INTRODUCTION
It is noted that the markets and industries on infotainment services for vehicles (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 navigations, cameras, speakers, headrest
displays, air-conditioners, thermometers and heated seats, and lights.
A set of standards have so far been developed 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 bus or train.
PVIS services have different requirements and features from CCIS services. For user type,
CCIS is targeted for one or two users (such as car owner), whereas PVIS are 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 PVIS can 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 for standardization on PVIS. In particular,
PVIS will 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 bus, train, or subway. It is not applicable to public vehicles, such as airplane
or ship. For this purpose, the following issues are addressed: 1) identify a variety of functional
requirements for provisioning of PVIS, 2) design 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 consists of the following parts:
– Part 1: General
– Part 2: Requirements
– Part 3: Framework
IEC TR 63479-1 describes general considerations and system model for PVIS, with some
examples of PVIS services.
IEC 63479-2 describes the functional requirements for PVIS.
IEC 63479-3 describes the framework, including the functional information flows between
functional entities.

4 Overview
PVIS consist of a diverse ecosystem of entities, each contributing to the system's operation and
functionality. These entities can be categorized into two main groups:
– PVIS support entities: these entities are responsible for supporting the core functions
required by the PVIS. They include the PVIS master, PVIS agent, and PVIS devices. The
PVIS master serves as the central command, controlling and coordinating activities within
the system. The PVIS agent facilitates the connection between the master and the devices,
while the PVIS devices deliver the actual infotainment content to the passengers.
– PVIS user entities: these entities engage with the PVIS system on a more transient basis.
They include passenger devices, content providers, and external applications. Passenger
devices enable users to interact with the system, content providers supply the infotainment
materials, and external applications offer additional functionalities to enhance the overall
user experience.
The PVIS framework defines the functions that the PVIS master, agent, and devices shall
support in order to manage infotainment services effectively and deliver them to passengers
seamlessly.
Figure 1 illustrates how each entity has a specific set of PVIS functions to ensure the smooth
operation of PVIS. It is noted in the figure that the PVIS master should be able to perform the
functions of the PVIS agent, and the PVIS agent includes the functions of the PVIS device.

Figure 1 – PVIS entities and functions
Figure 2 presents a reference architecture of the PVIS system, which includes the six core
functions and the three interworking functions. The core functions are specifically designed to
meet the functional requirements of each entity, while the interworking functions enable smooth
interaction between these entities. The details of these functions are described in Clause 5,
Clause 6 and Clause 7.
Figure 2 – Overview of reference function model
5 Reference model for core functions
5.1 General
The PVIS reference model for core functions comprises several functional modules that
facilitate efficient management and utilization of infotainment services. As illustrated in Figure 3,
PVIS encompass the following modules: authentication management, profile management,
device management, content management, connectivity management, and history management.
IEC 63479-3:2026 © IEC 2026
Figure 3 – PVIS reference model for core functions
5.2 Authentication management function
The authentication management function within PVIS is responsible for delivering customized
services to authenticated users by leveraging their registered information. This function consists
of two crucial subfunctions: certification and permission.
The certification subfunction ensures the identification of each entity within the system and
generates access tokens that grant specific privileges for a limited duration. These access
tokens shall be included in all exchanged messages by the entity, enabling secure and
authorized communication.
The permission subfunction is responsible for validating exchanged messages and governing
the permissions associated with devices and content. Different entities within the PVIS service
can have varying levels of permission to operate devices and access content. The validation
process relies on the access tokens issued by the certification module, ensuring that only
authorized entities can perform permitted actions.
5.3 Connectivity management function
In PVIS, the connectivity information associated with the various PVIS entities plays a crucial
role in delivering efficient and secure services. This connectivity information is represented by
connection and session data.
Within a PVIS system, all functional entities, except for the PVIS master, are required to register
either with the PVIS master or the PVIS agent. During this registration process, a session token
is assigned to each entity. This session token is then included in all subsequent communications,
enabling the PVIS to maintain session context and track entity activities. For instance, a session
for a PVIS device includes details about the device's current state and occupant. Similarly, a
session related to a passenger's device encapsulates information such as the specific PVIS
device being used and the content currently being accessed. This session information forms
the foundation for maintaining effective and personalized interactions within the PVIS.
Furthermore, it facilitates the verification of entity permissions, ensuring secure and authorized
interactions within the system.
IEC 63479-3:2026 © IEC 2026
A connection is established between two entities to facilitate the exchange of messages.
5.4 History management function
The history management function is an essential component of the PVIS framework,
responsible for recording, maintaining, and utilizing historical data related to the usage of
infotainment services. It plays a critical role in improving service quality, enabling personalized
experiences, and supporting decision-making processes.
The module for service usage analytics focuses on acquiring and managing key usage
information, such as the most frequently accessed types of services by users. This data serves
as a foundation for enhancing user convenience and enables functions like content
recommendation and service personalization. Additionally, this information can be shared with
content providers to improve their services.
Furthermore, the history management function oversees the management of system historical
log information. Log information is vital in diagnosing and resolving system errors within the
PVIS. By providing a comprehensive record of system activities and events, it facilitates timely
identification, analysis, and resolution of any issues, contributing to the stability and reliability
of the system.
5.5 Profile management function
Profile management function serves as a repository for storing and organizing pertinent details
associated with devices, agents, and content. These profiles encompass a range of information,
including device specifications, connectivity attributes, access permissions, preferences, and
historical usage data. By collecting and managing such information, PVIS can effectively adapt
its services to meet the specific needs and preferences of individual entities.
5.6 Device management function
In PVIS, device management involves registering devices with a PVIS master or PVIS agent.
The device management function comprises three subfunctions: provisioning, monitoring, and
control.
– Provisioning: the provisioning subfunction handles the configuration process when
registering a PVIS device. This includes assigning a unique identifier to the device, setting
up its network connections, and installing any necessary software. It also covers updating
or decommissioning devices as required.
– Monitoring: PVIS entities registered in the system should always have their latest status
accessible. This is achieved through the following operating procedures:
• Periodic status reporting: PVIS devices periodically send their status to the relevant
PVIS agent or PVIS master. This ensures continuous and controllable connection
between the entities through message exchange. By consistently reporting status, the
PVIS system maintains an up-to-date understanding of the device's status and its
surrounding environment, allowing for identification and pre-emption of potential issues.
• Status reporting on status change: when a status change is detected, the PVIS system
quickly prepares for unexpected situations.
• Querying status: The PVIS master or PVIS agent managing a PVIS device can request
the device's status at any time by sending a status report request. This is useful when a
passenger device requests the list of available devices or when an expected status
report is not received within a specific time threshold.
– Control: the device management function provides a list of available PVIS devices and
