Overview
As the development of all-IP-base for audio and video services, most of operators have been engaged in transforming and developing in IP network, for the replacement of traditional DVB network. As a result, DMB-4000 All-IP Series come to birth. This products awards with definite approval and fame from the market, due to their high commercial value and low operation cost. DMB-4000 series realizes seamless joint with IP network, and receives transport streams from main IP network. A single unit can process serial of high-integrated work of de-capsulation, re-multiplexing, DVB scrambling, DVB-T/DVB-C modulation, etc. for IP transport streams. Device of this series is standard 1U machine installed different modules(MC200,MT200).
