Can TV multi-screen interaction really improve the user experience?

TV-centric multi-screen interactions have become increasingly popular with the rise of smart TVs. In just a few short years, the vast majority of smart TVs on the market have been equipped with multi-screen interactive features. However, due to the different interconnection protocols used by manufacturers and the low degree of software optimization, the multi-screen interactive functions of different TVs in the market are also very different. So now that the multi-screen interaction of TV terminals is to enhance the user experience, or is it a tasteless feature?


TVs, computers, and mobile phones are the three most common platforms for everyday users. They have their own characteristics: they have a large TV screen and a good viewing experience; they have many computer functions and are rich in storage space; mobile phones are the most convenient to carry around. Users use TVs to watch videos at home Although the viewing experience is good, they are far from mobile phones and computers in terms of operation and content resources. The emergence of multi-screen interactive technology aims to integrate the advantages of the three platforms to achieve the best user experience.


Although the current multi-screen interactive protocols include DLNA, WIDI, AIRPLAY, IGRS, Miracast, etc., the final implementation can be roughly divided into three categories: One is the small screen to the big screen, that is, the mobile phone, Contents of smart terminals such as tablets are played on large-screen televisions. The second type is a large screen to a small screen, watching the contents of the television on a mobile phone and a flat panel. The third category is the mobile phone remote control, through the mobile phone and tablet to complete the various manipulations of the TV. Next, the author will classify and discuss the actual effects from the specific multi-screen interactive forms.
Small screen to big screen push is king

Turning a small screen to a large screen is to put content on a small screen such as a mobile phone or tablet into a large-screen TV for playback. Users who have used smart TVs know that video on-demand video resources are very limited compared to mobile phones and computers. Many of the latest and hottest video content networks can be seen everywhere, but it is hard to find on TV on demand platforms. Take the legendary hit Wu Mei Niang, the vast majority of Internet TV platforms do not support free viewing. Small screen to large screen direct access to the Internet through mobile phones, and then watch the content on the big screen TV can greatly enrich the content of the TV.


Although the small screen to large screen can use mobile phones as an intermediary, allowing users to watch more abundant content on television. However, in the actual use of the screen, there are many problems with the screen. Now the small screen to the big screen can be specifically divided into mirror and push two forms.

Mirroring TV is a large display for mobile phones

The small screen to large screen mirror image, as the name suggests, is to copy the contents of the mobile phone screen to the TV. The TV is like an oversized display of a mobile phone and can project all the pictures on the mobile phone in real time. Just blending the convenience of TV screen and mobile phone, users can watch various online videos on the big screen of TV, and also can play various smart games on the big screen.


However, in the mirroring function, the TV is just a second monitor, and all operations and processing are done by the mobile phone. During the broadcast of the program, the phone receives the phone or the information will be directly displayed on the big screen. In the meantime, the mobile phone's screen-out, view of messages, and browsing of the circle of friends can all lead to interruptions in the content of television broadcasts. The simple things that many people are used to watching while watching TV, such as WeChat and brushing a circle of friends, have become unachievable.

And when mirroring, we are watching a large-screen TV, but the screen of a small-screen mobile phone must also be displayed synchronously, which will quickly consume the power of the mobile phone. In addition, the screen image of television is often not as clear as the screen of the mobile phone itself.

â—†Advantages: rich content and convenient operation

â—† Disadvantages: The phone can not perform other operations consume battery power

Push function stability needs to be improved

Unlike mirroring, the mobile phone is only responsible for the selection and control of content in the push function. The function of acquiring network information and decoding is accomplished by the television. In the meantime, the mobile phone can completely blank out the screen as well as answer calls, open applications, and other operations, and will not affect the playback of TV content, nor will it display your personal information on the big screen of TV.



Pushing such a small screen to a large screen is definitely a very successful way of multi-screen interaction, but the push of online video requires the interconnection of television and mobile clients. Although the TV customized client can perfectly support, the video resources provided therein are not very rich. The compatibility of third-party video clients and TVs is not high, and even if they can complete the push, they will be very unstable.




Big screen to small screen, practical but not commonly used <br> Big screen to small screen is not to enrich the TV content, but to increase the portability of live TV content, but also through the touch screen to control the smart TV. Although network resources are abundant, many important competitions and premiere content are only broadcast on cable television. Although some content networks have live broadcasts, their picture quality is not high and there is a long delay. Through a large screen and a small screen, we can watch TV broadcasts on our mobile phones even if we cook in the kitchen, without delaying any exciting moments.


Now more and more smart TV features, but the operation is basically continued the previous remote control button control, compared with the mobile phone touch screen far away. The large screen to small screen pass in the specified mobile phone client support, not only real-time display TV screen, but also through the touch screen slide, click to complete the complex operation of the smart TV. Especially for text input, the efficiency of the touch screen on the mobile phone can be greatly improved.


The meaning of a big screen to a small screen is reflected in the live broadcast of the TV, and the mobile phone touch screen to control the TV. In particular, in the face of smart TVs, which are now becoming more and more functional, it is possible to accomplish various operations through the display of mobile phones and the basic operation of mobile phones. In particular, complicated operations such as text search can greatly improve efficiency. It can be seen that the actual experience of the large screen to small screen is still very good, but due to the reasons of the concept, many users are not accustomed to this operation, but there is no doubt that this multi-screen interaction can create great convenience for users.

â—†Advantages: more convenient to view the live touch screen anytime, anywhere

â—† Disadvantages: Support for less television

Mobile phone remote control is easy to feel but not good <br><br><br><br><br><br><br><br><br><br><br> The other way of multi-screen interaction is mobile phone remote control. By installing the mobile phone client or binding WeChat, you can complete the operation of the remote control on the mobile phone. Under the network condition, controlling the TV does not need the remote controller at all, and does not need to worry about the situation that the remote controller cannot be found. In addition, through multi-screen interactive mobile phones can also act as a gamepad and voice microphone, the function is quite rich.


Although the mobile phone can achieve various operations of the remote controller through multi-screen interaction, the touch and convenience of use is not as good as that of the remote controller. Now the screen of the mobile phone is also relatively large, and most of the single-handed grips are not very comfortable. The remote controller can be easily mastered with one hand, and it can be operated blindly after being familiar with it. A multi-screen interactive remote controller can still play, but it is not realistic to want to replace the remote controller.


Advantages: easy to use, feature-rich

Disadvantages: feel bad

â—† Summary â—†:


       The norms of multi-screen interaction are not uniform, and there are many homes in either technology or form. If the television in the market is generally speaking, the actual experience of multi-screen interaction will not satisfy people. It is not that there are no good solutions for multi-screen interaction, but instead, such good forms as push functions, small screens, and large screen functions have not been developed and promoted. On the contrary, some forms of multi-screen interactions that are not perfect have continued to spread, making the entire multi-screen interaction implicated.


The advantages of multi-terminals for televisions, computers, and mobile phones can be combined, and multi-screen interactions actually have great promise. Multi-screen interaction can not improve the user experience, but only for the current status of smart TV. If functions such as push, small screen, and large screen are popularized, stability and compatibility have been further improved. I believe that multi-screen interaction can definitely create a brand new intelligent experience for users.
