Abstract

A method for managing video news segments using a media asset management system includes collecting the video news segments, associating corresponding geospatial data with each video news segment, and creating a search thesaurus including search descriptors with cross-references therebetween. At least one respective search descriptor from the search thesaurus is associated with each video news segment. The method further includes storing each video news segment, its geospatial data and its at least one search descriptor on the media asset management system for later search and retrieval, such as by a news broadcasting organization. The search descriptors may be geospatial search descriptors that are cross-referenced in a hierarchical relationship.
