What is Google Chromecast?

What is Google Chromecast - streaming with ease

What is Google Chromecast? It's one of the cheapest and easiest ways to stream video content right to your TV, from almost any device. And check out our Chromecast with Google TV review to meet its new big brother, which actually has a remote.

But back to the matter at hand: the $35 Google Chromecast is one of the best streaming devices because of that simplicity, which also enables you to share your phone or laptop's screen directly onto your TV. With a Chromecast, you also get a fast path to bring Netflix, YouTube, Hulu and many more services straight to the biggest screen in your house. But Chromecast doesn't work the same way as competing devices like Apple TV or Roku.

Use this FAQ to get up to speed on the basic Google Chromecast functions and decide if it's right for you. If you think it's not got enough, we'd say that the Chromecast with Google TV is the upgrade that your streaming habits deserve.

In the market for a new Chromecast? If you can afford to wait, we recommend buying one on Black Friday. On some sites, deals have already kicked off, and we expect more to drop earlier in the year than that standard post-Thanksgiving window.

What is Google Chromecast?

Chromecast is a device that you plug into your TV's HDMI port, powered by a USB cable (included). Using your smartphone or computer as a remote control, you can use Chromecast to access video content from Netflix, YouTube, Hulu, the Google Play Store and other services (Xfinity Stream just got Chromecast support). You can also use it to stream almost any kind of content from the Chrome browser on a laptop or desktop computer

Also, Chromecast support is baked right into plenty of apps you already stream from. Just look for an icon of a rectangle with curves in the bottom left corner. This is how the Cast icon appears in HBO Max in the top left corner:

When you see that icon, you know that the app you're using can stream to the screen your Chromecast is connected to.

When you're not streaming anything in Chromecast, it simply posts beautiful desktop backgrounds, in its Ambient Mode. You might notice quality dip, though, and a lowered frequency in new art. Google announced that it's making these changes to reduce stress on bandwidth, prioritizing traffic for video calls and other more pressing content.

Chromecast technology is also a part of the Android TV operating system. A recent update allows users to perform Chromecast app audio streaming in the background of Android TV.

What is the difference between Chromecast and the Chromecast with Google TV?

To put it simply: $20 and a heck of a lot of apps. The Chromecast with Google TV makes Google's streaming device a lot more like the Fire TV sticks and Rokus it's always competed with. 

The biggest difference is likely the interface, in that there is an interface. The Chromecast with Google TV has 6,500 Android TV apps for you to use, so you're not just relying on Chromecast support.

Also, there's a full remote for controlling your stream, so you can put down your phone and pay attention to what's on your TV.

What is the difference between Chromecast and Chromecast Ultra?

Google no longer sells the Chromecast Ultra, which was priced at $70 and can broadcast content at up to 4K resolutions with HDR color technology. 

In terms of channel selection and overall functionality, the two devices are identical. It's worth noting, though, that the Chromecast Ultra has a built-in port for an Ethernet cable, but also requires an external power source, rather than a USB connection built into your TV. You can also see how the Chromecast Ultra stands up to its competition in our Chromecast vs Fire TV vs Roku face-off.

Is there a Google Chromecast remote?

News surrounding a Chromecast Ultra 2 keeps popping up, including the fact that the Taiwanese certification agency NCC approved both a new Chromecast Ultra and a remote for that device. Then, we saw news of the FCC approving a new Google remote, and that its model number is very similar to the model number of the aformentioned Chromecast Ultra 2, which suggests that the two devices will be sold separately. 

This would make a ton of sense, giving the "we want a remote" crowd an option to upgrade while not forcing said remote on people who prefer using their phone.

Why would people want a remote? Personally, I'm always fighting the impulse to use my phone as I watch TV, as it's a big distraction from what I'm trying to watch.

How does Google Chromecast work?

While it might appear that you're sending the video from your device to the Chromecast, most of the time it's doing something more simple. Your connected device is merely telling your Chromecast what you want to play, and then the Chromecast will stream that media, using its own connection to the internet.

Of course, you can also use a Chromecast to mirror your phone, tablet or laptop's screen on your TV. This requires a lot more active intent, as your device cannot be put to sleep or unlocked, without the feed going down. Oh, and if your Chromecast is getting an update right now, get excited. The Chromecast will finally remember your volume settings, and the Google Home app is becoming a better virtual remote control.

Where's the Google Chromecast app?

Practically everything has an app, but there isn't a dedicated Google Chromecast app. Instead, you'll use Google Home (Google Play, iOS) app, where you have controls for your active Chromecast streams.

The Google Home widgets on both platforms are valuable for easy access to the controls you need for pausing and fast forwarding, though scanning through long movies and events can be very hard when you're tapping the on-screen progress bar.

Where is the Google Chromecast extension?

I spent way too much time looking for a Chromecast extension, but you don't need to download anything new to get Chrome to work with Chromecast. 

If you don't see a Chromecast button in the menu bar, just click the three dots button in the top corner, and select Cast. Then, you can see the available devices to send video to your TV.

To keep the button there, right click on the Cast logo and select Always show icon. 

What can I watch on Google Chromecast?

Chromecast has access to video and audio content from many services. Google keeps track of many of these on its official site, although there is no comprehensive list. Ever since Google released the software development kit for Chromecast, new apps have been springing up frequently, so keep an eye out for more apps.

Can I control Google Chromecast with my voice?

Yes. Previously, you needed to route your Chromecast commands through a Google Home device, but now, you can give vocal commands directly through Google Assistant. Google has complete Chromecast setup instructions, but the functionality is pretty self-explanatory. Simply connect your Chromecast and your phone to the same network, and you can cast music and videos to your TV with just a few words.

Can I travel with a Chromecast?

Due to its small size and easy setup, the Chromecast may seem like a boon for frequent travelers. However, Chromecast does not support captive portals — networks that require browser-based logins. As such, the Chromecast is not terribly useful in most hotels and universities. Still, if you do take your Chromecast with you and find a Wi-Fi network without a captive portal, changing the login details is not too difficult.

Are there any Chromecast alternatives?

Yes, but it depends how much you're willing to spend. A $30, a Roku Express will also allow you to stream content to your TV, although the device's design is not as good as the Chromecast's overall. 

An Apple TV costs $150 and functions much like a Roku box, but can also stream content (like games) from your iPhone or iPad to your TV. You could also stream content through a PS4 or Xbox One, but these devices cost hundreds of dollars.

How does Google Stadia work with Chromecast?

When Google Stadia, the company's game-streaming service, launches in November, Chromecast will initially be the only way to play Stadia games on your TV. (Unless, of course, you simply cut out the middleman and attach a computer to your television set.)

    Hello. I just found your article. I do have a question. Can I add apps to the Chromecast, like TerrariumTV since I do not have a subscription to sites like Netflix and Hulu? Please let me know. Thanks.

    I think you will need an android OS streamer to side load the app on. It's not available from the app store because it isn't legal.,news-27305.html
