Abstract
A computer-readable medium includes computer-executable instruction for compressing data to form a compressed data stream for a restricted channel. Specifically, data is compressed to form code values and character values, and a mask is created that indicates the location of these code values and character values in the compressed data stream. Each mask constructed by the method is selected from a set of valid values that can pass through the restricted channel.
