    Abstract: An apparatus for decoding an image, the apparatus including an entropy decoder that performs entropy-decoding to obtain quantized transformation coefficients of at least one transformation unit in a coding unit of the image, a decoder that determines a prediction mode of at least one prediction unit in the coding unit from information indicating the prediction mode for the at least one prediction unit, when the prediction mode is determined to be an inter prediction mode, not in an intra prediction mode, determines a size of the at least one transformation unit in the coding unit regardless of a size of the at least one prediction unit in the coding unit, and performs inverse-quantization and inverse-transformation on the quantized transformation coefficients of the at least one transformation unit to obtain residuals, and a restorer that performs inter prediction for at least one prediction unit in the coding unit to generate a predictor and restores the image by using the residuals and the predictor.

    Abstract: Disclosed is a method for operating an ultrasonic diagnostic apparatus. The method includes transmitting separate first and second ultrasonic signals to an object, receiving a first echo signal which corresponds to the first ultrasonic signal and a second echo signal which corresponds to the second ultrasonic signal, separating the received first and second echo signals in order to generate first ultrasonic data which corresponds to the first echo signal and second ultrasonic data which corresponds to the second echo signal, and displaying a first ultrasonic image which is generated based on the first ultrasonic data and a second ultrasonic image which is generated based on the second ultrasonic data. The first ultrasonic image is an ultrasonic image of a first cross-sectional surface of the object, and the second ultrasonic image is an ultrasonic image of a second cross-sectional surface of the object.

    Abstract: A method of decoding an encoded video including determining at least one coding unit by using split information extracted from a bitstream, obtaining first pattern information indicating whether residual samples of a coding unit among the at least one coding unit are equal to 0, when the first pattern information indicates the residual samples are not equal to 0, extracting from the bitstream transformation index information indicating whether a transformation unit of a current level included in the coding unit from among the at least one coding unit is split, when the transformation index information indicates a split of the transformation unit of the current level, splitting the transformation unit of the current level into transformation units of a lower level, and when the transformation index information indicates a non-split of the transformation unit of the current level, obtaining second pattern information for the transformation unit of the current level, wherein the second pattern information indicates whether the transformation unit of the current level contains one or more transform coefficients not equal to 0, wherein the transformation unit of the current level is split into four transformation units of the lower level.
