Get Clear Insight on 4K & it's Worth
4K has been hyped as the next big thing in video, but unless you are an A/V geek, it is all too easy to get confused about what it means. Yoel Zanger, CEO and Founder of Giraffic gives you the insight you need to understand 4K.
-Viewing experience and image reality like never before – it’s almost like looking out your window.
- Up scaling technology available which makes regular HD 1080p content look even better
- A driver of the consumer electronics industry and economy: many new technologies and vendors. (e.g. processors, Codecs, Adaptive Video Acceleration, Imaging technologies like HDR, hi color gamut, etc).
- A driver of the Internet growth and its democracy.
- Very high electricity consumption, not very environmental
- Higher production costs, data storage, CDN costs.
- Limited availability of 4K content.
- Very limited ability to provide true 4K experiences over the Internet due to current technology gaps.
- Overloading the already highly congested Internet.
- Is the content I like watching available in 4K ? or is it going to be available in my region any time soon?
- Does my broadband connection and ISP internet Quality-of-Service enable 4K? (At least 30Mbps, consistently).
- On the flip side: Do I want to risk buying a 4k TV now and being stuck in the future? Perhaps in 2 years, when 4K does become the standard? (Similarly to being stuck with an "HD ready"/720p TV today)
Size can matter, and more pixels are better, all things being equal. However, just like the above examples, it is not the only factor to consider when it comes to a quality experience.
We believe that these are some of the specs you should keep an eye on that will take us closer to that experience:
1. HDR (High Dynamic Range) – Techniques to reproduce a greater range of luminosity, or brightness, by capturing multiple images of different exposure levels and combining them, thus gaining back some of the loss of detail in bright or dark areas of the image.
2. Higher Frame Rates – This is the frequency that frames change. Higher frame rates are important for fast moving motion pictures – e.g. sports, action
3. Higher Color Gamut – This is the range of colors that are represented.
4. Wider Bit Depth – Bit depth is the same as color depth; the number of bits used to represent a color of a pixel.
We recommend getting past the fixation on resolution and pixel counting, and paying more attention to the above specs and especially HDR, which we believe is the next big thing.
Mr. Zanger believes that the Internet will eventually give users infinite access to content, without boundaries of geography or popularity, and that the challenge facing the industry is to develop and tap business models and technology that make it possible and profitable to deliver any content, to any user, anywhere.
