Thank you for posting in the forums! That is a great question! There is not yet an application for the Samsung Smart TV. The Samsung Smart TV has a web browser, however, it will not allow you to install the SlingPlayer plug-in. You could purchase a connected device. An example of one would be a Netgear Neo TV or a Western Digital TV. These are both small devices that will connect to your TV via HDMI and will pretty much turn any HD TV into a smart TV. These devices have the SlingPlayer application built in. All you would have to do is open up the application and connect to your Slingbox and you will be streaming from your TV. Below is a link that tells you all of the supported connected devices.
Hope this helps!
