Abstract
Techniques for broadcasting audio data from one device to multiple devices are described. A sound source device is configured for broadcasting audio data on a plurality of first time blocks in a first broadcast interval, and, one or more receiving and forwarding devices are configured for receiving the audio data from the sound source device and/or other receiving and forwarding devices on one or more second time blocks in a second broadcast interval, where the receiving and forwarding devices forward the audio data on one or more third time blocks in the second broadcast interval after the audio data packet is received correctly. The first broadcast interval is synchronously aligned with the second broadcast interval, and the aligned first and second broadcast intervals are used to transmit the same audio data. Thereby, reliable audio data communication from one point to multiple points can be realized.
