INTRODUCTION
360 Systems’ new Image Server 2000™ is a multi-stream video recorder/server designed for
television broadcast and production. It can play three independent video streams at once, and
stores up to 100 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, and new IP-based designs including MXF network transfers. The Image
Server 2000 is produced in NTSC and PAL models. References in this document to frame counts
above 25 frames should be understood to be an NTSC example; an appropriate PAL frame count
should be assumed for PAL servers.
The Transition to a Digital Plant
The Image Server smoothes the transition to a digital broadcasting plant by providing
composite video 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. Its dual
analog and digital personality helps it fit seamlessly into an existing analog facility, or become part
of a new digital build-out.
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 from 48 to over 100
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 on-air- 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.

IMAGE SERVER 2000 STORAGE TIMES
The Image Server 2000’s ability to play two video streams while recording another, plus
simultaneous MXF file transfer over Ethernet, make it far more than just a replacement for a VTR.
