Claim 3:
4. A method of de-blocking of reconstructed picture in for video encoding or video decoding, the method comprising:
receiving input data related to a current block in a current picture at a video encoder side or a video bitstream corresponding to compressed data including the current block in the current picture at a video decoder side;
determining a first boundary associated with the current block, wherein the first boundary corresponds to one vertical boundary or one horizontal boundary of the current block;
applying de-blocking process to a reconstructed current block corresponding to the current block to result in a filtered-reconstructed current block, using a plurality of first reference samples at a same side of the first boundary;
wherein,
replacing a first set of the first reference samples by one or more padding values, wherein the padding values are generated from a second set of the first reference samples other than the first set of first reference samples;
wherein, a filtering process includes using at least the padding samples and the second set of the first reference samples; and
generating a filtered decoded picture including the filtered-reconstructed current block,
wherein for each pixel line perpendicular to the first boundary and the second boundary, said one or more first reference samples to be modified by the de-blocking process of the second boundary are replaced by a target second reference pixel used for the de-blocking process of the second boundary, and wherein the target second reference pixel is closest to said one or more first reference samples in said each pixel line perpendicular to the first boundary.
