    摘要: A video encoding/decoding apparatus and method are disclosed. The video encoding/decoding apparatus includes: a video encoder for encoding a differential value between a quantization parameter value of a macroblock of a video and a quantization parameter value of a subblock in an extended macroblock based on additional information on the macroblock and the subblock; and a video decoder for reconstructing a differential value of a quantization parameter encoded by the video encoder, reconstructing a residual block based on a reconstructed differential value of the quantization parameter, and reconstructing the video based on the residual block reconstructed.
