    Abstract: The present specification relates to a method by which a source device transmits audio data in a short-range wireless communication system, and to an apparatus for same. The method proposed in the present specification comprises the steps of: establishing a connection with a sink device; performing a setup procedure for transmitting the audio data with the sink device on the basis of the established connection; and transmitting, to the sink device, the audio data on the basis of the setup procedure, wherein the steps of performing a setup procedure further comprises a step of transmitting, to the sink device, timing information on a transmission timing of the audio data and metadata information for transmission of the audio data, and the audio data is transmitted without transmission of a periodic advertisement message for transmitting the timing information and the metadata information.

    Abstract: The present disclosure relates to a method by which a third device transmits audio data in a short-range wireless communication system, and to an apparatus therefor. According to the present specification, the method by which a third device transmits audio data in a short-range wireless communication system comprises the steps of: transmitting, to at least one device, a first advertisement message for providing a broadcast audio data streaming service; transmitting, to the at least one device, a second advertisement message related to synchronization of an audio data output time point, wherein the second advertisement message includes force delay information for synchronizing a time point at which the audio data is output from each of the at least one device; and transmitting the audio data to the at least one device, wherein the time point at which the audio data is output from each of the at least one device is determined on the basis of the force delay information.
