MatchBox is a state-of-the-art audio video alignment tool

Have you ever watched TV and noticed that sometimes the sound and pictures don't match up properly – the Lip Sync is off? The path from camera lens to television screen is complex and varied. For a live broadcast, it will be different every time.

It may be necessary to separate the sound and pictures at various points as they travel through the process. This is where they can encounter different delays and arrive at the destination at different times. The result of which is a “Lip-Sync Error”.

Using eye and ear alone to align the delay is very subjective as people’s perception of what is correct can be very different. What is needed, is a precise measurement tool. Hitomi MatchBox accurately measures audio and video alignment so that the exact amount of correction can be applied.

Avoid misalignment

and the disputes that follow

 

When a lip sync error occurs on a live broadcast everyone in the chain worries if they are responsible. This can lead to some unfortunate disputes. With Hitomi MatchBox, accurate synchronisation on departure can be demonstrated, as can misalignment on arrival. Evidence based data can mitigate liability.

Testimonials About Us

  • Our MatchBoxes are an absolutely essential piece of equipment which enables us to quickly analyse where any delays are in the chain.

    Timeline
  • With 4K transmissions, there is a relatively high processing delay for video compared with the audio. The only way to measure the discrepancy out of the HEVC encoder is by using a Hitomi MatchBox
