Processing method, system and related devices based on playing state information synchronization

The invention discloses a processing method based on playing state information synchronization. The method comprises the following steps: a synchronization server determines a playing state information reporting frequency parameter based on playing state information of each synchronization client and sends the playing state information reporting frequency parameter to each synchronization client; each synchronization client adjusts the reporting frequency based on the playing state information reporting frequency parameter and reports the playing state information to the synchronization server. The invention further discloses a processing system, the synchronization servers and the synchronization clients which are based on the playing state information synchronization. By adopting the technical scheme of the invention, the synchronization servers control the reporting frequency of playing state information of media grouped data for the synchronization clients according to the actual situation, and when the synchronization status is good, the synchronization clients need not to perform a synchronization flow on each media grouped datum, so that the cost and the communication data volume of synchronization processing can be reduced, and resources are saved.
