WGAL, a TV station based in Lancaster, Pennsylvania, USA and affiliated to NBC, is delivering its daily weather broadcasts to viewers from the home of its chief meteorologist, Joe Calhoun.
It has been doing this during the COVID-19 pandemic with the help of TVU Networks, a provider of cloud and IP-based live video technology.
As COVID-19 restricted in-studio reporting, the station turned to TVU Grid, an IP-based point-to-multipoint live video distribution system to deliver professional, remote weather broadcasts over the internet with as close to studio quality as possible.
“The pandemic forced us to start thinking outside the box when it came to remote work,” said Kevin Kalia, Director of Engineering at WGAL. “The secret was sending a broadcast-quality feed of Joe’s weather graphics to him, keying his shot with a switcher at his location and then sending a program feed back to the station – all with TVU.”
By using TVU Grid’s bi-directional feature, WGAL was able to provide studio capabilities to Calhoun to deliver the weather forecast almost as if he were live in the studio. The station set up a green screen with graphics and pushed it from master control to Calhoun’s home for presentation while providing video content from his home back to the studio. All of this was accomplished with HD video and low-latency using TVU Grid.
TVU Grid delivers scalable point-to-multipoint switching, routing and distribution of live video over IP. TVU Grid is used by news agencies and media organizations around the world to share and exchange live broadcast quality video feeds with latency kept as low as possible given other constraints. It uses commodity internet to deliver the video as a cost-effective alternative to traditional fiber and satellite.
