Let's look at 2 typical apps for the four screens.

Before the beginning of this article, let's look at 2 typical applications of the four screens. One is the number of electronic bands that have been set up to use the ipad in China over the years, each musician takes an ipad to sing while dancing, and the other is more people feel the shock of High-tech; the second is that Audi, the carmaker, has launched an Android-based on-board tablet that provides navigation, Network browsing, media playback and other functions.

What can you think of these two applications? Is this still the fourth screen that people are talking about? In fact, these two applications are not fundamentally different from the application of the family four-screen, except that they are placed in a particular space and become functional without networking. There is no internet connection between each of the four-screen individuals in the electronic band, the car application tablet, more like the home application scene of the mobile, you can use the plate navigation positioning and media options, such as the operation of liberation of the pilot's hands.

Take a look at some of the wonderful uses of the fourth screen: see the favorite star costume, the heart of the words on the point, the commodity information immediately on the "four screen" on; like the TV show only see half to go out to work, take the "four screen" on the road to continue to see; A little "screen four" becomes a videophone. In these scenarios, the first is fully applicable to the physical store, the second is now implemented, the third, in addition to the fourth screen with voice call function, there is no better equipment to achieve. What, yearning?

The "four screens" concept was born soon, the fourth screen refers to the TV screen, mobile screen, computer screen, other than the fourth screen, also known as "family information four screen", in fact, this concept in many cases will be confused, several screens in a certain scene can be transformed, and the new technology will change the situation, Then the four screen will vary depending on the carrier.

In fact, many of the current scenarios can be summed up to the fourth screen, but people do not realize that most of the time to talk about the fourth screen can be called "family four screen." It boils down to the fourth screen, no matter what the scene, the main link is whether the network, whether WiFi or cable, as long as the network can be guaranteed to play the function of the Forth screen, such as KTV inside the song, generally by twisted-pair to connect the rear of the host, although it looks more like a computer plus a monitor, But it also achieved the launch of the VOD song, is not the fourth screen?

There are two features in the four screen: one is replaceable, mobile phones and other terminals are slowly with the function of the four screen, now also can replace the four screen to do albums and video content of the push, the future may also be replaced by intelligent voice control, a word can be carried out, what need to manipulate? At the same time, the fourth screen is also expanding to several other bottles, For example, the voice call function of the fourth screen can replace the mobile phone; the second is the narrow, also said the application of the smaller the more can show the advantages of the four screen, the current people put forward the fourth screen application is generally set up a family or units, large scenes unless open WiFi or a considerable number of network equipment, To display the content of the four screen on the specified device.

Based on the above, from the point of view of the network, the fourth screen should be included in the category of things, no network of the fourth screen is only a personal flat, you can separate network, but can not achieve content and turn screen functions, can not meet individual needs.

As part of the Internet of Things, the fourth screen is compared with the two-dimensional code, two-dimensional code just stores the general information of things, users can only see the text after scanning, is a static display; the performance of the four screen is much more, belong to the dynamic display, on the one hand, through the text, voice and video and other ways to explain an individual, On the other hand, the fourth screen of the access network is more like a control center, can be put on a number of screen display content, or by sending instructions to control the operation of other functional equipment, so, the fourth screen's more important significance lies in the simulation control center, is not simply the content to put.

In this sense, some businesses are developing the overall home control unit is also in the category of the fourth screen, more role is to regulate other equipment, the difference is that the screen is a microcomputer rather than artificial control, of course, if the semi-automatic state, it is the same as we say four-screen concept is the same.

The four screens are not so closely related to the other three. Each screen can be independent of the Internet as a terminal, if you can have a product to connect 4 screen, it is equal to these 4 screen can become a large number of Internet users of this product, may also become the future flow of many contributors to a member, As we all know, this product is now the TV box and TV Stick.

The current discussion of the four screen some of the views are attributed to the relay equipment, the topic is basically locked in a variety of boxes and TV bars, to tell the truth this thing in my opinion is only a transition products, you can make the current stage of the ordinary TV network, and further networking with other devices, the Internet is gradually After the public has changed Internet TV, this product will eventually be eliminated, which is why many companies are pushing internet TV.

The application of the fourth screen in addition to the family and the cases mentioned at the beginning of the article, there are many applications of the possibility, technology companies should be more distant vision, not only limited to the family of this application scenario, as long as the thought of more user needs, to explore better ideas, access to more users.
