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.

As similarly discussed above, a designated distance, such as distance 230, may identify an effective range of a particular communications modality. Accordingly, in the example shown in FIG. 2, source 210 may be outside a range for Bluetooth communication, but may still be within Wi-Fi range. Moreover, source 208 may be within a range for both Bluetooth and Wi-Fi communication. As also noted above, the position of the sources may change. Accordingly, system 200 is configured to identify such changes, and seamlessly switch between communications modalities in response to identifying such changes. Moreover, as also similarly discussed above, while FIG. 2 shows sources 210 and 208, it will be appreciated that system 200 may be implemented with only source 210 or only source 208. Additional details regarding such determinations and seamless switching are discussed in greater detail below.
