Abstract:
Provided are entropy decoding and encoding methods of a video. The entropy decoding method includes obtaining a transformation unit significant coefficient flag indicating whether a non-zero transformation coefficient exists in the transformation unit, from a bitstream, determining a context model for arithmetically decoding the transformation unit significant coefficient flag, based on the transformation depth of the transformation unit and arithmetically decoding the transformation unit significant coefficient flag based on the determined context model.
