Chromecast: what it is, how it works and what you can do with it

Let’s explain everything you need to know about Google’s Chromecast, explaining what this device is, how it works, and what you can do with it. It is one of the most successful and well-known hardware products in the company, which greatly facilitates the sending of your mobile content to the TV.

Let’s start by explaining exactly what Chromecast is with its basics, and then we’ll go deeper to explain to you in a simple way how this device works. Finally, we’ll end up with a list of over ten features of all kinds you can do to get the most out of it.

What is Chromecast


Chromecast is a device manufactured by Google,and with which you can send content from your mobile, tablet, or PC to the TV on which it’s connected. With this, if you have found a video on YouTube that you want to share with the rest of the room or watch on the big screen, you can do so in an extremely simple way.

The device itself is what is called a dongle,which is very similar to a USB skewer, but with HDMI connection and a small computer inside to do its functions. What you have to do is simply connect this HDMI skewer to the TV,link it to your home WiFi connection and send content.

And these are two of its main advantages, you don’t even need to connect by cable to the device from which you want to send content or you don’t have to browse any internal skewer operating system as with the Amazon Fire TV Stick and some of its alternatives. Just tap the sync button with your mobile device’s Chromecast and you’re done.

But that doesn’t mean your Chromecast is fully wireless, as it has a power cord with which you have to connect it to a plug. Once you’ve done so and set up, you’ll be able to send content from Android devices starting with version 4.0.3 for mobile or tablet, iOS starting with version 7.0 for iPhone, iPad and iPod, Chrome browser, and computers running the ChromeOS operating system.

How Chromecast works

To understand how Chromecast works you have to understand two concepts. The first is DLNA a technology to communicate devices over a network that is configured within your home network, which means that all devices will need to be using the same WiFi or Ethernet subnet. Everyone will need to support DLNA, and there must be a server-side device to deliver content, while the rest act as receivers.

Y el segundo concepto es el de Miracast, una funcionalidad que permite mandar mediante Wi-Fi Direct (tecnología que sirve para la conexión punto a punto de manera sencilla entre dos dispositivos) dos dispositivos Android prácticamente en tiempo real, y con un retraso ínfimo.

El Chromecast es un dispositivo que utiliza una tecnología en la que se mezclan los conceptos de DLNA y Miracast, un protocolo al que han llamado Google Cast. Con él, el Chromecast permite que podamos iniciar y controlar la reproducción que está realizando a través de otros dispositivos de forma inalámbrica.

The icon that identifies this technology and the supported apps is the one you see above. All you have to do is set up your Chromecast from the Google Home app, and once you’ve clicked on this icon you see above within the supported app from which you want to send content and choose the Chromecast you want to send it to.

Once the connection between your mobile, tablet, and computer and Chromecast is established, your device automatically becomes the remote control. In apps like Netflix or YouTube, you only have to tap on the content you want to watch, and instead of playing on the device itself, it will do so directly on the TV where you have the Chromecast.
