Abstract: In this paper,we describe an investigation exploring user experiences of accessing streamed multimedia content, when that content is tailored according to perceptual, device and location characteristics. To this end, we have created pre-defined transmission profiles and stream perceptually tailored multimedia content to three different locations, each characterised by different infotainment requirements. In the light of our results, we propose that multimedia transmission to mobile and wireless devices should be made based on pre-defined profiles, which contains a combination of static (perceptual, device type, CPU speed, and display specifications) and dynamic information (streamed content type location of the device/user, context of the device/user). The evaluation of such a system showed that the users and service providers can gain from such an approach considerably, as user perceptions of quality were not detrimentally affected by QoS degradations. Consequently, service providers can utilise this information to effectively manage local network traffic and bandwidth.
