The 7881ENC offers an auto-sensing HD/SD-SDI digital interface with 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 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.
