Abstract

Strategies for effectively discovering, selecting, configuring, and controlling components used in media processing applications are described. According to one exemplary implementation, the strategies described configure the components based on profile information, configuration information, and a hierarchical ordering of configuration parameters. The hierarchical ordering may combine different coding paradigms, where one or more high level nodes in the ordering may define configuration parameters which are common to multiple coding paradigms. In this ordering, selection of a configuration parameter may cascade down to affect lower-ranking dependent parameters in the hierarchical ordering. According to one advantage, the hierarchical ordering provides a more uniform, extensible, and problem-free approach to configuring components than unstructured approaches to configuration. Moreover, applications can utilize the hierarchical ordering at different levels of granularity.
