METHOD AND APPARATUS FOR PROCESSING A MEDIA SIGNAL

摘要

An apparatus for processing a media signal and method thereof are disclosed, by which the media signal can be converted to a surround signal a surround signal by using spatial information of the media signal. The present invention provides a method of processing a signal, the method comprising of generating source mapping information corresponding to each source of multi-sources by using spatial information indicating features between the multi-sources; generating at least one rendering information by using the source mapping information and filter information having a surround effect; and performing interpolation by using neighbor rendering information of the at least one rendering information.
