H.264/AVC Low Latency Contribution Encoder

Product Manual Manual
VistaLINK® enabled New IPX Enabled

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 Evertz's 7881DEC-H264HD 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
