1. A method of decoding an encoded representation of a picture in a video stream of multiple pictures, said method comprising:
retrieving, using a decoder configured to decode said encoded representation of said picture, buffer description information defining at least one reference picture, wherein said buffer description information is retrieved from said encoded representation of said picture;
determining, based on said buffer description information, at least one reference picture identifier, said at least one reference picture identifier identifying a respective reference picture among said at least one reference picture, said respective reference picture being a decoding reference for said picture, wherein determining said at least one reference picture identifier comprises:
(i) retrieving, based on said buffer description information, a respective delta identifier; and
(ii) calculating said at least one reference picture identifier based on a picture identifier identifying said picture and said respective delta identifier; and
updating a decoded picture buffer based on said at least one reference picture identifier.
