Problems solved by technology

[0004] At present, the size of the signal displayed in the form of an embedded window is relatively small, and the signal displayed in the form of an embedded window will block part of the signal displayed in full screen mode, resulting in poor display effect of the main stream signal and auxiliary stream signal
[0005] To sum up, the current VCT control will display the restored mainstream signal and auxiliary stream signal on the display device corresponding to the meeting place in PIP mode, resulting in relatively poor display effect of the mainstream signal and auxiliary stream signal

Embodiment 1

[0229] Such as Figure 7 As shown, taking the mobile device as a PAD, the main playback device as a large screen in the venue, and the establishment of a direct connection channel between the mobile device and the VCT held by the participants in the venue as an example, the conference signal playback method of the embodiment of the present invention is carried out. introduce.

[0230] Step 701, controlling the large screen in the venue to simultaneously play the first sub-category signal and the mainstream signal included in the auxiliary stream signal in a PIP manner;

[0231] Step 702, such as Figure 5A As shown, based on wired IP or wireless IP, establish a direct connection channel between each PAD and VCT;

[0232] Step 703, controlling the VCT to obtain the capability information of each PAD, and controlling the VCT to perform list management of each PAD with established connection channels;

[0233] Step 704, control each PAD to log in to the web of VCT to download ...

Embodiment 2

[0251] Such as Figure 8 As shown, take the mobile device as a PAD, the main playback device as a large screen in the venue, and establish an indirect connection channel between other mobile devices and the VCT between the mobile devices held by the participants in the venue, and implement the present invention An example conference signal playback method will be introduced. It should be noted that the implementation of establishing an indirect connection channel between a mobile device and a VCT through multiple levels of other mobile devices is the same as the embodiment of the present invention establishing a connection between a mobile device and a VCT through a level of other mobile devices. The implementation manners of the indirect connection channels between are similar, and will not be repeated here.

[0252] Step 801, controlling the large screen in the venue to simultaneously play the first sub-category signal and the mainstream signal included in the auxiliary stre...

Embodiment 3

[0277] Such as Figure 9 As shown, taking mobile devices PAD1, PAD2, PAD3, and PAD4 in the venue, the main playback device is the large screen in the venue, and the direct connection channel between the mobile devices held by the participants in the venue and the VCT is established as an example. The method for playing a conference signal in the embodiment of the invention will be introduced.

[0278] Step 901, the VCT sends the main stream signal and auxiliary stream signal to the large screen at the same time;

[0279] Step 902, the large screen simultaneously plays the received main stream signal and auxiliary stream signal in PIP mode;

[0280] Step 903, VCT sends an inquiry message to PAD1, PAD2, PAD3 and PAD4 whether to agree to establish a connection with itself;

[0281] Step 904, PAD1, PAD2 and PAD3 send a consent message to the VCT, and PAD4 sends a disapproval message to the VCT;

[0282] Step 905, such as Figure 5A As shown, VCT establishes direct connection c...

Abstract

The invention relates to the technical field of communication, in particular to a method and device for meeting signal playing, a video meeting terminal and mobile devices, and the display effect of mainstream signals and auxiliary stream signals can be improved. The method for meeting signal playing includes the steps that connecting channels among the mobile devices held by conventioneers in a meeting place and the video meeting terminal are built; first kind signals in signals to be played are sent to the mobile devices for playing through the built connecting channels, wherein the signals to be played are signals which are received by the video meeting terminal and to be played; second kind signals in the signals to be played are sent to a main playing device in the meeting place for playing. The display effect of the mainstream signals and the auxiliary stream signals is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a conference signal playing method and device, a video conference terminal, and a mobile device. Background technique [0002] Video service is a multimedia service that integrates information such as voice, image and data for long-distance transmission. At present, a widely used video service is VC (Video Conference, video conferencing). Among them, VC refers to the use of audio and video Communication technology and equipment are a communication method in which meetings are held simultaneously between two or more locations through transmission channels. Such as figure 1 As shown, the current video conference system generally includes at least two video conference terminal subsystems, transmission channels and MCU (Multipoint Control Unit, multipoint control unit), such as figure 2 As shown, the video conference terminal subsystem located in each venue includes a VCT (...
