Claim 0:
1. 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;
when at most N samples of only one side of the first boundary are allowed to be used for a deblocking filter, and N is less than the required samples for the deblocking filter,
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.
