<p>An encoded representation (60) of a picture (10) of a video stream (1) is decoded by retrieving buffer description information defining at least one reference picture (40, 42). The buffer description information is used to determine a picture identifier of a reference picture (40, 42), which is compared to picture identifiers of reference pictures (40, 42) stored in a decoded picture buffer (230, 350). If the reference picture (40, 42) is determined to be missing based on the comparison of picture identifiers the layer identifier of the reference picture (40, 42) obtained based on the buffer description information is compared to a layer identifier of the current picture (10) in order to determine whether the missing reference picture (40, 42) has been intentionally removed or is unintentionally lost.</p> |
