Media device systems and methods synchronize video content with audio content presented by a plurality of wireless audio headsets. In an exemplary embodiment, a first time delay corresponds to a first duration of time between communication of the audio content from the media device and presentation of the audio content by a first wireless audio headset. A second time delay corresponds to a second duration of time between communication of the audio content from the media device and presentation of the audio content by a second wireless audio headset, wherein the first time delay is greater than the second time delay. Video content communicated to a display is delayed by the first time delay. Audio content communicated to the second wireless audio headset is delayed by a time delay difference between the first time delay and the second time delay.

Vehicle event data playback systems described herein may provide users means for reviewing events recorded by a vehicle event recorder. Circumstances relating to vehicle operation may be visually presented in these playback systems. Video playback from multiple recording devices may be synchronized with each other and/or with information related to the operation of the vehicle during the recorded events to affect a presentation of information related to operation of the vehicle. A user may be presented with many data types in graphical and/or intuitive arrangements.

A method of playing audio content to a viewer in synchronization with a video content. The method comprises receiving and digitizing an ultrasonic signal comprising ultrasonic synchronization signal(s), the ultrasonic synchronization signal(s) comprising a timecode-carrying part that encodes a respective timecode through modulation of ultrasonic carrier signal(s), the ultrasonic synchronization signal(s) comprising further an ultrasonic marker signal conterminous with the timecode-carrying part. The timecode-carrying part is identified based on a received ultrasonic marker signal and decoded to determine the corresponding timecode. The stored audio content is played back from a playback point determined based on the timecode.
