1. A method of processing a video stream, the method comprising:
obtaining a header value from a slice header of the video stream;
deriving a further value from a plurality of most significant bits of a Picture Order Count (POC) value of a key picture and a plurality of least significant bits of the POC value of the key picture, the key picture being a picture most recently occurring in the video stream that prevents use of pictures previous to the key picture from being used to predict pictures after the key picture;
summing the further value with the header value to determine a POC value of a current picture; and
decoding the current picture based on the POC value of the current picture.
