Abstract: Various schemes for realizing efficient in-loop filtering are described, manifested in low latency and reduced hardware cost for an in-loop filter comprising at least two filtering stages. An apparatus receives pixel data of a current block of a picture and one or more neighboring blocks thereof, based on which the apparatus performs a filtering operation and generates a filtered block that includes completely filtered sub-blocks and partially filtered sub-blocks. The apparatus further outputs an output block that includes the completely filtered sub-blocks as well as a respective portion of each of the partially filtered sub-blocks, wherein the respective portion is adjacent to one of the completely filtered sub-blocks.
