What is 4D TV – no Not 4K

What is 4D TV thumbnailToday’s topic is on 4D television.   No, not 4K, which I recently talked about in another video – but rather 4D TV.


Allow me to give you an overview of what 4D TV is all about.


Just to alleviate confusion, first off – let me give you a quick recap on 4K television.


4K is the latest resolution standard that has made its way to market.


The K stands for 1,000 so in other words we’re talking 4000 as in 4000 pixels.  It’s these small pixels or little dots of information that provide your television screen resolution.


The highest HD quality television set which is currently widely available is 1080.


The 4K manufacturers have pulled a bit of a switch on us in the naming structure.  Sets are currently referred to using the height figure.  For example, a 1080 television is 1080 pixels high by 1920 pixels wide.


That’s 1080 times 1920 pixels in total.  Over 2 million pixels of information.  That is why you have such amazing clarity in the picture quality on a 1080 High Definition television.


Now we move on to 4K which has a picture resolution approximately 4 times the quality of 1080 HD.


There is currently no single accepted 4K standard but at the highest resolution of 4096 pixels wide by 2160 high, we’re talking more than 8 million pixels.  Absolutely phenomenal clarity.


OK, so that’s 4K – Now, back to 4D TV – how is that different from 3D.  As you’re aware when we talk about 3D, we’re talking about 3 dimensions.  Television is basically 2 dimensional.  Much like a piece of paper you have width and you have height.  What 3D throws at you is depth.  This illusion is achieved thru the use of special goggles or glasses the viewer must wear which gives the special effect of depth perspective.


After giving the viewer the feeling that the objects on the screen are actually leaping out of the tv set – what can be left to experience.  How about placing you, the viewer, right inside the scene.  This is what 4D television does by attempting to stimulate more of your senses than just sight and sound.  4D brings in the kinesthetic sense of touch.  You are now made to actually feel what’s going on in the scene.  You are immersed in it.


The additional movie-going involvement is done thru the use of moving seats, sometimes with rollercoaster like movements, fans which suddenly howl like the wind or mechanical misters which can re-enact an ocean mist.


Some theatres have even gone as far as to incorporate smells into the presentation.  Sometimes with less success than hoped for.  Bad odors have a way of lingering…


4D has been around for a while.  As early as 1984, with the release of a movie in the United States called Sensorium.  4D productions have continued sporadically all thru the years however these have always been in theatres which must be willing to endure the higher cost of setting up the viewing suites with all of the additional technical gear.


Having 4D television in your home is another matter.  Technology never stands still for long.  That’s what makes life so exciting.  It is always hard to know what’s waiting around the next corner.  New television technology is a BIG money game. Corporations like Sony, Samsung and Panasonic all have huge R&D budgets and their engineers are always trying to create the next big THING.


Will 4D television be the next big thing after 4K or maybe even 8K, in my opinion I highly doubt it.  I personally feel it’s too gimmicky – but hey gimmicks have worked before so who knows.
