DTG® 3000 Dilithium Transcoding Gateway

  
   

The DTG 3000 Multimedia Gateway Family provides the multimedia solution for cellular, IP, and PSTN convergence as networks evolve towards the IP Multimedia Subsystem (IMS).

The DTG 3000 Multimedia provides real-time transcoding, proxy functions for call signaling, command & control, and voice and video transcoding between multimedia systems protocols including 3G-324M/ H.324M, ITU-T H.323 and the IETF SIP.

The DTG 3000 supports all 3G multimedia applications and provides transcoding tailored to end-terminals such as mobile phones, PDAs, and IP terminals. The DTG supports a variety of voice and video coding standards and connects end-terminals on circuit switched, packet switched networks, wireless networks and the PSTN.

The DTG patented technologies enable rapid session setup, minimal media delays and skews, while ensuring the widest interoperability and unparalleled user experience and media quality.

* 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 Annex K, also known as MONA (Media Oriented Negotiation Acceleration). MONA consists of an algorithm that allows 3G terminals to exchange their preferences early and to start media exchange within 1/2 round trip. This standard significantly improves the videotelepehony customer experience by reducing the session setup time to around 1 second, comparable to voice calls. Dilithium and PacketVideo are the co-editors of this standard.
