Technical field
The present invention relates to AV device technical field, specially a kind of AV device of long-distance education.
Background technique
Study is one of significant process of human progress, and in order to turn out more outstanding students, teacher is to student's
Education is also to play the role of vital, and education can make student establish correct concept, study to more useful
Knowledge, allow student can preferably be in the future society, be that motherland contributes.
Attention with society to education, more and more students learn on the classroom that teacher personally instructs incessantly, also
Some non-long-distance video classes personally instructed can be found and further learnt and supplemented knowledge, but be that typically in student viewing and remotely regard
When frequency course, interaction is lacked between the teacher in student and long-distance video, only student unilaterally receives, and it is more dry as dust,
Teaching efficiency is poor.
In the prior art, when one classroom viewing long-distance video course of students oligomerisation, in order to keep student remote in viewing
It can be interacted with the teacher of the video other end when journey video classes, be equipped with an interactive audio frequency acquisition for each student and set
It is standby, it is interacted so that each student can engage in the dialogue with the teacher of the other end, but this interactive audio frequency that is equipped with one by one is adopted
Collect the mode of equipment, on the one hand, more interactive audio frequency acquisition device configuration meeting waste of resource causes unnecessary economy to open
Pin；On the other hand, every student is each equipped with interactive audio frequency acquisition equipment, and can to engage in the dialogue with teacher when interacting generates people
More mouthfuls of miscellaneous phenomenons, it has not been convenient to the management of teacher, and then decline classroom efficiency.
