  • Patent number: 11272465
    Abstract: Methods and apparatus for synchronization of media playback within a wireless network. In one embodiment, the present disclosure is directed to precision synchronization over time, based on repeated measurements of a common time reference. In one exemplary embodiment, the common time reference is a Time Synchronization Function (TSF) of a Wireless Local Area Network (WLAN). In another exemplary embodiment of the present disclosure, the application processor and the modem processor measure a pulse width and the aforementioned common time reference in order to adjust media playback.

  • Patent number: 11039408
    Abstract: Methods and apparatus for synchronization of integrated circuits (ICs) within a wireless network. In one embodiment, a serial time protocol (STP) is disclosed for use within a wireless device of a wireless network. The disclosed STP provides a common protocol for communicating precision time information from one time-transmitter IC to another time-receiver IC within a wireless device. In one exemplary implementation, a time-transmitter and a time-receiver are implemented within the firmware of a wireless device. Various schemes utilizing the disclosed STP for time synchronization are also described.

  • Patent number: 10102175
    Abstract: Apparatus and methods for digital bus operation. In one embodiment, the digital bus is a bidirectional, time-division multiplexing (TDM) audio bus operation, and a bus technology is described that enables multi-drop (e.g., multiple device, multiple node, etc.) connectivity for real-time audio over a small form factor interface (e.g., as few as two (2) wires). Specifically, an exemplary tri-level signaling scheme provides bidirectional functionality, real-time clock edges, audio data, in a multi-drop topology in one implementation.
