Abstract
A protocol is provided by which a current block and a neighboring block are identified and the current block is processed. In some variants a deblocking filter is applied with a filtering block size set either to the standard blocksize or to the shared blocksize, depending on whether the shared size of the current and neighboring blocks is smaller than a standard blocksize.
