Vehicular multimedia communications, systems, networks, and applications
|
| Description:
|
1 Motivation
Vehicle data collected by in-vehicle sensors and other electronic devices through in-vehicle networks are critical to intelligent transportation system (ITS) services and applications. They will also enable emergency telecommunications and new business models from associated industries (e.g., insurance, car-sharing).
Vehicle gateways are intended to provide and support telecommunication. In this context, vehicle gateways have a significant role in supporting ubiquitous connectivity in heterogeneous environments. Therefore, global standards for vehicle gateways should also be developed to support global seamless ITS services and applications, and to allow plug-and-play operation in any vehicle for any consumer device.
With the rapid development of intelligent and connected vehicles and automated driving systems (ADS), the future of information and entertainment (infotainment) in the vehicle will drastically change with respect to the traditional infotainment (radio-based), which characterized the vehicles of our generation. While research is progressing towards a vision that supports a vehicle becoming a third living space (after home and office), and its embedded screen becoming the fourth way to accessing infotainment (after TV, PC monitor and mobile phone devices), the need to study vehicular multimedia systems and technologies rises. Study Group 16 established a Focus Group on Vehicular Multimedia (FG-VM) that operated 2018-2022 and pioneered research in the area of vehicular multimedia. This Question continues international standardization in this field.
In addition, given the importance and urgency to preserve our environment from climate change and enhance road safety, ITU-T SG21 recognizes the role of ITS services and applications, which have the potential to improve traffic management, reduce congestion and related carbon emissions, as well as reduce vehicle accidents improving road safety. To this end, ITU-T SG16 established the Focus Group on Artificial Intelligence for Autonomous and Assisted Driving (FG-AI4AD) that operated from 2019 to 2022. This Question continues in ITU-T SG21 to study the deliverables of FG-AI4AD for international standardization. With the recent introduction of automated and assisted driving, the Question will study communications, system, networks, and applications for automated and assisted driving.
As new forms of transportation develop, the Question will study communications, systems, networks, and applications on vehicles in any form, including civilian unmanned aerial vehicles (CUAV).
The Question will defer the study of relevant QoS and QoE aspects of vehicular multimedia systems to ITU-T SG12. The Question will consult ITU-T SG17 when discussing security aspects of vehicular multimedia systems and ITU-T SG20 when discussing smart city aspects of vehicular multimedia systems.
2 Study items
