When was Miracast technology launched ? What is Miracast technology used for ? How does Miracast technology work ?
Miracast technology was launched in 2012 by the Wi-Fi Alliance, an organization created by hundreds of companies around the world that enables setting standards for Wi-Fi. Currently supported by many brands and devices, this Miracast system was originally called “HDMI over Wi-Fi”, but each brand went to a different naming path according to itself. For example; Named SmartShare for LG TVs, AllShare for Samsung TVs, Screen Mirroring for Sony TVs, TVs for Panasonic Image Mirroring. You can also find a list of Miracast supported products here (click). According to the statement made on the support page of the Wi-Fi Alliance (Wi-Fi Alliance) website, the link for Miracast supported devices can be used by 6135 devices according to the data of 27 September 2016.
The transmitter and receiver two devices to be transmitted must have Miracast technology, and if not, the Miracast adapter must be used via HDMI or USB ports. Screen sharing feature for smart phones is valid for Android 4.2 (Android Jelly Bean) and later operating systems. Microsoft announced the support of Miracast in June 2013 that it will provide support with Windows 8.1. This feature enabled Windows hardware to come with Windows 8.1 to offer Miracast support as package content.
Miracast is based on Wi-Fi Direct technology. Wi-Fi Direct technology, which we have witnessed especially on Android smartphones, enables two devices to establish a direct, end-to-end Wi-Fi connection, so they can automatically find and connect to each other without a wireless network router. Miracast does not stay connected to the network created by the wireless modem in your home, but instead creates its own network, enabling streaming content between paired devices.
Miracast is shown as an answer or alternative to Apple’s AirPlay technology. Support in the standard is provided by Android 4.2 and above devices, Micsrosoft Windows 8.1 operating system and later products. This means that a wide range of Android smartphones, tablets and Windows laptops, desktops or tablets can stream content from their screens to Miracast compatible receivers such as televisions, HDMI devices or set-top boxes.
Miracast uses H.264 encoder and 5.1 surround sound technology to project video in 1080p resolution. The DRM layer is also available, so a Miracast powered portable mobile device can project copyrighted content such as DVDs or music to a Miracast compatible receiver on its screen. Miracast can be simply described as a wireless HDMI cable. Without using a cable to connect the two devices, Miracast can stream the content you see on the screen of a device to a high resolution screen in real time. The same goes for the voice. Moreover, Miracast does this without connecting to the Wi-Fi network in your home. Currently, there is no need for a network other than Wi-Fi network between the two devices for image transfer.
There are two factors that can be considered negative in the use of Miracast. One of these can significantly affect the Android device’s battery life during image mirroring. As the distance between the two devices increases, the battery consumption rate increases. The second negative situation is that your phone needs to stay awake when you connect to the TV from your android device. For example, when you watch a movie, the TV screen will go blank as the phone screen will turn off after a certain period of time.
Miracast is not the same technology used by Google’s Chromecast or Apple’s AirPlay. In fact, many authorities argue that Miracast has a direct response to Apple’s proprietary system.
The most important benefit of Miracast is its widespread adoption in many different device types. Although most people have never heard of Miracast, the good news is that it is used quite widely.
