Claim 7:
8. A device for encoding a video sequence, the device comprising:
at least one memory configured to store program code; and
at least one processor configured to read the program code and operate as instructed by the program code to implement:
determining a value of a temporal sublayer identifier max_tid_il_ref_pics_plus1[i] of a video coding layer (VCL) network abstraction layer (NAL) unit in a video sequence, wherein max_tid_il_ref_pics_plus1[i] is constrained to be less than or equal to a value of vps_max_sublayers_minus1 that specifies a maximum number of temporal sublayers capable of being present in a layer in each coded video sequence referring to a video parameter set (VPS), in the VPS referred to by the VCL NAL unit;
setting the value of max_tid_il_ref_pics_plus1[i] in the video sequence, wherein the value of max_tid_il_ref_pics_plus1[i] being zero specifying that inter-layer prediction is not used by non-intra random access point (IRAP) pictures of an i-th layer; and
encoding the video sequence comprising the value of max_tid_il_ref_pics_plus1[i].
