Summary:The present invention relates to sound data transmission between a wireless sound transmitter that transmits sound data received from a multimedia source, and a wireless sound speaker that outputs sound signal by receiving the sound data, and more particularly, to a method for compensation of a play time delay between the wireless sound speakers occurring when the multichannel sound data is distributed and transmitted from the wireless sound transmitter to the multiple wireless sound speakers. The differences in the play time points occurring between the speakers in a TDMA based multichannel wireless transmission system, are pre-compensated through the delay of the sound data in the WSDT.
