Screen mirroring is a very practical function used in teaching. Teachers can directly use the touch screen to reverse the operation of the screen mirroring on their mobile phone or computer during teaching, such as flipping through PPT pages, fast forward and rewind, and so on.

4. Multi machine linkage

The multi machine linkage function is mainly used for group discussion classrooms. This function mainly realizes the interaction between the classroom main screen and the group screen through the multi machine linkage function. The multi machine linkage function can broadcast the teacher’s main screen image to the group screen for simultaneous display with one click, or drag and drop the group screen image to the classroom main screen for display or distribution, making it convenient for the teaching teacher to share, review, and compare courseware.

(1) Main device broadcast:

① Click the “Broadcast” button to synchronously broadcast the screen projection content of the main device to all group screens. During the broadcast process, the screen images of the group screens and the main device remain synchronized and displayed.
② Click ‘Close Broadcast’ to disable the broadcast function.

(2) From device display:

① Click on Group Screen A in any “Group Signal Source” and drag its content to the “Main Device” large screen for display.
② When the screen of Group A is in the display state of the “main device” large screen, click the “broadcast” button of the “main device” to broadcast the screen of Group A to the large screens of Group B, Group C, and other groups.

5. Interactive Touch Control

For different smart classroom display environments, Bijie Multimedia Collaboration System provides various interactive operation solutions, whether it is a non OPS touch all-in-one machine, OPS touch all-in-one machine, or a regular TV/projector, it can provide adaptive linkage solutions.
  • Supporting non OPS touch all-in-one machine
Non OPS touch all-in-one machine refers to a large screen that only provides display and touch functions. Users only need to use HDMI video cable and USB touch cable to connect the Bijie multimedia collaboration system with the touch screen, and can perform screen interaction operations and terminal configuration management on the touch screen.

The Bijie Multimedia Collaboration System has a sidebar control function. Clicking on the function buttons in the red area on the large screen allows for interactive operations and configuration changes on the multi screen collaboration terminal.

  • Supporting OPS touch all-in-one machine

OPS all-in-one machines generally use the Windows system as the main system. During the teaching process, the frequency of using Windows teaching software in the classroom is very high. The video output of the Bijie Multimedia Collaboration System is an independent signal source, and the OPS all-in-one machine needs to be switched to HDMI display mode, which brings the problem of teachers needing to frequently switch signal sources. In response to this issue, Bijie Internet specifically provides Windows based control interaction software and control API interfaces.

Install interactive management software on the Windows side, using a floating window form, providing one click broadcasting, same screen content display, and screen projection device configuration functions;

The Bijie multimedia collaboration system and OPS touch all-in-one machine only require one data cable connection.
