erCnt( CurrPic ) and less than or equal to PicOrderCnt( CurrPic ) + deblocking_display_preference_repetition_period. deblocking_display_preference_repetition_period greater than 1 indicates that another deblocking filter display preference 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 ) deblocking_display_preference_repetition_period unless the bitstream ends or a new coded video sequence begins without output of such a picture. D.2.22 Stereo video information SEI message semantics NOTE 1 - The stereo video information SEI message is included in this Specification primarily for historical reasons. It is now suggested to use the frame packing arrangement SEI message rather than the stereo video information SEI message to signal stereo video information. This SEI message provides the decoder with an indication that the entire coded video sequence consists of pairs of pictures forming stereo-view content. Rec. ITU-T H.264 (01/2012) The stereo video information SEI message shall not be present in any access unit of a coded video sequence unless a stereo video information SEI message is present in the first access unit of the coded video sequence. field_views_flag equal to 1 indicates that all pictures in the current coded video sequence are fields and all fields of a particular parity are considered a left view and all fields of the opposite parity are considered a right view for stereo-view content. field_views_flag equal to 0 indicates that all pictures in the current coded video sequence are frames and alternating frames in output order represent a view of a stereo view. The value of field_views_flag shall be the same in all stereo video information SEI messages within a coded video sequence. When the stereo video information SEI message is present and field_views_flag is equal to 1, the left view and right view of a stereo video pair shall be coded as a complementary field pair, th
