More and more content producers are realising the production value of creating live content in IP
The 2018 Commonwealth Games, held from April 4-15 on the Australian Gold Coast in Queensland, was the fifth Commonwealth Games hosted by the land Down Under.
As the host nation romped home with the most medal wins, the XXI Commonwealth Games also provided a significant technology footnote: NEP Host Broadcast helped Seven Network, the Game’s Australian rights holder, to transport multiple live HD signals over IP connections between various venues and the International Broadcast Centre (IBC).
NEP’s requirements were to send 10 HD-SDI video, along with up to eight audio channels from multiple remote venues, back to the IBC, while simultaneously sending HD-SDI video and audio channels back from the IBC to each of the remote locations.
To achieve this, NEP chose a joint solution from Caton Technology and Digistor. Andrew Mooney, managing director of Digistor, described to APB: “Our set-up involved the use of multiple Caton Integrated Video Processor (IVP) devices and their proprietary R2TP protocol to ensure reliable real-time delivery of HD signals from the various venues back to the IBC via an IP link.”
One of the challenges faced, he identified, was the need to ensure absolute minimal latency, along with a very high bitrate (60Mbps), while maintaining adequate buffers for any packet loss, jitter or delay on the IP link.
“Luckily, the IVPs are quite configurable and we were able to address these requirements,” Mooney related. “The incoming feeds were being used for live interviews with return video, so latency was particularly important.”
