Description

Method and terminal for processing video in video conference

Technical field

The present invention relates to the field of communications, and in particular, to a method and a terminal for processing video in a video conference.

Background technique

Video conferencing is a kind of multimedia communication technology that enables people in different places to realize "real-time, visual and interactive" through a certain transmission medium. Through various related communication transmission media, static/dynamic images, voices and characters of characters are transmitted. Multiple information such as pictures and pictures are distributed to the terminal devices of one or more users, so that geographically dispersed users can exchange information through various means such as graphics and sound, and increase the ability of multiple parties to understand the content, just like in the same Meetings are held in the venue.

With the development of video technology, users' needs are becoming more and more abundant, and video conferencing systems are required to not only provide video transmission, but also have additional functions of video conferencing systems such as electronic whiteboard, dual video technology, and remote application sharing. Better collaborate between participants. The video conferencing system will not only be used for meetings, but also become a multimedia collaboration platform.

At present, the video conferencing TV function on the market has been enriched, not only for audio and video transmission, but also for dual video streaming technology, such as H.239 and other related protocols to achieve secondary video transmission. In general, the main The video transmits the image of the person, the secondary video transmits the content that needs to be shared, and some manufacturers have implemented the multi-secondary video function, that is, the multi-party is allowed to simultaneously transmit the auxiliary video on the same video conference. In addition, the types of terminals that are called are also very rich. In addition to the conference television equipment, you can also call mobile communication devices such as mobile phones, pad (tablet), and Skype (Xunjiapu).

The so-called dual-stream as the name suggests is: The terminal can send/receive two video streams at the same time, so that only by sharing the network bandwidth can the user get more information, no more resources, and more information at a minimum cost.

When the video conference is in progress, it is inevitable to interact with the participants, and the interactive control between multiple screens. When the current conference TV is in the conference, each participant is passive and can only receive The video screen cannot operate on the screen, lacking the real venue concept.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other without conflict.

FIG. 1 is a flowchart of a method for processing a video in a video conference according to an embodiment of the present invention. As shown in FIG. 1 , the method in this embodiment includes:

511. In the video conference, transmitting the secondary video to each participant terminal;

512. Receive an operation event that is sent by any one of the participant terminals to the secondary video.

513. Process the secondary video according to the operation event.

S14. The processed secondary video is transmitted to each participating terminal.

The secondary video includes: an application screen and/or a remote desktop.

In this embodiment, one of the participants is the output side of the video source, and the dual-stream mode is used to implement the secondary video preview of the conference party. Each party can see the video source image and achieve the multi-party video effect. a communication channel is established between the participants and the video source output party, and when each party operates, an operation event (such as a mouse click event, etc.) is sent to the output side of the video source through the established channel, and the video After receiving the event information, the output party of the source performs corresponding operations on the broadcasted video, and synchronizes the video to each party of the conference; thereby achieving the effect of interaction between the multiple screens, and achieving the interactive operation effect of the participants on the video.
