the system has stopped responding to commands and will not reset by
pressing the front panel button (no beep is heard), press and hold the button for four seconds to
force a power down. Wait 5 seconds, and then the system may be restarted with another press
of this button.
DO NOT use the rear panel power supply switch to shutdown the Image Server. Doing so
may cause loss of unsaved data, and may require the RAID drive array to re-synchronize – a
process that could take several hours. Shutdown the system only by momentarily pressing the
front panel power button, or through the GUI.
The Quick Restart option in the Start>Shutdown menu allows the GUI and video playback
application to be restarted without restarting the entire operating system. The Restart FTP
Only option will restart the FTP service without affecting video operation.
