NAB 2023: Hitomi Broadcast Unveils New Cloud-Based Lip-Sync Measurement Tool

Hitomi Broadcast is showcasing its latency and synchronization tools at NAB 2023. New for the show is lip-sync measurement in the cloud. Attendees will be able to see a live demonstration of a file-based version of MatchBox.

MatchBox is now widely recognized as an industry standard in lip-sync measurements, and the latest MatchBox Glass iPhone app makes it even simpler to very 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 minimizing latency, Hitomi now recommends using MatchBox Latency to establish the delay over each circuit, before using MatchBox to synchronize pictures and sound. The same MatchBox analyzer 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 realize 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.”
