However, with billions of dollars having already been invested by broadcasters, manufacturers, and consumers on currently available HDTV technology, any widespread implementation of 8K resolution TVs and Super Hi-Vision TV broadcasting is still almost a decade away (about the year 2020) as current broadcasting and video format infrastructure cannot handle the extended bandwidth requirements - unless new breakthroughs in compression technology would be able to address this.
8K is not only a ways off, but 4K is just know beginning to make inroads. Also, while 8K resolution may be applicable for very large screen applications, 8K resolution on smaller screen sizes would be overkill - and then there is issue of finding or producing 8K resolution content, and, finally the cost for both broadcasters and consumers for not only the TV upgrade, but other components.
On the other hand, where 8K resolution is seeing use now is in film restoration and mastering, where some movie studios, are taking select classic films and preserving them as 8K resolution digital files to be used in Blu-ray disc and other high-definition mastering applications. Even though current high definition formats are 1080p, mastering from an 8K master insures the best quality transfer available. Also, mastering a 8K means that films or other content would not have to be remastered every time a new high definition format comes into use for either theatrical or consumer applications.
