Abstract
Systems and methods for synchronizing video generated by a camera with media content generated by a media source external to the camera. A calibration procedure is performed in which a time delay is determined that includes a camera delay associated with the camera. A display device displays a sequence of images comprising a first image displayed for a first time period and a second image displayed for a second time period. The camera captures a plurality of captured images capturing display of the sequence of images and a transmitter device coupled to the camera transmits the captured images to a hub. The hub determines a target image of the captured images corresponding to display of the second image. The time delay is determined based on a difference between a time associated with the target image and a time associated with the second image.
