A technique for use in, illustratively, a transform coder for imparting robustness against burst (or similar) errors to data patterns, such as illustratively two-dimensional image data, that exhibit local redundancy. Robustness is provided, in the case of images, by passing localized (blocked) image...http://www.google.ca/patents/US5293434?utm_source=gb-gplus-sharePatent US5293434 - Technique for use in a transform coder for imparting robustness to compressed image data through use of global block transformations
