Dilithium Technology

Mobile Terminals

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.

3G-324M Acceleration

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. It 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.
