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.

INTRODUCTION
It is noted that the markets and industries on infotainment services for vehicles (as known as
in-vehicle infotainment services) have been growing rapidly. It is envisioned that a variety of
infotainment (or multimedia) devices and services will be newly developed for personal and
public vehicles in the future. Such devices include navigation systems, cameras, speakers,
headrest displays, air-conditioners, thermometers and heated seats, and lights.
IEC TC100 have so far developed a set of standards on Configurable Car Infotainment Services
(CCIS) with the IEC 63246 series. However, the CCIS standards have been basically designed
for personal users, such as car owners. In the meantime, there is also a crucial need to provide
a variety of infotainment services for public vehicles (PVIS), such as buses or trains.
PVISs have different requirements and features from CCISs. For user type, CCIS is targeted
for one or two users (such as car owner), whereas PVIS is for a large number of guests or
passengers within the public vehicle. For device type, CCIS deals with the personal devices
(property or belonging) in the car, whereas PVIS will be targeted for a variety of public devices
that are contained in a public vehicle. Some PVIS services can be provisioned by interworking
with the external networks, as shown in the bus information service. For service duration, CCIS
usually provide long-term services, whereas PVISs are intended to provide short-term service
during which a guest stays within a public vehicle.
From these observations, it is noted that there are many different features and requirements
between CCIS and PVIS. Accordingly, there is a need of standardization on PVISs. In particular,
PVISs needs to employ a set of agents to effectively manage a large number of users or devices.
The PVIS series (IEC 63479) describes infotainment (multimedia) services for terrestrial public
vehicles, such as buses, trains, or underground railways. It is not applicable to public vehicles,
such as aeroplanes or ships. For this purpose, the following issues are addressed:
1) identification of a variety of functional requirements for provisioning of PVISs;
2) designing of the PVIS framework, based on the identified requirements.
The PVIS standards are expected to provide guidelines on PVIS services for a large number of
users/devices, and to encourage development of new (enhanced) PVIS services (possibly by
interworking with the external systems).
The IEC 63479 series consists of the following parts:
– Part 1: General,
– Part 2: Requirements, and
– Part 3: Framework.
IEC 63479-1 (this document, Technical Report) describes general considerations and system
model for PVIS, with some examples of PVIS services.
IEC 63479-2 (International Standard) describes the functional requirements for PVISs.
IEC 63479-3 (International Standard) describes the framework, including the functional
information flows between functional entities.

Service duration (Usually) long-term (Usually) short-term
Security/privacy Moderate Crucial

Public vehicles for PVIS (e.g. bus, train) have different requirements and features from private
vehicles (e.g. car, van). A private vehicle is usually for a small number of users, whereas a
public vehicle is targeted for a large number of guests or passengers. For device type, a private
vehicle deals with the personal devices (property or belonging), whereas a public vehicle is
targeted for a variety of public devices that can be shared by many users in the public vehicle.
Some public services can be provisioned by interworking with the external networks, as shown
in bus information service. For service duration, the private vehicle usually provides long-term
services, whereas the public vehicle tends to provide short-term services during which guests
stay within the public vehicle. Security or privacy requirements are also strictly applied to the
public vehicle, compared to the private vehicle.

– 8 – IEC TR 63479-1:2023 © IEC 2023
As shown in Annex A of this document, most of the existing relevant standards have focused
on the personal vehicle. The multimedia services for public vehicles have not been addressed
so far. In particular, this document describes the system model to be considered to effectively
provide the PVIS services, which includes the target environment and functional entities. Some
examples of PVISs are also described.
5 System model
5.1 Functional entities
5.1.1 General
PVIS functional entities are classified into the five types: content provider, PVIS master, PVIS
agent, PVIS device, and passenger device.
5.1.2 Content provider
The content provider represents an external server or entity to provide multimedia infotainment
services for PVIS passengers, such as multimedia on-line game or over-the-top (OTT) services.
Content providers may deploy their contents as PVIS services with an appropriate negotiation.
Such contents include a variety of applications, such as games, utility programs, or media files
for OTT services. For this purpose, a content provider may give an interworking function with
the PVIS system for enhanced PVIS service provisioning.
5.1.3 PVIS master
The PVIS master performs overall management and control for PVIS system and services. In
initialization, the PVIS master needs to identify a set of PVIS functional entities within the public
vehicle, such as PVIS agents, PVIS devices and passenger devices. For service duration, the
PVIS master monitors these PVIS functional entities. The PVIS master is also responsible for
content delivery from the content provider to many passengers in the public vehicle.
5.1.4 PVIS agent
The PVIS agent is additionally employed for large-scale public vehicles, such as trains, to
provide scalable and effective PVIS services between the PVIS master and a large number of
passengers. It is expected that a PVIS agent is employed for each carriage in a large-scale
public vehicle. The PVIS agent is responsible for the management of PVIS devices in its
carriage. The PVIS agent is also responsible for service provisioning to PVIS passengers who
are in its carriage. For this purpose, the PVIS agent may temporally store multimedia contents
for passengers during communication between the PVIS master and passengers.
5.1.5 PVIS device
The PVIS device represents a device that is attached and dedicated to the public vehicle, such
as air conditioning, speakers, displays, lights, and sensors. The PVIS devices are used for a
variety of PVIS services. Each PVIS device needs to be controlled and managed by a PVIS
master or agent. PVIS devices support the interaction of users with the PVIS agent or PVIS
master.
5.1.6 Passenger device
A passenger device is a user device for PVIS services, such as a smartphone, for which
passengers use PVIS services via the passenger device. By using such a passenger device, a
passenger can request PVIS services to the PVIS device, PVIS agent, and further to the PVIS
master. How to implement the passenger device is outside the scope of this document.

5.2 Network environment
5.2.1 General
For description of PVIS services, the two types of public vehicles are considered: small-scale
public vehicles (e.g. buses), and large-scale public vehicles (e.g. trains).
It is expected that the communications between functional entities within a public vehicle (e. g.
PVIS master, PVIS device, passenger device) are performed by using wireless personal area
network (WPAN) technology, such as Bluetooth or Wi-Fi. In the meantime, the communications
between a content provider outside the public vehicle and the PVIS master within the public
vehicle can be done by using a mobile communication technology, such as 5G or 6G.
5.2.2 Small-scale public vehicles
Figure 1 shows a network model of a small-scale public vehicle environment, such as a bus.
The small-scale public vehicle consists of a PVIS master and a set of PVIS devices and
passenger devices. For PVIS service provisioning, all PVIS devices and passenger devices
need to be registered with the PVIS master. Passengers can control PVIS devices and enjoy
PVIS service through the associated passenger devices.

Figure 1 – Small-scale PVIS environment (e.g. bus)
5.2.3 Large-scale public vehicles
Figure 2 shows a network model of a large-scale public vehicle environment, such as a train.
In this case, a PVIS agent is employed for each carrige in the public vehicle. For PVIS service
provisioning, all PVIS agents, PVIS devices and passenger devices in the vehicle need to be
registered with the PVIS master.
