Video Synchronization

Video Synchronization for Multilingual Tour Content

Video synchronization refers to the relative timing of an audio track compared to the video playback accompanying it. This is an extremely important feature to have in a museum, especially when video is offered in many languages. For example, a movie playing in a gallery may be in English but have dubbed audio content in several other languages. With video synchronization, a visitor who speaks French could immediately tune in to the French audio track of the film, at any point during playback.

The process of video synchronization is fairly simple. A device called a driver is connected to the multimedia player, sending out a timecode signal to visitor’s device. The app receives the signal and returns audio content synchronized to within a tiny fraction of a second. With this technology even lips are perfectly synchronized with sound, so that visitors will notice no delay whatsoever. Our technology is also compatible with hardware such as Orpheo audio-guides, iPods, and Android devices.
