How does the video booth access the smart classroom? Connection scheme and acceptance list

From video booths, interactive whiteboards to teaching computers, analyze how Qtenboard can use MT9679/RK3588 multi-platform chip configuration and complete interface support to help schools and system integrators sort out connection methods, functional boundaries and project acceptance points.

October 2026Qtenboard Integration GuideApproximately 14 minutes to read

Connecting online does not mean completing the integration. The equipment should cooperate to complete the teaching task, not just the picture display. The booth has pictures, but the whiteboard touch cannot operate the teaching computer. Teachers can display paper materials, but they cannot annotate or save them on the screen. The booth can be connected to the interactive whiteboard, but the operation of switching the signal source does not conform to the classroom habits. The solution is available in the demo environment, and there is a compatibility problem after connecting to the school network or existing computer.

Smart classroom integration should be designed according to the teacher's teaching process: display physical or paper materials, enlarge details, annotate, save or share. Each step should correspond to the equipment, interface and software, not just "screen can be displayed" as the acceptance criteria.

Qtenboard (Shenzhen Qunmao)Founded in 2005, we have been dedicated to interactive display manufacturing for 20 years. We operate a 330,000㎡ smart manufacturing industrial park in Shenzhen and Guangzhou, comprising 16 factory buildings and 8 fully automated production lines, with a daily output capacity of 200 units, serving customers in 120 countries and regions worldwide. The Qtenboard interactive whiteboard covers 55-110 inch full-size segments, is equipped with Q AI system-level framework and DMS equipment management system, supports MT9679/RK3588 multi-platform chip configuration, and is equipped with a video booth product portfolio, providing a complete scheme from interface adaptation to batch delivery for smart classroom integration.

What are the 1. three types of equipment?

Divide functions first, then discuss wiring

The video booth, interactive whiteboard and teaching computer in the smart classroom perform their respective duties. Understanding their division of labor is the premise of designing the connection scheme.

Video boothResponsible for shooting and displaying paper materials, physical objects or demonstration objects. The output mode, resolution, zoom capability, lighting conditions, microphone configuration and supporting software shall be confirmed at the time of purchase. Qtenboard supporting video booth supports HDMI and USB output.

Interactive WhiteboardResponsible for display content, touch operation, writing and annotation. Input interfaces, touch links, software functions and signal switching methods need to be confirmed during procurement. The Qtenboard interactive whiteboard covers 55-110 inches and supports HDMI video input and USB touch return.

Teaching computerResponsible for running courseware, instructional software and content management programs. When purchasing, you need to confirm the operating system, interface type, driver compatibility, network conditions and rights management. The Qtenboard Windows OPS is based on the MT9679 or RK3588 platform and supports switching with Android systems.

2. two common access schemes

Select Direct or Computer Transit based on teacher workflow

The core basis of scheme selection is the teacher's workflow. If only simple physical display is required, priority will be given to evaluating the directly connected whiteboard of the booth. If software processing, recording or courseware insertion is required, priority will be given to evaluating the access of the booth through the teaching computer. If you need the teacher to control the computer from the whiteboard, you must verify that both the video and touch connections are configured.

How to check the 3. interface and equipment list.

Inspect separately by signal, control and power supply

Video signal.Confirm the booth output interface, Qtenboard whiteboard input interface (HDMI), resolution and refresh rate compatibility requirements, cable length and wiring method, and whether a switcher or extension device is required.

USB and control.Confirm whether USB connection is used for video, control, touch control or equipment power supply; Whether the booth needs drivers or software; Qtenboard the way whiteboard touch is transmitted back to the teaching computer; Whether the power supply capability of USB interface meets the requirements of peripherals.

Power and audio.Confirm whether the booth needs independent power supply; whether the microphone or audio should be connected to the classroom audio; whether the cable can be fixed, marked and easy to maintain; Qtenboard the startup sequence of whiteboard, teaching computer and booth.

In actual projects, it is recommended that integrators submit a complete signal path diagram before wiring, indicating the direction of video, USB data, touch return, audio and power supply. This drawing can not only help on-site construction, but also quickly locate the problem link during subsequent troubleshooting.

How 4. Complete Smart Classroom End-to-End Testing

Use a complete teaching process to check whether the equipment is really coordinated.

It is recommended to set up the following test tasks and perform them sequentially:

1. Launch Qtenboard whiteboards, instructional computers and booths
2. Display books, laboratory materials, or physical objects.
3. Zoom in, focus, and adjust the light
4. Switch the booth screen to a Qtenboard whiteboard or a teaching computer
5. Use Qtenboard whiteboard touch to annotate
6. Save or intercept class content (Q AI supports handwriting recognition and summarization)
7. Switch back to courseware or instructional software
8. If there is recording or distance teaching, verify the audio and video and sharing
9. Confirm file save location and user exit process after completion

The acceptance record shall include: equipment model and software version, interfaces and wires used, operating system and application version, whether each task is passed, error prompt and repetition steps in case of failure, problem rectification and retest results.

5. common problems and troubleshooting framework

Locate signal, control, software or power problems first

The whiteboard has no booth screen.Check input source, cable, booth output and whiteboard input first. Check whether the HDMI input source is switched correctly.

There is a display, but it is not touch-sensitive.Confirm whether a separate touch return or computer connection is required. Check the USB touch backhaul configuration.

The computer cannot find the booth.Check the USB connection, drivers, operating system, and application permissions. Confirm Windows OPS driver compatibility.

The picture is blurred or the delay is obvious.Check focus, resolution, connection, and computer performance. Qtenboard supports 4K UHD display, and the RK3588 platform supports 8K decoding.

The booth screen cannot be annotated or saved.Check the whiteboard software, current source and save function. The Q AI supports handwriting recognition and content saving.

Audio does not go into classroom acoustics.Check the booth, computer, whiteboard, and external audio paths. Confirm the audio interface configuration.

The switching process is complex.Inspect the signal source layout, equipment startup sequence, and control scheme. Qtenboard supports multi-source signal management.
