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

Hitomi MatchBox

Hitomi Broadcast, market leader in audio/video alignment and latency tools, is showcasing its latency and synchronisation tools at NAB2023 (booth N2860, Las Vegas Convention Center, 16 – 19 April). With the rapid growth in remote production and IP contribution, these simple and cost-effective tools are more in demand than ever. 

New for NAB 2023 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 recognised 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 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.” 

Hitomi can be found at NAB2023 in the UK Pavilion, at booth N2860. Full information on the company and its products is at hitomi-broadcast.tv, and a quick guide to aligning latency and lip-sync is at https://youtu.be/QSYurg_Oy0g.
