METHOD AND APPARATUS FOR DECODING A SIGNAL

摘要

A method and an apparatus for decoding a signal are provided to consider control information and/or device information when converting an object parameter, thereby variously changing a virtual location of a listener or a virtual location of a source and generating an output signal suitable for the number of outputable channels. An object parameter receiver(212) receives an object parameter. An object parameter extractor(120) extracts object information by parsing the object parameter. A control parameter generator(220) generates a control parameter by using the object information and control information including at least one of user control information, default control information, device control information and device information. A rendering parameter generator(230) generates a rendering parameter for determining a location and a level of an object in an output signal by using the object parameter and the control parameter.
