What does Skyworth b20 series direct supply hotel mean?

Skyworth 8h23z-b20, which supports this hotel mode, needs someone to set it up before it can be changed to that hotel mode.

Hotel mode is a locking function. After locking, you can't tune the channel, some volumes can't be turned up, and some analog signals can't be adjusted-fixed at the locked value! After the hotel mode is started, the computer under the router can surf the Internet by setting any IP address, and it can be set in a network segment different from the LAN port. (The IP, mask, gateway and DNS of the computer are allowed to set any address, but they must all be set. ) After the hotel mode is turned on, the IP address of the local connection will be abandoned and the virtual IP address will be used.
