Abstract:
1. A method of audio synchronization on a home network, comprising: sending digital audio streams to two or more receiver devices, said digital audio streams including a control code to a specific one of the two or more receiver devices; outputting sound wave signals from two or more receiver devices on the home network; recording a first time difference between a first time of sending a control code to the specific one of the two or more receiver devices and a second time the sound wave signal is received from the specific one of the two or more receiver devices; recording a second time difference between a third time of sending a control code to an other specific one of the two or more receiver devices and a fourth time the sound wave signal is received from the other one of the two or more receiver devices; and automatically adjusting a relative delay of the sound wave signals outputted from the specific one of the two or more receiver devices; wherein the relative delay is adjusted by buffering the digital audio stream received in the specific one of the two or more receiver devices.
