Abstract
A media system, method, and a computer program product for synchronizing device clocks including a plurality of devices having device clocks, where each device is capable of independently selecting a primary clock device from the plurality of devices to coordinate clock synchronization of the remaining devices, e.g., secondary devices. Each device can utilize the same criteria or set of rules to select the primary clock device from among the plurality of devices after an initial exchange of data during a discovery phase. The selection of the primary clock device can be based on random or arbitrary selection, or based on at least one devices characteristic exchanged within the data obtained during the discovery phase. Once selected, the primary clock device coordinates a clock synchronization sequence with each secondary device until each secondary device clock is synchronized to within a predetermined threshold with the primary clock of the primary clock device.
