Abstract:
1. A method of coordinating audio reproduction for heterogeneous end devices in heterogeneous first and second networks, the method comprising: receiving an audio signal from one of the heterogeneous end devices in the heterogeneous first and second networks; associating, at at least one controller, a first timestamp with a first audio stream and a second timestamp with a second audio stream, the first and second timestamps being different, each of the first and second audio streams containing audio information of the received audio signal; and sending the first audio stream to a first end device in the first network and the second audio stream to a second end device in the second network, the first and second timestamps providing timing information such that the audio signal is reproducible by the first and second end devices at a substantially simultaneous time, wherein the first timestamp is used by the first end device to reproduce the first audio stream or by a first communication device serving the first end device to provide the first audio stream for reproduction by the first end device, and wherein the second timestamp is used by the second end device to reproduce the second audio stream or by a second communication device serving the second end device to provide the second audio stream for reproduction by the second end device.
