[0004] At present, users mostly judge which video display window the audio played corresponds to, that is, who is speaking, through sound characteristics (such as sound thickness, pitch, etc.), or by observing the mouth shape of participants in each video window. Doesn't have the presence of a live meeting
[0005] In addition, when multiple participants speak at the same time, the speaker will play the audio of multiple participants at the same time, which will also cause sound confusion, which not only affects the quality of the call, but also makes it more difficult for the user to identify which video display the sound corresponds to. window, i.e. it is more difficult to determine who is speaking

Embodiment Construction
[0037] The sound processing method of the video conference according to the present invention will be described in detail below with reference to the accompanying drawings. Such as figure 1 Shown, the method for automatically controlling video volume of the present invention comprises steps:
[0038] Step S10: Determine where each video display window in the display terminal is located on the screen.
[0039] Such as figure 2 As shown, in the first embodiment of the present invention, the video display terminal includes three video display windows: left, center and right. The four endpoint coordinates of the video display terminal screen are (0,0), (X,0), (X,Y) and (0,Y) respectively. Take the midpoint An of the abscissa where each video display window is located, where n is the serial number of the video display window. Then, the position of the video display window relative to the video display terminal is represented by the expression An / X.
[0040] It is not difficul...

The invention provides a sound processing method for a video meeting. The method is characterized by comprising the following steps of A, determining the position of each video window in a video display terminal of the video meeting; B, according to different positions of each video display window, configuring a sound field corresponding to each video display window for each video display window; and C, playing audio data according to the configured sound field corresponding to each video display window when the audio data corresponding to each video display window is played. The video display window corresponding to a direction is determined through the direction corresponding to the played sound, so that a meeting partner who makes a speech is determined.
Description
technical field [0001] The invention relates to the technical field of video conferencing, in particular to a sound processing method for video conferencing. Background technique [0002] For the current video conferencing (including multi-person video conversations of instant messaging such as QQ, MSN, etc.) system terminals usually include a display terminal composed of a large-screen display, a projector, a video wall, etc., and speakers arranged on both sides of the display terminal, Microphone, and a host for audio and video transmission. Wherein the host can be implemented by a computer. [0003] When a user conducts a video conference with multiple conference participants, the host computer receives the audio and video data of each conference participant from the network, and the display terminal displays the corresponding video in each video display window of each conference participant, and plays the received video through the speaker. audio. [0004] At present,...
