摘要:
An image coding method according to an aspect of the present invention includes: writing, into a sequence parameter set, buffer description defining information for defining a plurality of buffer descriptions (S102); writing, into the sequence parameter set, reference list description defining information for defining a plurality of reference list descriptions corresponding to the buffer descriptions (S103); and writing, into a first header of each processing unit which is included in a coded bitstream, buffer description selecting information for specifying a selected buffer description (S105).

摘要:
An image coding method includes: writing, into a coded bitstream, buffer description defining information for defining a buffer description (S101); constructing a default reference list (S102); reordering pictures included in the default reference list (S103); writing, into the coded bitstream, reference list reordering information for indicating details of the reordering (S104); and coding an image using the buffer description and a reference list resulting from the reordering (S105), and in the reference list reordering information, among the pictures, a picture to be reordered is specified using an index which is used in other processing in the image coding method.
摘要:
A method of encoding video including: writing a plurality of predetermined buffer descriptions into a sequence parameter set of a coded video bitstream; writing a plurality of updating parameters into a slice header of the coded video bitstream for selecting and modifying one buffer description out of the plurality of buffer descriptions; and encoding a slice into the coded video bitstream using the slice header and the modified buffer description.
摘要:
A method of encoding a video into a coded video bitstream with temporal motion vector prediction comprises: determining a value of a flag for indicating whether temporal motion vector prediction is used or not used for the inter-picture prediction of a sub-picture unit of a picture; and writing the flag having the value into a header of the sub-picture unit or a header of the picture; wherein if the flag indicates that temporal motion vector prediction is used, the method further comprises: creating a first list of motion vector predictors comprising a plurality of motion vector predictors including at least one temporal motion vector predictor derived from at least one motion vector from a collocated reference picture; selecting a motion vector predictor out of the first list; and writing a first parameter into the coded video bitstream for indicating the selected motion vector predictor out of the first list.
