摘要： In the present disclosure a method is proposed for switching from a first Bluetooth audio source to a second Bluetooth audio source in a user experience friendly manner, e.g. reducing latency. The method is performed by an audio rendering system comprising a primary wireless speaker and a secondary wireless speaker. The audio rendering system receives a first audio stream from the first audio source by using a first audio topology comprising a first set of wireless links. Upon receiving a request to switch to a second audio stream using a second audio topology, a second set of wireless links is established; and, the reception of the second audio stream starts while maintaining the audio rendering system and the first audio source connected by a wireless link of the first set of wireless links. The wireless speaker(s) can be a wireless earbud, a bookshelf speaker, a floor speaker, an outdoor speaker, a subwoofer, a headset speaker.

摘要： Audio rendering devices comprising at least one audio rendering unit for playing audio streams, processing circuit and a wireless communication unit for establishing wireless links and related method are disclosed. One audio rendering device is configured to receive a remote audio stream prioritization policy comprising one or more lists of associations between audio stream attributes and priority values, update a local audio stream prioritization policy based on the remote audio stream prioritization policy, identify audio streams available via wireless links, retrieve audio stream attributes of the available audio streams, select an available audio stream to be played among the available audio streams, based on the updated local audio stream prioritization policy and based on the audio stream attributes of the available audio streams, and play the selected audio stream, by the audio rendering unit of the audio rendering device.
