AHG9: Constraints on ALF APS
Authors: Xiang Ma Huawei Hyeong-Gyun Yang Huawei
Abstract
There are three types of adaptation parameter set (APS): ALF_APS, LMCS_APS, and SCALING_APS. For each type of APS, there is an ID in picture header (PH) to specify the APS ID of the APS that the slices associated with the PH refers to. In the current VVC draft specification, for APS NAL units with aps_params_type equal to LMCS_APS and SCALING_APS, there are constraints on the TemporalId of the APS NAL unit and the TemporalId of the picture associated with PH, while for APS NAL units with aps_params_type equal to ALF_APS, there is no such kind of constraint. It is proposed to add the TemporalId constraint between the ALF_APS NAL unit and the the picture associated with PH.
