Two universal lossy data compression schemes, one with fixed rate and the other with fixed distortion, are presented, based on the well-known Lempel-Ziv algorithm. In the case of fixed rate R, the universal lossy data compression scheme works as follows: first pick a codebook Bn consisting of all reproduction sequences of length n whose Lempel-Ziv codeword length is ⩽nR, and then use Bn to encode the entire source sequence n-block by n-block. This fixed-rate data compression scheme is universal in the sense that for any stationary, ergodic source or for any individual sequence, the sample distortion performance as n→∞ is given almost surely by the distortion rate function. A similar result is shown in the context of fixed distortion lossy source coding
