Abstract:
Systems and methods for video distribution synchronization are described herein. An example method to distribute a media stream over a distribution network to a number of devices may include determining, by one or more computer processors coupled to memory, a common master-client shared time reference Tref. Example methods may include determining a mean intermediate arrival time for first packets of a first type of the media stream, determining respective first playout times for the first packets based on the mean intermediate arrival time and the time reference Tref, associating the first packets with the respective first playout times, and distributing the media stream to the plurality of devices.
