DEFINITION

Classification: 714/FOR.157

Forward correction by block code:

Foreign art collections including subject matter in which a grouping of symbols (i.e.., a block of data or a data word) is transformed into a code word having an increased number of symbols in order to provide an increased minimum distance between code words relative to the minimum distance of the corresponding data words in order to provide for forward correction of the encoded data in the event that an error or erasure is subsequently imposed on the encoded data.
