You need to connect a device that will stream the games (ie computer, smartphone, tablet) to your tv. If you have a computer with hdmi out, you can connect to your hdtv via hdmi. Smartphones would take a wireless device such as chromecast. Whatever you choose, you'll be streaming the games in a browser, there is not a smarttv app for nchc.tv
I don't understand what you think a wireless keyboard might be used for
