    摘要: Recent video coding schemes support different size of interpolation filter length for interpolation process. However, the schemes are using fixed, one sized interpolation filter length for all different size of picture resolutions and all different size of inter predicted units, leading to undesired large memory bandwidth usage. Especially for large spatial resolution images or large prediction blocks, the required memory bandwidth is substantially increased by using fixed interpolation filter length. The current invention provides methods and apparatuses for selecting the different interpolation filter coefficients adaptively based on a pre-determined interpolation filter length selection scheme. The benefit of the current invention is in the form of saving memory bandwidth usage.

    摘要: Provided is an image coding method for determining one of frame coding and field coding while suppressing increase in the complexity. The image coding method includes: coding a current picture included in the pictures (S100); 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 (S102); 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 (S104).

    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.
