Thank you for using the forums! That's a great question! We do not yet have any SlingPlayer application for any Smart TV. However, you can use something called a Connected Device. An example of one would be a Western Digital TV. It is a small device that connected to your TV via HDMI and has the SlingPlayer application built-in so you can stream right from your TV. It is a streaming player, so it also has Netflix, Youtube, etc..
If you click on the link below it will take you to a page on our website that explains Connected Devices.
Hope this helps!
