This document specifies a video coding technology known as versatile video coding (VVC), comprising a video coding technology with a compression capability that is substantially beyond that of the prior generations of such standards and with sufficient versatility for effective use in a broad range of applications. Only the syntax format, semantics, and associated decoding process requirements are specified, while other matters such as pre-processing, the encoding process, system signalling and multiplexing, data loss recovery, post-processing, and video display are considered to be outside the scope of this document. Additionally, the internal processing steps performed within a decoder are also considered to be outside the scope of this document; only the externally observable output behaviour is required to conform to the specifications of this document. This document is designed to be generic in the sense that it serves a wide range of applications, bit rates, resolutions, qualities and services. Applications include, but are not limited to, video coding for digital storage media, television broadcasting and real-time communication. In the course of creating This document, various requirements from typical applications have been considered, necessary algorithmic elements have been developed, and these have been integrated into a single syntax. Hence, this document is designed to facilitate video data interchange among different applications.

This document specifies the CMAF multimedia format, which contains segmented media objects optimized for streaming delivery and decoding on end user devices in adaptive multimedia presentations. CMAF specifies a track format derived from the ISO base media file format, then derives addressable media objects from CMAF tracks that can be used for storage and delivery. CMAF specifies sets of tracks that share encoding and packaging constraints that enable the selection of multiple tracks to form a multimedia presentation and allow seamless switching of alternative encodings of the same content at different bit rates, frame rates, resolution, etc. CMAF specifies a hypothetical application model that determines how tracks in a CMAF presentation are intended to be combined and synchronized to form a multimedia presentation. The model abstracts delivery to allow any delivery method. The hypothetical application model assumes a manifest and player, but CMAF does not specify a manifest, player, or delivery protocol, with the intent that any that support the hypothetical application model can be used. CMAF specifies media profiles and brands that constrain media encoding and packaging of CMAF tracks to enable seamless adaptive switching of tracks and allow devices to identify compatible content by its brand. CMAF specifies presentation profiles that conditionally require sets of CMAF tracks conforming to specified media profiles and allow content creators and devices to identify compatible multimedia presentations. CMAF enables extensibility by specifying how new media profiles and presentation profiles can be specified and identified and includes guidelines for those specifications.

The present document specifies PAdES digital signatures. PAdES signatures build on PDF signatures specified in
ISO 32000-1 [1] with an alternative signature encoding to support digital signature formats equivalent to the signature
format CAdES as specified in ETSI EN 319 122-1 [2], by incorporation of signed and unsigned attributes, which fulfil
certain common requirements (such as the long term validity of digital signatures) in a number of use cases.
The present document specifies formats for PAdES baseline signatures, which provide the basic features necessary for a
wide range of business and governmental use cases for electronic procedures and communications to be applicable to a
wide range of communities when there is a clear need for interoperability of digital signatures used in electronic
documents.
The present document defines four levels of PAdES baseline signatures addressing incremental requirements to
maintain the validity of the signatures over the long term, in a way that a certain level always addresses all the
requirements addressed at levels that are below it. Each level requires the presence of certain PAdES attributes, suitably
profiled for reducing the optionality as much as possible.
Procedures for creation, augmentation, and validation of PAdES digital signatures are out of scope and specified in
ETSI EN 319 102-1 [i.5]. Guidance on creation, augmentation and validation of PAdES digital signatures including the
usage of the different attributes defined in the present document is provided in ETSI TR 119 100 [i.4]. The present
document aims at supporting electronic signatures in different regulatory frameworks.
NOTE: Specifically but not exclusively, PAdES digital signatures specified in the present document aim at
supporting electronic signatures, advanced electronic signatures, qualified electronic signatures,
electronic seals, advanced electronic seals, and qualified electronic seals as per Regulation (EU)
No 910/2014 [i.2].

This document specifies Neural Network Coding (NNC) as a compressed representation of the parameters/weights of a trained neural network and a decoding process for the compressed representation, complementing the description of the network topology in existing (exchange) formats for neural networks. It establishes a toolbox of compression methods, specifying (where applicable) the resulting elements of the compressed bitstream. Most of these tools can be applied to the compression of entire neural networks, and some of them can also be applied to the compression of differential updates of neural networks with respect to a base network. Such differential updates are for example useful when models are redistributed after fine-tuning or transfer learning, or when providing versions of a neural network with different compression ratios. This document does not specify a complete protocol for the transmission of neural networks, but focuses on compression of network parameters. Only the syntax format, semantics, associated decoding process requirements, parameter sparsification, parameter transformation methods, parameter quantization, entropy coding method and integration/signalling within existing exchange formats are specified, while other matters such as pre-processing, system signalling and multiplexing, data loss recovery and post-processing are considered to be outside the scope of this document. Additionally, the internal processing steps performed within a decoder are also considered to be outside the scope of this document; only the externally observable output behaviour is required to conform to the specifications of this document.

This document specifies the system layer of the coding. It was developed principally to support the combination of the video and audio coding methods defined in Parts 2 and 3 of ISO/IEC 13818. The system layer supports six basic functions: 1) the synchronization of multiple compressed streams on decoding; 2) the interleaving of multiple compressed streams into a single stream; 3) the initialization of buffering for decoding start up; 4) continuous buffer management; 5) time identification; 6) multiplexing and signalling of various components in a system stream. A Rec. ITU-T H.222.0 | ISO/IEC 13818-1 multiplexed bit stream is either a transport stream or a program stream. Both streams are constructed from PES packets and packets containing other necessary information. Both stream types support multiplexing of video and audio compressed streams from one program with a common time base. The transport stream additionally supports the multiplexing of video and audio compressed streams from multiple programs with independent time bases. For almost error-free environments the program stream is generally more appropriate, supporting software processing of program information. The transport stream is more suitable for use in environments where errors are likely. A Rec. ITU-T H.222.0 | ISO/IEC 13818-1 multiplexed bit stream, whether a transport stream or a program stream, is constructed in two layers: the outermost layer is the system layer, and the innermost is the compression layer. The system layer provides the functions necessary for using one or more compressed data streams in a system. The video and audio parts of this Specification define the compression coding layer for audio and video data. Coding of other types of data is not defined by this Specification, but is supported by the system layer provided that the other types of data adhere to the constraints defined in 2.7.

The present document specifies generally applicable policy and security requirements for Trust Service Providers
(TSPs) issuing public key certificates, including trusted web site certificates.
The policy and security requirements are defined in terms of requirements for the issuance, maintenance and life-cycle
management of certificates. These policy and security requirements support several reference certificate policies,
defined in clauses 4 and 5.
A framework for the definition of policy requirements for TSPs issuing certificates in a specific context where
particular requirements apply is defined in clause 7.
The present document covers requirements for CA hierarchies, however this is limited to supporting the policies as
specified in the present document. It does not include requirements for root CAs and intermediate CAs for other
purposes.
The present document is applicable to:
• the general requirements of certification in support of cryptographic mechanisms, including digital signatures
for electronic signatures and seals;
• the general requirements of certification authorities issuing TLS/SSL certificates;
• the general requirements of the use of cryptography for authentication and encryption.
The present document does not specify how the requirements identified can be assessed by an independent party,
including requirements for information to be made available to such independent assessors, or requirements on such
assessors.
NOTE: See ETSI EN 319 403 [i.2] for guidance on assessment of TSP's processes and services. The present
document references ETSI EN 319 401 [9] for general policy requirements common to all classes of
TSP's services.
The present document includes provisions consistent with the requirements from the CA/Browser Forum in EVCG [4]
and BRG [6].

The present document specifies requirements on the content of certificates issued to natural persons. This profile builds
on IETF RFC 5280 [1] for generic profiling of Recommendation ITU-T X.509 | ISO/IEC 9594-8 [i.3].
This profile supports the requirements of EU Qualified Certificates as specified in the Regulation (EU)
No 910/2014 [i.5] as well as other forms of certificate. The scope of the present document is primary limited to
facilitate interoperable processing and display of certificate information. This profile therefore excludes support for
some certificate information content options, which can be perfectly valid in a local context but which are not regarded
as relevant or suitable for use in widely deployed applications.
The present document focuses on requirements on certificate content. Requirements on decoding and processing rules
are limited to aspects required to process certificate content defined in the present document. Further processing
requirements are only specified for cases where it adds information that is necessary for the sake of interoperability.
Certain applications or protocols impose specific requirements on certificate content. The present document is based on
the assumption that these requirements are adequately defined by the respective application or protocol. It is therefore
outside the scope of the present document to specify such application or protocol specific certificate content.
