Road vehicles — Video communication interface for cameras (VCIC) — Part 4: Implementation of communication requirements
ISO 17215-4:2014 specifies the communication requirements for video camera interfaces. It is concerned mainly with layers 1 through 4 of the ISO/OSI basic reference model. These layers are the physical layer, the link layer, the network layer, and the transport layer. The general terminology defined in ISO 17215-1 is also used in ISO 17215-4:2014.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of

Introduction
Driver assistance systems are more and more common in road vehicles. From the beginning, cameras
were part of this trend. Analogue cameras were used in the beginning, because of lower complexity of
the first systems. With increasing demand for more advanced functionality, digital image processing has
been introduced. So-called one box design cameras (combining a digital image sensor and a processing
unit) appeared in the vehicles.
Currently, the market demands such systems with multiple functions. Even different viewing directions
are in use. It seems to be common sense that 6 up to 12 cameras in a single vehicle will be seen in the
next future. Out of this and the limitation in size, power consumption, etc. it will lead to designs where
the cameras are separated from the processing unit. Therefore, a high performance digital interface
between camera and processing unit is necessary.
This International Standard has been established in order to define the use cases, the communication
protocol, and the physical layer requirements of a video communication interface for cameras, which
covers the needs of driver assistance applications.
The video communication interface for cameras
— incorporates the needs of the whole life cycle of an automotive grade digital camera,
— utilizes existing standards to define a long-term stable state-of-art video communication interface
for cameras usable for operating and diagnosis purpose,
— can be easily adapted to new physical data link layers including wired and wireless connections by
using existing adaption layers, and
— is compatible with AUTOSAR.
This part of ISO 17215 is related to the general information and use case definition. This is a general
overview International Standard which is not related to the OSI model.
To achieve this, it is based on the Open Systems Interconnection (OSI) basic reference model specified in
ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers. When
mapped on this model, the protocol, and physical layer requirements specified by this International
Standard, in accordance with Table 1 are broken into:
— application (layer 7), specified in ISO 17215-3;
— presentation layer (layer 6), specified in ISO 17215-2;
— session layer (layer 5), specified in ISO 17215-2;
— transport protocol (layer 4), specified in ISO 17215-4, ISO 13400-2;
— network layer (layer 3), specified in ISO 17215-4, ISO 13400-2;
— data link layer (layer 2), specified in ISO 17215-4, ISO 13400-3;
— physical layer (layer 1), specified in ISO 17215-4, ISO 13400-3.

ISO 17215-3 covers the application layer implementation of the video communication interface for
cameras; it includes the API.
ISO 17215-2 covers the session and presentation layer implementation of the video communication
interface for cameras.
ISO 17215-4 is the common International Standard for the OSI layers 1 to 4 for the video communication
interface for cameras. It complements ISO 13400-2 and ISO 13400-3 and adds the requirement for video
transmission over Ethernet.
ISO 17215-2 and ISO 17215-3 (OSI layer 5 to 7) services have been defined to be independent of the
ISO 17215-4 (OSI layer 1 to 4) implementation. Therefore, ISO 17215-4 could be replaced by other future
communication standards.
