Embodiment 1

[0025] The embodiment of the present invention provides a sub-picture video source selection method in a multi-picture, the method reasonably selects the video source of the sub-picture according to the video status of each video source connected in the conference, thereby improving the correctness and accuracy of the system user experience.

[0026] figure 1 It is a flowchart of a method for selecting a video source of a sub-picture of a multi-picture in a multimedia conference according to an embodiment of the present invention, such as figure 1 As shown, the method includes:

[0027] Step S102, the multi-point control unit detects whether the state of the video source of each sub-picture of the multi-picture is abnormal;

[0028] In step S104, the multipoint control unit selects a video source whose status is normal as a video source of the sub-picture corresponding to the video source whose status is abnormal.

[0029] In this embodiment, the multi-point control unit de...

Embodiment 2

[0036] The purpose of this embodiment is to propose a flexible and feasible multi-picture sub-picture video source selection method, which can reasonably select the sub-picture video source according to the access video source status of each terminal in the conference, effectively solving the problem of During the multi-screen conference, the sub-screen has no image caused by the problem of the video input source, which improves the user's video experience and conference quality. The method described in this embodiment relates to the technical field of multimedia conferencing, and is a method for selecting sub-picture video sources of multiple pictures in a multi-point control unit system.

[0037] The implementation process of this embodiment will be specifically described below in conjunction with the accompanying drawings.

[0038] figure 2 is a structural block diagram of a multi-point control unit according to an embodiment of the present invention, wherein the dotted l...

Embodiment 3

[0066] This embodiment is a further optimization of Embodiment 1, and the implementation process of this embodiment will be described below.

[0067] Assume that the number of multi-screens in the conference is P, and the number of terminals in the conference is T, where T is greater than P. In the initial stage, there is no terminal access, the number of videos detected by the detection unit, the video source state list and the sub-picture state list of the control unit are all empty.

[0068] The T terminals go up one by one. When the Tt-th terminal goes up (Tt is less than P), the video source St of the Tt-th terminal is input to the access unit. At this time, the detection unit reports that the status of the new access video source St is normal. ; When the reported message arrives at the control unit, the control unit adds an entry Lt in the video source status list, and selects an idle sub-picture Pt in the sub-picture status list, and then the control unit commands the s...

Abstract

The invention discloses a selection method and device for a video source of a sub-picture of a multi-picture in a multimedia conference. The method comprises the following steps that: a multi point control unit detects if the state of the video source of each sub-picture of the multi-picture is abnormal; and the multi-point control unit selects the video source in a normal state as a video source of the sub-picture corresponding to the video source in an abnormal state. The invention solves the problem that the input fault of a terminal video or no video input affects the conference quality of the video conference in correlation techniques, and achieves the effect of normal image display for the sub-pictures of the multi-picture.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for selecting a video source of a sub-picture of a multi-picture in a multimedia conference. Background technique [0002] In the existing video conference system, users can see the images of other online users in the conference through multiple screens, so that the video conference can more clearly display the images of multiple users participating in the conference, and at the same time, make the communication more cordial. [0003] However, in the process of video conferencing, the video source of the multi-screen of the video will not change after it is determined. If the terminal video input fails or there is no video input, it will cause the sub-screen of the multi-screen to have no image, thus affecting The meeting quality of the conference TV is affected, and at the same time, it also affects the user's visual experience. Contents of the invention [0004]...
