System for recording and synchronizing audio and video associated with a UAV flight
First Claim
1. A method for encoding time stamp information within a video recorded using an unmanned aerial vehicle (UAV), the method including:
- receiving GPS (global positioning system) time information using a GPS receiver on the UAV;
providing the GPS information to a real-time clock on the UAV to trigger the real-time clock;
initializing video recording via a camera supported by the UAV; and
encoding time data from the real-time clock into the video recording using a video encoder on the UAV.

Abstract
A method for synchronizing an audio track that is being recorded at a first location with a video track that is being recorded at a second location, such as on a flying UAV, is disclosed. First, the audio and video recorders being to record sound and video. Then, a GPS receive is used to pick up the very accurate GPS clock signal. A real-time clock is also used locally to generate a real-time value. At a predetermined time, the GPS time data is interrogated and a time-stamp is generated. A video encoder is then used to embed the time-stamp, either during recording, or shortly thereafter. A networked audio recording device records audio with a time stamp acquired from the network. These respective time-stamps are then used in post-processing to accurately synchronize the audio and video tracks.
