Abstract
Various embodiments of the present technology may comprise methods and apparatus for transform coefficient encoding and decoding. Methods and apparatus for transform coefficient encoding and decoding may comprise an entropy encoder configured to encode each transform coefficient as a symbol, wherein the symbol comprises a context, a magnitude, and a mantissa. The context may be one of four contexts and the symbol may be encoded using a subset of Huffman codes, wherein the subset is determined based on the context.
