  • Patent number: 9742820
    Abstract: Techniques for mitigating effects of differing latencies associated with real time data streams in multimedia communication networks. For example, a technique for mitigating a latency differential between a first media path and a second media path, over which a first device and a second device are able to communicate, includes the following steps. A training phase is performed to determine a latency differential between the first media path and the second media path. Prior to the first device switching a media stream, being communicated to the second device, from the first media path to the second media path, the first device synchronizes the media stream based on the determined latency differential such that a latency associated with the switched media stream is made to be substantially consistent with a latency of the second media path.
