lue[c][i]| indicates the colour correlation between consecutive colour components. Otherwise (model id is equal to 1), comp_model_value[c][i] indicates the second order spatial correlation for neighbouring samples (x, y and (x y). film_grain_characteristics_repetition_period specifies the persistence of the film grain characteristics SEI message and may specify a picture order count interval within which another film grain characteristics SEI message or the end of the coded video sequence shall be present in the bitstream. The value of ilm_grain_characteristics_repetition_period shall be in the range 0 to 384, inclusive. film_grain_characteristics_repetition_periodequal to 0 specifies that the film grain characteristics SEI message applies to the current decoded picture only. Rec. ITU-T H.264 (01/2012) film_grain_characteristics_repetition_periodequal to 1 specifies that the film grain characteristics SEI message persists in output order until any of the following conditions are true: A new coded video sequence begins. A picture in an access unit containing a film grain characteristics SEI message is output having PicOrderCnt() greater than PicOrderCnt( CurrPic). film_grain_characteristics_repetition_period greater than 1 specifies that the film grain characteristics SEI message persists until any of the following conditions are true: A new coded video sequence begins. A picture in an access unit containing a film grain characteristics SEI message is output having PicOrderCnt() greater than PicOrderCnt( CurrPic) and less than or equal to PicOrderCnt( CurrPic ) film_grain_characteristics_repetition_period film_grain_characteristics_repetition_periodgreater than 1 indicates that another film grain characteristics SEI message shall be present for a picture in an access unit that is output having PicOrderCnt() greater than PicOrderCnt( CurrPic ) and less than or equal to PicOrderCnt( CurrPic + film_grain_characteristics_repetition_period; unless the bitstream ends or a new coded video sequence begins without output o
