NX4600 (DISCONTINUED) H.264/AVC Media Gateway

Nevion’s NX4600 is an H.264/AVC encoder, decoder and media gateway all built into one. With its high density (up to 4 encoders or decoders in a 1RU form factor), it is specifically designed for applications, such as sports or news broadcast contribution, where multiple high quality video streams need to be transported reliably and with very low latency on network connections that have relatively constrained bandwidth.

The NX4600 enables up to four baseband SDI video signals to be encoded using H.264/AVC or MPEG-2 compression and transported over ASI and IP, with aggregation of TS over IP streams on one or multiple GbE ports if needed. It is also possible to combine encoding and decoding in the same unit, and switch between encoding and decoding, making the NX4600 the most versatile media gateway on the market today.

The NX4600 includes Nevion’s trademark advanced protection mechanisms that enable real-time transport of professional media over IP networks with extremely high availability. The H.264/AVC Media Gateway offers built-in Transport Stream monitoring of both encoder outputs and decoder inputs, as well as SDI and RTP/IP monitoring – all of which helps anticipate and correct any issues with input signals or networks should they arise.

Nevion’s NX4600 can be managed easily through a web-interface or via VideoIPath, Nevion’s media service management solution.

The NX4600’s high-density, flexibility, aggregation, monitoring and ease-of-use makes it eminently suited for applications such as broadcast contribution over low bandwidth or environments with rapidly changing requirements such as occasional use deployments.
