    摘要: A method and an apparatus for encoding a motion vector, and a method and an apparatus for encoding/decoding an image using the same are disclosed. The apparatus includes: a prediction candidate selector for selecting one or more motion vector prediction candidates; a predicted motion vector determiner for determining a PMV among the one or more motion vector prediction candidates; and a differential motion vector encoder for calculating a differential motion vector encoder for calculating a DMV by subtracting the predicted motion vector having been determined, from the current motion vector, and encoding the d having been calculated. The apparatus encodes a motion vector by using the prediction motion vector which is more accurately predicted, and reduces an amount of bits required for encoding information of the predicted motion vector, thereby improving the compression efficiency.

    摘要: The present disclosure relates to an apparatus and method for encoding/decoding videos using prediction direction change and selective encoding. The present disclosure provides a video encoding apparatus that encodes the current block of a video, comprising a rectangle encoder for dividing and then successively encoding the current block at input into rectangular block units to output a rectangularly encoded bitstream; a square encoder for encoding the current block at input in square block units to output a squarely encoded bitstream; and an encoding selector for calculating the encoding costs of the rectangularly encoded bitstream and the squarely encoded bitstream so as to output the bitstream with a minimum encoding cost. According to the present disclosure, the prediction accuracy may be increased when encoding or decoding videos so that video encoding efficiency can be improved.

    摘要: The present disclosure relates to a video encoding/decoding apparatus and method using a multi-dimensional integer transform. The video encoding method of the present disclosure includes: decomposing subblocks in units of a rectangular block and successively encoding rectangular block units to output a rectangularly encoded bitstream of each subblock; encoding the subblocks in units of a square block to output a squarely encoded bitstream of each subblock; calculating an encoding cost involving at least one rectangularly encoded bitstream; calculating an encoding cost not involving the rectangularly encoded bitstream; and on the basis of the calculations, using one or more of the squarely encoded bitstream and the rectangularly encoded bitstream to generate and output the bitstream of the macroblock. According to the disclosure, since the coding scheme for encoding or decoding a video with a higher efficiency is selectively determined, the prediction accuracy can increase and thereby improve the video encoding efficiency.
