Spanish TV and radio broadcaster RTVE took a ground-breaking approach to production of a recent live concert of Radio 3 from Madrid’s Casa America palace. The multi-camera event featuring top Latin American performers was mixed and distributed entirely within the cloud-based TVU Producer live production platform. From TVU Producer, the sources were synchronized, then mixed, graphics added, and signals distributed directly to RTVE’s broadcast and digital networks.
Unique to the TVU Producer platform is the ability to distribute seamlessly a live event to any output – SDI or landscape and vertical formats for social networks – from the cloud with virtually no latency.
“We were able to set up our multi-camera production incredibly fast and with minimal equipment and expense” said Tomás Fernando Flores, Director of Radio3. “The production and distribution were entirely managed in the cloud. With the click of a button, we sent a very high-quality stream, perfectly synchronized, to every platform in the correct format. I’m thrilled with what we delivered to our audience. We have a solid history of innovation at Radio 3, and our recent application with TVU Networks solutions will change how we produce future live events.”
This concert also marked the first time a 5G mobile transmitter was used for a live stream in Spain.
The multi-camera signal from the recent Radio 3 concert was acquired with a traditional broadcast camera equipped with a 5G TVU One mobile transmitter and three smart phones with the TVU Anywhere mobile broadcasting app (for fixed and moving images.) The TVU One unit was equipped with six modems – two supporting 5G and four supporting 4G/LTE networks. The audio from the radio broadcast served as the only audio reference distributed to all devices and broadcasts of the coverage.
TVU Producer’s multi-channel IP video switcher automatically synchronizes its output to all receiving devices. Images were sent in the varying formats required for broadcast and streaming, including a specific vertical output for Instagram. The platform’s 9:16 Vertical Video feature allows users to simultaneously produce a live program in landscape and portrait mode.
