Embodiment Construction
[0046] The technical solutions provided by the following embodiments of the present invention are applicable to a multi-screen video communication system. When conducting a multi-screen video conference, multiple conference sites may be included, wherein there may be at least two cameras in one conference site of the video communication system , at least two monitors, and at least two participant areas. The terminal in the venue compresses and encodes the image signal captured by the camera and the voice signal of the participant picked up by the microphone in the participant area, and transmits it to the remote venue through the transmission network, so as to realize Communication between two sites or multiple sites.
[0047] During the image switching process in a multi-screen video conference, certain switching principles need to be met. The following takes a three-screen conference site as an example to illustrate in detail. Assume that there are two three-screen conference...

The invention provides a method and a device for controlling display positions of images of conventioneers in a multi-screen video conference. The method comprises the following steps: receiving an image switching command, wherein the command designates a first screen in a second meeting place to display a conventioneer in a first meeting place which is to be displayed; judging whether an arrangement sequence of an image of the conventioneer to be displayed which is displayed on the first screen in the second meeting place and an image of a conventioneer which is displayed on the second screen is the same as a position sequence of the conventioneer displayed on the first screen and the conventioneer displayed on the second screen in the first meeting place; if yes, then determining that the first screen in the second meeting place to display the conventioneer to be displayed; and if no, then adjusting the sequence of the image of the conventioneer which is displayed on the first screen in the second meeting place and the image of the conventioneer which is displayed on the second screen in the second meeting place. By adopting the technical scheme, a conventioneer to be displayed can be displayed on a screen in a target meeting place.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for controlling the display position of a participant's image in a multi-screen video conference. Background technique [0002] The video conferencing service is a multimedia communication service, which uses a video terminal and a communication network to hold a meeting, and can simultaneously realize the interaction of images, voice, and data between two or more locations. The terminal in the venue compresses and codes the image signal captured by the local camera and the voice signal of the participant picked up by the microphone in the participant area, and transmits it to the remote venue through the transmission network. At the same time, the digital signal from the remote venue is received through the transmission network, and the digital signal is decoded to obtain the images and signals of the participants in the remote venue. With the develop...
