Intention-aware multimedia modeling for optimized Quality of Experience

Abstract

Multimedia Quality of Experience (QoE) is not only a matter of Quality of Service (QoS). Network-based metrics such as delay, jitter or packet loss ratio are critical indicators for multimedia services; nevertheless, we believe that considering the expectations of all the parties in a communication scenario can help improving the overall QoE. Through the empirical examples of radio and movies production, we show that the form of a multimedia object must serve its content, i.e. the author(s)' intentionality. We propose an intention-aware multimedia model which explicitly distinguishes form and content to grant robustness and flexibility to multimedia communications, persisting the producer(s)' intention while adapting it to the consumer(s)' context. Finally, this approach is studied in an immersive video-conferencing use case.Index Terms-immersive communication, multimedia, quality of experience, quality of service

Quality of Protection and Quality of Experience in Multimedia Communications

“…Quality of service (QoS) is closely related to the quality of experience, both of them describe service quality but from different views. Table 1 illustrates the differences between QoE and QoS. QoS metrics such as packet loss, delay and delay variation (jitter) directly affect QoE [5]. Researchers should plan for subjective test correctly, they should prepare test environment, setting up hardware and software that is needed in the test according to the type of multimedia in evaluation, for video streaming, many factors such as room illumination, display brightness and ratio of the luminance of the screen should be considered whether the experiment will be in lab or at home.…”
