The popular Wi-Fi CERTIFIED Miracast technology, better known to most users by its short name Miracast, belongs to the WI-FI Alliance. The technology was officially approved in September 2012. Miracast is a new standard for wireless multimedia transmission. Widely used WI-FI Direct technologies were used as a basis, but many differences and improvements distinguish Miracast from other similar solutions.
The developers' main goal was to significantly simplify the new technology. This allows any owner of a modern smartphone, tablet, or laptop that supports Miracast to play video or display game content on a compatible large-screen device, and this can be done with almost one touch and without using a cable. Today, most major global manufacturers equip their mobile devices, laptops, and LCD panels with Miracast technology.
In simple terms, this technology allows you to mirror everything that happens on a phone, tablet, or laptop screen to a large screen, for example, a TV. It's more or less the same as if you connected your device to your TV via HDMI, but everything is wireless.
The complete absence of a wired connection has become available for modern monitors, TVs, and projectors. Using Miracast technology, it has been possible to expand the potential possibilities of the usual display method. This technology is available to every user and is extremely easy to use, fully open and compatible with any platforms and devices from different manufacturers equipped with Miracast products.
- wireless content transmission based on the IEEE 802.11n standard;
- direct connection without the participation of a router;
- minimized delays and synchronization during signal transmission;
- the ability to transmit content in 3D;
- simplicity of customization and interaction.
To transmit using a specific technology, only two enabled compatible devices will be needed. One acts as a transmitter, and the other acts as a receiver.
Similarly in functionality, solutions also require a Wi-Fi router, which causes a number of specific and known inconveniences. For example, if a user decided to play online games, and the other to watch a movie in HD quality with the content transmitted via the router on the TV screen, then certain problems will face both users. The problem is a lot of data to be transmitted over the network, as well as from the settings of the router itself. In the case where gaming traffic is prioritized, the movie will be played with a noticeable delay. If you prioritize the video stream, you will experience problems with the game.
For example, you can broadcast a movie from your phone to your TV using DLNA technology, but the fact is that this technology allows you to display only a large number of multimedia files (videos, movies, music). The connection goes through a Wi-Fi router. Miracast technology allows you to display everything that is visible on the screen. This includes displaying the image during gameplay.
This technology works according to a fairly simple scheme. Miracast-enabled devices communicate with each other using a special program (if you set up broadcasting from a laptop) or through a special item in the mobile device settings. The next step is to activate the necessary playback mode: video playback, displaying a mirror of the smartphone screen on the screen, etc.
Connected devices using Miracast technology communicate directly and can independently create a secure and independent channel that can provide video information. Miracast can be called a kind of superstructure over Wi-Fi Direct. This technology uses the H.264 compression standard, which allows for the transmission of video signals in Full HD (1920 x 1200) format and multi-channel 5.1 audio in AC3 format.
Miracast technology's capabilities are not limited to just transferring multimedia files played from one device to another. The technology allows you to display a full copy of your mobile device's display on a compatible TV or monitor. It is worth noting that the function of working in the opposite direction is implemented, which allows you to play the image from the TV screen on the display of a mobile gadget.
Miracast is an inexpensive, convenient and very promising direction. This is proven by the significant support of this technology by giant companies Intel, AMD, NVIDIA, Qualcomm, MediaTek and others. Many users already consider Miracast a worthy alternative to the familiar HDMI cable or Apple AirPlay technology. Gamers have appreciated the new wireless capabilities, as the arrival of Miracast has made it even more advantageous to use a tablet as a game console.
If you already have devices that support Miracast, we strongly recommend trying out this great development. If you don't have such gadgets, don't worry. This technology has the potential to become a mandatory solution for all modern devices and displays in the coming years.
