Content-based utility function prediction for real-time MPEG-4 video transcoding

  title={Content-based utility function prediction for real-time MPEG-4 video transcoding},
  author={Yong Wang and Jae-Gon Kim and Shih-Fu Chang},
Utility function based transcoding is an efficient systematic solution for choosing optimal media transcoding operation to meet dynamic resource constraints (such as bandwidth). However, to date the real-time generation of utility function is not feasible due to computational complexity. In this paper we present a content-based utility function prediction framework for real-time MPEG-4 video transcoding. We develop a statistical approach combining real-time compressed-domain feature extraction… CONTINUE READING
