Abstract:
A method for synchronizing playback of a program including a video and associated first audio at a first electronic device with playback of a second audio associated with the program at a second electronic device that also receives the first audio, the method comprising: decoding, by a first audio decoder in the second electronic device, the first audio, and outputting the decoded first audio; decoding, by a second audio decoder in the second electronic device, the second audio and outputting the decoded second audio for playing back by the second electronic device; receiving a user command to synchronize the playback of the video at the first electronic device and playback of the second audio at the second electronic device; responsive to the user command, the method further comprising capturing, by a capturing device in the second electronic device, the playback of the first audio at the first electronic device; determining, by the second electronic device, an offset between the outputted decoded first audio and the captured first audio; and adjusting outputting of the decoded second audio according to the offset, so that the playback of the first audio at the first electronic device is synchronized with the playback of the second audio at the second electronic device.
