A method of video decoding performed in a video decoder is provided. A bit stream including syntax elements is received. The syntax elements correspond to coefficients of a region of a transform skipped block in a coded picture. The syntax elements include a first flag indicating whether an absolute coefficient level of one of the coefficients is greater than 0, and a second flag indicating a parity of the absolute coefficient level of the one of the coefficients. The second flag is decoded based on an equal probability model.
