Abstract

A system and methodology detects blocks conducive to error in decoded digital data (fig. 9), assesses whether an error correction should be applied to the detected block based on the determined correction application criteria (See fig. 9, item 910), and if warranted according to the assessment (See fig. 9, item 915), applies block-specific error corrections to detected blocks (fig. 9, item 920). Global error corrections (fig. 9, item 930), such as edge corrections, are also enabled (See fig. 9, item 930).
