Abstract

This paper describes an error resilient source coding approach for variable length codes. The presented algorithm has been designed to make the Huffman coded spectral data of MPEG-2/4 Advanced Audio Coding (AAC) more resilient against transmission errors. It has become part of ISO/IEC 14496-3/AMD 1 (MPEG-4 Audio Version 2). With this approach, the perceptual audio quality can be significantly increased in the presence of adverse channel conditions as they appear in the case of wireless transmission applications. New subjective test results are presented based on the MUSHRA test method.:
