11. A video producing system, comprising:
a video output screen, producing video and sounds associated with the video, a communication device, a processing device, that receives a communication from an external device that represents a difference between times of video, and sounds associated with the video, and responsive to said communication automatically adjusting a time between the producing of the video and the producing of the sounds, to adjust the time between audio and video in a first way when the audio plays before the video, and to adjust the audio and video in a second way when the video plays before the audio. - View Dependent Claims (12, 13, 14)
