Dilithium Technology

3G-324M/H.324M Multimedia Protocol Stacks

Dilithium is the market leader in 3G-324M/H.324M protocol stacks. The Dilithium 3G-324M/H.324M stack has been available since 1999 and is one of the most mature and interoperable products in the market.

The Dilithium 3G.324M/H.324M protocol stack has been designed to safeguard service-level quality in low bit rate/low bandwidth networks such as PSTN/GSTN type analogue telephone networks and error-prone wireless networks. It is fully compatible with 3G-324M, making it a popular choice for deployment as a real-time multimedia streaming handset solution for 3G wireless environments, and H.324M/H.323/SIP media gateways for 3G wireless and landline networks.

* 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.

Platform Support

Dilithium stack has a modular architecture with a unique API allowing fast retarget to new platforms. It is currently available on a wide range of platforms and operating systems. If time to market is critical, customers can take advantage of the Dilithium Professional Services who provide rapid targeting and optimization services. Our team has experience with many processors, operating systems and platforms.
