8 Introduction
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 house-
of-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 multi-
drive 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.

IMAGE SERVER MAXX STORAGE TIMES
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

Introduction 9
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.

10 Introduction
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 VESA-
compliant 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.

The Image Server is not shipped with a video monitor. Select a VESA-compliant CRT or
LCD monitor suitable for your application. Note that the Image Server may not start correctly if an
unsuitable monitor is connected.
If you own more than one Image Server, it may be appropriate to use a single keyboard,
monitor, and mouse with a KVM switch to select between servers.

16 Installation
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 inside the rack? Do this near the top.
•Verify that the HVAC system is not on a timer that can shut off on weekends or holidays.
•What procedures are in place to protect the equipment when the HVAC system fails?

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:
