TVU One/PRS One backpacks covering fast-paced live basketball matches
Hikari TV, a Japanese subscription-based streaming and broadcast service, recently deployed TVU One and TVU PRS One backpacks to deliver coverage of an inter-high school basketball tournament in Japan.
The deployment this June enabled simultaneous television broadcast recording and live YouTube streaming throughout the tournament. To facilitate this, the media production team implemented an efficient workflow addressing basketball broadcasting’s unique challenges.
Given the sport’s fast-paced nature and critical requirement for real-time communication, all camera switching operations were performed directly at the venue to ensure immediate responsiveness to game action.
The Media Production Team’s Yamaguchi explained, “Basketball is a fast-paced sport that requires zero-latency intercom communication, so camera switching was done on-site. The switched output video, along with camera sources such as scoreboards and overhead shots, was transmitted in parallel to the station using TVU One and TVU PRS One backpacks.
“Final video mixing and commercial insertion were handled in the studio sub-control room at the station before transmission and recording.”
The production workflow maximised TVU backpacks’ parallel transmission capabilities, sending multiple video feeds simultaneously to the broadcast station’s studio sub-control room. This approach supported post-production work that included final video mixing and commercial insertion while maintaining the live broadcast schedule.
The TVU implementation delivered significant operational benefits that streamlined the entire production process. The advanced transmission systems achieved stable video transmission without requiring fibre optic installation at the venue, eliminating costly and time-consuming infrastructure work.
The systems enabled parallel transmission of footage from cameras positioned in challenging remote locations, such as above the stands, significantly reducing on-site setup burden and cable management complexity.
Most importantly, there was virtually no delay difference between all seven TVU backpacks, dramatically reducing time needed for technical adjustments and synchronisation. This consistency allowed the production team to focus on content creation rather than technical troubleshooting, said TVU Networks.
