Embodiment 1

[0153] The video switching scene and figure 2 The difference is that before each terminal joins the multipoint conference, the binding relationship of each terminal is statically created on the service management platform. For the specific video switching process, please refer to Figure 12 shown.

[0154] Step 120: Configure the binding relationship between master and slave terminals on the service management platform according to the first method described above, specify the master terminal and slave terminal of each bound terminal, and report to the MCU, the current configuration of terminal 1 and terminal 4 is a bound terminal, and terminal 1 is the master terminal, and terminal 4 is the slave terminal.

[0155] Step 121: The service management platform sends command information for holding a multipoint conference including Terminal 1, Terminal 2 and Terminal 3 to the MCU.

[0156] Step 122: The MCU establishes calls with Terminal 1, Terminal 2, and Terminal 3 in sequen...

Embodiment 2

[0165] The video switching scene in the second embodiment and figure 2 The difference is that when each terminal joins a multipoint conference, the binding relationship of each terminal is dynamically created on the terminal side. For the specific video switching process, please refer to Figure 13 shown.

[0166] Step 130: When a slave terminal joins a multipoint conference, configure the binding relationship between the master and slave terminals according to the second method described above, specify the master terminal bound to each slave terminal, and currently configure Terminal 1 and Terminal 4 is a bound terminal, and terminal 1 is the master terminal, and terminal 4 is the slave terminal.

[0167] Step 131~step 139, with Figure 12 Steps 121 to 129 are the same and will not be repeated here.

Embodiment 3

[0169] The video switching scene of the figure 2 The difference is that after each terminal joins a multipoint conference, the binding relationship of each terminal is dynamically created on the terminal side through the conference control signaling. For the specific video switching process, please refer to Figure 14 shown.

[0170] Step 140: The service management platform sends command information for holding a multipoint conference including Terminal 1, Terminal 2, Terminal 3, and Terminal 4 to the MCU.

[0171] Step 141: The MCU establishes calls with Terminal 1, Terminal 2, Terminal 3, and Terminal 4 in sequence.

[0172] Step 142: The conference manager broadcasts terminal 1 on the business management platform, user A in the conference room where terminal 1 is located speaks, and the camera of terminal 1 is aimed at user A.

[0173] Step 143: Terminal 1 uploads to the MCU a video code stream containing user A's image, and an audio code stream containing user A's voic...

Abstract

The invention discloses a video switching method, a video switching device and a video switching system in order to solve the problem that the existing video switching process is cumbersome and inconvenient in operation. The method comprises the following steps: an MCU establishes a video conference call connection with multiple terminals; the MCU detects the voice of the multiple terminals, and takes the detected terminal with the highest voice in the multiple terminals as a first terminal; the MCU gets the association relationship between the first terminal and a second terminal with the highest voice detected last time in the multiple terminal; and the MCU makes a broadcast video source switched from the second terminal to the first terminal based on the association relationship. Thus, no human intervention is needed for video switching between terminals, a video source can be switched automatically based on the association relationship between terminals, operation is simple, and the complexity of manual operation is reduced.

Description

technical field [0001] The present invention relates to the technical field of video conferencing, in particular to a video switching method, device and system. Background technique [0002] The video service is a multimedia service that integrates information such as voice, image, and data for long-distance transmission. The service provided by the video service is video conferencing. Such as figure 1 As shown, in the prior art, when the number of terminals participating in the meeting is more than two, it must be controlled by a multipoint control unit (Multipoint Control Unit, MCU), and all terminals participating in the meeting must be connected to the MCU through a standard interface. , It is also necessary to connect the venue and the MCU through the communication network, and the physical transmission channel can be optical fiber, cable, microwave or satellite. [0003] After each terminal joins the conference, when user A uses a new terminal to join the conference,...
