Optimization of MPEG-2 / MPEG-4 AAC for error prone transmission channels
MPEG Advanced Audio Coding (AAC) is the newest of the successful MPEG perceptual audio coding standards. While the basic algorithm was standardized as an extension to MPEG-2 in 1997, AAC recently has been substantially enhanced in MPEG-4. New features include additional coding tools for improved efficiency at very low bitrates, bitrate scalability extensions, and tools, which significantly enhance the performance over error prone transmission channels. The paper will report primarily on the work conducted to optimize AAC for environments with potentially high error rates, like 3G mobile networks.
