An apparatus for processing a media signal and method thereof are disclosed, by which the media signal can be converted to 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 extracting spatial information and a downmix signal from a bitstream; and generating rendering information by using the spatial information and filter information having a surround effect, wherein the rendering information comprises first rendering information applied to one channel of the downmix signal extracted from the bitstream and then transmitted on the same channel and second rendering information applied to the channel and then transmitted on another channel.
