Wireless transmission technology saved the TV?

Going to a friend's house as a guest, everyone is congratulating you on raising your dad and want to see what your baby looks like. Ordinary young people will most likely take out their mobile phones and show them on that 4.3-inch screen. Everyone squeezes their heads and they want to see if this guy looks like a dad or a mom. Literary and artistic youth will print a dozen photos taken with Fuji Polaroid, and there are graffiti on it, and it is really sober and cute. The Youth of Science and Technology will turn on the TV and set-top box of a friend ’s house, and then sit on the sofa and project photos and even videos onto a 42-inch large screen through a wireless transmission protocol, which is an absolute bunker effect.

In fact, the biggest enemy of home digital entertainment has always been messy data lines and complex controllability. The emergence of DLNA, AirPlay, and Miracast wireless transmission solutions has made your mobile phone or tablet in your pocket or handbag quietly become the next generation. Entertainment center, these highly personalized and socialized devices can bring hundreds of thousands of interactive applications, making the TV that has become a supporting role re-attractive.

Apple one step ahead

I believe that there is not much knowledge about Airplay technology in the fruit powder. Many people also learned that the iPhone and iPad can still play like this because of the recent attention to the Xiaomi box.

To be precise, Airplay is a multimedia communication protocol developed by Apple. In a WiFi environment, a special "language" between devices. From the perspective of working principle, because the bandwidth of WiFi is several times that of Bluetooth, it is currently the widest and most stable carrier of wireless transmission distance, so AirPlay can fully exert the linkage between various devices in home applications.

With AirPlay, wireless video / audio playback and even wireless printing are possible

In the dual-screen display technology, Apple has played well

What can it do? There are many transmission solutions for pure point-to-point audio, such as Bluetooth and 2.4G, but Airplay implements the interconnection between any devices in a local area network, the effective distance is farther, and there is no need for one-to-one pairing. Through the mirroring function of Airplay, you can map the content displayed on the screen of the mobile device to the high-definition TV. That is to say, you use the Youku client to order movies on the iPhone, and the TV screen can be displayed at the same time. At this time, the iPhone becomes a Network player, with functions such as browsing, selection, and navigation. Dig deeper into Airplay, you will also find that it has the potential for dual-screen applications. For example, in the game "Real Racing 2 HD", the iPad acts as a steering wheel, the game screen is displayed on the TV screen, and the iPad screen is used as an auxiliary screen to display the track position, Speed, ranking and other information.
