摘要： A method for encoding/decoding a motion vector and an apparatus thereof are disclosed. The method includes defining a candidate motion vector set with respect to a current motion vector; selecting a predicted motion vector from the candidate motion vector set; determining a predictability of the predicted motion vector in a decoding apparatus; encoding the current motion vector by using a motion vector prediction mode for indicating the predicted motion vector and the predictability, if the predictability is determined positive; and encoding the current motion vector by using a motion vector prediction mode for indicating a default predicted motion vector and an unpredictability, if the predictability is determined negative. According to the disclosure, it becomes unnecessary to directly notify of the predicted motion vector of the current motion vector to the decoding apparatus, and instead a predetermined shared function is provided to inform of or search the predicted motion vector.

The apparatus encodes the video through predicting each pixel in a current block of the video by using one or more adjacent pixels, which are encoded prior to encoding the current block and have the closest proximity to the pixels respectively in a predetermined prediction direction, and wherein the current block is sized L×M with L being unequal to M. It has become possible to predict the pixels in the block starting from closest one of the pixels in the prediction direction in order to provide more accurate block predictions and then raise the compression efficiency that leaps to more efficient video encoding/decoding performance.

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.

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.
