Patent ID: 6959438

Claim:
A system comprising: a plurality of sources; and an interface, selectively coupled to the plurality of sources, to generate and implement a media processing development project of processing chains at least one chain of which comprises multiple filters, wherein the interface loads a processing chain for each of the plurality of media sources at a point during the execution of the project when the chain is required, and wherein the interface is configured to unload at least a subset of the chains when they are not required, wherein unloading of said subset is accomplished based, at least in part, on a generated execution list comprising: a chain identifier field which maintains a list of chains utilized in the project; a source identifier field which contains information denoting a project source; a project time field which denotes at what point during the project execution of a source chain is required; a source time field which denotes what portion of a source file is required; and a dependencies field which denotes whether an associated chain is dependent on any other chains.
