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.

    Dan McDonnell Managing Director 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
