There were obvious differences between the transmission signal characteristics, cable structure, and application scenarios of the radio frequency line and the high-definition video signal line. The radio frequency line was mainly used to transmit radio frequency signals. It had a high frequency and a short wave-length, and was suitable for wireless communication, radio and television, radar detection, and other fields. The high-definition video signal line was mainly used to transmit high-definition video signals. It had a lower frequency and a longer wave-length, suitable for cable TV, cameras, and other equipment. The radio frequency line usually adopted a coax structure, which was composed of an inner conductor, an insulation layer, an outer conductor, and a sheath. The inner conductor and the outer conductor were made of highly conducting metal materials to improve the transmission efficiency of the signal. The high-definition video signal line may adopt a variety of structures, such as coax, twisted pair, etc. The material may also vary according to the application requirements, including copper, optical fiber, etc. In addition, the radio frequency cables used BNAC or F-type connections, while high-definition video signal cables such as Bluetooth and DisplayPort had dedicated digital ports to ensure efficient data transmission. In short, there were obvious differences in function, usage, and transmission principle between the radio frequency cable and the high-definition video signal cable.
