Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

Commission) form the specialized system for worldwide standardization. National bodies that are

members of ISO or IEC participate in the development of International Standards through technical

committees established by the respective organization to deal with particular fields of technical

activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international

organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the

work.

The procedures used to develop this document and those intended for its further maintenance

are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria

needed for the different types of document should be noted. This document was drafted in

accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or

www.iec.ch/members_experts/refdocs).

Attention is drawn to the possibility that some of the elements of this document may be the subject

of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent

rights. Details of any patent rights identified during the development of the document will be in the

Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents) or the IEC

list of patent declarations received (see https://patents.iec.ch).

Information technology — Coded representation of
immersive media —
Part 10:
Carriage of visual volumetric video-based coding data
AMENDMENT 1: Support of packed video data
Normative references
Add the following reference:

ISO/IEC 14496-1, Information technology — Coding of audio-visual objects — Part 1: Systems

Update the reference ISO/IEC 23090-5:2021 to ISO/IEC DIS 23090-5:2021 .
Clause 3

Add a reference to ISO/IEC 14496-1 and ISO/IEC 14496-12 to the introductory sentence as follows:

For the purposes of this document, the terms and definitions given in ISO/IEC 14496-1, ISO/IEC 14496-12,

ISO/IEC 23090-5 and the following apply.
3.2
Replace the definition of 3.2 and note 1 to entry as follows:
V3C content
volumetric media that is encoded using V3C or its derived specification

Note 1 to entry V3C is defined in ISO/IEC 23090-5 and an example of derived specification is ISO/IEC 23090-12.

5.3.5, Table 5

Replace the V3C configuration item property four character code value ‘v3cp’ with ‘v3cC’.

5.3.6, Table 6
Add the following new row at the bottom of Table 6:
v3vp
7.4.6.3 Referenced track is a V3C video component track carrying packed
data

1) Under preparation. Stage at the time of publication: ISO/IEC DIS 23090-5:2021.

ISO/IEC 23090-10:2022/Amd. 1:2022(E)
Clause 6
Replace the entire clause with the following text:

Volumetric media related descriptions and definitions in ISO/IEC 14496-12:2022 apply.

7.2.1.1
Replace the first dashed item in the list with the following:

— num_of_v3c_parameter_sets in V3CDecoderConfigurationRecord shall be equal to 1.

Add a new dashed item in the list:

— NAL units of the same type and with the same array_completeness value should always be stored

in a single setup unit array.
7.2.1.3

After the semantic definition of v3c_parameter_set_length add the following note:

NOTE v3c_parameter_set_length syntax element defined in ISO/IEC 23090-5 can be represented by

up to 64 bits, this document limits the representation of the information to 16 bits as it suffice in practical

implementations.
7.2.1.2

Replace the syntax for V3C decoder configuration record to include version explicitly as follows:

aligned(8) class V3CDecoderConfigurationRecord(unsigned int version) {
if(version == 0){
unsigned int(3) unit_size_precision_bytes_minus1;
unsigned int(5) num_of_v3c_parameter_sets;
for (int i=0; i < num_of_v3c_parameter_sets; i++) {
unsigned int(16) v3c_parameter_set_length;
// v3c_unit() as defined in ISO/IEC FDIS 23090-5
v3c_unit v3c_parameter_set(v3c_parameter_set_length);
}
unsigned int(8) num_of_setup_unit_arrays;
for (int j=0; j < num_of_setup_unit_arrays; j++) {
unsigned int(1) array_completeness;
bit(1) reserved = 0;
unsigned int(6) nal_unit_type;
unsigned int(8) num_nal_units;
for (int i=0; i < num_nal_units; i++) {
unsigned int(16) setup_unit_length;
// nal_unit(size) as defined in ISO/IEC FDIS 23090-5
nal_unit setup_unit(setup_unit_length);
}
}
}
7.2.1.3
Update the semantics related to setup_unit as follows:

setup_unit contains a NAL unit according to related nal_unit_type. When present in setup_unit,

NAL_PREFIX_ESEI, NAL_PREFIX_NSEI, NAL_SUFFIX_ESEI, or NAL_SUFFIX_NSEI contain SEI messages

of a ‘declarative’ nature, that is, those that provide information about the stream as a whole.

ISO/IEC 23090-10:2022/Amd. 1:2022(E)
7.2.2.2

Replace the syntax for V3C configuration box to pass version information to V3C decoder configuration

record as follows:
class V3CConfigurationBox extends FullBox('v3cC', version = 0, 0) {
V3CDecoderConfigurationRecord decoder_config(version);
7.2.2.3
Replace entire contents of the subclause with the following:

decoder_config contains a single instance of V3CDecoderConfigurationRecord which is defined in

subclause 7.2.1
7.3.2.1
Replace the second and third paragraphs with the following text:

A V3C bitstream track sample entry shall contain a V3CConfigurationBox, as defined in subclause 7.2.2,

with the following restrictions:

— under the 'v3e1' sample entry, the value of array_completeness shall be 1 for arrays containing atlas

parameter sets,

— under the 'v3eg' sample entry, the value of array_completeness should be 0 for arrays containing

atlas parameter sets.
7.4.1
Replace the last paragraph and dashed items with the following:
A multi-track encapsulated V3C data container shall include the following:
— One or more V3C atlas track(s) which may include track references:

— to other tracks carrying the payloads of video compressed V3C units (i.e., V3C unit types equal

to V3C_OVD, V3C_GVD, V3C_AVD, or V3C_PVD as specified in ISO/IEC 23090-5)
— to V3C atlas tile tracks
— to other V3C atlas tracks when multiple atlases are present in the bitstream

— Zero or more V3C video component tracks where the samples contain access units of a video-coded

elementary stream for occupancy data (i.e., payloads of V3C units of type equal to V3C_OVD as

specified in ISO/IEC 23090-5).

— Zero or more V3C video component tracks where the samples contain access units of video-coded

elementary streams for geometry data (i.e., payloads of V3C units of type equal to V3C_GVD as

specified in ISO/IEC 23090-5).

— Zero or more V3C video component tracks where the samples contain access units of video-coded

elementary streams for attribute data (i.e., payloads of V3C units of type equal to V3C_AVD as

specified in ISO/IEC 23090-5).

ISO/IEC 23090-10:2022/Amd. 1:2022(E)

— Zero or more V3C video component tracks where the samples contain access units of video-coded

elementary streams for packed data (i.e., payloads of V3C units of type equal to V3C_PVD as specified

in ISO/IEC 23090-5).
7.4.2.1
Replace the text associated with dashed items with following:

V3C atlas tracks use V3CAtlasSampleEntry which extends VolumetricVisualSampleEntry with a

sample entry type of 'v3c1', 'v3cg', 'v3cb', 'v3a1', or 'v3ag'. Following restrictions are set for

V3C atlas tracks:

— A V3C atlas track shall not carry ACL NAL units belonging to more than one atlas.

— A V3C atlas track sample entry contains a V3CConfigurationBox, as defined in subclause 7.2.2, and a

V3CUnitHeaderBox, as defined in subclause 7.2.3.

NOTE V3C atlas tracks with sample entry type 'v3cb', 'v3a1' and 'v3ag' are relevant for carrying

multiple atlases.

Depending on V3C bitstream content or sample entry type of the atlas track, following restrictions are

placed on V3C atlas tracks:

— When the V3C bitstream contains a single atlas, a V3C atlas track with sample entry 'v3c1' or 'v3cg'

shall be used.

— When the V3C bitstream contains multiple atlases, each atlas bitstream shall be stored as a separate

V3C atlas track with the sample entry type 'v3a1' or 'v3ag'. One additional track with the sample

entry type 'v3cb' shall be present, which is the entry point track referencing the other atlas tracks

with 'v3a1' or 'v3ag'.
— Under the 'v3a1' and 'v3ag' sample entry, t
