摘要

Systems, methods, and devices seamlessly playback data files using one or more wireless connections. Methods include establishing a first wireless connection between a source device and a sink device, the first wireless connection using a first transmission protocol and transmitting audio data via the first wireless connection. Methods further include determining a switch should be initiated based on one or more signal quality metrics, the one or more signal quality metrics representing, at least in part, an estimate of a quality of the first wireless connection. Methods also include switching to a second wireless connection between the source device and the sink device, the second wireless connection using a second transmission protocol, and the second wireless connection using data packets encapsulated for transmission in accordance with the second transmission protocol.

說明書

Method 800 may proceed to operation 810 during which data may be streamed using the first wireless connection. Accordingly, during operation 810, one or more components of the source device may cause the transmission of data over the first wireless connection. For example, an application executed on a mobile device may cause the transmission and streaming of an audio file so that it may be played by the sink device. The streamed data is transmitted from the source device to the sink device as a data stream that is packetized in accordance with the transmission protocol of the first wireless connection. It will be appreciated that the source and sink device may be any suitable Bluetooth-capable source and sink devices.

Method 800 may proceed to operation 812 during which the one or more signal quality metrics may be monitored. Accordingly, one or more of the devices, such as the source device, may periodically measure and/or compute the one or more signal quality metrics. Moreover, the monitored metrics may be stored in a memory device.
