NAB 2023: Hitomi to unveil new cloud-based lip-sync measurement tool

Hitomi Broadcast is set to showcase its latency and synchronisation tools at NAB 2023. New for the show is lip-sync measurement in the cloud, while attendees will also be able to see a live demonstration of a file-based version of MatchBox.

The latest MatchBox Glass iPhone app is said to make it simple to quickly line up each camera feed. With remote productions like major sports sending very large numbers of feeds back to the central control room, managing lip-sync is critical.

The latest addition to MatchBox is the ability to measure end-to-end latency over a broadcast path. Given the need for minimising latency, Hitomi now recommends using MatchBox Latency to establish the delay over each circuit, before using MatchBox to synchronise pictures and sound. The same MatchBox analyser provides highly accurate readings of latency and lip-sync shift, ensuring precision alignment based on data rather than trying to match them by eye.

“NAB is a really important event for us, because you really have to see how simple the MatchBox system is to realise how it can transform outside broadcasts and remote productions,” said Russell Johnson, director at Hitomi. “It also gives us the chance to showcase the latest developments, like our commitment to SMPTE ST2110, and our solutions for MatchBox in cloud architectures.”
