Abstract:
1. A method for processing of video data using adaptive offset (AO), wherein a picture is partitioned into coding units for applying coding process to each coding unit, the method comprising: receiving input data to said adaptive offset, wherein the input data corresponds to reconstructed or reconstructed-and-deblocked coding units of the picture, and wherein the input data corresponds to a first reconstructed or constructed-and-deblocked color component and a second reconstructed or constructed-and-deblocked color component, and the first reconstructed or constructed-and-deblocked color component and the second reconstructed or constructed-and-deblocked color component share information associated with the adaptive offset; dividing the input data into multiple filter units, wherein boundaries of the filter units corresponding to boundaries of the coding units and each filter unit contains one or more coding unit and at least one filter unit includes two or more coding units; applying adaptive offset to the filter units by adding individual offset values to individual pixels of each filter unit to generate filtered video data, wherein said applying adaptive offset to the filter units uses same first information associated with the adaptive offset for two or more coding units in one filter unit when said one filter unit contains two or more coding units; and providing the filtered video data.
