Description

There is

cross_layer_bla_flag equal to 1 affects the derivation of NoClrasOutputFlag and LayerResetFlag as specified in clause F.8.1.3. cross_layer_bla_flag shall be equal to 0 for pictures with nal_unit_type not equal to IDR_W_RADL or IDR_N_LP or with nuh_layer_id nuhLayerId not equal to any value for which NumDirectRefLayers[ nuhLayerId ] is equal to 0. When not present, the value of cross_layer_bla_flag is inferred to be equal to 0.

in text. It is not clear what nuh_layer_id nuhLayerId means.

Here, we were defining a variable representing nuh_layer_id. 'nuh_layer_id nuhLayerId' means 'A variable nuhLayerId with the value equal to nuh_layer_id of the picture'.

I think reader could spent little less efforts to parse the phrase, if it was like

cross_layer_bla_flag shall be equal to 0 for pictures with nal_unit_type not equal to IDR_W_RADL or IDR_N_LP or with nuh_layer_id for which NumDirectRefLayers[ nuh_layer_id ] > 0.

  • Resolution set to fixed
  • Status changed from new to closed

I think the original text should be clear enough.
