Abstract
A method and apparatus for deblocking reconstructed video in a video coding system. The method receives reconstructed pixel data, wherein the reconstructed pixel data is configured into LCUs (largest coding units) and each LCU is divided into blocks. The method then identifies horizontal block edges of the blocks in the LCUs, applies first vertical filtering to the reconstructed pixel data corresponding to one or more first lines above a first horizontal block edge in the first edge group, and applies second vertical filtering to the reconstructed pixel data corresponding to one or more second lines above a second horizontal block edge in the second edge group, wherein a first number of said one or more first lines is smaller than a second number of said one or more second lines.
