摘要： Methods and apparatuses for efficiently coding and decoding multi-view video are provided. A method of decoding multi-view video includes: interpreting a first picture type indicating whether a current picture of the multi-view video is a reference video type for inter prediction; interpreting a block type indicating a method of determining a motion vector of a current block of the current picture; interpreting a chrominance compensation value of the current block based on at least one of the interpreted first picture type and the interpreted block type; and performing chrominance compensation on the current block by using the interpreted chrominance compensation value.

摘要： Methods and apparatuses for efficiently coding and decoding multi-view video are provided. A method of decoding multi-view video includes: interpreting from a received bitstream a block type indicating a method of determining a motion vector of a current block present in a current picture of the multi-view video; interpreting a first picture type indicating whether the current picture is a reference picture type for inter prediction; interpreting additional information of the current picture based on at least one of the interpreted first picture type and the interpreted block type; and reconstructing the current block and the current picture by using the additional information.

摘要： A method for coding image information includes generating prediction information by predicting information on a current coding unit, and determining whether the information on the current coding unit is the same as the prediction information. When the information on the current coding unit is the same as the prediction information, a flag indicating that the information on the current coding unit is the same as the prediction information is coded and transmitted. When the information on the current coding unit is not the same as the prediction information, a flag indicating that the information on the current coding unit is not the same as the prediction information and the information on the current coding unit are coded and transmitted. At the generating of the prediction information, the prediction information is generated by using the information on the coding unit neighboring to the current coding unit.

摘要： Disclosed are a method and an apparatus for coding/decoding an image. The method for decoding the image comprises the steps of: deriving a scale factor of a current block, depending on whether the current block is a conversion skip block; and scaling the current block on the basis of the scale factor, wherein the scale factor of the current block is derived on the basis of the position of a conversion coefficient inside the current block, and wherein the conversion skip block is the current block to which conversion is not applied and is specified on the basis of information indicating whether to apply reconversion to the current block.
