Abstract: Audio streaming has become a popular application on the internet over the past few years, and is expected to grow with the advent of high-speed internet access. Content adaptability, copyright protection and Quality of Service (QoS) monitoring of these streams are some of the major issues encountered in audio streaming. While many studies have tackled the issue of audio watermarking for copyright protection, few have considered using watermarks for QoS monitoring and even fewer considered involving content adaptation at the same time. In this paper, we present a Universal Media Access (UMA) compliant transcoding module along with a watermarking-based module that provides copyright protection, data integrity and authenticity and QoS monitoring, all of which in an optionally private manner depending on the intended usage.

Keywords: audio watermarking; audio transcoding; audio copyright protection; audio QoS; quality of service; audio streaming; content protection; internet; content adaptability; data integrity; QoS monitoring; privacy; security.
