f model id is equal to 0, comp_model_value[ C ][ i ][ 2 ] indicates the vertical high cut frequency to be used to filter the DCT of a block of 16x16 random values. Otherwise (model_id is equal to 1), comp_model_value[c][i]: indicates the colour correlation between consecutive colour components. comp_model_value[ c ][ 3 ] provides the fourth model value for the model as specified by model_id. When model id is equal to 0, comp_model_value C shall be greater than or equal to 0 and less than or equal to comp_model_value[c][i][1] When not present in the film grain characteristics SEI message, comp_model_value[ shall be inferred to be equal to 0. comp_model_value[ c ][ i 3 ] is interpreted as follows: If model id is equal to 0, comp_model_value[ C ][ i ][ 3] indicates the horizontal low cut frequency to be used to filter the DCT of a block of 16x16 random values. Otherwise (model id is equal to 1), comp_model_value[ 3 ] indicates the first order spatial correlation for neighbouring samples (x-1,y-1) and (x+1, y 1). comp_model_value[ i ][ 4 provides the fifth model value for the model as specified by model id When model id is equal to 0, comp_model_value[c][i][4] shall be greater than or equal to 0 and less than or equal to comp_model_value[c]i] 2]. When not present in the film grain characteristics SEI message, comp_model_value[ c][i][4] shall be inferred to be equal to model id. comp_model_value[c][ i ][ 4 ] is interpreted as follows: If model id is equal to 0, comp_model_value[ C ][ i ][ 4 ] indicates the vertical low cut frequency to be used to filter the DCT of a block of 16x16 random values. Otherwise (model_id is equal to 1), comp_model_value[ C ][ i ][ 4 indicates the aspect ratio of the modelled grain. comp_model_value[ C ][ i ][ 5 ] provides the sixth model value for the model as specified by model id. When not present in the film grain characteristics SEI message, comp_model_value[ shall be inferred to be equal to 0. comp_model_value[c ][ 5 ] is interpreted as follows: If model id is equal to 0, comp_model_va
