My understanding is it will work through an app designed for varies different devices. Roku, xbox one, pc, mac, ect. Dish wont actually have a box of their own, there is really no need for this service.
You would simply need to have a device capable of downloading the app at each tv to watch (and have a subscription). Of course at this time, you will be limited to one active stream per account. To watch in your bedroom while the wife watches in den, you would need two separate accounts.
50 % of TV viewing to be by app. No equipment to buy/rent, no service people, no install, etc. etc. going to be nice and cheap. Go Sling TV. I am assuming that there will be an app developed to aggregate all these new streaming services into one nice channel menu on our mobile devices or will just 20 choice channels be so good with the new Advertiser supported model that we won't think we need 180 channels anymore? Those new commercials are going to be killer! Some are predicting people will watch TV just to see the new format of commercials. Superbowl Ads will be lame in comparison!
