    摘要： A system and method for adaptation of time synchronization of a plurality of multimedia streams is presented. In one embodiment, multimedia data is captured, via a plurality of multimedia platforms. A first synchronization signal is received by each of the plurality of multimedia platforms. The first synchronization signal is used to generate a first common clock reference among the plurality of multimedia platforms. Captured multimedia data is synchronized according to the first common clock reference. A second synchronization signal is received by each of the plurality of multimedia platforms. The second synchronization signal is used generate a transitional common clock reference among the plurality of multimedia platforms. The second synchronization signal is also used to generate a second common clock reference among the plurality of multimedia platforms.

    摘要： A method, machine readable medium, and system are disclosed. In one embodiment the method comprises generating an acoustic signal from an actuator of a first computing device, receiving the acoustic signal with a sensor of a second computing device, receiving the acoustic signal with a sensor of a third computing device, generating an estimate of a difference between the amount of time required for the acoustic signal to travel from the actuator of the first computing device to the sensor of the second computing device and the amount of time required for the acoustic signal to travel from the actuator of the first computing device to the sensor of the third computing device, wherein the sensors and actuator are unsynchronized, and computing, based on the estimated difference in time, a physical location of at least one of the said sensors and actuator.

    摘要： According to one embodiment of the present invention, a novel method and system are disclosed. In one embodiment, a first node records a first node local time of receiving a wirelessly transmitted packet, the first node local time recorded with a monotonically increasing clock of the first node. The first node wirelessly transmits the recorded local time to at least a second node. The second node records a second node local time of receiving the wirelessly transmitted packet and records the first node local time of receiving the wirelessly transmitted packet. The second node updates a second node timing model to synchronize with the first node, the updating based on the second node local time of receiving the wirelessly transmitted packet and the first node local time of receiving the wirelessly transmitted packet. In one embodiment, the method and system further include synchronizing sample numbers of a multimedia stream on the second node with the timing model of the second node, the timing model of the second node having been synchronized with the first node.
