摘要： An apparatus and method for entropy encoding and decoding of video data. The method for entropy encoding video data includes dividing the video data into at least one partial video data portion and determining an entropy encoding mode to be used for each of the partial video data portion between at least two different entropy encoding modes and performing entropy encoding on each of the partial video data portions using the determined entropy encoding mode.

摘要： A method of removing blocking artifacts from block-coded digital images and an image reproducing apparatus using the same remove blocking artifacts from a block-coded digital image. The method includes adjusting filtering offsets on a block-by-block basis using motion vector (MV) and quantization parameter (QP) values; and performing deblocking filtering to remove the blocking artifacts from a decoded digital image using the adjusted filtering offsets. Accordingly, since the filtering offsets may be adaptively adjusted on a block-by-block basis to fit image characteristics, the blocking artifacts may be efficiently removed, thus, improving image quality.

摘要： An apparatus which processes a digital image and a method therefor which can reduce an error when calculating an output value obtained by interpolating pixel values of the input digital image. The apparatus includes an interpolation processing unit which interpolates an input digital image, and a controller which measures an interpolation interval of pixel values of the digital image, calculates a coefficient by substituting the interpolation interval for a coefficient equation stored in a register, and calculates an interpolation node for the digital image by substituting the coefficient and an output pixel position value of the digital image for an interpolation node calculation equation. The controller controls the interpolation processing unit so as to interpolate the digital image to the interpolation node. As a result, it is possible to reduce an error between an interpolated output pixel position value and an output pixel position value for the pixel values of the input digital image.

摘要： A method and apparatus for controlling digital video recording where parameters related to encoding video frames that are being currently encoded are stored when a pause command is received during recording and the method and apparatus continually record, based on the stored parameters, when the pause command stops, and a camcorder including the pause function. The method includes: receiving a pause command; storing parameters related to encoding video frames that are presently being encoded in a memory, and then stop encoding video frames that are input after the parameters are stored in the memory; and encoding video frames that are input after receiving a pause release command using parameter information related to encoding when the pause release command is received. Thus, video recording efficiency can be improved by having the pause function.
