Abstract:
1. A method of decoding context based adaptive arithmetic entropy coded data comprising the steps of; a) decoding first encoded data to produce first decoded data, b) entropy encoding the first decoded data using a parallel encoding scheme that includes context-based adaptive arithmetic encoding for at least portions of symbols contained in the first decoded data to produce second encoded data, an N-bit symbol being encoded and divided into multiple streams, at least two of the streams being encoded in parallel using a corresponding number of arithmetic encoding units, c) storing the second encoded data in a first in first out, FIFO, memory, d) reading the second encoded data from the FIFO memory, and e) decoding the second encoded data read from the FIFO memory to produce second decoded data, the second decoded data being the decoded entropy coded data.
