Remote interaction method and system

Abstract

The invention relates to a remote interaction method and system. The remote interaction method comprises first-level audio collection, second-level audio collection and third-level audio collection. The first-level audio collection comprises collection of first audio information and collection of second audio information; the second-level audio collection comprises the step of collecting audio information collected by the first-level audio collection, and the audio information is local audio information; the third-level audio collection comprises the step of collecting audio information sent by a far end; the first audio information and the second audio information acquired by the secondary audio acquisition are not played locally; the third-level audio collects the collected audio frequency information to carry out local audio frequency playing; the second-level audio collection performs mutual exclusion collection on the first audio information and the second audio information at thesame time; and after echo cancellation is carried out on part or all of the first-level audio information collected by the second-level audio collection, the first-level audio information is sent toa far end. Compared with the prior art, the audio quality in the remote audio interaction process can be effectively ensured, and a better audio playing effect is achieved.

Description

technical field [0001] The invention relates to the field of remote interaction, in particular to a remote interaction method and system requiring remote interaction such as teaching and conferences. Background technique [0002] The traditional on-site teaching method, because students can directly face the teacher, the classroom atmosphere is most likely to be driven by the teaching teacher, and can have more interactions. Therefore, the traditional on-site teaching method has always been the most popular, teaching The most effective way of teaching. With the development of the information age, the development of the Internet and the shortage of effective teaching resources, limited by space and time, only the traditional teaching method can no longer meet people's learning needs. A considerable number of learners study through the Internet. The method can be recorded video or remote online education, but both the recorded video and remote online education have the intera...

Problems solved by technology

However, in the interaction, when the sound of the questions answered by the local students is picked up by the far-field microphone and transmitted to the remote classroom, since the sound transmitted to the remote classroom will be amplified by the power amplifier at the far end, the amplified sound will be heard in the remote classroom. The omnidirectional microphone in the end classroom is collected back, which leads to problems such as echo, the audio playback effect is poor, and the interactive audio experience is effective
