With the improvement of teaching reform and teaching needs, the single touch function of touch screen can not meet the actual requirements of teaching, such as wireless screen casting, multi screen synchronization, real-time broadcasting, any screen control, any personnel screen casting and other functions begin to be applied to the current multimedia classroom.

Requirements: 1 teacher main screen + 4 student group screens, a total of 5 touch screens need to be displayed synchronously, and the teacher can operate on the main screen, and then carry out multi screen teaching.

The actual deployment process of Bijie multi screen collaboration 

1. The 5 display screens need a BiJie multi screen collaboration device, and then connect the BiJie multi screen collaboration device with the large display screen by HDMI cable.
2. Network cable deployment: because the classroom was designed with a network cable interface reserved on the side of the large screen, the wireless projector was directly connected with the network cable.
3. 5 sets of wireless projectors for one host and multicast settings.

1. Multi screen interaction

Teachers can operate all the display screens, teachers can use computers, mobile phones connected to the main screen. It can realize the touch feedback function, that is, the handwriting and annotation of the teacher’s touch screen will be sent back to the computer, and the computer screen will be controlled reversely.

2. Multi screen simultaneous display
The teacher screen and each group screen display the same content synchronously.

3. Host mode
Teachers can directly operate the up screen, down screen and full screen on the big screen or their own computer or mobile phone.

4. Multi screen display
Teachers can only display the screen of students, generally put four student screens on five display screens for comparison.

5. The students cast the screen on the secondary screen independently
Students can cast the screen to the display screen of the assignment group.
