This document specifies various service industry models, various service descriptions and
management system frameworks for smart television services, and offers technical guidance
and standard specifications for the development and progress of smart television services.
This document also specifies data models and technical definitions of smart television
services and puts forward a technical specification for the purpose of further specifying a

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.

4.1.3 Hierarchical architecture
4.1.3.1 General description
The hierarchical architecture for a general smart television service mainly consists of the
parts described in 4.1.3.2 to 4.1.3.5. Interconnection between different layers may be realized
by the calling mode of functional modules of loose coupling. Intra-layer may also adopt the
structure of a functional module. See Figure 2.

Figure 2 – Model of hierarchical architecture

– 12 – IEC TR 63122-2:2019 © IEC 2019
4.1.3.2 Access layer
The access layer of a general smart television service uses IP as its basic protocol. It
includes broadband access network, urban area network and a backbone network, as well as
related control management functions. The access layer can be capable of ensuring sufficient
bandwidth and a certain transmission quality and be provided with the following capacities:
• access to the end-user terminal and certification of network layer;
• delivery of each service information stream to the destination end as required by the
previous layer;
• calling up network resources as per specific attribute requirements of each service to
ensure the function and performance of the service;
• satisfying the special requirements of the streaming media service for access layer;
• satisfying the network access requirements for the installation of application programs;
• monitoring of network administration functions and system equipment.
4.1.3.3 Management control layer
Being responsible for the service execution and control, the management control layer may
accept the bottom-layer network function of the access layer and provide service to the
application layer. It has the following functions:
• distribution and storage management of media content data, and content management of
application program data;
• service subscription and service statistics collection;
• realization of hierarchical level networking and internal load balance mechanism of
streaming server;
• provision of streaming service capability to the end user and support and service to end-
user applications;
• information maintenance of various services, i.e. one or more content combination.
• packaging of service capacity of the access layer, providing interface to the previous
application layer;
• provision of interface with such external systems as the billing system, user management
system and network management system.
4.1.3.4 Application layer
By calling up various capacities of the management control layer, the application layer
provides end-user terminals and content providers with various services. For instance, video
on demand applications and video-based broadcast remote education applications need a
basic streaming service capacity, although the service package pattern and service
processing logic representation between both applications are different. The application layer
needs to use the capacity provided by the service layer and execute application customization
and service deployment as required by the operator. It may offer the following features:
• providing the user with a uniform interface and carrying out operations such as service
ordering and data inquiry;
• acquiring content metadata and content pricing strategy provided by the content provider.
4.1.3.5 Interactive layer
The layer directly connecting the end-user terminal is located at the top end of the
hierarchical architecture, mainly providing customer-facing interaction with the user. End-user
terminals may have access to the network via such access means as ADSL, LAN and WLAN,
realize relevant services and offer the following features:
• processing user entry, identifying user's intention and getting user's feedback;

• processing two-way interactive data services and transmitting data to application level.
4.1.4 Model of service data
4.1.4.1 Service metadata
Smart television service metadata is used to describe the basic data specification in general
smart television services, satisfying activities of all stages that the users demand, and
describing service subscription and execution with such basic data, allowing a set of common
definitions and standards to describe simple and complicated services as well as breadth and

4.1.5 General classification of service
4.1.5.1 General description
Classification of a general smart television service is shown in Figure 3. Specifically, a
general service may be classified into basic audio/video playing service and application-based
service. See Annex C for the model for general service context.

– 16 – IEC TR 63122-2:2019 © IEC 2019

Figure 3 – Smart television service classification
Figure 3 gives a general clear description of different smart television services; 4.1.5.2 gives
a more detailed functional description.
4.1.5.2 Basic audio/video playing service
• Live broadcast: similar to ordinary radio and television, it delivers same video/audio
stream to multiple users on the smart television platform provided that the user joins a
certain broadcast channel before using the broadcast service. External television signal
sources include satellite television, cable television, DVB; the content of streaming media
is determined by the broadcast service provider. Programmes offered for live broadcast
may be of standard definition or high definition. The content is continuous without a clear
beginning and ending. Supported by the transmission network, the system can provide
users with a live broadcast service through combined broadcasts to improve the usage
efficiency of bandwidth as much as possible: without support of combined broadcast in the
network, the system may serve the users via a single broadcast.
• Radio: radio mainly includes conventional radio and web radio. The former delivers voice
information via radio waves or wires to allow end user terminals to receive with a receiver
incorporated in smart television. The latter, a web streaming media, establishes a radio
server on Internet sites to disseminate the program through specific software to allow end
user terminals to install and run the radio-receiving software on smart televisions to
connect to these sites and listen to radio programmes.
• Video on demand: video on demand, a type of point-to-point play, allows a single user to
play video/audio streaming as needed. Video on demand services enable the users to
freely allocate their own time and enjoy the programmes that they want to watch. In
addition, with various classification and search methods, the user may find the
programmes that he/she wants to watch as soon as possible. By access to the terminal for
browsing and searching content in stock, a user may play on-demand appropriate
programmes as per his/her demand and preferences. Following submitting requests via
the smart television terminal, a user may browse various programmes provided by the
operator.
4.1.5.3 Application-based service
With application-based smart television services, an end-user terminal may realize a user
service through installing a specific application program offered in an app store. Such a
