Two-Dimensional Constrained Coding Based on Tiling

Abstract

A new variable-rate coding technique is presented for two-dimensional (2-D) constraints. For certain constraints, such as the (0, 2)-runlength-limited (RLL) and (3,¿)-RLL constraints, the technique is shown to improve on previously published lower bounds on the capacity of the constraint.
