Abstract:
In DVD and SDMI one essential technique to protect intellectual property rights is
audio watermarking. The idea of audio watermarking is to perceptually hide
information in audio signals. In theory the watermark is totally inaudible and
does not impair the audio quality. This workshop analyses the problem of how to
evaluate the perceived quality of watermarked audio signals. After an
introduction to different applications of audio watermarking (also outside the
realm of conditional access) and the technology used to generate the
watermarking signals we will present examples how watermark and watermarked
signals sound like. A major part of the workshop will concentrate on the
methodology of testing high quality audio signals. Finally we will discuss the
issue of hostile attacks to the watermark and its influence on audio quality.
