Abstract: Method and apparatus of coding a video sequence are disclosed. According to this method, a first syntax is signalled in or parsed from a bitstream, where the first syntax indicates whether a loop filtering process is disabled for one or more virtual boundaries in a corresponding region. A reconstructed filter unit in a current picture is received, wherein the reconstructed filter unit is associated with the loop filter and the reconstructed filter unit comprises reconstructed pixels for applying a loop filtering process associated with the loop filter to a current reconstructed pixel. When the first syntax is true, the loop filter processing is disabled when the reconstructed filter unit is across said one or more virtual boundaries in the corresponding region. When the first syntax is false, the loop filter processing is not disabled when the reconstructed filter unit is across the virtual boundary.
