| Abstract: | Video transcoding has realized the transmission of video data between the heterogenous networks and different clients effectively, and it also guarantees the quality of video service. In this paper, various video transcoding techniques are analyzed thoroughly, including bitrate transcoding, resolution transeoding, standards transcoding, information insertion transcoding, objectbased video transcoding, joint transcoding and their architectures and primary algorithms. The paper has also discussed the development of research in video transcoding. |
