The increasing availability of distributed digital TV and multimedia (MM) resources - content and Web services - on the Web, raises the need to automatically retrieve and process resources to satisfy a given context. In order to fulfill a particular content need, usually a set of operations, realised through Web services, have to be orchestrated to retrieve and process, e.g. scale or transcode, MM content out of distributed repositories. However, the heterogeneities between concurrent MM metadata schemas and vocabularies raise issues with respect to interoperability. To overcome these issues, we propose the derivation of so-called Situation-driven Processes (SDP) for the digital TV domain. SDP are supported through a dedicated ontology, being aligned to the SWS reference ontology WSMO, and provide a means to semantically describe context-driven Web service orchestrations as being required for context-aware MM resource retrieval. Providing a specific SDP derivation for MM consumption contexts - being aligned to concurrent MM and TV metadata schemas and vocabularies - supports the automatic discovery of MM and TV resources while supporting interoperability across distinct MM and TV content repositories.
