Abstract:
An encoded representation of a picture of a video stream is decoded by retrieving buffer description from the encoded representation. The buffer description information is used to determine at least one picture identifier identifying a respective reference picture as decoding reference for the picture. A decoded picture buffer is updated based on the determined picture identifier. The encoded representation of the picture itself comprises the information needed by a decoder to identify the reference pictures required to decode the encoded representation.

Claim (Index 4):
A method of decoding an encoded representation of a picture in a video stream of multiple pictures, the method comprising:\n retrieving, from the encoded representation of the picture, buffer description information defining a plurality of reference pictures; determining, based on the buffer description information, a reference picture identifier that identifies a reference picture among the plurality of reference pictures that comprises a decoding reference for the picture; and updating a decoded picture buffer based on the reference picture identifier; wherein updating the decoded picture buffer comprises marking, prior to decoding the picture, reference pictures that are present in the decoded picture buffer and that are not associated with the reference picture identifier determined based on the buffer description information as unused for reference, wherein marking of the reference pictures is performed prior to decoding the picture.
