tained_f flag equal to 0 indicates that some inter prediction operations within the decoding process for the left-view pictures of the coded video sequence may or may not refer to reference pictures that are right-view pictures. Within a coded video sequence, the value of left_view_self_contained_flag in all stereo video information SEI messages shall be the same. right_view_self_contained_flag equal to 1 indicates that no inter prediction operations within the decoding process for the right-view pictures of the coded video sequence refer to reference pictures that are left-view pictures. right_view_self_contained_flag equal to 0 indicates that some inter prediction operations within the decoding process for the right-view pictures of the coded video sequence may or may not refer to reference pictures that are left-view pictures. Within a coded video sequence, the value of right_view_self_contained_flag in all stereo video information SEI messages shall be the same. D.2.23 Post-filter hint SEI message semantics This SEI message provides the coefficients of a post-filter or correlation information for the design of a post-filter for potential use in post-processing of the output decoded pictures to obtain improved displayed quality. filter_hint_size_y specifies the vertical size of the filter coefficient or correlation array. The value of filter hint size shall be in the range of 1 to 15, inclusive. filter_hint_size_x specifies the horizontal size of the filter coefficient or correlation array. The value of filter hint size x shall be in the range of 1 to 15, inclusive. hint identifies the type of the transmitted filter hints as specified in Table D-7. The value of filter_hint_type shall be in the range of 0 to 2, inclusive. Decoders shall ignore post-filter hint SEI messages having filter_hint_type equa to the reserved value 3. Rec. ITU-T H.264 (01/2012) Table D-7 filter_hint_type valu Value Description coefficients of a 2D FIRfilter coefficients of two 1D FIR filters cross-correlation matrix Reserved filter_hint
