METHODS AND EQUIPMENT FOR ENCODING AND DECODING VIDEO DATA

Abstract

The invention relates to a method and apparatus for encoding and decoding video data. A video decoder can be configured to receive, in response to receiving the first syntactic element indicating that the information in the list of reference images is included in the image header syntactic structure; the second syntactic element in the image header syntactic structure indicating that the image data at the same location used to predict the motion vector over time will be taken from the first list of reference images or the second list of reference images; receive the video data referenced in the image header syntactic structure; And in response to the tile being tile p, setting the value for the third syntactic element associated WITH the tile and the first value for the third syntactic element, WITH the first value for the third syntactic element indicates that the image at the same position used to predict the vector moving over time will be taken from the first reference image list.
