Algorithms for Cost-Effective Video Compression

By Angel Decegama Ph. D


Abstract — The volumes and costs of video storage and transmission are soaring. This situation can only be ameliorated by massive investments in infrastructure or by technological breakthroughs or both. This paper presents one such technological breakthrough that can reduce the size of any video file compressed by any existing video codec, e.g., MPEG-4, H.264, DivX, VC-1, etc., to between 25 % and 10 % of such compressed size without loss of the video quality resulting from the decompression and display by the codec of its compressed file and without any changes to the codec. The processing presented in this paper that achieves such results involves the preparation of the frames of the original video file before passing them on to a given codec. The codec then processes the received frames in its usual way t
