INTRODUCTION
This document specifies recording methods of the drive monitoring surround view system
specified in IEC TS 63033-1, which also specifies the model for generating the surrounding
visual image of the drive monitoring surround view system. The system allows drivers to monitor
the car vehicle's perimeter in real time by using "free eye point" technology, which allows drivers
to dynamically change the viewing perspective, offering the most appropriate views according
to the driving situation.
IEC 63033-2 specifies recording methods of the drive monitoring system in order to view the
recorded video file with "free eye point" technology.

4.1 General
IEC 63033-2 specifies recording methods of the drive monitoring system. Specifically, the
recording from a vehicle-mounted camera as obtained by the drive monitoring system, and also
a model for the replay of the recorded video. The purpose of the replay of the recorded video
can be considered in various ways, such as verification at the occurrence of an accident, as
legal proof, for reviewing driving behaviour and use at educational sites.
This document specifies the recording methods of footage obtained from a vehicle-mounted
camera that is part of the surround view system, and also specifies a model for the replay of
the recorded video. The replay of the recorded video can serve a number of purposes, such as
the verification of the reasons of an accident, as legal proof, for reviewing driving behaviour,
and use at educational sites.
There are two types of recorded videos: recording of each camera image (referred to as
"recording 1"), and recording of the composite image (referred to as "recording 2"). For replay
of use when the recorded videos are played back, the related metadata (refer to 4.2.2.3 and
4.2.3.3) is simultaneously saved in recording 1 and recording 2. These recorded files are
transferred by a portable recording medium or via a network, where they can be later replayed
played back by the user. The user can also recreate the composite image by using the stored
metadata in by using the free eye point function in the viewer (refer to Clause 5). It is also
possible to provide the distribution service with the recorded file by using storage on the network.

system
4.2 Video recording
4.2.1 General
There are two types of recording files provided by the driver monitor system and as shown
Figure 1: recording 1 and recording 2.
4.2.2 Recording 1
4.2.2.1 General
Recording 1 consists of both the raw video data (before the composite image is created) as
obtained by each camera, and the related metadata (refer to 4.2.2.3 at the same time). Using
both the video data and the metadata enables the user to recreate a new composite image. The
user can change the viewpoint freely while viewing the composite image. In addition, they can
also see a vehicle's surroundings instantly in a single composite image.
4.2.2.2 Video data
The raw video data obtained from the vehicle-mounted cameras is recorded. The raw video
data example is described in Figure 2.
Since the recording is pre-composition, there is no distortion, and the image cut-off is as directly
input from each vehicle-mounted camera. This method allows for the full image to be transferred,
thus keeping as much most of the original image information.

4.2.2.3 Metadata for recording 1
The metadata listed in Table 1 and Table 2 shall be saved together with the video data. Some
metadata will be included in the SIM source packet.

4.2.3 Recording 2
4.2.3.1 General
Recording 2 records both the composite image video data and the related metadata (refer to
4.2.3.3) at the same time. The composite image video data example is described in Figure 3.
Users cannot change the viewpoint while viewing the composite image. However, the user can
instantly view the vehicle's surroundings through a specific pre-set composite image regardless
of the viewer used (see Clause 5 for details).
Figure 2 – The composite video data example of recording 2
4.2.3.2 Video data
The composite video data obtained from vehicle-mounted cameras is recorded.
Compared to the case of recording the raw video data of captured by all the cameras, it can
reduce the data size and memory required since only the composite result is recorded. On the
other hand, the image information from each camera that has not been used in the composite
image will be lost.
4.2.3.3 Metadata for recording 2
The metadata listed in Table 3 Table 1 shall be saved together with the video data. Some
metadata will be included in the SIM source packet.

5.1 General
Figure 3 – Viewer example
The term "viewer" designates the video player necessary to view the recorded file and can be
classified into two types, as shown in Figure 4. These are further referred to as the "general
viewer" and "enhanced viewer" depending on whether or not the viewer has a free viewpoint
function.
5.2 General viewer
The general viewer plays the recorded video data just as it is, and sometimes crop and zoom
functions are enabled. The metadata regarding the timestamp, GNSS and orientation shall be
synchronous with the video data and displayed in the viewer.
5.3 Enhanced viewer
In addition to the general viewer's basic function, the enhanced viewer enables users to view
the video data with the free viewpoint function. In order to generate a composite image with
"free eye point" free viewpoint, the video data and the metadata recorded in recording 1 is
necessary.

Part 2: Recording methods of the surround view system
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.

INTRODUCTION
This document specifies recording methods of the surround view system specified in
IEC 63033-1, which also specifies the model for generating the surrounding visual image of the
surround view system. The system allows drivers to monitor the vehicle's perimeter in real time
by using "free eye point" technology, which allows drivers to dynamically change the viewing
perspective, offering the most appropriate views according to the driving situation.

4 System model
4.1 General
This document specifies the recording methods of footage obtained from a vehicle-mounted
camera that is part of the surround view system, and also specifies a model for the replay of
the recorded video. The replay of the recorded video can serve a number of purposes, such as
the verification of the reasons of an accident, as legal proof, for reviewing driving behaviour,
and use at educational sites.
There are two types of recorded videos: recording of each camera image (referred to as
"recording 1"), and recording of the composite image (referred to as "recording 2"). For use
when the recorded videos are played back, the related metadata (refer to 4.2.2.3 and 4.2.3.3)
is simultaneously saved in recording 1 and recording 2. These recorded files are transferred by
a portable recording medium or via a network, where they can be later played back by the user.
The user can also recreate the composite image by using the stored metadata by using the free
eye point function in the viewer (refer to Clause 5).

4.2 Video recording
4.2.1 General
There are two types of recording files provided by the driver monitor system and as shown
Figure 1: recording 1 and recording 2.
4.2.2 Recording 1
4.2.2.1 General
Recording 1 consists of both the raw video data (before the composite image is created) as
obtained by each camera, and the related metadata (refer to 4.2.2.3). Using both the video data
and the metadata enables the user to create a new composite image. The user can change the
viewpoint freely while viewing the composite image. In addition, they can also see a vehicle's
surroundings instantly in a single composite image.
4.2.2.2 Video data
The raw video data obtained from the vehicle-mounted cameras is recorded. The raw video
data example is described in Figure 2.
Since the recording is pre-composition, there is no distortion, and the image cut-off is as directly
input from each vehicle-mounted camera. This method allows for the full image to be transferred,
thus keeping most of the original image information.

4.2.2.3 Metadata for recording 1
The metadata listed in Table 1 and Table 2 shall be saved together with the video data. Some
metadata will be included in the SIM source packet.

Metadata Explanation Mandatory
It is necessary to identify the exact time when a certain event
occurred. The time information is generally extracted from
Timestamp GNSS. If GNSS is not included in the system, the time ✔
information can be extracted from another system equivalent
to GNSS.
It is necessary to identify details about the location and the

4.2.3 Recording 2
4.2.3.1 General
Recording 2 records both the composite image video data and the related metadata (refer to
4.2.3.3) at the same time. The composite image video data example is described in Figure 3.
Users cannot change the viewpoint while viewing the composite image. However, the user can
instantly view the vehicle's surroundings through a specific pre-set composite image regardless
of the viewer used (see Clause 5 for details).

4.2.3.2 Video data
The composite video data obtained from vehicle-mounted cameras is recorded.
Compared to the case of recording the raw video data captured by all the cameras, it can reduce
the data size and memory required since only the composite result is recorded. On the other
hand, the image information from each camera that has not been used in the composite image
