Specifically, because the flow required by the 8K signal is very large, the same data can be transmitted for many times by directly sending the data point to point, and thus great pressure is caused to the system. In this embodiment, the route configuration module 42 is configured to configure the IP network so that the backup conversion device converts the IP signal from the specified camera.

Compared with the first scheme and the second scheme, the third scheme (referred to as the third scheme) in the fourth embodiment may output a video through the backup conversion device, but the video is only a video and cannot be subtitled, so the third scheme is generally used as a final means.
