A system on chip includes a video codec configured to output syntax information and data information, which correspond to each of a plurality of blocks included in each frame of image data, based upon a result of encoding or decoding the image data. A map generator is configured to determine whether each of the blocks is an update block based upon the syntax information and to generate a mapping table based upon a determination result.
