【Environmental Requirements】 Standard classrooms are sufficient.

【Advantages】

• No need for any on-site camera or broadcasting personnel, minimizing disruption to the teaching process for both students and teachers.
• Fully automated detection and screen switching by the computer system, making it the most time-efficient and labor-saving recording system.

【Disadvantages】

• Since the system relies on automatic detection, it may lead to errors in judgment if subtle movements go unnoticed or if actions do not align with the software's design logic.
• The control of camera angle switching is in the hands of the system, not the teacher, which may result in system behavior not fully meeting the teacher's expectations.
• Numerous suppliers offer such systems with varying quality, posing a higher risk in terms of effectiveness after installation.
• Complex system installation, higher budget requirements, and elevated maintenance costs.

E-Learning: Similar to an electronic whiteboard, it can project digital teaching materials onto the screen, allowing direct annotation using an interactive electronic pen, making program production easy. 【Environmental Requirements】 Four meters wide, five meters deep.

【Advantages】

• Clear and high-quality visuals.
• Only requires the preparation of teaching materials and the presence of the teacher to create instructional videos.
• Automated equipment, with simple operations by the teacher, eliminating the need for additional personnel.
• Simplified program production.
• Recording space does not need to be extensive; a three meters by five meters area is sufficient.

【Disadvantages】

• Suitable only for recording half-body-sized instructional videos of teachers.
• Requires a green background for background removal.

Multi-camera Shooting: Utilizes multiple cameras simultaneously capturing various angles, with a broadcasting machine switching between scenes based on real-time needs.

【Environmental Requirements】 According to instructional needs.

【Advantages】

• Can be filmed in any location, not necessarily in a studio.
• Convenient post-production editing for programs.
• Highest video quality comparable to television stations.
• The same equipment can be applied to other large-scale events at schools.

【Disadvantages】

• Requires a larger workforce.
• Equipment costs are relatively higher.

Virtual Studio Broadcasting System: Teachers shoot in a studio equipped with a large green screen, using background removal and virtual backgrounds/animations to create various instructional programs. Currently, this type of program production has matured, featuring simple and cost-effective equipment, delivering the best results.

【Environmental Requirements】 Single-setup: Three meters wide, six meters deep; Dual-setup: Five meters wide, eight meters deep.

【Advantages】

• Demonstrations using virtual objects or animations can make courses in subjects like mathematics, physics, and chemistry more easily understood and absorbed.
• High entertainment value in visuals, fostering increased interest in student learning.

【Disadvantages】

• Many virtual studio broadcasting systems in the market are designed for television, making background design challenging and operations complex.
• Studio and virtual studio broadcasting system equipment are relatively expensive.
• Longer program production times.
