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 Transcoding Media Gateway is intended for carrier class applications. The DTG 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 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/H.324M/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.
