Abstract

Multimedia communication has gained an increasing interest in the last decade. The design of services and distributed multimedia applications imposes a number of Quality of Service (QoS) requirements. In particular, the processing and delivery of multimedia content are not independent and their interaction has a major impact on the QoS aspects. Recently, tracing watermarking has been introduced as a blind method for evaluating the QoS of multimedia communications. This paper aims at presenting a review of recent patents, and state of art solutions as well, in the field of QoS assessment of multimedia communication by tracing watermarking. Finally, a discussion pointing out the current and future developments in this area summarizes the remarkable points of this work.

Keywords: Data networks, digital watermarking, 3G multimedia communications, quality of service (QoS), QoS assessment.
