WIRELESS AUDIO TRANSMISSION DEVICE, WIRELESS SOUND OUTPUT DEVICE, AND SYSTEM HAVING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18026306 titled 'WIRELESS AUDIO TRANSMISSION DEVICE, WIRELESS SOUND OUTPUT DEVICE, AND SYSTEM HAVING SAME

Simplified Explanation

- The present invention is about a wireless audio transmission device and a wireless sound output device, along with a system that includes both. - The wireless audio transmission device has a communication unit for wirelessly transmitting an audio signal to multiple wireless sound output devices. - It also has a processor that controls the communication unit. - In the access point mode of the wireless audio transmission device and the station mode of the wireless sound output devices, a synchronization request message is wirelessly transmitted to the sound output devices, and a synchronization response message is received from at least one of them. - After receiving the synchronization response message, when the wireless audio transmission device is in the station mode and a specific wireless sound output device is in the access point mode, a second synchronization request message is received from the sound output device, and a second synchronization response message is transmitted wirelessly. - The purpose of this invention is to reduce synchronization errors in a wireless sound output system.


Original Abstract Submitted

The present invention relates to a wireless audio transmission device, a wireless sound output device, and a system having same. A wireless audio transmission device according to one embodiment of the present invention comprises: a communication unit for wirelessly transmitting an audio signal to a plurality of wireless sound output devices; and a processor for controlling the communication unit, wherein, when the wireless audio transmission device is in an access point mode and the plurality of wireless sound output devices are in a station mode, the communication unit wirelessly transmits a synchronization request message to the plurality of wireless sound output devices and wirelessly receives a synchronization response message from at least one of the plurality of wireless sound output devices; and after receiving the synchronization response message, when the wireless audio transmission device is in the station mode and a first wireless sound output device among the plurality of wireless sound output devices is in the access point mode, the communication unit wirelessly receives a second synchronization request message from the first wireless sound output device, and wirelessly transmits a second synchronization response message from the first wireless sound output device. Accordingly, it is possible to reduce a synchronization error in a wireless sound output system.
