Abstract: A video encoding method includes deriving entry point information specifying an entry point of a substream for a picture. The entry point information may include a number syntax element representing a number of offset syntax elements in a slice header; an offset syntax element representing an entry point offset between in bytes two entry points; and a length syntax element representing a bits length of the offset syntax element. A value of the length syntax element plus one corresponds to the bits length of the offset syntax element and the length syntax element is signaled when the number of the offset syntax elements is larger than 0. A value of the number syntax element corresponds to the number of offset syntax elements in the slice header, and the offset syntax element is signaled when the number of the offset syntax elements is larger than 0.

Abstract: Disclosed are a method and apparatus for encoding/decoding images. The image-decoding method comprises the steps of: receiving a bit stream including information regarding an NAL unit type; and checking whether or not the NAL unit in the bit stream is a reference picture based on said information regarding an NAL unit type and decoding the NAL unit. The information regarding an NAL unit type indicates whether the NAL unit is a reference reading picture or not a reference reading picture.

Abstract: Disclosed are a method for partitioning a block and a decoding device. A method for decoding an image comprises the steps of: partitioning one prediction unit, in which an intra prediction is performed in a predetermined intra prediction mode, into a plurality of transform units; and performing the intra prediction for each of the plurality of the transform units on the basis of the predetermined intra prediction mode. Thus, the invention increases the image encoding efficiency.

Abstract: The present invention relates to a method and apparatus for processing a video signal, which can increase the accuracy of the motion vector prediction through motion vector scaling which takes a difference in the temporal distance between reference pictures into consideration. To this end, the present invention provides a video signal processing method and a video signal processing apparatus using the same, and the method comprises the steps of: scaling at least one neighboring partition motion vector for a motion vector prediction of the current partition; scaling the neighboring partition motion vector, which has been selected, when the reference picture of the neighboring partition motion vector is different from the reference picture of the current partition; acquiring a motion vector prediction value of the current partition using the scaled motion vector; and acquiring a motion vector of the current partition using the motion vector prediction value.
