scope of this Specification. NOTE 2 - The sample aspect ratio (SAR) indicated in the VUI parameters should indicate the output picture shape for the packed decoded frame output by a decoder that does not interpret the frame packing arrangement SEI message. In the examples shown in Figure D-1 to Figure D-10, the SAR produced in each upconverted colour plane would be the same as the SAR indicated in the VUI parameters, since the illustrated upconversion process produces the same total number of samples from each constituent frame as existed in the packed decoded frame. NOTE 3 - When the output time of the samples of constituent frame 0 differs from the output time of the samples of constituent frame 1 (i.e., when field_views_flag is equal to 1 or frame packing arrangement type is equal to 5) and the display system in use presents two views simultaneously, the display time for constituent frame 0 should be delayed to coincide with the display time for constituent frame 1. (The display process is not specified in this Recommendation | International Standard.) NOTE 4 - When field_views_flag is equal to 1 or frame_packing_arrangement_type is equal to 5, the value 0 for fixed_frame_rate_flag is not expected to be prevalent in industry use of this SEI message. NOTE 5 - frame_packing_arrangement_type equal to 5 describes a temporal interleaving process of different views. All other values of frame_packing_arrangement_type are reserved for future use by ITU-T ISO/IEC. It is a requirement of bitstream conformance that the bitstreams shall not contain such other values of frame_packing_arrangement_type quincunx_sampling_flag equal to 1 indicates that each colour component plane of each constituent frame is quincunx sampled as illustrated in Figure D-1 or Figure D-10, and quincunx_sampling_flag equal to 0 indicates that the colour component planes of each constituent frame are not quincunx sampled. When frame_packing_arrangement, type is equal to 0, it is a requirement of bitstream conformance that quincunx sampling_flag shal
