An apparatus for decoding a sequence of frames of encoded video data includes parsing circuitry configured to parse the encoded video image data for a frame to derive encoding information for each block of the frame. The apparatus also includes feedback circuitry configured to feed back, to the parsing circuitry, encoding information for a frame for use when parsing the encoded video image data of the next frame. The encoding information includes an encoding indicator for each block. When the encoding indicators were enabled when encoding the blocks of the frame, the encoding indicator fed back for a block is the encoding indicator that was used to encode that block. When the encoding indicators for the blocks of the frame were disabled when encoding the video image data for the frame, the encoding indicator fed back for a block is an encoding indicator derived from a previous frame.
