Screencasting is a question often asked by novice players, so what are our commonly used frequency casting methods? How does it work?
First of all, we need to understand two concepts, the first is the same screen, and the second is the projection screen.
Same screen: As the name implies, the content on the terminal device such as the mobile phone screen is completely synchronized to the display device. Here we only talk about professional home theater projection. (Simple display device without system)
After the above description, we know that screen projection must be realized from the playback source. The method is to install the same screen software on the mobile phone and the box or the player under the same local area network, and open the software. The software connected to the box can display the screen of the mobile phone through the box to make the projection present, but the point is this, the presentation is presented, and even sliding down the screen of the mobile phone is not smooth, do you think you can still play video? So it's not realistic for you to use it.
Next, let's introduce mobile phone screen projection.
Screencasting: It refers to casting the specified video on your mobile phone without preventing your mobile phone from doing other things. For example, if you use your mobile phone to cast a movie, then while watching the movie on the big screen, you can still chat with Q, browse the circle of friends, and play mobile games. There is no mutual influence between the mobile phone and the projector.
So how to achieve it? In fact, it is the screencasting software that comes with your box or a third-party DLNA protocol. If you want to cast a video on iQIYI, then click the video on iQIYI, and then click the bottom right corner. There is a screen cast to TV or a screen cast assistant similar to click it, find your box, click connect, and then the box will receive this command, and then search to release the video. Then it has nothing to do with the mobile phone, the mobile phone can be turned off, so there is no transmission between the mobile phone and the box, this is directly released by your box, and there will be no other problems.
One point to mention: In fact, these video software can be installed on the box, and our screen projection is only used to solve the problem of membership. (The member on the box is the TV version and the mobile phone member is different)
