Introduction
360 Systems’ Image Server™ 2000 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 2000 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 2000 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 2000 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 52, 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.

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
combination of tasks, including responding to GUI or automation commands, clip trimming or
browsing.
