Abstract: The present invention relates to an image encoding/decoding method and device, and the image encoding method or device according to an embodiment of the present invention may encode a position of a reference coefficient within a current transform block to be encoded, and encoding skip region information of a skip region selected on the basis of the position of the reference coefficient. The skip region information may represent whether or not coefficients within the skip region have an identical coefficient value.

Abstract: An apparatus for preventing a writing error from occurring on an optical disc. The apparatus includes an interpolation ATIP sync signal detector, a number determiner, and a writing speed adjuster. The interpolation ATIP sync signal detector receives a wobble signal from the wobble signal generator of an optical disc drive to detect an interpolation ATIP sync signal from the wobble signal. The number determiner determines a number of interpolation ATIP sync signals and generates a writing speed transformation control signal based on the determination result. The writing speed adjuster receives the writing speed transformation control signal from the number determiner to adjust a writing speed of the optical disc drive.
