The existing sliding-block entropy compression coding with a fidelity criterion theorem is generalized to abstract source and source reproduction alphabets, stationary and ergodic sources and nonmetric distortion measures. This establishes the sliding-block entropy compression coding theorem in the same generality as the corresponding block entropy compression coding theorem.
