As long as you can not switch to 50p that thing, it is in Europe only "game stuff" and no better than if you have a PC (which also rarely 50i / 50p output) to the TV connects (it is only more comfortable)
In particular for a commercial online Videothekten as max cathedrals, etc. of Chromecast is not serious to use as just suffer through the artificial and unnecessary jerking resulting quality in unprofessional manner. If you pay for the movies is absolutely unacceptable!
One may wonder whether even the Americans could have an interest in 50p or if not the whole world could have an interest in that he 24p (or 48p) may issue Chromecast to Films Cinema True and completely without any lag even to enjoy (apart from the standard 24p judder, but can the TV so usually wegglätten or can I watch "The Hobbit 1-3" [AFAIK currently the only 48p-HMR movies] and then HMR 48p)
If not 24p or 48p, then please at least 50p --- there is indeed depends on how the films be offered. I suspect that --- as long as movies --- be there in 24p and are also streamed as well. The jerky then unfortunately when playing with 50p --- although probably slightly less than 60p.
Brave new world of HD: Dolby Digital, Full-HD, Interlace is almost perfectly calculated away, UHD 4K is coming, then the next (would actually have been already due at full HD, but lacking in self-UHD --- is the color space increases, we will see it, appreciate from about 2020 to 2025) ***** ***** BUT adjusting the framerate is neglected more than ever!
One must obviously buy is indeed a high-end TV, the "intelligent" not just doubled the Bidanzahl but can wegkompensieren nasty stuttering and must therefore do things that a few years ago could only professional equipment, for example, Movies run slightly faster or slower to make in order to pack an the allowable Maxmimum on advertising better.
