    摘要: A method of encoding video using a plurality of reference pictures is provided. The method includes: writing one of a parameter or a flag into one or more reference pictures of the plurality of reference pictures, creating a first list of reference pictures comprising the plurality of reference pictures sorted based on the parameter or flag, and encoding a current picture of the video using at least the first list of reference pictures. A method of decoding video using a plurality of reference pictures is also provided. The method includes parsing one of a parameter or flag from one or more reference pictures of the plurality of reference pictures, creating a first list of reference pictures comprising the plurality of reference pictures sorted based on the parameter or flag, and decoding a current picture of the video using at least the first list of reference pictures. In addition, there are provided corresponding apparatuses for encoding and decoding video.

    摘要: An image coding method decodes a coded stream which is generated by inter prediction coding a moving picture and includes processing units and a header of such units, the processing units including at least one processing unit divided in a hierarchy, the hierarchy including: a highest hierarchical layer in which a coding unit is a largest processing unit; and a lower hierarchical layer in which a prediction unit exists. The method comprises: identifying, by parsing hierarchy depth information stored in the header and indicating a hierarchical layer higher than a lowest hierarchical layer in which a smallest prediction unit exits, a hierarchical layer which is indicated by the hierarchy depth information or a hierarchical layer higher than the indicated hierarchical layer, the hierarchical layer having a prediction unit that stores an adaptive motion vector resolution switch flag necessary for decoding; and decoding the prediction unit, using the flag.

    摘要: A video encoding method using reference pictures includes: writing a parameter indicating a temporal level of a reference picture or a period of a type of a reference picture into the reference picture for each of the reference pictures, creating a first list of reference pictures comprising the reference pictures sorted based on the parameter; and encoding a current picture of the video using at least the first list of reference pictures. A video decoding method using a reference pictures includes: parsing a parameter indicating a temporal level of a reference picture or a period of a type of a reference picture from each of the reference pictures; creating a first list of reference pictures comprising the reference pictures sorted based on the parameter; and decoding a current picture of the video using at least the first list of reference pictures. Corresponding video encoding and decoding apparatuses are provided.
