Method and system for disaggregating audio/visual components

A system for disaggregating audio-visual systems comprising:

• a first and a second brick;
• an audio-visual source device;
• and
• one or more audio-visual output devices;
• wherein said audio-visual source device generates an audio-video stream having a time stamp and a maximum propagation delay indication appended thereto and is coupled to an at least partially non-isochronous network via said first brick, said maximum propagation delay indication representing a predetermined transmission time of said audio-video stream;
• wherein said one or more output devices are connected to said at least partially non-isochronous network via said second brick, for receiving said audio-video stream and obtaining said time stamp and said maximum propagation delay indication therefrom, synchronizing said audio-video stream based on an aggregation of said maximum propagation delay indication and said time stamp, and rendering said audio-video stream from said audio-video source device based on the synchronizing;
• and
• wherein said first and second brick provide protocol conversion through a network interface component and an analog audio-visual component.

A system for disaggregating audio-visual systems comprising:

• wherein said brick provides protocol conversion through a network interface component and an analog audio-visual component.

A method in a computing environment for synchronizing the rendering of a portion of an audio-visual stream from a source device on one or more output devices comprising:

• identifying on an at least partially non-isochronous distribution network, a time master;
• providing to said source device and the one or more output devices at least one time component, said time component corresponding to information obtained from said time master;
• providing to said one or more output devices a maximum propagation delay indication, said maximum propagation delay indication representing a predetermined transmission time of said portion of said audio-visual stream;
• and
• utilizing said time component and said maximum propagation delay indication on said one or more output devices, to establish a common time rendering said portion of said audio-visual stream synchronously.

A computer system having a processor, a memory and an operating environment, the computer system operable to execute a method for synchronizing the rendering of a portion of an audio-visual stream from a source device on one or more output devices, the method comprising:

• identifying on an at least partially non-isochronous distribution network, a time master;
• providing to said source device and the one or more output devices at least one time component, said time component corresponding to information obtained from said time master;
• providing to said one or more output devices a maximum propagation delay indication, said maximum propagation delay indication representing a predetermined transmission time of said portion of said audio-visual stream;
• and
• utilizing said time component and said maximum propagation delay indication on said one or more output devices, to establish a common time rendering said portion of said audio-visual stream synchronously.

One or more computer-readable media having computer executable instructions for performing a method for disaggregating audio-visual systems, the method comprising:

• providing an audio-visual stream from a source device as one or more data packets for communication over a non-isochronous link of a network;
• transmitting said one or more data packets over said non-isochronous link of said network, each of said one or more data packets having a time stamp and a maximum propagation delay indication appended thereto, said maximum propagation delay indication representing a predetermined transmission time of said one or more data packets;
• receiving said one or more data packets at multiple output devices and obtaining a time stamp, and a maximum propagation delay indication from each of the one or more received data packets;
• and
• rendering each of said one or more data packets on multiple output devices in a synchronized fashion, wherein the synchronized fashion is based on an aggregation of said obtained maximum propagation delay indication and said obtained time stamp for each data packet.
