A method, for use in a video signal encoding system, for processing a block of quantized transform coefficients first divides the block of quantized transform coefficients into a predetermined number of subblocks and detects one or more non-zero subblocks, each of the non-zero subblocks having at least one non-zero valued quantized transform coefficients therein. Thereafter, a predetermined sequence of the quantized coefficients is provided based on the detected non-zero valued subblocks, the provided sequence of the quantized transform coefficients consisting of all the coefficients within the non-zero subblocks. The predetermined sequence of the coefficients is then runlength and variable length coded for the transmission thereof.
