摘要： An external capability for measuring roundtrip latency in a conferencing system is provided. The external capability for measuring roundtrip latency in a communication system may include functions of generating a content event, detecting the content event in a received content stream including the content event, determine a first time associated with generation of the content event and a second time associated with detection of the content event, and computing a roundtrip latency based on a difference between the second time and the first time. The content event may be a visual event or an aural event. These functions may be implemented using one or more modules or elements. A computing device may be used to generate and detect the content event and to compute the roundtrip latency. Various other arrangements of modules or elements may be used to provide the functions.

摘要： In one aspect, a method for performing signal source localization is provided. The method comprises the steps of obtaining compressive measurements of an acoustic signal or other type of signal from respective ones of a plurality of sensors, processing the compressive measurements to determine time delays between arrivals of the signal at different ones of the sensors, and determining a location of a source of the signal based on differences between the time delays. The method may be implemented in a processing device that is configured to communicate with the plurality of sensors. In an illustrative embodiment, the compressive measurements are obtained from respective ones of only a designated subset of the sensors, and a non-compressive measurement is obtained from at least a given one of the sensors not in the designated subset, with the time delays between the arrivals of the signal at different ones of the sensors being determined based on the compressive measurements and the non-compressive measurement.
摘要翻译： 一方面，提供了一种执行信号源定位的方法。 该方法包括以下步骤：从多个传感器中的相应传感器获得声信号或其它类型的信号的压缩测量值，处理压缩测量值以确定在不同传感器处的信号到达之间的时间延迟，以及确定 基于时间延迟之间的差异的信号源的位置。 该方法可以在被配置为与多个传感器通信的处理设备中实现。 在说明性实施例中，压缩测量是从传感器的指定子集中的相应的测量值获得的，并且非压缩测量从至少一个不在指定子集中的传感器获得，其中时间延迟 基于压缩测量和非压缩测量确定不同传感器处的信号的到达。
