Abstract:
(EN) An electronic device is disclosed. The electronic device can comprise: a processor; a communication module for setting a wireless link with an output device; and a transmission buffer for storing an audio packet to be transferred to the output device through the wireless link. The processor can be set such that the communication module: transfers, to the output device, the audio packet having been encoded at a first bit rate and stored in the transmission buffer; stores, in the transmission buffer, the audio packet having been encoded at a second bit rate, which is lower than the first bit rate, when the state of the transmission buffer does not satisfy a critical condition; and transfers, to the output device, the audio packet having been encoded at the second bit rate.
(FR) L'invention concerne un dispositif électronique. Le dispositif électronique peut comprendre : un processeur ; un module de communication permettant d'établir une liaison sans fil avec un dispositif de sortie ; et un tampon de transmission permettant de stocker un paquet audio à transférer au dispositif de sortie par l'intermédiaire de la liaison sans fil. Le processeur peut être réglé de telle sorte que le module de communication : transfère, au dispositif de sortie, le paquet audio ayant été codé à un premier débit binaire et stocké dans le tampon de transmission ; stocke, dans le tampon de transmission, le paquet audio ayant été codé à un second débit binaire, qui est inférieur au premier débit binaire, lorsque l'état du tampon de transmission ne satisfait pas à une condition critique ; et transfère, au dispositif de sortie, le paquet audio ayant été codé au second débit binaire.
(KO) 전자 장치가 개시된다. 상기 전자 장치는, 프로세서, 출력 장치와 무선 연결(wireless link)을 설정하는 통신 모듈, 및 상기 무선 연결을 통해 상기 출력 장치로 전달될 오디오 패킷이 저장되는 전송 버퍼를 포함할 수 있다. 상기 프로세서는, 상기 통신 모듈이 상기 전송 버퍼에 저장된 제1 비트 레이트(bit rate)로 인코딩된 오디오 패킷을 상기 출력 장치로 전달하도록 하고, 상기 전송 버퍼의 상태가 임계 조건을 만족하지 못하면, 상기 제1 비트 레이트보다 낮은 제2 비트 레이트로 인코딩된 오디오 패킷을 상기 전송 버퍼에 저장하고, 상기 통신 모듈이 상기 제2 비트 레이트로 인코딩된 오디오 패킷을 상기 출력 장치로 전달하도록 설정될 수 있다.
