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

FIG. 7 illustrates a flow chart of an example of a method for seamless playback between wireless communications devices, implemented in accordance with some embodiments. As discussed above, wireless communications devices may be configured to seamlessly switch between wireless connection modalities to compensate for changes in distances and/or signal quality between the source and sink devices, thus ensuring seamless playback of the audio file despite such changes in distance. As will be discussed in greater detail below, a method, such as method 700, may be implemented to manage different wireless connections and facilitate the seamless switching between such wireless connections when appropriate.

Method 700 may commence with operation 702, during which a first wireless connection may be established. In various embodiments, the first wireless connection may be a wireless connection that is initially used to transmit data between devices, such as a source and a sink device. In one example, this may be a Bluetooth connection between a mobile device and a wireless headset, where the mobile device is streaming music to the wireless headset via the Bluetooth connection.

Method 700 may proceed to operation 704, during which a second wireless connection may be discovered. In various embodiments, the second wireless connection between the source and sink device may be discovered via one or more discovery operations. As discussed above, the second wireless connection may be a Wi-Fi connection. Moreover, during operation 704, the second wireless connection may be set to a power save mode.
