Abstract

Techniques for generating utility-based descriptors (210) from compressed multimedia information are provided. A preferred method includes the steps of receiving (230) at 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 of the portions of utility based descriptor information to generate adapted multimedia segments, using a quality of management method to generate a quality 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.
