Parasitic communication protocol for radio-frequency wireless power transmission (IEC 62980:2022)
EN IEC 62980:2022

This standard defines procedures for transferring power to non-powered IoT devices using the existing ISM band communication infrastructure and RF WPT and a protocol for a two-way, long-distance wireless network in which IoT devices and APs communicate using backscatter modulation of ISM-band signals. Three components are required for two-way, long-distance wireless communication using backscatter modulation of ISM-band signals: an STA that transmits wireless power and data packets to SSNs by forming ISM-band signal channels between HIE-APs, a batteryless SSN that changes the sensitivity of the channel signals received from the STA using backscatter modulation, and an HIE-AP that practically decodes the channel signals whose sensitivity was changed by the SSN. In this standard, the procedures for CW-type RF WPT using communication among these three components are specified based on application of the CSI or RSSI detection method of ISM-band communication.
This standard proposes a convergence communication protocol than can deploy sensors, which can operate at low power (dozens of microwatts or less) without batteries, collect energy, and perform communication, to transmit power to SSNs using RF WPT based on parasitic communication. This method can be applied to application service areas such as domestic IoT, the micro-sensor industry, and industries related to environmental monitoring in the future

Cable networks for television signals, sound signals and interactive services - Part 101-2: Performance requirements for signals delivered at the system outlet in operation with all-digital channels load
SIST EN IEC 60728-101-2:2023

IEC 60728-101-2:2023 provides the minimum performance requirements to be fulfilled in operation at the system outlet or terminal input and describes the summation criteria for the impairments present in the received signals and those produced by the CATV/MATV/SMATV cable network, including individual receiving systems. In a building divided into apartment blocks, the signals received by the antennas are distributed by the MATV/SMATV cable network up to the home network interface (HNI); the television signals are then distributed (inside the home) by home networks (HN) of various types up to the system outlet or terminal input. The cable network can support two-way operation, from the system outlet (or terminal input) towards the headend. The home network can use coaxial cables, balanced pair cables, fibre optic cables (glass or plastic) and also wireless links inside a room (or a small number of adjacent rooms) to replace wired cords. This part of IEC 60728 is limited to downstream TV broadcast signals received from antennas and is applicable to cable networks intended for television signals, sound signals and interactive services operating between about 5 MHz and 3 300 MHz. The frequency range is extended to 6 000 MHz for home distribution techniques that replace wired cords with a wireless two-way communication inside a room (or a small number of adjacent rooms) that uses the 5 GHz to 6 GHz frequency band. The main sections of a general CATV/MATV/SMATV system, indicating the parts of the IEC 60728-101 series documents where the relevant performance requirements are indicated. - The requirements for the signals received at the headend are given in IEC 60728-101:2016, Clause 6. - The requirements for the CATV/MATV/SMATV cable network, assuming an unimpaired input signal at the input of the headend, up to the system outlet are given in IEC 60728‑101:2016, Clause 5. - The requirements for the CATV/MATV/SMATV cable network up to the home network interface (HNI) are given in IEC 60728-101:2016, Clause 7, assuming an unimpaired input signal at the input of the headend. - The specific requirements from HNI to the system outlet or terminal input are given in IEC 60728-101-1:2023, Clause 5, assuming an unimpaired input signal at the HNI. - The requirements at the system outlet in operation are given in Clause 6 of this document. The expression "in operation" means that the received signals, with their impairments, are applied to the headend input of the CATV/MATV/SMATV cable network. The requirements at the system outlet "in operation" are derived, therefore, by summing the impairments of the various cascaded parts of the system and of the input signal. When a change of signal format from digital to digital (e.g. from QPSK to QAM) (e.g. as in ETSI EN 300 473) or from digital to analogue (e.g. from DVB-S/S2 to AM-VSB or DVB-T/T2 to AM-VSB) is made at the headend, the summation of the impairments that produce a relaxation of requirements at system outlet does not apply. Such a case will be the equivalence of unimpaired signals applied at the headend input. Therefore, the requirements at system outlet given in IEC 60728‑1 apply. This document also provides references for the basic methods of measurement of the operational characteristics of the downstream cable network in order to assess its performance. All requirements refer to the performance limits to be achieved in operation at any system outlet when terminated in a resistance equal to the nominal load impedance of the system, unless otherwise specified.

Cable networks for television signals, sound signals and interactive services - Part 101-1: RF cabling for two-way home networks with all-digital channels load
SIST EN IEC 60728-101-1:2023

IEC 60728-101-1:2023 provides the requirements and describes the implementation guidelines of RF cabling for two-way home networks; it is applicable to any home network that distributes signals provided by CATV/MATV/SMATV cable networks (including individual receiving systems) having a coaxial cable output. It is also applicable to home networks where some part of the distribution network uses wireless links, for example in place of the receiver cord. This part of IEC 60728 is therefore applicable to RF cabling for two-way home networks with wired cords or wireless links inside a room and primarily intended for television and sound signals operating between about 5 MHz and 3 300 MHz. The frequency range is extended to 6 000 MHz for distribution techniques that replace wired cords with a wireless two-way communication inside a room (or a small number of adjacent rooms) that uses the 5 GHz to 6 GHz band. In a building divided into apartment blocks, the distribution of the signals inside the home starts from the home network interface (HNI) up to the system outlet or terminal input. The requirements at the system outlet are given in IEC 60728-101:2016, Clause 5 and the requirements at the HNI are given in IEC 60728-101:2016, Clause 7. In Clause 5 of this document, additional requirements are given. This document deals with various possibilities to distribute signals in a home network, using coaxial cables, balanced pair cables, fibre optic cables (glass or plastic) and also wireless links inside a room (or a small number of adjacent rooms) to replace wired cords. This document gives references to basic methods of measurement of the operational characteristics of the home cable network in order to assess its performance. All requirements refer to the performance limits, which are obtained between the input(s) at the home network interface (HNI) and the output at any system outlet when terminated in a resistance equal to the nominal load impedance of the system, unless otherwise specified. Where system outlets are not used, the above applies to the terminal input. The present document also provides limits for the accumulation of degradations if the home network is subdivided into a number of parts, using different transmission media (e.g. coaxial cabling, balanced cabling, optical cabling, wireless links). Clause 5 defines the performance limits measured at system outlet or terminal input for an unimpaired (ideal) test signal applied at the HNI. Under normal operating conditions for any digital channel and meeting these limits, the cumulative effect of the impairment of any single parameter at the HNI and that due to the home network produces signals not worse than the requirements given in IEC 60728-101-2. For digitally modulated signals, the quality requirement is a QEF (quasi error-free) reception. This document describes the physical layer connection for home networks. Description of protocols required for layer 2 and higher layers is out of the scope of this document. Logical connections between devices within the home network are therefore not always guaranteed. This International Standard is to be used in conjunction with IEC 60728-101:2016.

Dynamic metadata high dynamic range impacts on TV power consumption

IEC TR 63449:2023 presents a study of the impact of high dynamic range (HDR) technologies with "dynamic metadata" on TV luminance and power consumption. It compares the power consumption of content with dynamic metadata to the same content without dynamic metadata. Non-dynamic "static metadata" HDR technologies such as HDR10 and non-metadata HDR such as HLG, were previously studied in IEC TR 63274:2021.
This document also reviews the current HDR TV market and analyses existing HDR TV power measurement methods and considerations for any changes to those power measurement standards.
While this document studies the results of content that include Dolby Vision® and HDR10+ dynamic metadata, any comparison of these two technologies is outside of the scope of this document.

IEC TR 61292-4:2023 is available as IEC TR 61292-4:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC TR 61292-4:2023 which is a Technical Report, applies to all commercially available optical amplifiers (OAs), including optical fibre amplifiers (OFAs) using active fibres as well as Raman amplifiers. Semiconductor optical amplifiers (SOAs) using semiconductor gain media are also included. This document provides informative guidelines on the threshold of high optical power that can cause high-temperature damage of the fibre. Also discussed is optical safety for manufacturers and users of optical amplifiers by quoting parts of existing standards and agreements on eye and skin safety. This document identifies the following values for maximum permissible optical power in the optical amplifier for damage-free and safe operation:
- the optical power limit that causes thermal damage to the fibre, such as fibre fuse and fibre-coat burning;
- the maximum permissible exposure (MPE) to which the eyes/skin can be exposed without consequent injury;
- the optical power limit in the fibre that causes MPE on the eyes/skin after free-space propagation from the fibre;
- the absolute allowable optical power level for damage-free and safe operation of the optical amplifier by comparing a) and c).
The objective of this document is to minimize potential confusion and misunderstanding in the industry that can cause unnecessary alarms and hinder the progress and acceptance of advancing optical amplifier technologies in the market. It is important that the reader always refers to the latest international standards and agreements, because the technologies concerned are rapidly evolving. The present document will be frequently reviewed and updated in a timely manner by incorporating the results of various studies related to OAs and OA-supported optical systems. This fourth edition cancels and replaces the third edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition.
a) The technical information has been updated to reflect revisions of the relevant references.
b) In particular, the descriptions provided in Clause 5 and Clause 6 have been modified significantly to reflect changes in the cited references. Unnecessary formulas and explanations that overlap with the references have been removed to simplify the document.
c) New information has been added to Annex A on optical fibre burning when light enters an optical fibre with a bubble train formed by a fibre fuse.

Service diagnostic interface for consumer electronics products and networks - Implementation for ECHONET

IEC 62394:2022 specifies requirements for service diagnostic software to be implemented in products that incorporate a digital interface. It does not specify requirements for carrying out remote diagnosis or for manufacturer-dependent software.
The Service Diagnostic Interface (SDI) requires an external controller (exclusive or general-purpose/PC) into which service diagnostic software can be loaded. Parts of the controller software are standardized while other parts are proprietary to the manufacturers.
To reach a common approach in servicing all products from all manufacturers, it is necessary to standardize specific items to be tested in products and certain aspects of controllers' diagnostic software.
The SDI is based upon ECHONET specification version 2.11, ECHONET Lite specification version 1.13, and APPENDIX Detailed Requirements for ECHONET Device objects Release M, because this interface will be used in future products. The use of this connection and existing communication protocols enable implementation in products at a low cost, with maximum flexibility and efficiency.
The SDI consists of
• specific hardware and software requirements of the device under test (DUT);
• specific requirements of the controller:
– the service software;
– an ECHONET interface;
• the connection between the controller and the DUT.
This document provides the minimal requirements necessary to carry out computerized diagnosis. It covers the standardized software of the controller as well as the standardized software and provisions in the DUT.
IEC 62394:2022 cancels and replaces the third edition published in 2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) updates of the device object super class specifications for the property configurations shared by all device objects;
b) modification and addition of the property configurations defined by each object;
c) addition of new device objects and their property configurations;
d) updates to Bibliography.

Cable networks for television signals, sound signals and interactive services - Part 115: In-building optical systems for broadcast signal transmissions
SIST EN IEC 60728-115:2022

This part of IEC 60728 is applicable to in-building optical transmission systems for broadcast signal transmission that consist of optical transmitter, optical amplifiers, splitters, V-ONUs, etc. These systems are primarily intended for television and sound signals using digital transmission technology. This document specifies the basic system parameters and methods of measurement for in-building optical distribution systems between building network interface (BNI) and home network interface (HNI) in order to assess the system performance and its performance limits. This document is also applicable to broadcast signal transmission using a telecommunication network if it satisfies the requirements of optical section of this document. This document describes RF transmission for fully digitalized broadcast and narrowcast (limited area distribution of broadcast) signals over an FTTH network and introduces xPON system as a physical layer media. The detailed description of the physical layer is out of the scope of this document. The scope is limited to RF signal transmission over optical network, thus, it does not include IP transport technologies, such as IP Multicast and associate protocols. This standard specifies the required system performance of all-optical building networks in order to connect with FTTH networks which are defined by IEC60728-113 and IEC60728-13-1. Use of In-building optical networks is very effective for saving cost (installation and maintenance) and enabling future network up-grades, especially in huge apartment buildings. In this document, the optical wavelengths and electrical frequency bands listed in Table 1 - and Table 2 - are considered to be used. [Table 1 and Table 2]
