摘要: A video encoding/decoding apparatus including a encoder for generating prediction block, residual block by subtracting the from current block. The is frequency-transformed transforming and quantizing masked masking using one or more frequency mask tables. encoding information about table used includes decoder extracting quantized coefficient string recorded in bitstream. zero setting all coefficients at positions of no records bitstream string. inversely scanning generated
