VistaLINK® enabled New SDVN Compatible

As the broadcast landscape continues to evolve, the need for a superior class of compression encoder that applies the latest compression technology becomes more relevant to overall success of the operation. The Evertz® 7881ENC-H264HD (7881ENC) video contribution encoder satisfies this very requirement.

This module has been designed for high quality, low latency compression of HD/SD-SDI video and audio signals over any transport network, including IP/MPLS, satellite and sonet. The encoder is equipped with an enhanced H.264/AVC (MPEG-4 Part 10) video compression engine that delivers contribution high quality video with super low latency as low as 120ms end to end when paired with an Evertz professional decoder.

This device offers an auto-sensing HD/SD-SDI digital interface with up to High Profile 4:2:2 video compression resolution at user configurable bitrates of up to 80Mb/s with support for forward error correction (FEC) and integrated encryption technology to ensure security across the transport.

The encoder also includes a dedicated control port that offers a built-in web server for quick and easy configuration, including true SNMP control from the award winning VistaLINK® NMS when paired with a frame controller.

For those mission critical applications, the 7881ENC-H264HD can be smartly managed using the Evertz® Compression System Manager (CSM) software, which offers complete provisioning, monitoring and redundancy management of the contribution compression head end.

This module can be housed is a wide variety of Evertz® chassis spanning from 1RU, 3RU and 6RU enclosures. The 7881ENC-H264HD will occupy one slot of the chassis.*
