The
delivery of video services is far more complex than
that of pure voice or data. Dilithium engineers and
technical experts have been involved in broad range
of standard and technology development in the
audio/video compression and multimedia communication
areas since the early 1990s. Today’s Dilithium
products and solutions are underpinned by many of
these technologies, either in a unique offering or
as part of the standards.
Multimedia Transcoding Gateway
The DTG 2000 is a Transcoding Media
Gateway Controller intended for carrier
class applications. The DTG 2000
supports a variety of voice and video
protocols, and features smart end-point
capability processing to provide
transcoding tailored to end-points such
as mobile phones, PDAs, ISDN phones, and IP
terminals. The DTG 2000 provides
transcoding and proxy functions for call
signalling, call setup, command, control and indication
between various multimedia systems standards including
H.324M/3G-324M, H.323 and SIP.
MONA/WNSRP
Dilithium played a key and leading role in the
definition and the standardization of ultra fast
session setup acceleration techniques for 3G
videotelephony (3G-324M). Dilithium's AnswerFast technology suite forms the basis of the ITU-T H.324
Annexes A (WNSRP) & K (MONA).
WNSRP (windowed numbered simple retransmission
protocol) is a technology that allows the pipelining
of H.245 frames.
MONA consists of an
algorithm that allows 3G terminals to exchange their
preferences early and to start media exchange within
1/2 round trip. MONA significantly improves the
videotelephony customer experience by reducing the
session setup time to under 1 second, comparable to
voice calls. Dilithium holds patents essential to
the implementation of WNSRP and MONA.
3G-324M Technology
Dilithium is the pioneer and market leader in
3G-324M/H.324M solutions. The Dilithium 3G-324M/H324M/H.323M video solutions offer the fastest session setup time
and the most mature and interoperable protocol
implementation in the market. Our engineers also
participated in the development of the H.324 and
H.324M ITU-T Standards since the early 1990's.player |
