1. A method for delivering compressed multimedia information to one or more users, each having one or more resource constraints, comprising the steps of: (a) receiving at least a segment of said compressed multimedia information and a corresponding utility based descriptor; (b) parsing said utility based descriptor into two or more portions of descriptor information, each portion corresponding to a different one or more resource constraints; (c) for each of said one or more users, selecting one of said two or more utility based descriptor information portions, if any, which corresponds to said resource constraints for said user; (d) for each of said one or more users, adapting said received compressed multimedia segment by said selected utility based descriptor information portion; and (e) interpolating, for each of said one or more users for which one of said two or more utility based descriptor information portions were not selected in step (c), between two consecutive utility based descriptor information portions from said two or more utility based descriptor information portions to generate an interpolated utility based descriptor which approximately corresponds to said resource constraints for said user.
