This document defines the air interface for radio frequency identification (RFID) devices operating in the 860 MHz to 960 MHz industrial, scientific, and medical (ISM) band used in item management applications. It provides a common technical specification for RFID devices that can be used to develop RFID application standards. This document is intended to allow for compatibility and to encourage inter-operability of products for the growing RFID market in the international marketplace. It defines the forward and return link parameters for technical attributes including, but not limited to, operating frequency, operating channel accuracy, occupied channel bandwidth, maximum effective isotropic radiated power (EIRP), spurious emissions, modulation, duty cycle, data coding, bit rate, bit rate accuracy, bit transmission order, and, where appropriate, operating channels, frequency hop rate, hop sequence, spreading sequence, and chip rate. It further defines the communications protocol used in the air interface. This document specifies the physical and logical requirements for a passive-backscatter, Interrogator-Talks-First (ITF) systems. The system comprises Interrogators, also known as readers, and tags, also known as labels. An Interrogator receives information from a tag by transmitting a continuous-wave (CW) RF signal to the tag; the tag responds by modulating the reflection coefficient of its antenna, thereby backscattering an information signal to the Interrogator. The system is ITF, i.e. a tag modulates its antenna reflection coefficient with an information signal only after being directed to do so by an Interrogator. This document specifies —   physical interactions (the signalling layer of the communication link) between Interrogators and tags; —   logical operating procedures and commands between Interrogators and Tags; —   the collision arbitration scheme used to identify a specific tag in a multiple-tag environment; —   optional security commands that allow the use of crypto suites of ISO/IEC 29167.

The present document:
1) Specifies a JSON [1] format for AdES signatures (JAdES signatures hereinafter) built on JSON Web
Signatures (JWS hereinafter) as specified in IETF RFC 7515 [2]. For this, the present document:
- Extends the JSON Web Signatures specified in IETF RFC 7515 [2] by defining an additional set of
JSON header parameters that can be incorporated in the JOSE Header (either in its JWS Protected
Header or its JWS Unprotected Header parts). Many of these new header parameters have the same
semantics as the attributes/properties defined in CAdES [i.2] and XAdES [4] digital signatures. Other
header parameters are defined to meet specific requirements that current JSON Web Signatures cannot
meet (e.g. for explicitly referencing detached JWS Payload). These new header parameters and their
corresponding types are defined in a JSON schema.
- Specifies the mechanisms for incorporating the aforementioned JSON components in JSON Web
Signatures [2] to build JAdES signatures, offering the same features as CAdES and XAdES in JSON
syntax, and therefore fulfilling the same requirements (such as the long-term validity of digital
signatures).
2) Defines four levels of JAdES baseline signatures addressing incremental requirements to maintain the validity
of the signatures over the long term. Each level requires the presence of certain JAdES header parameters,
suitably profiled for reducing the optionality as much as possible. The aforementioned levels 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.
EXAMPLE: An example of requirements raised in specific domains is signing HTTP messages exchanged by
parties in certain environments, which require signing both the HTTP body and some specific http
headers. The format specified in IETF RFC 7515 [2] does not provide any native mechanism for
individually identifying a detached JWS Payload. Clause 5.2.8 of the present document defines
sigD, a new JSON header parameter that allows to identify one or more detached data objects
which, suitably processed and concatenated, form the detached JWS Payload.
Procedures for creation, augmentation, and validation of JAdES digital signatures are out of scope.
NOTE 1: ETSI EN 319 102-1 [i.3] specifies procedures for creation, augmentation and validation of other types of
AdES digital signatures.
The present multi-part deliverable aims at supporting electronic signatures independent of any specific regulatory
framework.
NOTE 2: Specifically, but not exclusively, it is the aim that JAdES digital signatures specified in the present
multi-part deliverable can be used to meet the requirements of electronic signatures, advanced electronic
signatures, qualified electronic signatures, electronic seals, advanced electronic seals, and qualified
electronic seals as defined in Regulation (EU) No 910/2014 [i.1].

This document specifies the syntax and semantics of video usability information (VUI) parameters and supplemental enhancement information (SEI) messages. The VUI parameters and SEI messages defined in this document are designed to be conveyed within coded video bitstreams in a manner specified in a video coding specification or to be conveyed by other means determined by the specifications for systems that make use of such coded video bitstreams. This document is particularly intended for use with coded video bitstreams as specified by Rec. ITU‑T H.266 | ISO/IEC 23090-3, although it can also be used with other types of coded video bitstreams. VUI parameters and SEI messages can assist in processes related to decoding, display or other purposes. However, unless otherwise specified in a referencing specification, the interpretation and use of the VUI parameters and SEI messages specified in this document is not a required functionality of a video decoder or receiving video system. Although semantics are specified for the VUI parameters and SEI messages, decoders and receiving video systems can simply ignore the content of the VUI parameters and SEI messages or can use them in a manner that somewhat differs from what is specified in this document.
