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 12):
A receiver comprising:\n an input section configured to receive encoded representations of multiple pictures in a video stream; a decoder configured to decode the encoded representations of the multiple pictures; and an output section configured to output decoded pictures of the video stream, wherein the decoder comprises: a data retriever configured to retrieve buffer description information defining a plurality of reference pictures, wherein the buffer description information is retrieved from the encoded representation of a picture; a picture identifier determiner configured to determine, based on the buffer description information, a reference picture identifier that identifies a respective reference picture among the plurality of reference pictures, the respective reference picture comprising a decoding reference for the picture, wherein the picture identifier determiner is configured to i) retrieve, based on the buffer description information, a respective delta identifier, and ii) calculate the reference picture identifier based on a picture identifier identifying the picture and the respective delta identifier; and a buffer manager configured to update a decoded picture buffer based on the reference picture identifier; wherein the buffer manager is configured to mark, prior to the decoder 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.
