Abstract:
1. An apparatus for encoding a moving picture, comprising: a coding mode determiner configured to divide an input image into a plurality of coding units and determine a prediction mode of each coding unit; a transform/quantization unit configured to transform and quantize a transform block generated according to the prediction mode to generate a quantized block; an inverse transform/quantization unit configured to inversely quantize and inversely transform the quantized block; a deblocking filter configured to perform a deblocking filtering process to image data received from the inverse quantization/transform unit; and an entropy coder configured to entropy-code coefficients of the quantized block, wherein, when a size of the quantized block is equal to 8×8 in an intra prediction the entropy coder divides the coefficients of the quantized block into a plurality of subsets and scans non-zero coefficients of each subset according to a scan pattern determined by an intra prediction mode to entropy-code the scanned non-zero coefficients.
