Overview

IEC 63033-2:2018 is an international standard published by the International Electrotechnical Commission (IEC) that focuses on recording methods for drive monitoring systems used in car multimedia equipment. This standard is part of the IEC 63033 series which addresses various aspects of automotive multimedia and monitoring technologies. Specifically, IEC 63033-2 defines how video data captured from vehicle-mounted cameras should be recorded and managed to enable advanced viewing capabilities, notably through free eye point technology. This technology allows drivers and users to dynamically change the viewing perspective when reviewing footage, offering customizable and context-appropriate visualizations of the car’s surroundings.

This standard complements IEC TS 63033-1, which defines the general drive monitoring system. IEC 63033-2 covers technical details such as video recording types, metadata handling, and video playback models that support accurate and flexible video review, useful for verifying incidents, legal documentation, driving behavior analysis, and educational purposes.

Key Topics

Recording Methods

The standard describes two primary recording approaches for the drive monitoring system:

• Recording 1 (Raw Video Recording): Captures the raw video data directly from each vehicle-mounted camera before any composite processing. This preserves the complete original image information without distortion or cut-offs, enabling detailed analysis and the ability to recompose the scene dynamically.

• Recording 2 (Composite Video Recording): Captures an already combined video image that merges the views from multiple cameras into a single composite for immediate viewing.

Metadata Integration

Integral to both recording methods is the inclusion of metadata, which enhances video utility by providing contextual data such as time stamps (synchronized via Global Navigation Satellite System, GNSS), camera parameters, and stream information. Metadata supports the reconstruction of composite images for review and ensures accurate temporal alignment critical for forensic or educational use.

Viewer Functionality

IEC 63033-2 also specifies requirements for video viewers, including:

• General Viewer: Basic playback that allows viewing recorded files.
• Enhanced Viewer: Advanced features that allow users to move the viewpoint dynamically within the recorded composite image, leveraging free eye point technology for sophisticated post-event visualization.

Applications

The recording methodologies defined in IEC 63033-2 apply to various practical scenarios in vehicle safety and multimedia systems:

• Accident Verification and Legal Evidence: Secure and standardized video recording aids in accident analysis and supports evidentiary requirements in legal settings.
• Driver Behavior Monitoring: Enables fleet operators and insurers to review driving patterns for coaching and risk assessment.
• Educational Use: Recorded drive footage with flexible viewing enhances driving schools and safety training programs.
• Telematic and Multimedia Integration: Supports advanced in-car systems providing comprehensive spatial awareness through dynamic video perspectives.
• Networked Storage and Distribution: The standard accommodates transferring and storing recordings via portable media or network systems for broader access.

Related Standards

IEC 63033-2:2018 is closely linked to other standards in the automotive multimedia and electrotechnical domain:

• IEC TS 63033-1: Defines the general drive monitoring system and the visual image generation model upon which IEC 63033-2 builds for recording specifics.
• Global Navigation Satellite System (GNSS) standards: Provide protocols for accurate time stamping needed in recording metadata.
• ISO and IEC Electropedia: Refer to these databases for standardized terms and definitions related to multimedia and electrotechnical systems referenced in IEC documents.
• Other IEC Multimedia and Video Standards: Committees such as IEC TC 100 focus on audio, video, and multimedia technologies that support interoperable automotive multimedia standards.

---

IEC 63033-2:2018 establishes a robust framework for recording and reviewing automotive drive monitoring videos with flexibility and precision, enabling enhanced driver safety, situational awareness, and regulatory compliance through advanced multimedia technology standards. Adherence to this standard ensures a common global language and method in the cutting-edge field of automotive multimedia and monitoring systems.

INTRODUCTION
This document specifies recording methods of the drive monitoring system that is specified in
IEC TS 63033-1, which also specifies the model for generating the surrounding visual image
of the drive monitoring system. The system allows drivers to monitor the car’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.
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 the recorded videos, 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 the portable
recording medium or via a network, where they can be later replayed by the user. The user

can also recreate the composite image by using the stored metadata in the free eye point 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.

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 (before composite) video data as obtained by each
camera, and 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 view point 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. A raw video data
example is shown 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 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. A composite image video data example is shown in Figure 3.
Users cannot change the view point 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 3 – 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 all 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 shall be saved together with the video data. Some metadata
will be included in the SIM source packet.
