1. Pull the AV cable to another room, and output the SD signal to the big screen TV or projection.
2. Output to high-definition display equipment or pilot station through HDMI and SDI (the line quality is high, HDMI cannot be longer than 10 meter, and the SDI line with good quality is at most 70 to 80 meters);
3. Live on the Internet through the Internet.
About these three kinds, others are not commonly used.
The first one is the cheapest. Tell the cameraman in advance that he will bring you one if there is a cable. It won't cost much if you don't buy it yourself
In the second case, it doesn't cost much to connect the 10 meter line to the display device with HDMI only! If the cameraman has a cable, it will usually be100,200. However, the security and stability of the 10 meter HDMI cable at the wedding scene is hard to say. There are many people at the scene. Whoever breaks it for you will lose the chain. If the line is broken, it will cost less than two or three hundred dollars. If it is a high-end line, it will cost several thousand dollars. It is safe and stable to use SDI cable, but only if the camera and display terminal support SDI interface. If the pilot station is used, the cost will go up at once. It is possible to say one or two thousand at a time and four or five thousand at a time.
The third kind is more troublesome. There should be equipment for converting signals into network format, and the interface between the camera and the converter should be consistent regardless of whether a guiding station is connected; Then you should communicate with the broadcast website in advance and ask them to reserve an interface for you; It depends on whether the on-site hardware broadband is enough, communicate with the on-site network management, and reserve enough upload bandwidth for you in advance; Every step will fail, and then you have nowhere to cry.
I suggest that you find a professional to arrange these things, you speak out your requirements, and let the professionals arrange and solve other problems.
