Embodiment 1

[0112]Step 20: Determine the location coordinates of the first specified user in the venue.

[0113] In the embodiment of the present invention, there are many ways to determine the position coordinates of the first designated user in the conference venue. Preferably, the position coordinates of the first designated user in the conference venue are determined by using the audio-visual position identification technology, for example, through the The sound signal collectors set at different positions acquire the sound signals of the meeting place, and calculate the spatial position of the signal source that sends out the sound signal according to the collected sound signal with the highest intensity; or, determine the first specified position through the position locator Positioning of the user's position coordinates in the venue by using a position locator is a relatively mature technology in the prior art, and will not be described in detail here.

Embodiment 2

[0121] Step 200: Receive video image signals of the first designated user and video data signals of conference materials sent by other conference sites.

[0122] Step 210: Combining the received video image signal of the first specified user and the video data signal of the meeting material into one video coded signal.

[0123] Step 220: Decode the synthesized coded video signal, and display it on the same display screen in the venue.

[0124] In the embodiment of the present invention, when receiving video image signals of the first designated user from other conference sites, video images of multiple second designated users in the same conference site as the first designated user from other conference sites may also be received. Image signal, there are many ways to process the received video image signals of a plurality of second specified users. Preferably, the received video image signals of the first specified user and the video image signals of the second specified user ...

Embodiment 3

[0128] Step 2000: Obtain a coded video signal that synthesizes the video image signal of the first specified user and the video data signal of the conference material.

[0129] In the embodiment of the present invention, the obtained synthesized video coded signal may include not only the video image signal of the first designated user, but also the video image signal of at least one second designated user.

[0130] Step 2100: Decode the obtained coded video signal, and virtually cut any display screen in the venue into a preset number of sub-display screens.

[0131] Step 2200: Display the decoded video image of the conference material on the above at least one cutout sub-display screen, and display the decoded video image of the first specified user on the other at least one cutout sub-display screen show.

[0132] In the embodiment of the present invention, the obtained synthesized video coded signal may not only include the video image signal of the first specified user, ...

Abstract

The invention relates to the technical field of video communication, and discloses a method and a device for displaying conference materials in a video conference. The method comprises the following steps: the position coordinates of a first specified user in a conference hall are determined; a video image signal of the conference hall is acquired, and the video image signal of the conference hall is cut according to the position coordinates to acquire a video image signal of the first specified user; and a video data signal of displayed conference material is acquired, the video image signal of the first specified user and the video data signal of the conference material are synthesized into one video encoding signal, and the video encoding signal is sent to other conference halls for signal decoding and is displayed on the same display screen of other conference halls. Thus, the video image signal of the first specified user and the video data signal of the conference material are presented on the same display screen in the form of one video encoding signal, so that the problem that a video conference system in the prior art is hard to move, poor in flexibility, high in maintenance cost and low in conference efficiency is effectively solved.

Description

technical field [0001] The invention relates to the technical field of video communication, in particular to a method and device for displaying conference materials in a video conference. Background technique [0002] With the development of video coding and network technology, the application of network video is becoming more and more extensive. One of the application methods of network video is video conferencing. Video conferencing technology is to collect and digitize the on-site information of the party participating in the communication with video and audio acquisition equipment, and then perform corresponding compression processing, and then transmit the digital signal to the remote end through the available communication channel / line for decompression, Restoration and reproduction technology, that is, video conferencing is a meeting that integrates video, audio, and data communication. It can transmit images and sounds of each venue in real time, so that each venue i...
