Method for coding a picture sequence, corresponding method for reconstruction and stream of coded data representative of said sequence

摘要

A method for reconstruction of a picture sequence coded in accordance with a coding method specifying a set of coding tools and/or their associated coding parameters is disclosed. The pictures being divided into coding entities. The method for reconstruction according to the invention comprises the following steps for each coding entity coded in INTER mode:
determining for the coding entity at least one reference picture, andreconstructing the coding entity from the at least one reference picture with coding tools configured by coding parameters associated with the coding tools.

Advantageously, the coding tools and/or the associated coding parameters depend on the reference picture.

1. A method for reconstruction of a picture sequence coded in accordance with a method for coding specifying a set of coding tools and/or their associated coding parameters, said pictures being divided into coding entities comprising:
determining for a coding entity coded in INTER mode at least one reference picture, said coding entity belonging to a part of the picture, decoding, from a header associated with said part of the picture one single profile identifier for each reference picture used to reconstruct coding entities of said part of the picture; reconstructing said coding entity from the at least one reference picture with coding tools configured by coding parameters associated with said coding tools, wherein said coding tools and/or their associated coding parameters are defined by the profile identified by said single profile identifier.
