SMART TELEVISION –
Part 2: Framework of integrated service on smart television
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 63122-2, which is a technical report, has been prepared by subcommittee TA 1:

Terminals for audio, video and data services and contents, of IEC technical committee 100:

Audio, video and multimedia systems and equipment.

---------------------- Page: 10 ----------------------
IEC TR 63122-2:2019 © IEC 2019 – 9 –

reference model of smart television services. A smart television terminal that supports general

services needs to meet the following requirements.
1 2

• System: by installing a smart operating system, such as Android™ or iOS™ , a user may

freely install and uninstall application programs provided by third-party service providers

and voluntarily select to accept or expand services, etc.; the user may extend the

functions of a traditional television with installed programs, realize somatosensory games,

software downloads and installation, multi-screen interaction and voice operation, thereby

conducting service for intensive users across regions. The system has a relatively high

reliability and availability.

• Openness: openness and consistence in terms of service capacity, service size, network

size, user access mode, service access mode and device interconnection. An open
platform allows infinite extension of content and applications.

• Mode of delivery: a smart television service may be delivered through smart interactive

means, such as voice control and gesture interaction. Such means are important for

service improvement and expansion. It can realize integration and interaction of
information, entertainment, application and message on the television screen.
4.1.2 Service industrial chain
General smart television service offers the following features.

• One-way interactive information flow: allows the user to search and interact with

information, including data flows mainly consisting of audio-video and allows the user to

control information mainly containing smart interaction, transformation of traditional one-

way viewing into two-way interaction mode, and provide the content along with the

appropriate service mode. See Annex B for the typical smart interaction model.

• Provision of streaming service: content cache, distribution and storage. Underpinning

"content first", smart home entertainment terminals are becoming the new focus of the

development trend of smart television. In consideration of the high level of popularization

and development of traditional television, consumption of new smart television is aimed at

providing users with funded content services. Current smart television terminals are in

strict compliance with the principle of high-level integration between hardware and content

in terms of interaction mode, multi-screen interaction and application content download.

See Annex E for the typical technical application of smart television.

• Provision of enriched and diversified video/audio resources, entertainment application

platforms and content services: smart television developers are encouraged to actively

build a unique ecological system, and launch novel content based on consumption habits

and actual demand for smart television, thereby creating an ecological system and profit

mode truly exclusive to smart television.

Based on the current development of smart television, the industrial chain of smart television

services mainly consists of the following components as shown in Figure 1.

Figure 1 – Model of service industrial chain

• Content provider: the content provider is mainly responsible for the production of content

for smart television terminals and the development of various application programs. It

provides the content as produced and developed to the service operator. The content

provider is the production origin of the entire service industrial chain and integrate the

content into a uniform platform of the service operator to allow the content to be used by

end user terminals by reaching consumers via smart television terminals. The content

provider has the following main responsibilities:
1) to provide new distribution channels for the content provider;

2) to request that the content be protected rather than being illegally disseminated and

used;

3) to ensure that the operations of audio/video content are manageable and billable;

4) to ensure that the operations of installable application programs are manageable and

billable.

• Service operator: the service operator is mainly responsible for the integration and

operations of the content. It also integrates various contents on its own platform and

reaches end consumers via the network of the network operator to offer appropriate

services and applications to users. The service operator has the responsibilities described

below:
1) to ensure normal operations of the service and carry out service management;

2) to guarantee such processes as content review and release and carry out content

management;

3) to guarantee user management and carry out account management for users, such as

account opening and cancellation;

4) to guarantee a certified authorization and billing mechanism during service use to

prevent illegal use of the service;

5) to safeguard the operations of the smart television terminal and carry out terminal

management;
6) to provide the user with a uniform service portal navigation;
7) to ensure that the network operator provides a transmission network with QoS
guarantee;
