Abstract
In one embodiment of a method, system, and apparatus described herein, an encoded video is received. At least one set of areas of a spatially distinct region of a video frame to be modified is selected. An entropy layer from the spatially distinct region of a video frame. A state of the removed entropy layer and the location of a first area of the set of areas of the spatially distinct region of the video frame is stored. One area of the set of areas is decoded, the decoding occurring recursively until all areas of the set of areas of the spatially distinct region of the video frame for predicting and decoding the one area are decoded. A modification of the decoded one area is performed. The modified decoded one area is re-encoded according to a re-encoding condition. The stored state of the entropy layer is retrieved, and the entropy layer is re-applied at the first area to the spatially distinct region of the video frame which comprises the set of areas. Related methods, systems and apparatus are also described.
