what is Google Chromecast

 

what is Google Chromecast, what does it do?

 

 The Google Chromecast is a small but powerful streaming device. Google. Google Chromecast is a unique device that plugs into any TV or monitor with an HDMI port, and can stream content from your phone or computer onto the big screen  


In 2016, Google introduced the Chromecast Ultra, which works identically to its predecessors but offers the ability to cast 4K streams. Chromecast Ultra also supports Ethernet as well as Wi-Fi connectivity, to ensure you have a good enough connection for those more demanding streams. Chromecast Ultra is still used, as it's the device to get Google Stadia onto your TV.


How does Chromecast work?

The important thing to realise about casting is that it isn't about sending the content from your phone to the Chromecast dongle. In the vast majority of cases, all you're doing is using your phone to tell the Chromecast device what content to play by pointing it at the source. Chromecast then uses its own connection to retrieve that stream in the best quality it can.

That means that if you connect a Chromecast Ultra to a 4K TV, for example, it will play 4K content that you can't view on your phone.

However, if you're mirroring your phone on the TV, or viewing a website, then you're sending that directly from your phone or computer directly to the Chromecast and both need to stay connected. This is the case if you're casing your Android device screen, a tab from Chrome or your Chromebook desktop.

Requirements

In order for Chromecast to work, you need to plug it into an HDMI input on a TV/display, as well as connect it to a power supply. On Chromecast could be a USB socket on the back of your TV. For Chromecast Ultra it has to be a wall socket, or there isn't enough power for it to work.

You also need a compatible Android device or iOS device with the latest version of the app - now called Google Home - installed, or you need a compatible Windows computer, Mac, or Chromebook with the latest version of the Chrome browser installed. The Google Home app is the same app you use to control other Google hardware, like Nest Hub, and to setup smart home features to control via your phone.

 

 "We have to realize that we are not all the same," says Mark Tullis. He's president of The Social Media Landscape and co-creator on A Better Tomorrow. (I'll talk to him about this later.) We know there will always be different needs for YouTube — people using phones or laptops while watching TV; folks who want a smaller screen but no need a larger one in their home where they can interact with video without removing something from the wall. But as these screens become more common over time, too many older mobile devices make good substitutes such like Amazon Fire HDTVs.
