Abstract
A digital system is provided that converts compressed data using an indexed transcoding lookup table. A stream of compressed data samples has data samples that represent one of n values corresponding to the first compression format. The transcoding table has at least n indexed entries, and each of the n indexed entries contains a data value corresponding to a second compression format. The transcoding table is accessed by using each of a portion of the received data samples as an index into the table to form a set of transcoded data samples that have a second compression format. The set of transcoded data samples form a stream of compressed data samples that have the second compression format. The transcoding table may be augmented to perform transcoding error correction by concatenating an error value with the data sample to index the table.
