A unified MC-DCT framework for reducing the computational complexity of frequency-domain transcoders for MPEG-2 video

Abstract

In order to transmit pre-encoded digital video over heterogeneous networks, it becomes necessary to employ transcoding techniques that convert pre-encoded video streams into streams having different bit rates and quality. Video transcoders save computational overheads incurred in the IDCT and DCT operations, by performing motion compensation (MC) in the… (More)
