PARAMETARY RECORDING PROCEDURES FOR ENTROPING AND DECODING CONVERSION COEFFICIENCY LEVELS, ENTROPICAL AND ENTROPIED CODINATION LEVELS ON CONVERSION COEFFICIENCY LEVELS USED

摘要

An apparatus (200) of decoding a video, a method of encoding a video and a computer-readable storage medium are disclosed. Embodiments obtain a bin string corresponding to a transformation coefficient level syntax element indicating a size of transformation coefficient included in a transformation unit from a bit stream. Embodiments determine whether to update a previous parameter by comparing a size of a previous transformation coefficient that is restored before a current transformation coefficient. Embodiments obtain the size of the current transformation coefficient by de-binarizing the current transformation coefficient level syntax element by using the obtained current parameter.
