Abstract :
Video transcoding, due to its high practical values for a wide range of networked video applications, has become an active research topic. We outline the technical issues and research results related to video transcoding. We also discuss techniques for reducing the complexity, and techniques for improving the video quality, by exploiting the information extracted from the input video bit stream.
