“…On the other hand, subdividing all tiles into smaller granularity would increase the encoding pressure. Consequently, recent research explores dynamic adjustments to tile size [184][185][186] or methods that involve unevenly sized tile partition [187][188][189].…”

“…They achieved this by deemphasizing imperceptible video regions, ensuring efficient 360 • interactive transmission across various network conditions. Gao et al [186] concentrated on selecting optimal encoding parameters, such as tile sizes and quantization steps, to strike a balance between transmission and encoding efficiency. Their objective was to minimize the video distortion displayed in the user's viewport within a given transmission capacity.…”

As assisted driving technology advances and vehicle entertainment systems rapidly develop, future vehicles will become mobile cinemas, where passengers can use various multimedia applications in the car. In recent years, the progress in multimedia technology has given rise to immersive video experiences. In addition to conventional 2D videos, 360° videos are gaining popularity, and volumetric videos, which can offer users a better immersive experience, have been discussed. However, these applications place high demands on network capabilities, leading to a dependence on next-generation wireless communication technology to address network bottlenecks. Therefore, this study provides an exhaustive overview of the latest advancements in video streaming over vehicular networks. First, we introduce related work and background knowledge, and provide an overview of recent developments in vehicular networking and video types. Next, we detail various video processing technologies, including the latest released standards. Detailed explanations are provided for network strategies and wireless communication technologies that can optimize video transmission in vehicular networks, paying special attention to the relevant literature regarding the current development of 6G technology that is applied to vehicle communication. Finally, we proposed future research directions and challenges. Building upon the technologies introduced in this paper and considering diverse applications, we suggest a suitable vehicular network architecture for next-generation video transmission.
