ePAB: Energy-efficient, user-Preference based Adaptive multimedia Broadcast

Multimedia broadcast content reception process is energy-intensive. Use of mobile receiver devices with limited battery for such applications calls for reduced energy consumption. This paper presents ePAB - an energy-efficient user-Preference based Adaptive multimedia Broadcast scheme, that optimally clubs the user-preferences for a particular video quality profile, user device types, and the usage scenarios, for adaptive scalable video encoding of the broadcast content. User-preferences are obtained a priori via a subjective test questionnaire, that reflects the acceptance of the users towards a slightly lower video quality (good instead of excellent, and fair instead of good/excellent quality) in order to extend the receiver battery life. By incorporating the preference information in the video encoding, the proposed scheme helps achieve a higher energy saving as compared to the quality maximizing scheme aMultimedia broadcast content reception process is energy-intensive.
