Problems solved by technology

This will bring about a problem: when the camera lens is turned, the speaker directly in front of the strip device is next to the screen, or even not within the screen, but the sound orientation information collected is still directly in front, which leads to The position of the speaker does not match the collected orientation information
[0005] Therefore, it is necessary to provide a method to solve the problem that the position of the speaker in the picture does not match the collected sound orientation information when the camera lens is rotated in the above patent

Embodiment Construction

[0050] Figure 1A is a schematic diagram of a video communication system, in which 110 is a site at the sending end, 111 is a site at the receiving end, and 109 is a communication network, which may be an IP network, a PSTN network, or a wireless network. In the venue 110, 101 is a camera, 102 is a video communication terminal, 103 is a TV, 104 and 105 are participants, and 112 and 113 are speakers. There are multiple microphones in the venue 110. The microphones can be placed inside the terminal 102 or inside the camera 101, or independently placed outside, connected to the terminal 102 through a transmission line, or both inside and outside. In the venue 111, 106 is a camera, 107 is a video communication terminal, 108 is a television, 104a and 105a are images of participants 104 and 105, and 114 and 115 are speakers. There are multiple microphones in the venue 111. The microphones can be placed inside the terminal 107 or inside the camera 106, or independently placed outside...

Abstract

This invention discloses a video communication system with sound position information including multiple microphones used in collecting multiple sounds, a camera head receiving control orders to rotate or regulate focus and a processor connected with the camera head and multiple microphones, in which, the processor computes the position information of the sound source based on the phones collected by the microphones and regulates the position information of the source based on the control information of the camera head, which solves the problem of non-match of the speaker position and the collected sound orientation information.

Description

technical field [0001] The invention relates to the technical field of video communication, in particular to a video communication system with sound position information. Background technique [0002] At present, the screens of TVs are getting bigger and bigger. In addition, some video communication systems use projectors or video wall displays, which cause the participants to move a lot on the screen. However, the sound of the current multimedia communication system does not follow the speakers The location changes, i.e. the sound has no bearing information, resulting in a lack of realism in the video communication. [0003] In U.S. Patent Publication No. 20030048353, a method for solving the above-mentioned problems is disclosed. The specific solution is: place a strip-shaped device on the top of the TV set, in which there are multiple microphones, multiple speakers, and camera. After the sound signals collected by the multiple microphones are processed, a voice signal a...
