摘要： The present disclosure concerns a method and apparatus for selecting an intra prediction mode and a video encoding/decoding method and apparatus using same. The encoding apparatus selects an intra prediction mode of current block to encode from input video by a variation of the value of pixel adjacent to the current block; encodes a residual block from intra-predicting the current block in the selected intra prediction mode of current block to generate coded coefficient bit having a bitstream generator for generating and outputting a bitstream including the coded coefficient bit and a prediction mode bit representing the selected intra prediction mode of current block by a macroblock or subblock unit with the prediction mode bit included selectively in the bitstream depending on the variation. Accordingly, selection process of a prediction mode for image compression is simplified, a faster compression is obtained and compressed data is deflated to improve compression efficiency.

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.
