Abstract:
Methods and apparatuses for decoding and encoding video are provided. A decoding apparatus includes a parser, a parameter determiner, and a syntax element restorer for obtaining current transformation coefficient level information by performing de-binarization of bit strings using a current binarization parameter, and generating a size of a current transformation coefficient using the current transformation coefficient level information.
