Just so I know we're talking about the same thing, I'm talking about the phone app. When I watch the Olympics online @
http://www.nbcolympics.com/ I get the same/similar commercial that you're mentioning. When I watch from the phone app, I only get a commercial when I start the app and then none thereafter. Unlike the online version, they cover every moment of every event that I'm mainly interested in. I like/watch a lot of sports but I follow all of the throws competitions closely. Last night we were watching the women's discus qualifying. Watching any one of the other 10 or so televised channels or the online channels, we'd be lucky to see one or two throws. We watched the entire event from start to finish without interruption. It was about 2 1/2 hours long.
No fluff! No more of those feel good background stories. No Bob Costas. No commentators on many of the broadcasts. Only the sport. Great camera angles. Just the way I like it.
We are using an Amazon Fire Stick with the NBC Sports App that we downloaded at the beginning of the games. I'm sure that other means of streaming internet video are available through similar devices. At other times I use the 'share option' available on my Samsung phone to stream directly to the television. The HD quality over my home network is no different that any of the televised broadcasts.
I know I've mentioned it several times..... 4K is a game changer, probably soon to be 8K. On Dish Network as well as other providers, 4K broadcasts of the Olympics are available. The difference between HD and UHD 4K broadcasts are similar to the transition from analog to digital in quality. The only 4K broadcasts that Dish and some other are providing are on a 24 hour delay due to down-converting the signal from 8K to 4K. Turns out that Japan is currently broadcasting the games in 8K. I don't know what is involved in down-converting that to 4K but apparently there is a process that requires the delay. I have not seen a 8K broadcast in person so I can only imagine how that must look. We are always behind with this type of technology in the US. Japan started broadcasting in 8K 5 days ahead of the Rio Olympics, so we'll probably see it in a year or two. They'll probably wait until a majority of the US upgrades to UHD 4K before releasing the next level of technology.
We've always been huge sports fans. I'm lucky to have a wife that enjoys sports every bit as much as I do. We've watched the Olympics for many, many years. With the help of today's technology, we've enjoyed this edition much more than years ago. Can't wait to see what is in store for the Winter Olympics.
