4K programming, alongside its even pixel dense brother, Ultra HD, do offer an increase in pixel count regardless of the direction, ending up in four times the resolution of 1080p video. This would offer a sharper picture for sure, one that will be extremely easy on the eyes, although with this increase in detail would require an accompaniment in an equivalent, if not more, increase in bandwidth. I suppose one can brand the limited amount of bandwidth to be public enemy no. 1 when it comes to limiting the rollout of 4K content.
Both YouTube and Netflix do offer a certain degree of 4K video, while there are also other manufacturers such as Sony and Samsung who do sell 4K movies, but in these cases mentioned, the video will be delivered via stream or DRM-protected digital file. DirecTV would offer 4K content albeit in an on-demand service, and prices would start from $3.99, going all the way to $15.99 per title. DirecTV has also partnered with South Korean conglomerate Samsung to get the job done, which means these movies and shows will only be able to play on any of Samsung’s 2014 “DirecTV-ready” Ultra HD TVs.
