摘要： A method of generating a multi-channel audio signal includes: representing locations of a plurality of speakers as a plurality of polygons whose vertices are located at locations of corresponding speakers; acquiring a location of an object sound; calculating distances between the plurality of polygons and the location of the object sound; selecting one of the plurality of polygons on the basis of the calculated distances; and generating a multi-channel audio signal that corresponds to speakers corresponding to the selected polygon by mapping the object sound to the speakers corresponding to the selected polygon.

摘要： A method of performing quadrature mirror filter (QMF) synthesis filtering includes recording new samples corresponding to a current time slot at positions of samples to be discarded in a first array that includes modulated QMF sub-band samples. The method further includes extracting samples from the first array to remove aliasing between adjacent sub-bands, determining filter coefficients corresponding to the extracted samples by using modulo operation, and synthesizing a time domain sample where aliasing is removed by using the extracted samples and the filter coefficients.

摘要： Provided are an apparatus and method for spatial prediction of image data, an apparatus and method for encoding image data using the same, an apparatus and method for spatial prediction compensation of image data, and an apparatus and method for decoding image data using the same. The apparatus includes a spatial prediction unit spatially predicts pixel values of a current block of an image using neighboring blocks in a row immediately above the current block among neighboring blocks that are spatially adjacent to the current block. The spatial prediction unit performs spatial prediction after replacing pixel values of neighboring blocks in a row immediately above the current block every predetermined row unit with a predetermined reference value.
