An apparatus for coding video information in a bitstream, comprising: a memory configured to store video information associated with a first layer including a first picture and a second layer including a second picture, the first picture associated with a current access unit, AU,; and a processor in communication with the memory and configured to: provide only the least significant bits, LSB, of a picture order count, POC, in a bitstream and calculate the most significant bits, MSB, according to a POC derivation process; determine whether the first picture is an intra random access point, IRAP, picture with a NoRaslOutputFlag value equal to 1, indicating that a random access skipped leading, RASL, picture is not to be output, or is the first picture of the first layer with layer identifier, nuh_layer_id, greater than 0 that follows an IRAP picture that has a nuh_layer_id value equal to 0 and has a NoClrasOutputFlag value equal to 1; indicating that cross-layer random access skip pictures are not to be output characterized in that, based on a determination that the first picture is not an IRAP picture with a NoRaslOutputFlag value equal to 1 or not the first picture of the first layer with nuh_layer_id greater than 0 that follows an IRAP picture that has a nuh_layer_id value equal to 0 and has a NoClrasOutputFlag value equal to 1, restrict picture order count, POC, values of pictures in a sub decoded picture buffer, sub-DPB, storing a plurality of pictures in a single layer, such that a difference between a highest picture order count, POC, and a lowest POC of the plurality of pictures in the sub decoded picture buffer, sub-DPB, is less than a threshold value MaxPicOrderCntLsb/2., MaxPicOrderCntLsb defining the maximum of the LSB of POC values a memory configured to store video information associated with a first layer including a first picture and a second layer including a second picture, the first picture associated with a current access unit, AU,; and a processor in communication with the memory and configured to: provide only the least significant bits, LSB, of a picture order count, POC, in a bitstream and calculate the most significant bits, MSB, according to a POC derivation process; determine whether the first picture is an intra random access point, IRAP, picture with a NoRaslOutputFlag value equal to 1, indicating that a random access skipped leading, RASL, picture is not to be output, or is the first picture of the first layer with layer identifier, nuh_layer_id, greater than 0 that follows an IRAP picture that has a nuh_layer_id value equal to 0 and has a NoClrasOutputFlag value equal to 1; indicating that cross-layer random access skip pictures are not to be output characterized in that, based on a determination that the first picture is not an IRAP picture with a NoRaslOutputFlag value equal to 1 or not the first picture of the first layer with nuh_layer_id greater than 0 that follows an IRAP picture that has a nuh_layer_id value equal to 0 and has a NoClrasOutputFlag value equal to 1, restrict picture order count, POC, values of pictures in a sub decoded picture buffer, sub-DPB, storing a plurality of pictures in a single layer, such that a difference between a highest picture order count, POC, and a lowest POC of the plurality of pictures in the sub decoded picture buffer, sub-DPB, is less than a threshold value MaxPicOrderCntLsb/2., MaxPicOrderCntLsb defining the maximum of the LSB of POC values provide only the least significant bits, LSB, of a picture order count, POC, in a bitstream and calculate the most significant bits, MSB, according to a POC derivation process; determine whether the first picture is an intra random access point, IRAP, picture with a NoRaslOutputFlag value equal to 1, indicating that a random access skipped leading, RASL, picture is not to be output, or is the first picture of the first layer with layer identifier, nuh_layer_id, greater than 0 that follows an IRAP picture that has a nuh_layer_id value equal to 0 and has a NoClrasOutputFlag value equal to 1; indicating that cross-layer random access skip pictures are not to be output characterized in that, based on a determination that the first picture is not an IRAP picture with a NoRaslOutputFlag value equal to 1 or not the first picture of the first layer with nuh_layer_id greater than 0 that follows an IRAP picture that has a nuh_layer_id value equal to 0 and has a NoClrasOutputFlag value equal to 1, restrict picture order count, POC, values of pictures in a sub decoded picture buffer, sub-DPB, storing a plurality of pictures in a single layer, such that a difference between a highest picture order count, POC, and a lowest POC of the plurality of pictures in the sub decoded picture buffer, sub-DPB, is less than a threshold value MaxPicOrderCntLsb/2., MaxPicOrderCntLsb defining the maximum of the LSB of POC values
