    摘要: Techniques for generating utility-based descriptors from compressed multimedia information are disclosed. A preferred method includes the steps of receiving least a segment of compressed multimedia information, determining two or more portions of utility based descriptor information based on one or more adaptation operations, each corresponding to a unique target rate, adapting the compressed multimedia segment by each the portions of utility based descriptor information to generate adapted multimedia segments, using a quality management method to generate measurement for each adapted multimedia segment, and generating a utility based descriptors based on the portions of utility based descriptor information and corresponding quality measurements.

    摘要: Disclosed is a system for authoring metadata that describe multimedia contents. A storage device loads information on a currently edited metadata document so as to describe multimedia contents, and a metadata editor visualizes the loaded metadata document according to a predetermined method, and allows a user to edit the metadata document. A multimedia access reproducer accesses the input multimedia contents to reproduce corresponding multimedia contents, and an inter-media metadata interface links the multimedia access reproducer and the metadata editor to browse contents and effectively edit information relating to a specific interval of multimedia contents. A metadata output device outputs information on the loaded metadata document according to a predefined format.
