AVM - Audio, video and multimedia systems and equipment

This part of IEC 60268 defines the STI model, test signals, measurement and prediction
methods.
The objective of this document is to provide a comprehensive manual for all types of users of
the STI model in the fields of audio, communications and acoustics.
This document does not provide STI criteria for certification of transmission channels (e.g.
criteria for a voice-alarm system), but some typical application values are provided in Annex G.
Every measurement method has limitations, and the reader is referred to clauses relating to
limitations such as speech privacy, echo and systems using digital voice compression
(vocoders).
This document does not cover the case of fluctuating noise on the STI, although some general
comments on dealing with this complex issue are provided in 7.13 and 8.9.3.

This part of IEC 60268 applies to transducers converting an electrical input signal into a
mechanical or acoustical output signal. However, if the electrical input terminals and the surface
of the radiator are accessible, this document can also apply to passive and active sound
systems such as loudspeakers, headphones, TV-sets, multi-media devices, personal portable
audio devices, automotive sound systems and professional equipment. This document
describes only electrical and mechanical measurements that help assess the transfer behaviour
of the device under test (DUT). This includes operating the DUT in both the small- and largesignal
domains. The influence of the target application's acoustical boundary conditions (e.g.
car interior) can also be considered in the physical evaluation of the sound system. Perception
and cognitive evaluations of the reproduced sound and the impact of perceived sound quality
are outside the scope of this document.
NOTE This document does not apply to microphones and other sensors. Implementation of this document does not
require access to the sound pressures generated in the near or far fields of the radiator. Directivity and other
characteristics describing the electro-acoustical transfer properties are described in IEC 60268-21, which covers
acoustical measurements.The practical application of the measurements for research and development (R&D), endof-
line testing (QC) and evaluation in the final target application (TA) is discussed in Annex A.

The Audio Device Class Definition applies to all devices or functions embedded in composite devices that are
used to manipulate audio, voice, and sound-related functionality. This includes both audio data (analog and
digital) and the functionality that is used to directly control the audio environment, such as Volume and Tone
Control. The Audio Device Class does not include functionality to operate transport mechanisms that are
related to the reproduction of audio data, such as tape transport mechanisms or CD-ROM drive control.

This document specifies terminology and definitions related to wireless power transfer (WPT)
technologies below 30 MHz to promote global harmonization of wireless power transfer
terminology.
This document does not address terminology of wireless power transfer outside the scope of
IEC TC 100 (Audio, video and multimedia systems and equipment), such as human exposure
or safety.

This document is the Release 3.0 of this device class definition.

The intention of this document is to describe in detail all the Audio Data Formats that are supported by the
Audio Device Class. This document is considered an integral part of the Audio Device Class Specification,
although subsequent revisions of this document are independent of the revision evolution of the main USB
Audio Specification. This is to easily accommodate the addition of new Audio Data Formats without impeding
the core USB Audio Specification.

The USB Audio Device Class Definition for Basic Audio Functions applies to all USB Audio Functions that are
based on the Universal Serial Bus Device Class Definition for Audio Devices Release 3.0. It defines baseline audio
functionality for all ADC 3.0 compliant Hosts and Devices.

This part of IEC 60268 specifies an acoustical measurement method that applies to electroacoustical
transducers and passive and active sound systems, such as loudspeakers, TV-sets,
multi-media devices, personal portable audio devices, automotive sound systems and
professional equipment. The device under test (DUT) can be comprised of electrical
components performing analogue and digital signal processing prior to the passive actuators
performing a transduction of the electrical input into an acoustical output signal. This
document describes only physical measurements that assess the transfer behaviour of the
DUT between an arbitrary analogue or digital input signal and the acoustical output at any
point in the near and far field of the system. This includes operating the DUT in both the small
and large signal domains. The influence of the acoustical boundary conditions of the target
application (e.g. car interior) can also be considered in the physical evaluation of the sound
system. This document does not assess the perception and cognitive evaluation of the
reproduced sound and the impact of perceived sound quality.
NOTE Some measurement methods defined in this document can be applied to headphones, headsets,
earphones and earsets in accordance with [1]1. This document does not apply to microphones and other sensors.
This document does not require access to the state variables (voltage, current) at the electrical terminals of the
transducer. Sensitivity, electric input power and other characteristics based on the electrical impedance will be
described in a separate future standard document, IEC 60268-22, dedicated to electrical and mechanical
measurements.

This part of IEC 62087 specifies the determination of the power consumption of computer
monitors including, but is not limited to, those with CRT, LCD, PDP or OLED technologies.

document. This document is limited to computer monitors that are powered from a main power
source other than a battery. Computer monitors that are powered from a battery source are
not covered by this document. However mains-powered computer monitors may include any
number of auxiliary batteries.
Computer monitors connected by digital inputs such as DisplayPort, HDMI, DVI, or by
analogue VGA input, are considered in this document. This document does not apply to
network- and wirelessly connected computer monitors.
A computer monitor is a display device that does not include a TV tuner and is intended to be
used to display the video signals from a computer. These video signals are produced from
software programs that are operating within the computer and can consist of static and
moving images. As such, test procedures using static patterns, dynamic video and web-based
video are specified.
The test methods specified in this document can be applied to computer monitors of any size,
however, this document is not applicable to specialized monitors associated with medical
equipment, publishing and other professional, commercial or industrial uses.
The various modes of operation that are relevant for measuring power consumption are also
defined.
The measuring conditions in this document represent the normal use of the equipment and
can differ from specific conditions, for example as specified in safety standards.

IEC corrigendum

This document contains a list of currently used terminology to describe accessibility and terms
that writers of standards need when writing and designing International Standards. It is
important to standardize and define a recognized list of the terms already used and in existing
ITU Recommendations and Resolutions, along with those in the UN Convention on the Rights
of Persons with Disabilities (UNCRPD). Without such a list, there could be confusion not only
on the part of writers and implementers of standards, but also by the public at large. It is also
important to eliminate terminology that is no longer used, offensive, and demeaning to
persons with disabilities (PWD) and others.
The terminology in this document is for use in international work when English is used to refer
to telecommunication/ICT accessibility matters. This document is also applicable to everyday
life and all usages, including web design and other writings, as well as ICT,
telecommunications, and broadcasting standardization. The aim is for it to also be
mainstreamed into future policy, regulatory, and academic documents so as to be consistent
with global compatibility and understanding. In the future, work that is yet to be created,
written, or approved could include new terms that are added as appropriate by consensus in a
revision.
