7 May 2003 Rate-distortion models for video transcoding
Author Affiliations +
This paper addresses the problem of selecting a single transcoding method from multiple transcoding possibilities that satisfy a specified delivery constraint. We first discus the rate-distortion modeling of DCT coefficients. Then, we quantify the distortion of the video transcoding output by examining the rate-distortion relationship of the popular transcoding techniques, including requantization, spatial downsampling and temporal downsampling. The use of our model is illustrated in some typical applications.
