Abstract: PURPOSE: A multi-channel sound system for providing high quality sound and a wireless sound speaker which is included in the same are provided to correct sound data errors of the rearward wireless sound speaker, thereby providing high quality sound from the rearward wireless sound speaker. CONSTITUTION: A communication part is used in order to transmit and receive signals. A signal processing part distributes wireless sound signals during a time slot allocated for signal reception. The signal processing part extracts first sound data from a wireless signal received through the communication part from a transmission apparatus and outputs extracted data to a speaker. The signal processing part extracts second sound data from the wireless signal received through the communication part. The signal processing part transmits the extracted second sound data in the time slot allocated for signal transmission.

Abstract: 조정가능한 PT를가지는 AVB 기반의 SR 스피커시스템이제공된다. 본발명의실시예에따른 PT 조정방법은, 오디오수신장치들로부터오디오데이터의 TT들을수신하고, 수신된 TT들을이용하여오디오수신장치들의 PT를조정하며, 조정된 PT를오디오송신장치에전달한다. 이에의해, 스피커시스템에서 PT를조정가능하게되어, 스타디움이나콘서트장과같은넓은공간에서멀리위치한스피커들을 Daisy Chain 구조의네트워크로연결하는경우에도, 손실없이실시간으로오디오를스트리밍할 수있게된다.
