I use a slibgbox to get the games on my ipad and smartphone.
Expensive to get into, $200 at least...quality depends on a few things like a high quality internet connection where the box is located....the type a of connecrion to the set top box I.e.hdmi v. Component......
For these broadcasts its a meh at best....for quality. But its much better than the pay web feed UND sells.
My older slinbox fried out so i bpught the online und access watched a few weekends and went an bought a new slingbox.
As long as the internet is good and strong slingbox is good for hockey.....it pays for itself in nhl games instead of paying doe game center if u buy centerice.
