Patent ID: 7412704

Claim:
A system for processing of media content, comprising: a processor to execute a development project means for loading one or more source processing chains to support execution of a development project, the source processing chains comprising a series of filters to process and render media content, wherein means for loading of the one or more processing chains comprises: means for identifying which source(s) will be required to support execution of the next M seconds of the development project, wherein M is at least as long as necessary to construct a processing chain; means for searching one or more cache(s) to determine whether the source processing chain(s) associated with the source(s) are available within the one or more cache(s); and means for retrieving the one or more processing chains from a memory location denoted by an associated one or more pointers in the cache for integration with the development project; and means for determining whether each of the one or more processing chains will be subsequently required during execution of this or another development project and, if so, means for caching those filter chains which will be subsequently required.
