Abstract:
A system for synchronizing a multimedia content stream signal, emanating from at least one multimedia source, for play through a plurality of output devices, wherein the output devices are connected to the multimedia source by wired connections and wireless connections; the system comprising:plural output realms, including wired realms and wireless realms; wherein said wired realms each include: a wired realm transceiver; a wired realm delay synchronizer, including a wired realm buffer for storing said multimedia content stream signal; an output device connected to said wired realm delay synchronizer; and a wired realm connection control processor (CTL) connected between said first wired realm transceiver and said wired realm delay synchronizer for exchanging medium access control (MAC) layer messages between said first wired realm transceiver and said wired realm delay synchronizer, and for determining a wired realm buffer delay for streaming the multimedia content stream signal from said wired realm buffer to an output device; and wherein said wireless realms each includes: a wireless realm transceiver; a wireless realm delay synchronizer; including a wireless realm buffer for storing said multimedia content stream signal; an output device connected to said wireless realm delay synchronizer and a wireless realm connection control processor (CTL) connected between said wireless realm transceiver and said wireless realm delay synchronizer for exchanging medium access control (MAC) layer messages between said wireless realm transceiver and said wireless realm delay synchronizer, and for determining a wireless realm buffer delay for streaming the multimedia content stream signal from said wireless realm buffer to an output device; and wherein said wireless realm buffer delay is transmitted to said wired realm CTL and wherein said wired realm buffer delay is transmitted to said wireless realm CTL.
