8 = Introduction 

360 Systems’ Image Server 2000™ and Multi-Format Image Server are multi-stream video 

recorder/servers designed for television broadcast, production, and Pro-AV applications. Image 

Servers can play three independent v ideo streams at once, and store up to 170 hours of MPEG-2 

video, with four audio channels per video stream, in just 3½” of rack space.  The server’s extensive 

feature set makes it an excellent choice for VTR replacement, automation, remote trucks, P-E-G 

applications, corporate and entertainment presentations. The Image Server is produced in both 

NTSC and PAL models.  References in this document to frame counts other than 29.97 or 30 
frames should be understood to be a PAL example.  

The Image Server smoothes the transition to digital production and broadcasting by 

providing both composite video (VDCP) and serial digital (SDI) interfaces, plus network transfers in 

MXF format over Gigabit Ethernet. It’s never necessary to add additional video A/D or D/A 

converters, and a full complement of premium -quality MPEG-2 codecs is included as standard 
equipment.  The server’s dual analog and digital personality—for both video and audio—lets it fit 

seamlessly into an existing analog facility, or become part of a new digital build-out. Apart from 

serving its intended purposes, the Image Server is also valuable for its ability to convert between 

different analog and digital media formats in real-time. 

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 from 52 to over 170 

hours of storage at 12 Mb/s (Megabits per second).  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 keeps the server in service, even with a failed 

drive.  The multi-drive array also generates the high data rates needed for multiple video streams at 

up to 50 Mb/s, and enables fast program transfers through the Gigabit Ethernet ports.

The Image Server’s unique ability to play two video streams while recording another, and 

at the same time perform network file transfers over Ethernet, makes it far more than just a 
replacement for a VTR.
