I.13.2.7 Alternative depth information SEI message semantics
The alternative depth information SEI message indicates that the view components of one output view
contain samples of multiple distinct spatially packed constituent pictures. The related output view is
not suitable to be displayed directly. This SEI message can be used by the application after the decoder
2 © ISO 2016 – All rights reserved
---------------------- Page: 5 ----------------------
ISO/IEC 14496-10:2014/Amd.3:2016(E)
output to rearrange the samples to produce additional views that are appropriate for display or use by
a server for other purposes (which are outside the scope of this document).
When the alternative depth information SEI message is present, the texture and depth views referred
to by this SEI message shall conform to the specifications in Annexes I and J, ChromaArrayType shall be
equal to 1 (4:2:0), bit_depth_luma_minus8 shall be equal to 0, bit_depth_chroma_minus8 shall be equal
to 0, and the depth representation information SEI message shall be present. The depth_representation_
type is defined in the depth representation information SEI message. The depth representation is only
carried in the luma component.
The alternative depth information SEI message, when present, shall be associated with an IDR access
unit. The information signalled in this SEI message applies to all the access units in the coded video
sequence. Also, num_anchor_refs_l0[ i ], num_anchor_refs_l1[ i ], num_non_anchor_refs_l0[ i ] and
num_non_anchor_refs_l1[ i ] shall be equal to 0 in the active SPS RBSP syntax structure for the coded
video sequence and avc_3d_extension_flag shall be equal to 0 in all VCL NAL units of the coded video
sequence.
NOTE 1 These constraints disable inter-view and inter-component prediction.
In such a coded video sequence, there shall be two output views. The base view is a complete view and
the non-base view contains a packing arrangement of 1 to 4 additional views with half the width and half
the height of the base view. Such lower-resolution views are referred to as constituent pictures herein.
NOTE 2 The view_id of the non-base view is not used in any particular way for this SEI message.
All constituent pictures have a width and a height equal to ( ( pic_width_in_mbs_minus1 + 1 ) * 8 ) and
( ( pic_height_in_map_unit_minus1 + 1 ) * 8 ) in luma samples, respectively. frame_mbs_only_flag shall
be equal to 1. The variable i, with a value from 0 to num_constituent_views_gvd_minus1 + 1, inclusive,
indicates the location of the constituent pictures in the non-base texture view as specified in Table I-4. i
equal to 0 indicates the base texture view. i greater than 0 indicates the constituent texture view.
Table I-4 — Locations of the top-left luma samples of constituent pictures packed in a non-base
texture view relative to the top-left luma sample of this picture
Constituent pic- Location of the top-left luma sample in a non-base texture view

2 ( 0, ( pic_height_in_map_unit_minus1 + 1 ) * 8 )
3 ( ( pic_width_in_mbs_minus1 + 1 ) * 8, 0 )
4 ( ( pic_width_in_mbs_minus1 + 1 ) * 8, ( pic_height_in_map_unit_minus1 + 1 ) * 8 )
The decoded depth views have the same structure as the decoded texture views, i.e., they consist of a
base depth view (i equal to 0) and a non-base depth view. The non-base depth view contains up to four
constituent depth pictures (i in the range of 1 to 4) for the constituent views. The constituent depth
pictures are packed in the non-base depth view in the same arrangement as the constituent texture
pictures as specified in Table I-4.
This arrangement of texture and depth constituent views is referred to as global view and depth (GVD)
information.
depth_type shall be equal to 0. Other values are reserved for future use by ITU-T | ISO/IEC and shall
not be present in bitstreams conforming to this document. Decoders shall ignore alternative depth
information SEI messages in which such other values are present.
num_constituent_views_gvd_minus1 plus 1 identifies the number of constituent texture pictures
packed into each texture component of the non-base view. num_constituent_views_gvd_minus1 shall
be in the range of 0 to 3, inclusive.
© ISO 2016 – All rights reserved 3
---------------------- Page: 6 ----------------------
ISO/IEC 14496-10:2014/Amd.3:2016(E)
depth_present_gvd_flag equal to 1 indicates that constituent depth pictures are packed into the depth
components of the non-base view, with a packing arrangement as described above. depth_present_gvd_
flag equal to 0 specifies that the depth component of the non-base view is not present.
Each constituent picture in the depth component of the non-base view is associated with a constituent
picture in the texture component of the non-base view in the same relative location. The number of
depth views in the coded video sequence is equal to 1 + depth_present_gvd_flag. The depth component
of the base view shall always be present, independent of the value of depth_present_gvd_flag.
NOTE 3 The following SEI message parameters can be used along with the decoded depth components to
project samples from the base view into the coordinates of constituent views such that reconstructed views can
be generated by combining projected samples and samples from the constituent views.
The function binToFp( s, e, n, v ) is specified as follows:
s −( 30 + v ) e − 31 v
binToFp( s, e, n, v ) = (−1) * ( e = = 0 ? ( 2 * n ) : ( 2 * ( 1 + n ÷ 2 ) ) ) (I-1)
NOTE 4 The above specification is similar to what is found in IEC 60559:1989, Binary floating-point arithmetic
for microprocessor systems.
z_gvd_flag equal to 1 indicates the presence of the syntax elements sign_gvd_z_near_flag[ i ], exp_
gvd_z_near[ i ], man_len_gvd_z_near_minus1[ i ], man_gvd_z_near[ i ], sign_gvd_z_far_flag[ i ], exp_
gvd_z_far[ i ], man_len_gvd_z_far_minus1[ i ], and man_gvd_z_far[ i ], for i in the range of 0 to num_
constituent_views_gvd_minus1 + 1, inclusive. z_gvd_flag equal to 0 indicates that these syntax elements
are not present.
intrinsic_param_gvd_flag equal to 1 indicates the presence of intrinsic camera parameter syntax
elements. intrinsic_param_gvd_flag equal to 0 indicates that these syntax elements are not present.
rotation_gvd_flag equal to 1 indicates the presence of rotation camera parameter syntax elements.

Add a new subclause J.13.2.2 “Alternative depth information SEI message semantics” as follows.
J.13.2.2 Alternative depth information SEI message semantics
The alternative depth information SEI message indicates that the view components of one output view contain samples of
multiple distinct spatially packed constituent pictures. The related output view is not suitable to be displayed directly.
This SEI message can be used by the application after the decoder output to rearrange the samples to produce additional
views that are appropriate for display or use by a server for other purposes (which are outside the scope of this
Recommendation | International Standard).
When the alternative depth information SEI message is present, the texture and depth views referred to by this SEI
message shall conform to the specifications in Annexes I and J, ChromaArrayType shall be equal to 1 (4:2:0),
bit_depth_luma_minus8 shall be equal to 0, bit_depth_chroma_minus8 shall be equal to 0, and the depth representation

ISO/IEC 14496-10:2014/DAM 3
information SEI message shall be present. The depth_representation_type is defined in the depth representation
information SEI message. The depth representation is only carried in the luma component.
The alternative depth information SEI message, when present, shall be associated with an IDR access unit. The
information signalled in this SEI message applies to all the access units in the coded video sequence. Also,
num_anchor_refs_l0[ i ], num_anchor_refs_l1[ i ], num_non_anchor_refs_l0[ i ] and num_non_anchor_refs_l1[ i ] shall
be equal to 0 in the active SPS RBSP syntax structure for the coded video sequence and avc_3d_extension_flag shall be
equal to 0 in all VCL NAL units of the coded video sequence.
NOTE 1 – These constraints disable inter-view and inter-component prediction.
In such a coded video sequence, there shall be two output views. The base view is a complete view and the non-base
view contains a packing arrangement of 1 to 4 additional views with half the width and half the height of the base view.
Such lower-resolution views are referred to as constituent pictures herein.
NOTE 2 – The view_id of the non-base view is not used in any particular way for this SEI message.
All constituent pictures have a width and a height equal to ( ( pic_width_in_mbs_minus1 + 1 ) * 8 ) and
( ( pic_height_in_map_unit_minus1 + 1 ) * 8 ) in luma samples, respectively. frame_mbs_only_flag shall be equal to 1.
The variable i, with a value from 0 to num_constituent_views_gvd_minus1 + 1, inclusive, indicates the location of the
constituent pictures in the non-base texture view as specified in Table J-9. i equal to 0 indicates the base texture view. i
greater than 0 indicates the constituent texture view.

4 ( ( pic_width_in_mbs_minus1 + 1 ) * 8, ( pic_height_in_map_unit_minus1 + 1 ) * 8 )
The decoded depth views have the same structure as the decoded texture views, i.e., they consist of a base depth view (i
equal to 0) and a non-base depth view. The non-base depth view contains up to four constituent depth pictures (i in the
range of 1 to 4) for the constituent views. The constituent depth pictures are packed in the non-base depth view in the
same arrangement as the constituent texture pictures as specified in Table J-9.
This arrangement of texture and depth constituent views is referred to as global view and depth (GVD) information.
depth_type shall be equal to 0. Other values are reserved for future use by ITU-T | ISO/IEC and shall not be present in
bitstreams conforming to this Specification. Decoders shall ignore alternative depth information SEI messages in which
such other values are present.
num_constituent_views_gvd_minus1 plus 1 identifies the number of constituent texture pictures packed into each
texture component of the non-base view. num_constituent_views_gvd_minus1 shall be in the range of 0 to 3, inclusive.
depth_present_gvd_flag equal to 1 indicates that constituent depth pictures are packed into the depth components of the
non-base view, with a packing arrangement as described above. depth_present_gvd_flag equal to 0 specifies that the
depth component of the non-base view is not present.
Each constituent picture in the depth component of the non-base view is associated with a constituent picture in the
texture component of the non-base view in the same relative location. The number of depth views in the coded video
sequence is equal to 1 + depth_present_gvd_flag. The depth component of the base view shall always be present,
independent of the value of depth_present_gvd_flag.
NOTE 3 – The following SEI message parameters can be used along with the decoded depth components to project samples from
the base view into the coordinates of constituent views such that reconstructed views can be generated by combining projected
samples and samples from the constituent views.
The function binToFp( s, e, n, v ) is specified as follows:
s −( 30 + v ) e − 31 v
