    摘要: The reference picture selection method according to the present invention is a method for selecting a reference picture for a current bottom field, and includes: predicting a degree of a motion of the current bottom field using a specific field which precedes the current bottom field in coding order; setting reference picture candidates suitable for coding the current bottom field based on the predicted degree of motion; and selecting a reference picture of the current bottom field among the set reference picture candidates.

    摘要: To provide a method and an apparatus for adaptively improving the image quality of current images to be coded by reducing effects due to pulsing artifacts. The video coding method of the present invention is intended for coding a video on a per predetermined block basis using one or more predetermined quantization control variables, and includes: calculating a correlation degree indicating the correlation between an original block in a current original picture to be coded and a prediction block in a previous uncompressed picture; changing a first predetermined quantization control variable to a second predetermined quantization control variable so as to reduce a quantization step size in the case where the correlation degree is greater than a predetermined threshold; and determining the quantization step size based on the second quantization control variable, and coding the original block on the determined quantization step size basis using a predetermined image coding tool.

    摘要: An image coding method determines one of frame coding and field coding while suppressing an increase in the complexity. The image coding method includes coding a current picture included in the pictures; determining whether a picture next to the current picture is to be coded in frame coding or field coding, depending on motion information that is information for indicating a motion in the current picture; and coding the next picture in frame coding when it is determined in the determining that the next picture is to be coded in frame coding, and coding the next picture in field coding when it is determined in the determining that the next picture is to be coded in field coding.

    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: A coding method includes: defining an access unit; and coding each of the pictures included in the access unit, for each access unit. The defining includes: determining a unit of coding for determining whether the pictures included in the access unit are to be uniformly coded on a per-field basis or on a per-frame basis; and determining a field type for determining whether the pictures are to be uniformly coded as top fields or bottom fields when it is determined that the pictures included in the access unit are to be coded on a per-field basis. In the coding, each of the pictures is coded for each access unit in a format determined in the determining of a unit of coding and in the determining of a field type.
