10 = Introduction 

Image Servers include both analog and digital audio circuits, making it an important tool in 

the transition to digital broadcasting.  It includes gold XLR connectors for audio inputs and outputs, 

and each can be configured for either AES/EBU digital or +4 dBu balanced analog.  SDI embedded 

audio is also available as an option.  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.) 

360 Systems brings over 30 years experience  in broadcast and pro-audio to the audio 

design of Image Servers.  It utilizes a 24-bit word, and delivers a 20 dB improvement in SNR (10 

times!) compared with older 16-bit audio systems. An insertable sample -rate converter is included, 

plus input circuits with excellent hum and RF rejection, and 20 dB of headroom.  360 Systems’ Bit-

for-Bit® design strategy guarantees that when a Dolby®-E, Dolby AC3, or any other encoded 

program is recorded, it will play back correctly.  

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, which includes 

transport control buttons, clip file management and head and tail trimming, allowing the Image 

Server to operate as three self-contained VTR equivalents. 

System configuration is clear and straightforward with the On-Screen 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. 

The GUI can be remotely accessed by a Windows PC through an Ethernet link, or of a 

wide-area connection using a high-security remote KVM product. Contact 360 Systems sales for 
complete information on these options.  

Image Servers move beyond providing just a simple base-band solution for video input and 

output. MXF file transfers over Gigabit Ethernet open the door to new IP solutions for transferring 

video across the room—or across the country—at exceptionally low cost. 

By using economical switches  and computer-industry infrastructure, the Image Server’s 

Gigabit Ethernet 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 uses Operational Patterns 1a and 1b.  It has been tested 

for compatibility with MXF files from many other manufacturers.  360 Systems can make Im age 

Server  MXF files available for testing and evaluation through our FTP Site.  Contact the customer 

service department to arrange for access.
