Abstract:
Apparatuses and methods for encoding/decoding scalable digital audio are disclosed. An apparatus for decoding scalable digital audio according to the present invention includes: an audio packet reception unit configured to receive a digital audio packet, including a plurality of pieces of direct audio channel data mapped to respective physical channels and a plurality of pieces of indirect audio channel data indirectly mapped to respective physical channels; an indirect audio channel extraction unit configured to extract the digital audio packet from the pieces of indirect audio channel data; an indirect audio channel decoding unit configured to generate pieces of audio channel data corresponding to a number of physical channels more than the number of pieces of indirect audio channel data using the pieces of indirect audio channel data; and an audio channel output unit configured to match the pieces of audio channel data to the respective physical channels and perform output.
