Vehicular multimedia communications, systems, networks, and applications
(Continuation of Question 27/16)
MotivationVehicle data collected by in-vehicle sensors and other electronic devices through in-vehicle networks are critical to intelligent transportation system (ITS) services and applications, and it will enable new business models from related industries (e.g. insurance, car-sharing, etc.), including emergency telecommunications.
With the rapid development of intelligent and connected vehicles, as well as autonomous driving technologies, 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 foresees 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 arises.
Study Group 16 established a Focus Group on Vehicular Multimedia (FG-VM) in 2018 and it pioneered research in the area of vehicular multimedia. This Question plans to build from the work of FG-VM and embrace 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 SG16 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) in 2019 and this Question will monitor developments by FG-AI4AD in view to analyse their findings and related international standardization needed.
Vehicle gateways are intended to provide and support telecommunication both within the car and outside it (vehicle to vehicle and vehicle to infrastructure). In this context, vehicle gateways have a significant role to support 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.
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.
Study itemsStudy items to be considered include, but are not limited to:
- use cases and requirements of future vehicular multimedia systems based on convergent broadcasting and communication networks (including IMT-2020/5G);
- architecture of a vehicular multimedia system based on convergent networks;
- definition and the scope of a vehicle gateway platform and its interfaces with a vehicular multimedia system;
- implementation aspects of vehicular multimedia systems, APIs and communication protocols;
- functions and service requirements of a vehicle gateway platform to support vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-on-board nomadic devices (V2D), vehicle-to-pedestrians and bicycles (V2P) communications;
- functional architectures and mechanisms of a vehicle gateway;
- use cases and scenarios for vehicle gateways as a bridge between vehicles (V2V) and between vehicles and infrastructure (V2I), between vehicles and on-board nomadic devices (V2D), and between vehicles and pedestrians and bicycles (V2P);
- how ICT can support enhancements required to provide energy savings and reduction of gas emissions;
- enhancements to support, directly or indirectly, emergency and early warning services (e.g. for traffic accidents);
- enhancements required to support security and privacy of vehicular gateways and multimedia systems;
- considerations on road safety with respect to ITS and connected autonomous vehicles (CAV);
- considerations on the integration of ubiquitous devices;
- the Question might only study applications that are specific to the vehicle.
TasksTasks include but are not limited to:
- studies on the use cases and requirements in terms of services/applications and functions to support V2V, V2I, V2D, and V2P;
- studies on the use cases, requirements and functions of vehicle gateway and vehicular multimedia and their reference model(s);
- studies on the open interface between VGP, vehicular multimedia system and networks;
- studies on the open interface between VGP and ICT devices;
- studies on the relevant necessary protocols to support vehicle-oriented services and applications;
- studies on implementation aspects of vehicular multimedia systems, APIs and communication protocols;
- studies on road safety, autonomous and assisted driving and the performance evaluation of the artificial intelligence system responsible for the driving tasks;
- study the deliverables from ITU-T FG-VM and FG-AI4AD to assess their maturity and identify a path towards their endorsement as ITU-T Recommendations;
- maintain deliverables under the responsibility of the Question: ITU-T F.749.1, F.749.2, F.749.3 (ex F.VM-URVMN), H.550, H.560, H-VDS series.
