Abstract
Disclosed herein is a method of sending and receiving (or transceiving) audio stream in a wireless communication system. The method performed by a first device includes receiving reference codec information from a second device, performing an audio codec negotiation procedure for determining an audio codec to be used to send and receive audio stream to and from a third device, checking whether the audio codec determined through the audio codec negotiation procedure is identical with the audio codec supportable by the second device, and operating in bypass mode or conversion mode based on a result of the check.
Claims16
A method of transceiving audio stream in a wireless communication system, the method performed by a first device comprising:
- receiving reference codec information from a second device, the reference codec information comprising audio codec type information indicating an audio codec type supported by the second device, the reference codec information being included in an advertising channel PDU (Packet Data Unit) or a data channel PDU;
- performing an audio codec negotiation procedure for determining an audio codec type to be used to transceive the audio stream to and from a third device;
- checking whether the audio codec type determined through the audio codec negotiation procedure is identical with the audio codec type supported by the second device;
- and
- operating in bypass mode or conversion mode based on a result of the check,
- wherein the bypass mode or the conversion mode is determined according to whether or not an audio codec conversion of the audio stream is performed.
A first device for transceiving audio stream in a wireless communication system, the first device comprising:
- a communication unit configured to perform communication in a wireless or wired manner;
- and
- a processor functionally connected to the communication unit, wherein the processor performs control the first device to:
- receive reference codec information from a second device, the reference codec information comprising audio codec type information indicating an audio codec type supported by the second device, the reference codec information being included in an advertising channel PDU (Packet Data Unit) or a data channel PDU;
- perform an audio codec negotiation procedure for determining an audio codec type to be used to transceive the audio stream to and from a third device;
- check whether the audio codec type determined through the audio codec negotiation procedure is identical with the audio codec type supported by the second device;
- and
- operate in bypass mode or conversion mode based on a result of the check,
- wherein the bypass mode or the conversion mode is determined according to whether or not an audio codec conversion of the audio stream is performed.
