The TVG450 provides a simple solution for transport of broadcast quality television signals over IP networks. JPEG 2000 encoding technology enables transport of SD, HDTV, Stereoscopic 3D HDTV and 3 Gbit/s HDTV over Gigabit Ethernet links.

The JPEG 2000 Gateway enables broadcasters to utilize cost-efficient IP links for high quality, low latency contribution. MXF/IP encapsulation ensures perfect synchronization of all video, audio and ancillary data.

TVG450 enables service providers to utilize visually lossless, multi-generation resilient JPEG 2000 encoding, and IP/Ethernet technology, to build cost effective managed video services on top of IP-MPLS, Metro Ethernet or SDH/SONET transport networks.

Nevion Media Gateways can be configured via an easy-to-use web interface, which also offers extensive built-in monitoring. Dynamic and scheduled connection management for larger deployments can easily be facilitated with the VideoIPath media network management system.
