If your smart tv is at home connected to your home wifi network then you are good to go. If it is in your RV you are going to need to set up a network. Basically, the smart tv streams media and data sent by wifi from a computer on the network, a smartphone on the network, or a tablet on the network. All of these devices need to be dlna capable and there are many apps - often ones included with the device that will make the connection. Here is an explanation of DLNA (which is actually an organization and standard set up to do all of this)

Anyone without a Smart TV can do the same thing with a Roku box or a BluRay DVD wifi or network wired player connected to a regular TV.
