Haivision Delivers Ultra-Low Latency 5G Video Transmission During Danish Elections
Haivision Systems Inc. announced that it powered ultra-low latency live video contribution over a private 5G network during coverage of the Danish general elections on Nov. 1, 2022.
Broadcasting the election live from the Danish parliament in Copenhagen, Denmark’s national public broadcaster, TV 2, was faced with the challenge of limited public network connectivity and the complexities of managing broadcast operations within the historical Christiansborg Palace. Providing live coverage from multiple rooms within the building meant that relying on traditional WiFi and public 5G cellular networks or using cables was too unreliable with limited bandwidth and higher latency. To overcome these obstacles, TV 2 deployed a nonpublic 5G standalone “network in a box” from Neutral Wireless both inside and outside of the building.
Following a longstanding relationship with Haivision spanning ten years, TV 2 turned to the Haivision Pro460 mobile transmitter along with the Haivision StreamHub receiver and decoder for video transmission at very low latency over the private 5G network. Live video was captured by two television cameras mounted with Haivision Pro460 mobile transmitters and sent to a Haivision StreamHub receiver over 5G. The live video was then decoded by StreamHub and delivered to TV 2’s Copenhagen production facility over a dedicated fiber network. With Haivision 5G contribution technology, initial tests demonstrated end-to-end latency of less than 100 milliseconds from the parliament building to its production facilities.
“The election coverage proved to be a huge success as our goal was to follow the results as closely as possible and reliably transmit coverage in real-time,” says Morten Brandstrup, Head of News Technology, TV 2 Denmark. “Haivision video transmitters were easy to deploy and worked seamlessly over our private 5G network, allowing us to achieve low latency transmission without compromising reliability or quality.”
“Haivision technology continues to blaze a trail for low latency mission-critical video transmission over cellular networks,” says Ronan Poullaouec, Senior Vice President, Engineering, Haivision. “We are always pushing the limits of what’s possible with 5G connectivity for our customers and we are delighted to bring audiences exceptional quality viewing experiences in near real-time.”
