a plurality of processing resources configured to perform one or more processing operations on said input streams;

a resource monitoring engine configured to determine the load of said processing resources and generate resource utilization data;

an attribution module configured to query and receive said resource utilization data, to receive processing operation instructions, and said stream payload detection, to generate a routing command perform a suitability analysis from at least one of said resource utilization data, processing operation instructions, and payload analysis, and to assign said one or more processing resources to said one or more streams in accordance with said resource utilization data; and

,

a dispatching module configured to receive said routing command and to distribute said one or more streams in said input module to said one or more processing resources in accordance with said routing command.

8. The system defined in claim 7, further comprising an output module configured to receive or collect data resulting from said plurality of processing resources, to produce one or more processed media streams by aggregating data and metadata received from one or more said processing resources, and to make said processed media streams available for further use.

9. The system defined in claim 7, wherein said attribution module is configured to monitor the content of said stream input for purposes of truncating or reassigning, among any one or more said processing resources and in accordance with stream protocol requirements, any divisible portion of any one or more previously issued routing commands for which processing operations have not yet completed, by generating an amended routing command.

10. The system defined in claim 9, wherein said dispatching module is configured to receive said amended routing command and redistribute said one or more processing resources in accordance with said amended routing command.

11. The system defined in claim 7, wherein at least one of said processing resources is a specialized electronic circuit configured to rapidly manipulate image or other metadata associated to said stream inputs.

12. The system defined in claim 11, wherein said circuit is a GPU.

13. The system defined in claim 12, wherein said metadata comprises information used to identify, describe, or classify part or all of any one or more said stream inputs.
