* 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.
