Differences and features of Wireless Screen sharing protocols such as DLNA, Miracast and Airplay

       Wireless screen sharing agreement because sometimes bring many trouble to our vote screen operation, such as apple Airplay agreement allows only oneself and authorized equipment use, let many apple mobile phone search is less than the TV because the TV does not support Airplay agreement. So today I’m going to join you in popularizing what the major wireless sharing protocols are and what their features are.


DNLA is initiated by SONY, Intel, Microsoft, etc. Apple was also a member of the DLNA alliance at the time, but later quit and went its own way.

DLNA has similar features to Apple’s AirPlay, and the agreement is largely the same. They both allow media content from your phone to be delivered to your TV screen. The difference is that DLNA on the mobile phone does not have the mirroring function like AppleTV’s AirPlay, nor does it have the dual-screen gaming experience supported by AppleTV. At the moment DLNA is more about delivering photos and videos from mobile phones to the big screen.

The Miracast standard, developed in 2012 by the Wi-Fi Alliance, is a wireless display standard based on direct Wi-Fi connectivity. Devices that support this standard can share video images wirelessly.

Mobile phones, for example, can pass an Miracast to place a video or photo directly on a TELEVISION or other device. Unlike DLNA, Miracast also has an mirroring feature similar to AirPlay that puts the screen content of your mobile phone directly into an HD TV screen, so you can play a game through it. Because the technology is relatively new, equipment to support it has so far been scarce. And the technology is not mature.


AirPlay is a wireless technology developed by apple, which can wirelessly transfer pictures, audio and video from iPhone, iPad, iPodtouch and other iOS devices to AirPlay devices through WiFi.

AirPlay also has a special feature called AirPlay Mirroring, which works with the AppleTV to wirelessly transmit images from your iPhone or iPad to your TV, meaning that what your device shows on the TV screen is what it is, not just pictures and videos.


DLNA protocol: it is only applicable to push audio, video and pictures, and send multimedia files to the TV or projector wirelessly. In addition, DLNA has stopped updating. Now many mobile phones no longer support DLNA, which is also a big loss.

The Miracast protocol is a wireless display standard based on direct WIFI connection. Devices that support the standard can share video images wirelessly, such as mobile phones that can display a movie or photo via Miracast directly to a TELEVISION or other device without compromising the length of a connecting cable. An identical mirror feature in Miracast and Airplay puts the contents of a mobile phone’s screen directly into an HD TV screen, in the same way that you can play games and play online videos through your TV screen

Airplay Agreement

Airplay Agreement: Currently, Apple’s Airplay screen mirror is only available for certified Apple devices. Currently, this technology is supported mainly by Apple’s own devices including iPad, iPhone, AppleTV, etc., as well as some devices of Authorized partners.
After understanding the wireless screen sharing protocol, we can first learn which wireless screen sharing protocols are supported by our mobile phones, TVS and computers in the future, and then carry out the screen sharing operation.
