While Ultra High Definition (UHD) video is in its relatively early stages insofar as content availability, the price of UHD televisions has dropped much faster than many anticipated, so perhaps there will be an accelerated push to get more content to support it.
One thing you will probably see very little of is streaming. Considering the explosion of streaming in the last few years, with many cutting the cord with their cable TV, it is good to consider the impact on Internet connectivity, especially for the home user.
Currently, an HD movie consumes 25-40GB on a Blu-ray disc, which is a ton. With UHD a movie will be 100-160GB! Think about streaming that! Not only do you have to pull a huge amount of data, you must pull it at a much faster rate to avoid buffering. With many large providers having monthly caps that currently most subscribers don’t reach, you may find that two or three movies puts you in the penalty box, whether throttling, extra charges, or hitting a hard stop. Also consider that many of your neighbors are doing the same thing. How is your provider going to handle that?
What you may well see is the return of the DVD rental market. Right now that has been pretty much killed off, save for RedBox. As more content comes to market, the UHD DVD players are offered for a reasonable price, it will be interesting to see how this need is filled. I don’t see the re-emergence of the retail rental store of old. Time will tell.
