[0003] At the same time, all kinds of TV OB vans that have been put into use basically do not have the capability of satellite broadcasting. When TV OB vans perform live / broadcast work in the field such as stadiums, large-scale performing arts sites or large-scale conference sites, they often need to be equipped with A special satellite communication vehicle or satellite OB vehicle is responsible for forwarding the program signal output by the TV OB vehicle to the satellite receiving equipment in various places through TV relay satellites
Complicated on-site commissioning work between two vehicles, and dispatching two vehicles will also result in higher costs

The invention provides an 8K ultra-high-definition video full-service rebroadcasting vehicle supporting 5G live broadcast, and the vehicle is characterized in that an 8K switching platform carries out the switching and on-site production of 8K video signals, converts the obtained 8K video program signals into an SDI format, and outputs the converted 8K video program signals to an 8K monitoring system, 5G communication equipment and satellite rebroadcasting equipment; the 8K monitoring system monitors 8K video program signals; the 5G communication equipment encodes the received 8K video program signal and outputs the encoded 8K video program signal; the rebroadcasting vehicle can also encode the received 8K video program signal through the satellite rebroadcasting equipment, and forward the encoded 8K video program signal through the satellite transmitting antenna. The 8K full-service rebroadcasting vehicle with the 5G live broadcasting and satellite rebroadcasting functions is provided, ultra-high-definition video live broadcasting is carried out through the wireless communication network, the number of connecting cables is reduced, manufactured programs are transmitted through the wireless communication network and a satellite transmission link, and the programs can be transmitted to a playing terminal more conveniently.
Description
technical field [0001] The invention relates to the technical field of signal processing, in particular to an 8K ultra-high-definition video full-service OB vehicle supporting 5G live broadcast. Background technique [0002] At present, the overall production technology of 4K and 8K ultra-high-definition video and the development of live broadcast / rebroadcast technology are not perfect. Ultra-high-definition video, especially 8K ultra-high-definition Large-scale transformation does not have the ability to transmit 8k ultra-high-definition video programs. 8K TVs on the application side have begun mass production, and outdoor large-screen display devices capable of playing 8K ultra-high-definition videos have also appeared in large numbers. High-performance 5G mobile phones also support receiving and playing 8K ultra-high-definition videos. A solution for more convenient transmission of 4K ultra-high-definition video to 8K / 4K TVs, 8K / 4K set-top boxes, outdoor large-screen dis...
