摘要

AN AUDIO SIGNAL DECODER FOR PROVIDING AN UP MIX SIGNAL REPRESENTATION ON THE BASIS OF A DOWN MIX SIGNAL REPRESENTATION AND AN OBJECT-RELATED PARAMETRIC INFORMATION AND IN DEPENDENCE ON A RENDERING INFORMATION COMPRISES AN OBJECT PARAMETER DETERMINATOR. THE OBJECT PARAMETER DETERMINATOR IS CONFIGURED TO OBTAIN INTER-OBJECT-CORRELATION VALUES FOR A PLURALITY OF PAIRS OF AUDIO OBJECTS. THE OBJECT PARAMETER DETERMINATOR IS CONFIGURED TO EVALUATE A BIT STREAM SIGNALING PARAMETER IN ORDER TO DECIDE WHETHER TO EVALUATE INDIVIDUAL INTER-OBJECT-CORRELATION BIT STREAM PARAMETER VALUES TO OBTAIN INTER-OBJECT-CORRELATION VALUES FOR A PLURALITY OF PAIRS OF RELATED AUDIO OBJECTS, OR TO OBTAIN INTER-OBJECT-CORRELATION VALUES FOR A PLURALITY OF PAIRS OF RELATED AUDIO OBJECTS USING COMMON INTER-OBJECT-CORRELATION BIT STREAM PARAMETER VALUE. THE AUDIO SIGNAL DECODER ALSO COMPRISES A SIGNAL PROCESSOR CONFIGURED TO OBTAIN THE UP MIX SIGNAL REPRESENTATION ON THE BASIS OF THE DOWN MIX SIGNAL REPRESENTATION AND USING THE INTER-OBJECT-CORRELATION VALUES FOR A PLURALITY OF PAIRS OF RELATED OBJECTS AND THE RENDERING INFORMATION.
