1. A method for streaming content in a wireless communication system, comprising:

  • receiving, at a sink device, timing information associated with a common timing source, wherein the timing information is based at least in part on a timing instance from a source device wireless communication layer, and captured by a source device multimedia layer, wherein the source device wireless communication layer is different from the source device multimedia layer;

    identifying, by the sink device, a composite timing delay associated with the common timing source based at least in part on an adjustment to a time of communication identified by a sink device wireless communication layer, and the timing information, wherein the adjustment is based at least in part on a timing of a sink device multimedia layer, and wherein the sink device wireless communication layer is different from the sink device multimedia layer;

    adjusting, by the sink device, a sink device timing based at least in part on the identified composite timing delay; and

    using, by the sink device, the adjusted sink device timing to synchronize presentation of the content streamed from the source device to a plurality of sink devices.
