airplay is a wireless technology developed by apple. It is mainly used to support IOS devices, including iPhone, iPad and MacBook. Pictures, audio and video are transmitted to display devices that support airplay through WiFi. IOS devices basically support this function without installing any additional software, which is more convenient.
DLNA was initiated and established by Sony, Intel, Microsoft, etc. DLNA has similar functions and protocols with airplay. They can put the media content in your mobile phone into the TV screen. The difference is that DLNA on the mobile phone does not have the image function similar to AppleTV’s airplay, nor does it have the dual screen game experience supported by AppleTV. At present, DLNA can only send photos and videos of mobile phones to the large screen.
miracast is a wireless display standard based on Wi Fi direct connection, which was formulated by the Wi Fi alliance in 2012. Devices that support this standard can share video images wirelessly. For example, mobile phones can use miracast to send movies or photos directly to TV or other devices. Unlike DLNA, miracast also has a mirror function similar to airplay, which can directly put the screen content in the mobile phone into the HD TV screen, so that you can play games through the TV screen. At present, mainstream Android phones support it.
4. Widi screen projection
widi is the built-in wireless screen projection display function of windows10 computer (not necessarily supported by the rear WiFi network card). It is improved based on the miracast protocol. Win10 users can easily display on the same screen wirelessly. Personally, I think this is the most convenient way of computer screen projection at present.
5. Google cast
supports image projection or Chrome browser launch projection. When using Bijie conference box for wireless projection, Google mobile terminal can use image projection function, and mobile terminals of other systems can use Chrome browser to launch projection.
6. Bjcast (software / hardware)
bjcast is a screen projection protocol independently developed by Bijie. Any version of windows system, Android system, IOS system and Mac computer supports the installation of Bijie screen projection software or key transmitter equipped with bjcast protocol, and use bjcast protocol for screen projection.
