CONCEPTUAL MODEL FOR TC 100 STANDARDIZATION
ON MULTIMEDIA CYBER TECHNOLOGY
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

The main task of IEC technical committees is to prepare International Standards. However, a

technical committee may propose the publication of a Technical Report when it has collected

data of a different kind from that which is normally published as an International Standard, for

example "state of the art".

IEC TR 63289, which is a Technical Report, has been prepared by IEC technical committee

100: Audio, video and multimedia systems and equipment.
The text of this Technical Report is based on the following documents:
Draft TR Report on voting
100/3442/DTR 100/3468/RVDTR

Full information on the voting for the approval of this Technical Report can be found in the

report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

INTRODUCTION

IEC TR 61998:2015, Model and framework for standardization in multimedia equipment and

systems, has already described cyber world applications and at the present time, some CE

products with Internet service are starting to use these cyber world applications. TC 100 has

only a few standards regarding this cyber world application up to now; however, now and in the

future, TC 100 standardization must shift into cyber-physical systems.

"Study Session 10 – Multimedia cyber technology" was established to consider the cases of the

multimedia cyber technology, including IoT or CPS, within the scope of TC 100, and proposes

study items. This Technical Report explains these SS 10 studies and shows the possible future

works of CPS within the scope of TC 100.

4 Cyber-physical system in TC 100

The CPS model in this document is illustrated in Figure 1. A provider manages contents or

services in the physical world. A provider distributes data for contents or services with cyber-

physical technology. The data reaches users via a network with information technologies. The

user receives contents or services with cyber-physical technologies.
The meaning of CPS, IT and IoT are generally thought of as follows:
---------------------- Page: 9 ----------------------
– 8 – IEC TR 63289:2020 © IEC 2020

• CPS is a system to improve efficiency of all systems, create new services and improve

productivity by collecting data obtained from the physical world into cyber world, by

processing and utilizing the data.
• IT is a technology related to computers and data communications.

• IoT is a mechanism of mutual control, not only through information and communications

equipment, such as computers, but also through various objects existing in the physical

world have a communication function, connect to the Internet and communicate with each

other.
Figure 1 – Cyber-physical system model

The model from IEC 61998:2015 describes the entire system and includes CPS as shown in

Figure 2. Equipment and systems in the TC 100 model exchange data through the network with

the data source. The TC 100 model also shows a variety of domains such as home, car and

mobile.
---------------------- Page: 10 ----------------------
IEC TR 63289:2020 © IEC 2020 – 9 –
Figure 2 – TC 100 model from IEC 61998:2015

Figure 3 shows the relation between the TC 100 model and the user. This explains what causes

a communication between the TC 100 model and the user; this communication is established

by human senses. Audio and visual communication are the primal human senses, and other

senses can communicate with the TC 100 model also.
Figure 3 – TC 100 model and user communication from IEC 61998:2015

From all these models, the important essence of the TC 100 model is communication with a

user resulting in a physical phenomenon. Equipment, a device or means that communicates

with the physical world is a physical world entity because the user and the physical phenomenon

exist in the physical world. All other equipment, devices or means can be cyber world entities.

---------------------- Page: 11 ----------------------
– 10 – IEC TR 63289:2020 © IEC 2020

This is the most important situation for TC 100: the legacy standardization items, such as

devices and equipment that are physical entities, are replaced with cyber entities.

Current status of activities related to CPS in TC 100 is illustrated in Figure 4. The application

area is not standardized yet. The platform and wide area network are standardized in other

standard developing organizations. IEC TC 100 TA 18 has standardized some local area

network area items, such as Network configuration. Each TA has standardized many devices.

Figure 4 – Current status of activities related with cyber-physical system

In this scheme, the provider can provide not only data but also cyber equipment and cyber

systems of TC 100. For instance, raw audio data can be processed to be amplified, tone

controlled, filtered and edited in cyber world by cloud computing. Therefore, the only physical

device that user needed is receiving data and reproducing it; any other function can be done in

the cyber world. This cyber world functionality will be done by cloud services such as SaaS

(Software as a Service), PaaS (Platform as a Service) and IaaS (Infrastructure as a Service).

For instance, services for audio and video are described in Clause 5.
5 Cases of audio and video services
5.1 General

Audio and video services are provided with IoT/CPS technologies, such as video/audio

streaming, video/audio on demand, download, cloud storage and others. Firstly, home music

service is studied as a typical TC 100 system case. Home video services and CPS are also

studied to investigate the standardization area of multimedia cyber technology in TC 100.

5.2 Home music service

A typical music listening scene with CPS is shown in Figure 5. A music service provider offers

its music through the network. Users can buy or subscribe to the music service and listen to it

on several audio devices. Users may also upload the user’s music content to the server and

unify the management of the contents. Furthermore, content editing or modification will be done

in the cyber system.
---------------------- Page: 12 ----------------------
IEC TR 63289:2020 © IEC 2020 – 11 –

Currently, the service is providing audio content only; other information of the service is quite

limited. For instance, the jacket picture is provided but no liner notes and related information.

There could be more information services that link to other services.
Figure 5 – Typical music-listening scene

The primary clients of user devices in the past and now are the following components: the player,

the STB (Set Top Box) and the AV amplifier, loudspeaker or headphone, monitor device,

microphone, camera and other interface devices as shown in Figure 6. The data of the content

came from disc media.
---------------------- Page: 13 ----------------------
– 12 – IEC TR 63289:2020 © IEC 2020
Figure 6 – The primary client in the past and now

Figure 6 shows an example of audio systems and equipment for consumer, and each element

is related to the activities in TC 100. These are that DRM of contents is specified by TA 18, the

specifications related with speakers are managed in TA 20, the technologies of digital interface

of audio devices are specified by TA 4 and TA 20, the technologies related to energy efficiency

are specified in TA 19, the technologies related to PC are specified by TA 18.

When a music service of CPS becomes widely used, the primary client will consist only of the

following components: smart phone, smart watch, PC and amplifier, loudspeaker or headphone,

monitor device, microphone, camera and other interface devices. There will be no player,

receiver, STB as shown in the prediction or latest reality in Figure 7.
---------------------- Page: 14 ----------------------
IEC TR 63289:2020 © IEC 2020 – 13 –
Figure 7 – The primary client now and the future

The user’s client device will be such devices as PC/tablets and smartphones, or devices based

on PC and smartphone architecture. Players and STBs will be not used, but the key

reproduction devices such as DACs, digital amplifiers, monitors, and loudspeakers will continue

to be used.

The electronic distribution of music via cloud services spreads instead of physical media

distribution such as CDs. Furthermore, high-resolution audio more than CD is distributed

through the network to maximize user experience. In a multi-room use case, when the user

listens to music and moves to another room, the configuration of speakers is deferent with each

room. Therefore, rendering of audio is required for each room. In a mobile use case, a user can

listen to audio everywhere and regardless of location, for example with a mobile device or

mobile phone to play content from cloud server or home server system.

Digital processing of audio data is required to fit the user environment more efficiently for such

a speaker layout or listening position, and for compensation of the reproduction capability of

the device. To gather each device's information for the data processing, a unified method and

data structure is helpful.

Currently, there is also no universal scheme for all kinds of such cyber domain services. If users

want to access the information regarding audio content, such as liner notes or content

information, there is no such universal method for accessing these services.

The entity of content and service in cyber system is such as SaaS, PaaS and IaaS, they base

on software and IT technologies. On the other hand, a physical system has disadvantages in

that it requires physical manufacturing and maintenance, which requires physical work and cost.

Therefore, only a small part of high-end audio systems will exist in a physical system. This

cyber system will make consumer disc media and player disappear, and also, the user may not

need to keep physical media of music in home, most of content will exist in the cyber system.

5.3 Home video service

Video service in CPS has also spread quickly. Electronic sell through or streaming video service

has become popular instead of media distribution, such as video tape or DVD. Video service

has different requirements than music service.
---------------------- Page: 15 ----------------------
– 14 – IEC TR 63289:2020 © IEC 2020

There are many types of video devices, video browsers and video formats. It is very hard to

develop home video systems to support all of these formats. Owing to the difference of display

resolution or type of network, it is required to transform video data to fit the user’s environment.

Video data is bigger than music data, generally. Faster and wideband network is required for

better quality. When the user downloads video data, it takes a long time and the device needs

a large local memory to store or cache it.

To establish a high-quality home video service, the following needs to be considered:

– Quality of network: when packets in the network are lost often, the playback of video is

interrupted.

– Bandwidth of network: high-resolution video requires high bit encoding and transfer rate.

– Latency of network: if latency of network is not small, it needs a longer time to respond when

the user makes an interaction as a user operation.

– Efficient video compression and coding method: for quality, function, and data reduction.

Copyright management is one of key issues for video service. Video content, especially movies,

requires a highly copyright-protected system, so that should be considered. Currently several

methods, such as contract basis or technical encryption, are used for copyright management.

On the other hand, existing video content on video tape or DVD that the user obtained cannot

be transformed to cyber-domain data because of copyright; it may need to be solved. IEC 62919,

Content management – Monitoring and management of personal digital content, could be one

solution; such a standard to use cyber content is required.

And, cyber security is another key issue, a standard for which, from the viewpoint of TC 100's

scope, is needed.
5.4 Car audio and video system

The different aspect is that the car system is movable on road and land, and autonomous. The

characteristics of a car system are as follows:
• movable and autonomous, with its own energy supply,

• a car has various working and functional modes, car AV and multimedia system works

depending on the condition of the car such as drive, cruise, stop, park and refuel or charge,

• users are drivers, passengers, pedestrians in and around the car, and remote users of the

car's AV and multimedia system.

These aspects affect AV and multimedia systems; however, networked AV and multimedia

systems can take advantage of CPS to correspond to these aspects.

The CPS of car AV systems has been introduced with mobile networks; therefore, there is a

limitation of network ability. Audio content in the cyber world can be played back with good

quality. Video content stored in a mobile phone can be played on a display with which the car

is equipped. The current typical CPS car audio system consists of a car main AV device and

smartphone as shown in Figure 8. This system may provide not only AV, but also navigation

and many Internet services.
---------------------- Page: 16 ----------------------
IEC TR 63289:2020 © IEC 2020 – 15 –
Figure 8 – Car audio systems consist of car main AV device and smartphone

Currently, this system depends on smartphones, therefore its function and specification also

depend on a smartphone. To obtain a more integrated system with car and other AV and

multimedia systems, for example, IEC 63246, Multimedia systems and equipment for cars –

Configurable Car Infotainment Services (CCIS), is under development. CCIS provides an

integrated car AV and multimedia system with other AV and multimedia systems and car

systems, and controls the whole system including CPS. Figure 9 shows CCIS.
Figure 9 – CCIS
Furthermore, many CPS services for cars are on the way. For example:
– HUD+AR will be popular soon;
– digit
