What is Cast Screen? & How to Make Use Of It.

Wao! It’s another Techy Thursday… How much of your Smartphone do you know? Let’s discuss about Cast screen and how you can use it.

What is Cast screen?

It is a tech that allows a person to display whatever is visible on his/her device's screen on another screen, mostly wireless using WiFi as a medium for sharing the screen.

Screen cast varies with different companies-Intel has their proprietary Intel Wireless Display (WiDi) for Laptops, Apple has its own Airplay protocol, and there is indeed an open standard too-Miscast, which is what any Android/Windows Phone with the "cast screen" button utilizes.

How Does it Works?

1. Make sure you are connected to the same Wireless LAN/WiFi network on both devices

2. Turn on the screen mirroring feature on the display you want to cast to, the host display starts a program that acts as a "server" to handle the exchange of screen casting data. If there are more devices connected to that Wireless network, they’ll equally be display.

3. Press the "cast screen" button on your phone or tablet, and it will try to identify all devices that are on the same WiFi/WLAN network and are running a screen cast server on their system. 

3. Now once both the device and the display have been connected, a cast screen connection will be initiated. The device uses programs to record its own screen and sounds and encodes them into the H.264 video format, which can be streamed or sent to a display immediately at the same time as recording-YouTube and almost every video website uses H.264 to serve videos to mobile devices. 

Think of your phone casting the screen as a live video transmitter and your display as a live broadcast video player. Since our transmitting device and our receiving player are on the Wireless Local Area Network part of your WiFi connection and not the Internet, they are attached to each other as if connected by physical cables-which makes the screen cast process fast enough to display live images on both screens at the same time.

How to Mirror Your Android Device to TV

To Mirror your Android device to TV set, make sure your TV set is Miracast supported.

Apple Users

If you use an Apple device, from your home screen swipe up and you’ll see AirDrop/AirPlay which allow you to Mirror your device to Apple TV box.  Do note there is only one way to mirror your screen: if your display is attached to an Apple TV box. 

YouTube TV (http://tv.youtube.com) is a specially designed YouTube website which allows phones or tabs with the YouTube app to remotely link together.

This is the Breakdown of understanding how your Android Mirroring works.
