Method and apparatus to obtain differential location information
First Claim
1. A method, comprising:
- determining, by a media recording device, a differential location sample identifying a current location in time associated with the media recording device relative to a reference location;
identifying initial velocity and acceleration data of the media recording device towards an indicated direction, wherein the initial velocity and acceleration data comprises x, y, and z axis values based on a pre-selected axis convention;
storing in an audio-visual media file the differential location sample expressed in terms of the identified initial velocity and acceleration data of the media recording device towards the indicated direction, wherein the initial velocity and acceleration data are determined from sensing using at least one of an accelerometer and an altitude sensor of the media recording device; and
transmitting, by the media recording device, the differential location sample in the audio-visual media file.
