SeaChange’s Next Generation Broadcast Systems and MediaLibrary Debut at NAB2004

MediaCluster’ Architecture Yields FurtherPerformance Advantages for Television Broadcasters Amid Fast-Changing Industry Dynamics

(PresseBox) ( Herrsching, )
MAYNARD, Mass. (March 23, 2004) – SeaChange International (Nasdaq: SEAC) enters NAB 2004
with a powerful array of next-generation on-air and online systems based on its patented
MediaClusterTM architecture. More than 15,000 SeaChange video servers are deployed by television
operators worldwide, including 270 broadcast stations, networks, and satellite operators. Reflecting
its extensive experience in television, SeaChange debuts advanced server platforms and media prep
tools for broadcast television enterprises adapting to fast-changing industry dynamics.
“Television’s evolution is creating new expectations for viewers,” said Ira Goldfarb, senior vice
president, worldwide sales, SeaChange. “Viewers are demanding more choices in programming and
unscheduled access. They are setting the bar higher for broadcasters. SeaChange systems take the
fundamental advancements in video storage and networking to help broadcasters establish new
viewing models, streamline their operations and connect in more ways with their viewers.”

Universal Storage for the Media Enterprise

NAB 2004 features the next generation SeaChange Broadcast MediaLibrary 2G (BML 2G)
online storage system, which supports Serial-ATA or SCSI drives in compact 6RU (rack unit), 4RU or
2RU chasses. A fully configured BML 2G system brings 1,080 disks on-line for universal, formatindependent access to over 240TB of RAID2 (‘RAID Squared’)-protected storage.

Broadcasters are using BMLs to establish cost-efficient, universal storage for on-air servers, editors,
VTRs and other media devices throughout their operations. Its accessibility is enhanced by the new
SeaChange IP Accelerator Card. Supporting FTP, HTTP, and the widely-adopted SMB/CIFS
(Common Internet File System) protocols, the IP Accelerator off-loads TCP/IP-based file access from
the host CPU and provides cluster-wide data striping; provides parity generation during file writes;
and regenerates missing data during file reads. Nodes in a BML 2G will initially support up to four IP
Accelerator Cards, each providing up to 300Mb/s of file I/O bandwidth allowing bandwidth and
storage to be scaled independently.

“Parallel access to media content empowers broadcasters to more efficiently create new forms of
programming and to better leverage it over various forms of distribution, both traditional and new,”
said John Pittas, vice president, broadcast systems, SeaChange. “The MediaLibrary provides a parallel
access model for media creation, packaging and distribution, helping establish a more collaborative
workflow in all phases of content lifecycle. With support for industry-standard IP data networks and
file access protocols, coupled with high-bandwidth access to the industry’s most economical faultresilient
storage, the MediaLibrary provides an open, scalable and future-proof investment in
universal content storage that can be used throughout the media enterprise.”

The BML 2G can also integrate Windows Media 9 Server to provide cost-efficient content browsing by
thousands of concurrent users to potentially millions of media files.

Surpassing MediaCluster’s Benchmark On-Air Performance
For broadcasters serving multiple on-air channels of high bit-rate video, SeaChange debuts the
SeaChange Broadcast MediaCluster (BMC) 60000. Yielding a performance leap from the
original BMC platform, the third-generation BMC 60000 node supports up to eight MPEG-2/IMX
codecs (up to 62Mb/s per codec); or four MPEG Transport I/O cards; or three High Definition

Combining as many as seven nodes in a BMC 60000 system, broadcasters can secure up to
56 channels of 50Mb/s IMX I/O and over 1,600 hours of storage using the industry’s newest 300GB
SCSI disk drives – all in a fault-resilient platform that requires only a single copy of any file to support
any number of concurrent I/Os.
Maximizing media workflow, each BMC 60000 node can also provide 100Mb/s of file transfer bandwidth to IP-attached clients for an aggregate of 700Mb/s of IP bandwidth.

Broadcasters requiring higher I/O channel counts will turn to the new SeaChange Broadcast
MediaCluster 15000. This on-air platform can be configured with as many as seven nodes, each
node allowing 10 MPEG-2 codecs (up to 15Mb/s per codec). With up to 12 300GB SCSI disk drives
per node, a seven-node BMC 15000 system supports 70 I/O channels and exceeds 3,000 hours of
storage at 12Mb/s. Each BMC 15000 node can also provide 80Mb/s of file transfer bandwidth for an
aggregate of 560Mb/s of IP bandwidth.

Seamlessly Integrating Content Preparation
At NAB, SeaChange will also present a range Content Preparation Tools to maximize productivity
between on-air BMCs and popular edit workstations:
- SeaChange MediaMarker for PC-based browser/cue-marker for HD and SD MPEG-2 streams;
- SeaChange MediaDub for Avid workstations: Import/export via SDI/AES record/play;
- SeaChange MediaTransfer for Avid NewsCutters: Import/export of IMX files via Avid Transfer
- SeaChange MediaPublisher for Adobe Premiere: Import/export of MPEG-2 files;
- SeaChange SeaMux for Adobe Premiere: Builds multi-language audio multiplexes using the
SeaChange MediaPublisher.
