One of the scenes: campus meeting Digital audio and video broadcast

School leaders, teachers, students can be in different locations to complete the audio and video broadcast meetings.

Scenario two: Hearing test

Traditionally the school to organize students to foreign language class hearing test, the examination, the teacher will generally arrange for each class to read, explain,

For the same grade school more schools, limited to limited resources of teachers, it is difficult to arrange hearing tests, examinations, and arrangements for different divisions

Help, vary the rhythm of pronunciation, pronunciation is also clear, will affect the hearing test, examination fairness.

Playing the recording method because of its poor flexibility, pre-work cumbersome, error-prone, the students also hear the sound but not the person, and bear

Invisible pressure, because this way also suffer from the school, teachers, classmates criticized.

Futaier network audio and video broadcasting system The use of powerful audio and video processing capabilities, leveraging the power of the network, successfully resolved

The Schools, teachers, classmates of the trouble.More use of its available, multi-tasking a total of the advantages of management, in the same system,

So that different grades (each grade may be a number of classes), while hearing tests, examinations, examiners do not necessarily pro

Pro examination room, just in any campus network nodes (such as teaching and research, conference rooms, offices, etc.), can host the hearing test,

While the students listen to the same time teachers can also see the kind of video images.

For a full network upload bandwidth between the inter-school, you can also organize a unified hearing test, examination.
