Description
Technical Field
The invention relates to the technical field of video conferences, in particular to an audio and video output method of a network meeting place.
Background
The network conference system integrates video communication, communication experience and conference control, and is a new video conference system in recent years. The technology has the characteristics of multipath audio and video, real person 1:1 size, listening and position distinguishing and the like, focuses on face-to-face communication effect, can provide near-eye communication remote communication experience, and is generally used for high-simulation communication requirements, such as high-end video conference application fields of remote case handling, remote consultation and the like. To distinguish between different types of venues, a conference room using this technology is commonly referred to as a web conference; the traditional conference place with single-channel audio and video stream is called a single-screen conference place.
The main video image of the network presentation system is used for transmitting real-time panoramic high-simulation video images of a conference room, and in addition, the network presentation system comprises a double-current image used for transmitting auxiliary electronic images such as documents. The sound of the network presentation system follows the main video and is output in the corresponding playing equipment to realize the function of listening and distinguishing the position.
In multiparty video conference, because of the large number of participants, the remote video can only be displayed on the local display device one by one, or after being subjected to picture composition by a platform, the remote video is displayed on a certain display device. If the method is applied to a network presentation meeting place, the characteristics of part of real people such as 1:1, listening and position recognition and the like are lost, and the images are messy, so that the meeting experience of the network presentation technology is reduced.
