Mainly targeting K12, language training, vocational education, well-rounded education and other fields, for large online class classes, open classes live streaming:

  • One-way live streaming of teaching, students’ concurrent viewing is not limited, providing a smooth teaching experience.
  • Students may raise their hands to initiate 1v1 or 1vX interactive stream connection with the teacher.
  • The rest of the students keep watching the interaction between the teacher and the student connected to the stream
  • The role of “teaching assistant” can be adopted to help manage the classroom.
  • At the end of the class, users may replay the recorded content and view any stored teaching content.

Mainly targeting K12, language training, for 1v1 tutoring classes, or small classes with a small number of students:

  • All the members of the class are live streaming by default, and the students and teachers speak and communicate on the stream automatically.
  • Supports up to 12 students for real-time audio and video interaction with teachers.
  • The role of “supervisor" can be adopted to provide supervision on learning results and teaching quality without interrupting the class.
  • A small class featuring multi-person real-time audio and video interaction with enterprise video conferencing in mind.
  • Large class setups are suitable for enterprises with significant amount of remotely distributed employees and require cross-regional training interaction.
  • Diverse streaming classroom functions such as roll call, document sharing, interactive whiteboard, banning and removal to enrich the effect of conference discussion and online training.
