Speaker Synchronization Technique for Wireless Multichannel Sound Transmission System

摘要

The present invention relates to the transmission of sound data between a wireless sound transmitter for transmitting sound data received from a multimedia source and a wireless sound speaker for receiving sound data and outputting a sound signal. The present invention relates to a scheme for compensating a difference in playback time between wireless sound speakers generated when data is distributed and transmitted to a plurality of wireless sound speakers.;To this end, in the present invention, the TDMA-based multi-channel wireless transmission system receives a plurality of data having the same playback time information according to an input clock and stores the data in a corresponding memory, and sequentially repeats the stored data one by one according to the output clock. And a plurality of wireless sound speakers configured to receive and reproduce transmission packets received from the wireless sound transmitter and output the externally transmitted transmission packets modulating the output data through corresponding transmission channels.;TDMA, multichannel sound data, wireless sound transmitter, wireless sound speakers, time-difference compensation, null data
