TECHNICAL FIELD

[0001] The present application relates to the technical field of audio data processing, in particular to a streaming media resource transceiving box. BACKGROUND

[0002] Wireless streaming media technology mainly uses wireless communication technology (for example, WiFi) to wirelessly transmit media content such as audio, video, and photos from a source device to a target device supporting a streaming media protocol, such as a sound box, a TV, or a smart sound box, etc. through a cloud (or a cloud server). At present, in order to receive streaming media, one implementation scheme is to use a smart phone or the like as a transfer device, that is, to use a smart phone or the like as a transfer device to obtain music and other streaming media resources from the cloud, and then forward them to the target device for playing. Another implementation scheme is that the target device directly obtains music and other streaming media resources from the cloud through a WiFi module.

[0003] For the first implementation scheme, the defect is that when there is other input information (for example, the smart phone answers a call), the transmission of the streaming media resources will be interrupted, and the second implementation scheme requires the target device to support the WiFi protocol, which cannot be implemented for some devices that do not support the WiFi protocol.
