Error concealment of MPEG-2 AAC audio using modulo watermarks Conference Paper uri icon

abstract

  • We propose an error concealment scheme for MPEG-2 compressed (AAC) audio using a novel modulo watermarking technique. It can be used on top of other error control schemes. After the modulo watermark is embedded, an MPEG-2 AAC audio only shows negligible file size increase and moderate SNR penalty. For audio transmission over packet-switch networks (e.g., the Internet), using our watermark-based concealment scheme shows consistent SNR gain over using conventional concealment schemes.
