Abstract
Video transcoding can convert a compressed video from one format to another format. In this paper, we propose a novel multiview video transcoder, which is used for bit-rate scaling of multiple compressed synchronized video streams. Different from the traditional joint transcoder for independent multiple program transcoding, the multiview video transcoder has one unique task to decorrelate spatial redundancies among video streams. A fast disparity estimation algorithm with the GOP-based disparity search window is put forward and evaluated. The proposed multiview video transcoder can be used to design a cost-effective video acquisition and transmission system for emerging 3D video applications.
