A PRE-COMPENSATION TECHNIQUE FOR SYNCHRONIZATION BETWEEN WIRELESS SPEAKERS IN MULTICHANNEL WIRELESS SPEAKER SYSTEMS

摘要

PURPOSE: A pre-compensation technique for synchronizing between wireless speakers is provided to compensate reproduction time difference through a sound data delay in a transmission part. CONSTITUTION: A delay block(300) receives a plurality of data which has the same reproduction time information. The delay block outputs the received data by the set delay time length per each transmission channels. A modem unit is creates the transmission packet in which the outputted data is modulated. A communication unit transmits the modulated transmission packet through a transmission channel by the set transmission order.
