## 3 Multimedia
### Applications and Use-Cases  
The integration of multimedia capabilities into vehicular ad hoc networks (VANETs) and DSRCs has presented a multitude of opportunities for enhancing different facets of vehicular communication systems. This convergence of multimedia and vehicular technologies has paved the way for the development of various applications and services that leverage multimedia content to improve safety, public safety, entertainment, telemedicine, and advertising within the driving environment as shown in Figure 3. These advancements signify a significant step forward in the realm of vehicular communication, offering promising opportunities for further exploration and innovation. Safety of life is a critical aspect of multimedia integration in VANETs/DSRC, aiming to mitigate the risk of accidents and enhance overall road safety. One prominent application within this category is collision avoidance, where vehicles share sensor data and cooperate to prevent collisions. This involves real-time multimedia sharing between vehicles to enable effective sensor fusion and accurate situational awareness. Additionally, intersection assistance systems utilize multimedia to facilitate safe and efficient maneuvering at intersections, improving traffic flow and minimizing the risk of accidents. Public safety applications leverage multimedia capabilities to enhance the effectiveness of law enforcement and emergency response operations. Police departments, for instance, can benefit from real-time dashcam video streaming from patrol cars, providing valuable visual information for situational analysis and incident response. Furthermore, multimedia content can be streamed from a central server to vehicles over DSRC, enabling the dissemination of critical information, such as traffic updates, emergency alerts, and public service announcements. Entertainment is another domain that has been enriched by the integration of multimedia in VANETs/DSRC. Passengers and drivers can access a variety of entertainment services through streaming platforms, providing them with access to music, podcasts, audiobooks, and other multimedia content. This enhances the overall in-vehicle experience, making travel more enjoyable and engaging. Figure 3: DSRC architecture stack. Advertising opportunities have also emerged within the context of VANETs/DSRC, enabling targeted multimedia advertising campaigns. Welcome Centers, for instance, can utilize audio streaming capabilities to greet approaching vehicles and provide relevant information about local attractions and services. Video streaming can also be employed to deliver engaging advertisements to passengers and drivers, leveraging the connectivity and multimedia capabilities of VANETs/DSRC to enhance marketing efforts. The integration of multimedia capabilities into vehicular ad hoc networks (VANETs) and DSRC has brought forth a multitude of opportunities for enhancing various aspects of vehicular communication systems. This convergence has led to the development of applications and services that leverage multimedia content to improve safety, public safety, entertainment, and advertising within the driving environment. However, alongside these advancements, researchers face the challenge of addressing bandwidth issues that affect the seamless transmission of multimedia content. In the realm of safety, applications such as collision avoidance and intersection assistance rely on real-time multimedia sharing between vehicles to enable effective sensor fusion and accurate situational awareness. Public safety applications benefit from real-time dashcam video streaming and the dissemination of multimedia content over DSRCs, providing valuable visual information for law enforcement operations and facilitating the delivery of critical information to vehicles. The integration of multimedia has also enriched the entertainment domain within VANETs/DSRC, allowing passengers and drivers to access various streaming services and enhancing the in-vehicle experience.
