Abstract
A method and device for synchronizing audio/video signals is provided. A first and a second auxiliary signal are generated, wherein the first and the second auxiliary signals are pulse-shaped, and transmitted to a first and a second rendering device via a first and a second transmission path, respectively. The first audio/video output signal based on the first auxiliary signal and a second audio/video output signal based on the second auxiliary signal are outputted to a user. The user adjusts a delay of the first and/or second transmission path by synchronizing the first audio/video output signal with the second audio/video output signal.
