Android boxes are discussed plenty in the forum, but Sports coverage like F1 is only available legally via Service Providers, where you pay for the service. Or perhaps via paid streaming services.
When I click on your Vetek link it talks about getting Free Satellite and Cable. There is no such thing. Free Satellite and Cable is called theft or piracy and we don't allow discussions of same on this forum. See also the following thread where piracy/theft is discussed in detail:
Edit - I believe only the main events (Practice, Qualifying, Race) are covered in 4k for F1 and then probably only certain cameras, and not the pre/post programming. This would be similar to the early days of HD where there were a few HD cameras at the sporting event but many cameras at that time were still SD. You are not imagining things though as I have also noticed some images of F1 to be superior to previous years, however, this may be due to other factors including superior signals to various "broadcasters" like TSN, etc.
