METHOD OF WIRELESS AUDIO TRANSMISSION AND PLAYBACK
First Claim
1. A method of wireless audio transmission and playback, to be implemented by a system which includes a host and a plurality of audio playback devices, the host storing audio data and being capable of communicating with each of the audio playback devices via wireless communication, the method comprising steps of:
- a) dividing, by the host, the audio data into a plurality of audio segments;
b) transmitting, by the host, the plurality of audio segments to each of the audio playback devices;
c) transmitting to the host, by each of the audio playback devices, with respect to each of the audio segments received thereby, an acknowledgment which corresponds to the audio segment and which indicates that the audio playback device has received the audio segment; and
d) when it is determined by the host based on the acknowledgment(s) thus received that at least one of the audio playback devices has received a first specific audio segment which is indicated by one of the acknowledgement(s) as the audio segment received by said at least one of the audio playback devices, controlling, by the host, all of the audio playback devices that have received the first specific audio segment to play the first specific audio segment synchronously with each other.
