Abstract
Methods, systems, and apparatuses are described for performing a calibration process for synchronizing audio signals with video signals. The calibration process may be performed between one or more devices of an entertainment system and a handheld device. Device(s) (e.g., a television and speaker(s)) of the entertainment system are configured to playback video signal(s) and audio signal(s), respectively. The handheld device is configured to determine an amount of synchronization error between the audio signal and the video signal, determine a synchronization correction value based on the determined amount, and provide the synchronization correction value to device(s) of the entertainment system. The device(s) may use the synchronization correction value to correct the delay between the video signal and the audio signal such that the video signal and the audio signal are synchronized.
