As an efficient way for archiving the existing video contents compressed by the old standard, we are developing a lossless re-encoding scheme for MPEG-1 video. In this paper, simplified probability models used for arithmetic coding of DCT coefficients are investigated to reduce computation time needed for our coding scheme.
