1. A method for decoding a video picture partitioned into one or more coding blocks, the method comprising:
for a coding block of said video picture having a size greater than a maximum transform size N, splitting said coding block into at least a first prediction sub-block and a second prediction sub-block, thereby generating a first prediction boundary between said first and second prediction sub-blocks,
wherein said coding block comprises at least a first transform block, a second transform block, and a first transform boundary between said first and second transform blocks,
applying a first deblocking filter to the first prediction boundary; and
applying a second deblocking filter to the first transform boundary,
wherein a distance between said first prediction boundary and said first transform boundary is 8 samples, said first deblocking filter modifies, between said boundaries, 2 samples from the first prediction boundary, and said second deblocking filter modifies, between said boundaries, 5 samples from the first transform boundary.
