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.

11. An unmanned aerial vehicle (UAV) configured to generate video recordings synchronized with an absolute time reference, the UAV comprising:
-
a camera; a Global Positioning System (GPS) receiver; a real-time clock configured to receive GPS time information from the GPS receiver; a video encoder configured to generate video recordings including at least one time stamp received from the real-time clock and synchronized with an absolute time reference.

12. A method for synchronizing an audio track recorded at a first location with a video track recorded at a second location, said method comprising the steps of:
-
activating said audio recording at said first location and said video recording at said second location; using a GPS to generate location data and a GPS time-stamp, based on satellite triangulation and a system-wide GPS clock signal; using an electronic clock to generate a real-time value; triggering said real-time generator; extracting time data from said GPS receiver at a first predetermined time, in response to said real-time generator being triggered; encoding said time data onto one of said audio track and said video track at a second predetermined time; and referencing said encoded time data to synchronize said audio track with said video track. - View Dependent Claims (13, 14, 15, 16, 17)
