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.

In the connection between the last kilometer access network and the backbone network, the dual-hop hybrid freespace optical/radio frequency(FSO/RF) relay system is considered to be an effective solution to increase the capacity and coverage of the wireless communication system. However, the transmission performance of FSO link is greatly affected by atmospheric turbulence, pointing errors and weather such as fog and snow, and the RF access network has low rate and relatively high delay. To ensure communication quality, a hybrid FSO/RFterahertz(THz) relay system has been designed. Decode-andforward relay is selected, and the hybrid FSO/RF communication based on adaptive combining scheme is considered before the relay node, and THz link is used after the relay node to access the users. Using the statistical characteristics of different links obtained, expressions for the outage probability and average bit error rate of the system were derived. The effects of different parameters on the performance of hybrid FSO/RF-THz relay system is studied, and the first hop adaptive combining scheme is compared with the single-threshold switching scheme and the single-link FSO system. The analysis results indicate that the hybrid FSO/RF-THz relay system can provide better outage and bit error rate performance by using the adaptive combining scheme, which can improve the system communication rate while taking into account the communication reliability.

“…Then, the whole traffic travels through either FSO or RF channel; (2) the traffic is duplicated and routed through both the FSO and RF channels simultaneously, and the switcher selects either available traffic at the receiver side. The adaptive combining 2,11 approaches can be viewed as the kind of improved hard‐switching methods avoiding frequent hardware switching between the FSO and RF channels and preferring use of the FSO channel. Some researchers think that hard‐switching methods are not optimal in the sense of exploiting the available resources, they use complicated coding strategies to utilize both channel capacities by encoding data with a portion of the codeword split to FSO and RF links 1,4,6 …”

Hybrid free‐space optical and radio frequency (FSO/RF) systems have attracted much attention for more than a decade because of their enhanced reliability and capacity as comparison to single FSO or RF systems. Existing schemes to construct such a hybrid system are usually to use either switching or encoding/decoding strategies for combination of channels. The proposed scheme, based on packet sharing strategy of Ethernet link aggregation, provides a different way to combine FSO and RF channels. Theoretical analysis and Experimental results show that the proposed scheme does enhance the reliability and utilize both channel capacities for a multi‐channel system. Moreover, this scheme is simple and scalable because more channels can be combined based on such a packet sharing strategy without modifying the physical channel structures, therefore, this scheme may provide a good solution for constructing an efficient and cost‐effective hybrid FSO/RF system.
