\nA filter is applied to every decoded macroblock to reduce blocking distortion [iv]. The de-
\nblocking filter is applied after the inverse transform in the encoder before reconstructing and
\nstoring the macroblock for future predictions and in the decoder before reconstructing and
\ndisplaying the macroblock.<\/p>\nIntra-coded macroblocks are filtered, but intra prediction (section 6.3) is carried out using unfiltered reconstructed
\nmacroblocks to form the prediction.<\/p>\nCodecVisa\u8f6f\u4ef6\u4e2dPre-LP\u8868\u793aLoop filter\u52a8\u4f5c\u4e4b\u524d\u7684\u6570\u636e\uff0cIDCT Coefficient\u8868\u793aInverse DCT Coefficient\u3002<\/p>\n
