- USB Type-C receptacles, including electro-mechanical definition and performance requirements;
- USB Type-C plugs and cable assemblies, including electro-mechanical definition and performance requirements;
- USB Type-C to legacy cable assemblies and adapters;
- USB Type-C-based device detection and interface configuration, including support for legacy connections;
- USB Power Delivery optimized for the USB Type-C connector.

 

 

IEC 62702-1-2 Ed.1.0 (2017-11) Audio archive system - Part 1-2 : BD disk and data migration for long-term audio data storage

specifies a method of data-quality assurance for writable disks which are specified for long-term data storage, and a data migration method, which can sustain the recorded data on disks for long-term audio data preservation. The writable disks include Blu-ray Disk (BD) Recordable disk and BD Rewritable disk.
This document specifies the physical and logical aspects for a standard of audio archives of various storage types which are typically used for audio archives in markets.
The IEC 62702 series consists of:
- IEC 62702-1, which specifies the minimum requirements on physical aspects of optical disks for digital sound recordings; IEC 62702-1-1 specifies requirements for DVD optical disks, IEC 62702-1-2 specifies requirements for BD optical disks.
- IEC 62702-2, which specifies the minimum requirements for digitization of content, format of digitized content, content information and media inspection.

 

 

IEC 62919:2017 Ed.1.0 (2017-11) Content management - Monitoring and management of personal digital content

specifies the requirements, protocol and the data format to visualize personal content saved on various devices, such as mobile phones, music players, personal computers, hard disk recorders and e-book devices.  It also specifies methods for gathering information of digital content saved on personal devices and shared within a group, and to extract the gathered information by a uniform application interface.

 


 

IEC 62731:2018 Ed.2.0 (2018-01) Text-to-speech for television - General requirements

specifies the text-to-speech functionality for a (broadcast) receiver with a text-to-speech system. Such a system may be one device, i.e. a receiver with an integrated text-to-speech generator, or may be two devices, i.e. a receiver interfacing with an external text-to-speech device. This document applies only to completely functional stationary (or semi-stationary) digital TV receivers such as set top boxes, integrated digital TVs, recorders and other products whose primary function is to receive TV content. Where this document refers to TV, this will be shorthand for all such receivers.
This document does not apply to products that are capable of receiving TV as a secondary function (e.g. PCs or game consoles with digital television receivers). It also does not apply to sub-assemblies (e.g. PC tuner cards).
This edition includes the following significant technical changes with respect to the previous edition:
a) in 6.2, the levels of announcement quality were revised as well as considerations for ways in which device users can provide service providers with feedback on incorrectly announced terms.
b) in 6.3, the following TV functionality was added: the TV can receive updated words, associated conversions and updated conversion rules for the TTS engine via a network connection.

 

 

IEC 60728-2:2018 Ed.3.0 (2018-01) Cable networks for television signals, sound signals and interactive services - Part 2: Electromagnetic compatibility for equipment

applies to the radiation characteristics and immunity to electromagnetic disturbance of EM active equipment (active and passive equipment) for the reception, processing and distribution of television, sound and interactive multimedia signals as dealt with in IEC 60728-3, IEC 60728-4, IEC 60728-5 and IEC 60728-6.
This document covers the following frequency ranges:
- disturbance voltage injected into the mains: 150 kHz to 30 MHz;
- radiation from active equipment: 5 MHz to 25 GHz;
- immunity of active equipment: 150 kHz to 25 GHz;
- screening effectiveness of passive equipment: 5 MHz to 3,5 GHz.
This document specifies requirements for maximum allowed radiation, minimum immunity and minimum screening effectiveness and describes test methods for conformance testing.
This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Frequency extensions:
a.1) The upper frequency limit of conventional cable network equipment was extended from 862 MHz to 1 000 MHz due to market demands.
a.2) The first intermediate frequency range (1st IF range) for satellite signal transmission was extended to cover now frequencies from 950 MHz up to 3 500 MHz.
a.3) The methods of measurement and the EMC requirements in the overlapping frequency range from 950 MHz to 1 000 MHz were allocated in relation to the upper frequency limit, 1 000 MHz, and the lower frequency limit, 950 MHz, of the relevant equipment under test.
b) New EMC environment in the 800 MHz band:
b.1) The European Commission has requested CENELEC and ETSI to draft immunity requirements for equipment, to protect against disturbance from the new wireless service in the 790 MHz to 862 MHz band.
b.2) A CENELEC/ETSI Joint Working Group “Digital Dividend” was formed to describe the new EMC environment and to advise on appropriate test methods and limits.
b.3) IEC 60728-2 is the document specifying immunity requirements for active and passive cable network equipment.
b.4) The method of measurement and the requirements for in-band immunity were extended taking into account this new EMC environment due to the allocation of broadband wireless services in the frequency band 694 MHz to 862 MHz. As a consequence, the limits of in-band immunity were specified for analogue and additionally for digital signals in this frequency range.
b.5) Consequently it is recommended, that, where cable networks and wireless networks coexist, only the transmission of digitally modulated signals should be used in the frequency range 694 MHz to 862 MHz.
b.6) For passive equipment, Class A and Class B specifications were kept in the standard but a note was added recommending that only Class A equipment should be used in the planning and implementation of new networks.
c) The methods of measurement for all kinds of indoor antennas were combined in the new 4.9.
d) A Bibliography has been added at the end of the document referencing, for example, CEPT Report 30 on “The identification of common and minimal (least restrictive) technical conditions for 790-862 MHz for the digital dividend in the European Union”.

It is not a performance standard. Recommendations for interfaces for equipment used in vehicles, and for analogue video interfaces for broadcast and similar equipment, are not given. Refer to IEC 60958 for the interconnection of digital signals. This third edition cancels and replaces the second edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) electric tolerance is standardized;
b) recommended value of output source impedance is adjusted;
c) value of 6 Ohms is additionally recommended to impedance-defined loudspeaker systems;
d) values in each table are chosen with respect to the state of the art and representative of best practice in industry.
