In the same or another embodiment, the nuh_layer_id value of a SPS NAL unit may be equal to the lowest nuh_layer_id value of the PPS NAL units that refer to the SPS NAL unit.
In an embodiment, when an SPS with nuh_layer_id equal to m is referred to by one or more PPS with nuh_layer_id equal to n. the layer with nuh_layer_id equal to m may be the same as the layer with nuh_layer_id equal to n or a (direct or indirect) reference layer of the layer with nuh_layer_id equal to m.
In an embodiment, a PPS (RBSP) shall be available to the decoding process prior to it being referenced, included in at least one AU with TemporalId equal to the TemporalId of the PPS NAL unit or provided through external means.
In an embodiment, a PPS (RBSP) may be available to the decoding process prior to it being referenced, included in at least one AU with TemporalId equal to the TemporalId of the PPS NAL unit in the CVS, which contains one or more PHs (or coded slice NAL units) referring to the PPS, or provided through external means.
In an embodiment, a PPS (RBSP) may be available to the decoding process prior to it being referenced by one or more PHs (or coded slice NAL units), included in at least one PU with nuh_layer_id equal to the lowest nuh_layer_id value of the coded slice NAL units that refer to the PPS NAL unit in the CVS, which contains one or more PHs (or coded slice NAL units) referring to the PPS, or provided through external means.
