Abstract
In a network of interconnected multimedia source, transfer, and sink ports, the described subject matter defers port parameter selection until substantially all relevant information is available. Specifically, parameters are negotiated between multiple ports by specifying parameter sets corresponding to the ports. Each parameter set is expressed as a list of constraints on allowable values or ranges of values. When connecting multiple ports, the constraints on their parameter sets are conjoined to form a parameter set intersection. The parameter sets of the ports are limited to values included in the parameter set intersection. Parameter sets relating to other ports are potentially limited based on the intersection results. The conjoining and limiting operations are repeated until the various parameter sets exhibit no further limitations in response to further repetitions. This process is repeated for all port interconnections. Subsequently, values for the port parameters are selected from the limited parameter sets.
