Abstract
Methods and systems provide control of media synchronization using time stamp pairs. In an embodiment, a first device may request a time stamp from a second device. The first device may determine any de-synchronization between the first and second devices based on the requested time stamp and characteristics of the request. The first device may define a rate scalar based on the determined de-synchronization. A sample rate conversion may be performed for the first device based on the rate scalar such that the outputs of the first device and the second device are synchronized.
