    摘要: A method of encoding a video based on a bit depth increment, the method including: determining a scaling method so that a dynamic range, which is based on a bit depth of a restored image decreased by de-scaling that is performed to decrease the bit depth increment, is identical to a dynamic range based on a bit depth of an input image, and generating an internal image having the bit depth increment by applying the scaling method to pixel values of the input image; and determining and encoding coding units having a tree structure, for each maximum coding unit of the internal image having the bit depth increment.

    摘要: A video coding and decoding method using a weighted prediction and an apparatus for the same are provided. The video coding method includes generating a predicted image for a present block; generating a weighted prediction factor which is a scaling factor of the predicted image that minimizes the difference between the present block and the predicted image; generating a weighted prediction image by multiplying the predicted image by the weighted prediction factor; and coding a residual signal generated by subtracting the weighted prediction image from the present block.

    摘要: Provided are methods and apparatuses for encoding and decoding a motion vector. The method of encoding a motion vector includes: selecting a mode from among a first mode in which information indicating a motion vector predictor of at least one motion vector predictor is encoded and a second mode in which information indicating generation of a motion vector predictor based on pixels included in a previously encoded area adjacent to a current block is encoded; determining a motion vector predictor of the current block according to the selected mode and encoding information about the motion vector predictor of the current block; and encoding a difference vector between a motion vector of the current block and the motion vector predictor of the current block.
