MPEG-2 AAC is used in the following "real-world applications":
1) The Japanese Association of Radio Industries and Businesses (ARIB) has selected MPEG-2
AAC as the only audio coding scheme for all of Japan's digital broadcast systems,
including standard-definition television (SDTV), high-definition television (HDTV),
digital radio, and new multimedia services (mono, stereo, up to 5.1 channels) - for more
