Abstract

The invention discloses a conference system howling elimination method and device based on near field communication, which can be used in the technical field of real-time audio and video communication; the method comprises the following steps: establishing communication connection between a conference management system and clients of conference participants and between the clients; judging whether the communication connection is successfully established or not according to the communication connection between the clients, wherein if the connection fails, feeding back connection failure information to the client; if successful, determining the clients to be in the same physical space, dividing the clients accessing the conference according to physical areas to obtain a plurality of physical areas, wherein each physical area comprises one or more clients; and receiving volume information reported by the client, and traversing the volumes of all the physical areas in the conference to eliminate the howling. Herein, the probability of howling in the physical areas can be judged, and the client side with the howling phenomenon is forbidden; recognition is accurate, efficiency is high, and normal proceeding of the conference is guaranteed by eliminating howling from the source.

Description

technical field [0001] The invention relates to the technical field of real-time audio and video communication, in particular to a method and device for eliminating howling in a conference system based on near-field communication. Background technique [0002] With the development of audio and video technology, the development of conferences has changed from offline conference rooms to online conference rooms. The conference initiator invites participants online, and the participants join the virtual conference room through the terminal to participate in the conference and discuss issues. In the multi-party online audio and video conference in the prior art, there are often situations where multiple conference participants meet in the same physical space. At this time, if multiple people in the same physical space turn on the microphones and loudspeakers at the same time, howling is likely to occur, seriously affecting the experience of the participants. [0003] Generally,...
