DLNA, Miracast, Airplay Which projection mode is most useful? This problem is actually related to the content of the screen, the display screen and the scene of the screen.
1, DLNA protocol: only applicable to audio, video, picture push, multimedia files through the wireless way to the TV or projector above. In the process of streaming media resource screen projection, DLNA push is undoubtedly the best choice, with less consumption, stable screen projection and high fluency.
- Multi-screen interaction Miracast: The feature is that the signal end projects resources onto the large screen, and then our signal end can perform other operations without affecting the large screen.
We also use this screen projection mode a lot at ordinary times, such as the mobile screen TV, while chatting wechat, scrolling moments, while watching movies, do not interfere with each other; But it’s not appropriate in a meeting room, for example, where minutes need to be taken.
3, Airplay screen mirroring: signal end and receiving end screen synchronization
Airplay screen image mode is a mode that is widely used in meeting rooms. At present, meetings and teaching focus on the interaction between the presenter and the participant. Just imagine, the presenter in front of the big screen for a variety of sharing, operation, open the speaker mode, the signal end of the small screen will also change, after the end of the signal device can be saved with a key, isn’t it nice~
The disadvantage of the screen mirror mode is privacy. If a wechat message “your mother called you home for dinner” suddenly appears on the big screen, it will still be a little embarrassing.
