Buy 4K? or recite recite.

The World Cup is over, although the Netherlands has only three personal support, but has been counted on fans (fans), I think the two teams perform well. Using the latest television to watch the waves is really shocking, but the wave of commentary is left to the sports version of the experts. The World Cup has a lot of technology this year, for example, for the first time, the introduction of the detection of soccer cross-line technology, through each goal after each installation of 7 units per second can detect the speed of up to 500 frame camera, to measure the movement of the football device, tracking all the moving objects on the football field, as long as the system detected football across the will send a message within 1 seconds to the referee in the court.

In fact, the U.S. NBA has long used Google Glass to use motion capture technology, I think the court decision is interesting, but sometimes too dependent on technology, will lose the "man-made" factors and errors, although accurate but also rigid.

However, of all the techniques, I am more concerned about 4K. The last World Cup, Sony advocated 3D image technology, from the early stage of filming to post-production and broadcasting, can provide one-stop complete matching, but 4 years of technology used in cinemas can also, at home level or dispensable. This time 4K they have a full set of configuration, and also prepared 3 to 4 K resolution of the global broadcast, unfortunately for the local television stations, the response seems to be mostly cold, for internal testing mostly.

4K imaging technology, from the announcement to the launch has been more than two years, however, after the market has been applauded not draw, a large extent is the promotion and sales are not too dare to increase the strength of the promotion, the reason is very simple-there is no source and broadcast support, the pursuit of the technology will inevitably have reservations. As far as the industry is concerned, none of the uniform standards seems to have a greater impact. Last week, the Consumer Electronics Association CEA (Consumer Electronics Association) began to redefine and define the Ultra HD imaging technology, which mainly updated the three requirements of resolution, display frame number and decoding specification. All of these high-definition TVs, monitors and projectors will have to meet the following three standards.

UHD High-definition TV must support the 1080p source to the hard to 3840x2160 resolution, and a group or above to support the 4K 24/30/60 frame playback of HDMI 2.0, as well as support 4K broadcast and source must decode the specifications HDCP 2.2 DRM. In other words, if the 4K equipment in your home lacks the latter two technical specifications, very likely in the future transition less than the real 4K, if there is no clear specifications, as well as a more complete package, the individual feel that it is not time to go into the market, because as long as any changes in specifications will make your equipment become useless, And 4K TV is by no means a cheap product.

On technology, the 4K does add to the large size of the TV is prone to particle problems, and the image of the shock is even greater, but the factory was a bit impatient to push 4 K, in all there are unknowns in the case of the introduction of a little waste, should be more certain, 4K to popularize.
