What’s the Best Way to Distribute 4K?

I don’t think 4K UHD is just another frivolous trend or marketing gimmick to make us spend our hard-earned dollars, only to turn obsolete before the year’s end (3D anyone?). I truly see 4K UHD as a natural transition, or evolutionary step, in screen resolution. In 2015 I expect to see many new models of 4K UHD TV sets than that of 1080p HDTVs.

This doesn’t mean everything is safe and sound and all the potential issues are ironed out. For example, a recurrent question I get at all my presentations is “What’s the best way to distribute 4K?” and the answer is far from perfect, as we now have very limited options.

Let’s take Blu-Ray, for example. A Blu-Ray disc can fit 25 GB per layer. A 2K film takes 50 GB, so that technology is currently maxed out. The good news is that as of last September, the Blu-Ray Association announced it would support 4K video at 60 fps, High Efficiency Video Coding (HEVC), and 10-bit color depth. According to them, the new generation of 4K Blu-Ray disks will have a data rate of at least 50 Mbit/s and may include support for 66/100 GB discs. Awesome!

The huge appeal of HEVC (High Efficiency Video Coding) is that it essentially doubles the data compression ratio while keeping the same level of video quality and it can support 8K UHD with resolutions up to 8192×4320. I want to think that 8K is extremely far off in the future, and that it will be a very long time before we need such resolutions. But, I (sadly) still remember when a 100MB zip drive seemed impossibly huge and we debated if putting all your assets on a 1GB Microdrive was practical or even irresponsible.

As we all know, both the iPhone 6, and iPhone 6 Plus support HEVC/H.265 for FaceTime. Recently, Microsoft confirmed that Windows 10 will support HEVC out of the box, and DivX developers announced that DivX265 version 1.4.21 has added support for the Main 10 profile of HEVC and the Rec. 2020 color space.

Now, going back to my original question: What’s the best way to distribute 4K? Online streaming might also seem like a great solution, but not yet. Netflix recommends a minimum download speed of 5MB for 720p, 7MB for a 1080p and 12MB for 3D movies and a whooping 25MB for 4K.

What’s wrong with this picture? I have a dedicated “business” internet plan. The fastest, and obviously most expensive plan I can get in my area. As you can see below, my download speed is less than 17 MBps, not nearly enough for Ultra HD quality, so broadband speeds will need to increase and prices will have to come down if the interested parties really want 4K widely accepted by movie buffs, sports fans, and hardcore gamers.

A nice advantage of 4K UHD TV sets is that they are retro-compatible, which means that they will work fine with your existing DVD and Blu-Ray players, as well as satellite and cable boxes. They can also “upscale” HD content and display it as best possible. This past summer some of the FIFA World Cup games were broadcast in 4K. I watched a couple and it was a surreal experience. From certain angles, like shots from the sidelines, it felt almost like physically being in the stadium. The most popular VOD providers like Netflix and Amazon, major cable companies like Comcast and DirectTV, Hollywood studios, YouTube, and even local TV news station are starting to deliver 4K content. Hopefully other services like Vimeo will follow suit.

So, what’s next? Streaming 4K media from a smartphone to an HDTV?

  1. Speaking from personal experience working around these products every day, I would suggest looking at a Hisense like the H8C. They tend to come in well under your budget, even in a 55″. I would say not to put a Samsung in the 6000 or 7000 series on the top your list, because you just don’t get as many features for better viewing quality in those. If for some reason you can find it on a sale in your price range or near to it, my recommendation would be an LG 7700, as it tends to be the happy medium between brand, build quality, picture quality, features, and cost. However, the LG is normally anywhere from about $800-$1,000 US for a 50″.
