Chromecast
Google Chromecast is an audiovisual (multimedia) playback device for devices, especially older network televisions, manufactured by Google
It was officially announced on July 24, 2013 along with its Nexus 7 line of tablets, at an event in San Francisco
Like the previous Nexus Q, all its components are manufactured entirely within the United States
Basically it is a Wifi access point, with interchangeable USB and HDMI plugs, which once connected to a television with HDMI input and configured the Chrome web browser from a PC or an Android mobile phone, replicates the web pages that are viewed to the television; In the case of YouTube and Netflix, they send the video signal
Google made APIs available so that any video player can interact with Chromecast in the future

On September 30, 2020, Google presented the fourth generation of Chromecast, which for the first time would have remote control and the Google TV operating system, based on Android TV and in 3 new colors and includes a USB-C port, instead of the USB used by the previous
Software
Chromecast uses an operating system specially designed for the device, in which Miracast is used to display content; The system is composed of the following parts:
- Starting screen: this is displayed when content is not being sent
- Application screen: this shows the content sent
Functioning
Thanks to Chromecast, a mobile device becomes a personalized remote control
Mobile phone apps can be used to search and navigate, as well as play and pause content, rewind playback, control volume, and even create playlists
While sending content, you can use your phone for other functions
The Chromecast can be comparable to the “extend screen” function of some operating systems; this means that at no time is the Chromecast's memory used to store applications
Using the Android SDK, it is programmed together with an Android or Chrome app; this means that it must (for now) be accompanied by an app (for Chrome or Android), since the device does not have an application launcher
Also, Chromecast can be used as a wireless display using its Chrome extension (or Chromium based)
Generations
First generation
It was the first presented by Google, it had the appearance of a black pendrive, with an HDMI output that could be connected directly to the computer or television or through a short cable included in the box
At the beginning it did not have any graphical interface, today it has a screensaver that is activated when not in use, the screensaver searches for photos on the internet and displays them along with the time and name of the device
It also had a micro USB input for power and a button that allowed you to reset it after holding it down for 25 seconds, it also had an LED that indicated the different states of the device (solid white meant that everything was working correctly and flashing white meant that there was no internet connection)
It is currently discontinued and it is not possible to buy it
Chromecast Audio
The Chromecast Audio is an externally the same device as the second-generation Chromecast and on the inside it adds a sound processing chip
This Chromecast can't stream video, it can only stream audio
It does not have an HDMI connector or any type of video output interface, its only output is a 3.5" jack and inside it an optical audio output
It is currently discontinued and it is not possible to buy it
Second generation
The second generation was launched two years later, in 2015
Its exterior design underwent a major change as it took the form of a circular disc slightly larger than the UMD (Universal Media Disc, a type of optical disc developed by Sony, known mostly for its use in the PlayStation Portable)
The name "Chrome" was no longer inscribed, the 3D logo was now integrated
The HDMI was not integrated, a cable came out and at one end the connection pin
The micro USB input, the LED (with the same states as above), and the reset button are retained
It is currently discontinued and it is not possible to buy it
Third generation
Chromecast 3
It didn't add big improvements apart from being 15% faster than version 2, its WiFi AC added more speed, we could choose between dark gray and white, when before only the former was available
In the updates section, Google added support for Home, being able to control it by voice if we have a Home device at home
It premiered in Europe at a price of €39, while weeks earlier in the United States it went on sale at $37
Chromecast Ultra
With the arrival of 4K resolution to television broadcasts over the Internet on platforms such as Netflix or Wuaki TV, the need is created to bring a new device to the market, which in addition to supporting this resolution, improves data transfer and therefore, video loading times, and the overall response of the device
It was released in Europe in November 2016 at a price of €79, while weeks earlier in the United States it went on sale for $69

In addition, it comes in 3 new colors (Blue, White and Pink) and includes USB-C port
This new generation of Chromecast, in addition to supporting 4K resolution, also has support for Dolby Vision and Dolby Atmos
The official name of this generation is "Chromecast with Google TV" (USA/Mexico) being the first not to have the name "Google Chromecast" and the first device to have the Google TV system, which will replace Android TV in the following years
