Abstract
An encoder (80) a decoder (50) and methods for coding of a video sequence. The encoder (80) calculates (301) an indication to a previous reference picture. The previous reference picture has a temporal identity of zero. The encoder (80) creates (302) a first set of indicators to the previous reference picture to all reference pictures included in a first reference picture set of the previous reference picture and to all pictures that follow the previous reference picture in decoding order and precede the current picture in decoding order. The encoder (80) sets (303) a flag for picture order count cycle when a long term reference picture has least significant bits of a picture order count for which more than one picture indicated in the first set share the same value of the least significant bits of picture order count as the long term reference picture. The decoder (50) obtains (305) least significant bits of a picture order count for a long term reference picture included in a reference picture set of the current picture. The decoder (50) obtains (306) the flag. The decoder (50) concludes (307) non compliant bitstream when the flag indicates that the picture order count cycle is not used and the least significant bits match more than one reference picture. Corresponding computer programs and computer program products are also disclosed.
