The connection to the TV would be an HDMI cable - not WiFi.
That depends on the type of interface and the services being used. I have both direct HDMI and I have streaming over Wifi for live and on demand broadcasts. Make no mistake about it, all of my TVs have streaming Wifi capabilities and we use them daily.
