MGW 3100 is a video-over-IP rack-mount system that bridges digital video and high-speed data networks. MGW 3100 creates new opportunities for service providers by serving as a media gateway between DVB and IP/ATM networks. MGW 3100 is ideal for applications such as Backhaul video over IP and ATM networks or bridging DVB and IP interfaces at headend installations. For IP headends, MGW 3100 provides re-distributions of received MPEG-2 DVB stream onto IP based networks.
MGW 3100 receives MPEG-2 DVB-ASI streams (SPTS or MPTS), encapsulate the MPEG-2 (SPTS or MPTS) in IP (IPoA optional) using the RTP standard, and transmits them over the network. At the receiving end, an MGW 3100 system receives the MPEG-2 /IP stream, extracts it, and plays back a DVB-ASI stream. Alternatively, an IP based set-top-box can receive and play back the stream. By combining RTP transmission, Diffserv QoS support and unique error correction mechanisms, MGW 3100 ensures efficient and reliable transmission over IP networks.
MGW 3100's Remote Session Manager allows you to control unicast and multicast transmissions from one MGW 3100 system to single or multiple MGW 3100 receiving systems. The Remote Session Manager can communicate with one transmitter and up to 20 receivers simultaneously and allows configuration, operation and on-going monitoring of the transmission.
