I dont know if this could help any of you but it is certainly on my xmas list this year! A sling box is used to "sling" all information on tv to smart phone...
For Example: I have direct tv at home and sometimes visit my mom in PA. Usually i am in the car on a sunday and if the NY Giants are on at 1:00 then you can find me speeding to get home. Instead, the sling box acts as a intermediary between internet and television. The box transfers all television data to a server in which you log into and access from your phone. You wont find me speeding any more. Forget purchasing the nfl app...this is the answer. Will also "sling" info on computer if needed. Download movies and stream them to your phone...
