Therefore, considering in its entirety the Chromecast line, the main characteristics of these devices will be mentioned below:

It offers two methods of data transmission. The first makes use of the technology of smartphones and tablets and of applications that support Google Cast technology. While the second is responsible for reflecting the content of the computer’s Google Chrome and that of multimedia content on certain Android devices.

It has an initial menu that is personalized according to the user’s preferences, which is called “Backdrop”, and it reproduces various sets of multimedia files such as photos, satellite images, news, weather reports, etc.

Chromecast dongles are powered by USB or micro-USB cables. However, those video transmission dongles must also be able to connect to an HDMI port on an HD display.

Chromecast dongles of the first generation are characterized by being physically similar to black USB sticks with HDMI outputs, LEDs, and a reset button and by having a simple interface that works as a wallpaper. They use the Wi-Fi wireless connection standard 8802.11 b / g / n (2.4 GHz), with WEP, WPA / WPA2 security. They have 512 Mb of DDR3 RAM and 2 Gb of internal memory.

Second-generation Chromecasts resemble circular discs that have an HDMI cable with plug, micro USB port, LED, and reset button. They feature a 1.3 GHz dual-core processor, 512 Mb of RAM, and 256 Mb of internal memory, with a Wi-Fi standard 802.11 b / g / n / ac (2.4 GHz / 5GHz), WEP security, WPA / WPA2, and a basic interface.

Chromecast Audio are externally similar dongles to second-generation Chromecasts, although internally they have a sound processor. This device can only reproduce sound, so it does not have an HDMI connector or video interface.

The Chromecast Ultra are dongles capable of streaming 4K multimedia from platforms like Netflix, YouTube, etc. Therefore, it is able to improve data transfer, thus reducing video loading times and dongle reaction.

However, it maintains the standards of wireless connection, security, and HDMI of the third generation.

All generations use the mDNS (multicast Domain Name System) protocol to search for devices on the Wi-Fi network.

The Chromecast operating system uses Miracast to cast content. In addition, it is updated automatically without issuing notifications.

The Google Cast technology that enables applications to use Chromecast dongles is based on the Software Development Kit (SDK). In turn, this technology is composed of an issuing application based on the device’s operating system, which is used by the user; and by a receiving application that runs in an environment similar to that of the Chrome browser.

How does Google Chromecast work?

Essentially, Chromecast makes the mobile phone or computer work as a personalized TV control that allows you to view the multimedia content of the device, regulating the volume, creating a playlist, pausing, and rewinding the playback, among others. To make this possible, Chromecast uses DLNA and Miracast technology, making up what is known as Google Cast.

DLNA is the Digital Living Network Alliance, a tool that allows you to create a network within a home network, using Wi-Fi wireless connections. While for its part, the Miracast is a P2P (peer-to-peer) network that is embedded in the specialized Chromecast software, which allows the dongle and the computer or mobile to communicate efficiently.

Google Cast, by combining the DLNA concept with the Miracast and the SDK, makes computer and mobile applications develop capabilities to enable communication with the dongle, since transmitting and receiving applications intervene. For this reason, Chromecast is dependent on Android or Chrome applications supported by Google Cast technology to function, since it does not have its own application.

Chromecast does not completely take over the mobile or computer, so other functions can be performed while streaming multimedia content. Also, Chromecast memory is not used to store applications. Although it can be used as a wireless monitor of the computer if the extension for the Google Chrome browser is installed.
