SMART TELEVISION –
Part 1: Conceptual model for 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 63122-1, 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.The text of this technical report is based on the following documents:

INTRODUCTION
This part of IEC 63122 discusses the background of cloud computing, the Internet, the mobile
Internet industry, the principle of open innovation, the vertical integration of the industry chain,
technology and encourages the digital TV (television) industry to seize the opportunity to
upgrade and strengthen innovation in smart television technology. The innovations of business
models and institutional mechanisms will be explored, and we will explain how acceleration is
needed to broaden the application market and put forward the concept of smart television
models and standardization needs.The reception of digital TV and high-definition broadcasting in the home has recently been well
established for various areas. Internet TV and delivery of multimedia content to the user at home,
via the Internet, are also becoming increasingly common.Smart television systems are intended to extend the reach of multimedia content to the TV set in
a seamless, viewer-friendly manner. The viewer can more conveniently access both broadcast
digital content and Internet multimedia content on a TV set using a single user-interface device
and a single on-screen interface.There are three major key factors leading smart television development. Lifestyle changes from
the user side, the building of network infrastructure according to the rapid development of wired
and wireless networks, and the emergence of TV alternatives.An individualized lifestyle accelerates personalization and customization of contents, and the
experience from other smart electronic devices drives the user to long for the smart television as
the core of entertainment at home.The rapid development of high-speed Internet access and the emergence of home network
techniques assigning an IP address to electronic devices will make TV smarter.In addition, the market requires a change from TV to smart television because of the emergence
of TV alternatives, such as the tablet, the smartphone and the media player.---------------------- Page: 8 ----------------------
