SEN’s head of production for TV Peter Morris set the scene. “We produce live and pre-recorded TV programs from our state-of-the-art studios in Southbank as well as end-to-end live sport coverage for broadcasters including Nine, Seven, SBS, Fox Sports and ESPN. To complement this offering we decided to build an OB-type operation without all the usual major costs involved and for that we needed Digistor to supply us with multiple Dejero EnGo units, as they use a bonded cellular system to transmit high-quality live video with low latency.”

Morris and his team made their decision on prior experience of Dejero products. The objective this time was to target second-tier sports where there is still some demand for broadcast coverage but without the potential revenues to justify a full-blown OB with trucks and tens of people on the ground.

The new OB system involved stacking all encoders side by side and then developing software that would work with the Dejero EnGo units to capture and lock together each signal in perfect sync as it returned to Melbourne where SEN is headquartered.

The Dejero EnGo was designed as a durable and versatile mobile transmitter purpose-built for sending high-quality live video from remote locations as reliably as possible. It uses Smart Blending Technology to provide reliable connectivity for low latency live video. EnGo enables users to transmit high-quality live video with latency down to 0.8 seconds depending on distance.

HEVC compression is used at bitrates up to 20 Mb/s at 1080p 50/60 with hybrid hardware/software encoding dynamically adapting in real time on the basis of video scene complexity.
