In 1977, Wen-Hsiung Chen developed a fast DCT algorithm with C.H. Smith and S.C. Fralick.[15] In 1979, Anil K. Jain and Jaswant R. Jain further developed motion-compensated DCT video compression,[16][3] also called block motion compensation.[7] This led to Chen developing a practical video compression algorithm, called motion-compensated DCT or adaptive scene coding, in 1981.[7] Motion-compensated DCT later became the standard coding technique for video compression from the late 1980s onwards.[17][2]
