e such that constituent frame 0 and constituent frame 1 cover corresponding spatial areas with interleaved quincunx sampling patterns as illustrated in Figure D-1 and Figure D-10. NOTE 11 - When type is equal to 2 and field_views_flag is equal to 1, it is suggested that frame0_grid_position_y should be equal to framel grid_position_y. frame_packing_arrangement_reserved_byte is reserved for future use by ITU-T | ISO/IEC. It is a requirement of bitstream conformance that the value of frame_packing_arrangement_reserved_byte shall be equal to 0. All other values of frame packing byte are reserved for future use by ITU-T | ISO/IEC. Decoders shall ignore (remove from the bitstream and discard) the value of rame_packing_arrangement_reserved_byte frame_packing_arrangement_repetition_period specifies the persistence of the frame packing arrangement SEI message and may specify a frame order count interval within which another frame packing arrangement SEI message with the same value of rame_packing_arrangement_id or the end of the coded video sequence shall be present in the bitstream. The value of rame_packing_arrangement_repetition_period shall be in the range of 0 to 16 384, inclusive. Rec. ITU-T H.264 (01/2012) rame_packing_arrangement_repetition_period equal to 0 specifies that the frame packing arrangement SEI message applies to the current decoded frame only. ame_packing_arrangement_repetition, period equal to 1 specifies that the frame packing arrangement SEI message persists in output order until any of the following conditions are true: A new coded video sequence begins. A frame in an access unit containing a frame packing arrangement SEI message with the same value of rame_packing_arrangement_ic is output having PicOrderCnt() greater than PicOrderCnt( CurrPic ). frame packing_arrangement_repetition period equal to 0 or equal to 1 indicates that another frame packing arrangement SEI message with the same value of frame_packing_arrangement_id may or may not be present. frame_packing_arrangement_repetition_period g
