1. Video ability: In the double-teacher live course, rich interactive presentation methods in the classroom need corresponding scene support, such as: art calligraphy customers need to show detailed actions, and the interactive answering process needs to see the performance of teachers and classmates at the same time.
However, in some solutions, video conference manufacturers only have the ability of audio-video interaction, and need more complicated solutions or physical connections to realize functions such as picture synthesis; The video display mode of live broadcast software manufacturers is relatively simple, and they can only display videos and PPT pictures, and only apply live broadcast scenes to classrooms, which cannot meet the requirements of double-teacher scenes in terms of picture effect, resolution and frame number.
Baijiayun Double-teacher classroom has completely independent research and development ability in audio and video, and can show different video confluence through the software of the double-teacher, which can be applied to multiple scenes. In addition, Baijiayun can provide ultra-high-definition audio and video transmission at 4K and 60FPS without delay, which can fully prepare for future audio and video extension in the long run.
2. Teaching interaction form: The novel interaction form of double-teacher class is the main reason why parents choose to take double-teacher class at present. At the same time, by collecting and analyzing students' classroom data, we can quickly find students' problems and effectively track students' learning effects.
At present, the double-teacher classroom answering system provided by Baijiayun, including ordinary answering machine, voice answering machine, dot-matrix pen answering system and other functions, can improve interaction and record students' learning data completely. However, some video conferencing and live broadcast software cannot complete such scene applications, and the double-teacher classroom without data and interaction is less attractive, which will naturally affect its learning effect.
3. Customized development docking: For institutions, the deep development docking ability of products is an important indicator of future sustainable development. Double-qualified classrooms must have sustainable research and development capabilities to meet the continuous technological changes.
These capabilities include: the combination of AR, VR and AI can realize the integration and docking of internal systems of institutions; Integration and docking of business systems such as course arrangement, course cancellation and registration system; Online school, membership system, student evaluation system, etc.
In video conferencing or live broadcast solutions, most vendors' SDK and API are complex, not open enough, or do not support docking. Baijiayun has a completely independent research and development of audio and video bottom layer and dual-teacher interactive system, providing various interfaces for docking. As a business department, the double-teacher department operates independently, and will continue to explore and develop the double-teacher scene and explore the double-teacher model for a long time.
4. Perfection of hardware scheme: The hardware scheme of double-qualified teachers must be verified by the actual teaching scene. Due to the diversity and complexity of the actual classroom scene, it is necessary to adjust the sound field, lighting, network and other conditions according to the actual situation. If there is only one omni-directional microphone in the classroom, some students' voices will not be received, which will create a form of false interaction, and the teaching effect needs to be verified.
Many video conference and live broadcast manufacturers have pieced together a dual-teacher scheme by saving their own hardware. Without large-scale actual verification, there will be problems such as microphone howling, unclear camera, poor screen display and poor experience, which naturally cannot win the trust of students and parents.
Baijiayun provides a complete set of software and hardware solutions and deploys 4,000 classrooms across the country. The hardware solution has been verified in practice. Its unique classroom dual microphone design solves the problem of receiving sound from students at the edge. The hardware has been specially designed, and there will be no problems such as howling, noise and echo, and the received sound will be clearer and the interaction will not be delayed.
5. Planned deployment capability: The deployment capability of the dual-division plan is also an important consideration. Standard deployment scheme helps to ensure rapid and large-scale deployment, and vendors with rapid and large-scale deployment capabilities can provide better after-sales service, rapid response and problem solving.
Video conference manufacturers are mostly agent cooperation mode, and the deployment and installation are mostly provided by local agents, and the standards are not uniform. The live broadcast software solution has no hardware solution support and basically has no deployment capability.
Baijiayun Shuangshi completed the deployment and installation of 300 classrooms in a single month, with uniform deployment standards and well-documented standards such as acceptance training. It not only completes the deployment task with high quality, but also provides valuable time for customers to start classes quickly.
The choice of double-qualified classroom suppliers must be considered from a long-term perspective. First of all, after a long period of accumulation and adjustment, dual-qualification business must be the goal of the company's strategic planning; Secondly, the dual-teacher manufacturer must be a manufacturer specializing in the research and development of the dual-teacher system platform, which requires a high degree of cooperation. It can provide different service capabilities according to the business needs at different stages, including but not limited to: enterprise R&D capabilities, enterprise life span, dual-teacher implementation capabilities, and so on. The dual-teacher system should not only solve the problem of audio-video interaction, but also have a complete system.
Baijiayun Double Teacher Classroom is a one-stop double teacher classroom solution provider focusing on the education industry. It has helped hundreds of educational institutions and public schools to successfully carry out dual-teacher teaching, and deployed more than 4,000 dual-teacher classrooms across the country, covering all provinces and regions in Chinese mainland except Hong Kong, Macao and Taiwan. Baijiayun Double-Teacher Classroom has specially built a double-teacher live broadcast system, a double-teacher interactive system and a double-teacher operation management system for the double-teacher teaching scene, and on this basis, it has derived an ecological service platform around the double-teacher business, providing services such as community marketing acquisition tools, double-teacher live broadcast room rental, double-teacher classroom decoration scheme consultation, double-teacher operation consultation and double-teacher course content docking.
