Multimedia contents adaptation by modality conversion with user preference in wireless network

The rapid evolution in the hardare sector has brought up various media end user devices like PDAs or smart phones on hich online multimedia content can be consumed. Due to different capabilities of these devices as ell as individual user preferences, the original multimedia resources have to be adapted in order to fit the specific devices' constraints and to meet the user's requirements. Adapting multimedia content through user preferences is an important aspect of Quality of Service (QoS). There has been a vast amount of activities in research and standard development in this area. In this paper, e present methods for adapting multimedia contents to accommodate user preference. In addition, e propose the user preference content value model (u-CVM) that relates the content value of different modalities ith resources. Experiments demonstrate that modality conversion brings a ider range of adaptation for QoS support. Moreover, the proposed approach has to be effective to be applied in Digital Multimedia Broadcasting (DMB) and Telematics.
