Abstract: PURPOSE: A method for compressing a frame memory is provided to compress data stored in a frame memory, thereby reducing the size of the frame memory. CONSTITUTION: The 4×4 pixels are quantized by a quantization parameter. An encoding process is performed by DPCM(Differential Pulse Code Modulation) encoding. The compressed data is re-compressed. The DPCM uses 8 preset scan sequences. The preset scan sequences are determined by a prediction result of internal prediction mode of H.264/AVC.
