Dilithium Extends its Technology Leadership with New Multimedia Gateway Release

Dilithium, the leading supplier of converged video solutions,
announced the 2.2.1 release of its latest DTG 2000 Multimedia Gateway
incorporating state-of-the-art video technologies of MONA, WNSRP,
H.264 video transcoding as well as extended IMS support. The DTG 2000
Release 2.1.1 is available immediately.

MONA (Media Oriented Negotiation Acceleration or ITU-T H.324 Annex
K) is a recently standardized video session set-up time acceleration
technique that significantly improves the video customer experience by
reducing the session setup time to around one second, comparable to
voice calls. The new release DTG fully supports all of the three MONA
terminal classes for the best performance and flexibility with any
handset. Full support for WNSRP (Windowed Numbered Simple
Retransmission Protocol) is also provided in this release. WNSRP
accelerates the transport of command and control messages in video
calls. The MONA and WNSRP techniques are mandated by the ITU-T and
recommended by 3GPP for video calling technologies, including video
value added services, and use Dilithium technologies at their core.

"The DTG 2000 now also incorporates end to end support for H.264.
The H.264 video codec, which delivers stunning quality at the low data
rates used in wireless communications, was ratified as part of the
MPEG-4 standard (MPEG-4 Part 10) as well as ITU-T Recommendation
H.264," says Mitch Lewis, Senior Vice President for Dilithium"s
Service Provider Business Unit. "This ultra-efficient technology
provides excellent results across a broad range of bandwidths, from 3G
mobile devices, broadband and internet, to HD for broadcast and DVD.
Earlier releases of the DTG 2000 supported H.263 and MPEG-4 video
(MPEG-4 Part 2) with full transcoding, transrating and Video
Refresh(TM) support."

The DTG 2000 is the leading multimedia platform enabling a wide
range of converged video value added services such as live TV, video
portals, video surveillance, video blogging, video push, and video
ring back tones. These applications enable operators to create and
offer enhanced video services such as video ringback tones, video
chat, video blogging and live TV. The DTG 2000 is also used as a
combined IMS (IP Multimedia Subsystem) video gateway, and more
specifically as a MGCF/IMS-GW (Media Gateway Control Function and IMS
media gateway). Dilithium is the first to market with a multimedia
gateway incorporating these technologies.
