Embodiment 1

[0066] This embodiment provides a video processing system for telepresence, the system includes: a plurality of video acquisition devices (VC1, VC2, VC3), a plurality of video display devices (VD1, VD2, VD3), a local terminal and a remote terminal, wherein the multiple video acquisition devices are connected to the local terminal, and the multiple video display devices are connected to the remote terminal. The video capture device is used to collect original video images and send the collected original video images to the local terminal. The local terminal acts as the sending end of video images and stitches the original video images sent by each video capture device to obtain a composite video. image, and then encode and send the composite video image; the remote terminal, as the receiving end of the video image, receives the composite video image sent by the local terminal, decomposes the composite video image, and obtains multiple original video images images, and then send...

Embodiment 2

[0084] The composition and structure of the telepresence video processing system in this embodiment is as follows image 3 As shown, the composition structure of the video processing system in Embodiment 1 is basically the same, the difference is that the video processing system in this embodiment also includes a multi-point processing unit (MCU), and the local terminal and the remote terminal pass through the MCU. Networking is performed, that is, data exchange is performed between the local terminal and the remote terminal through the MCU.

[0085] The process of video processing in this embodiment is as follows Figure 4 As shown, specifically, the following steps may be included:

[0086] Step 401: basically the same as step 201, the difference is that media capability negotiation is not directly performed between the local terminal and the remote terminal, but is performed through the MCU.

[0087] That is to say, when media capability negotiation is performed, the loca...

Embodiment 3

[0095] This embodiment provides a telepresence video processing system, such as Figure 5 As shown, the system includes: a plurality of video acquisition devices, a plurality of video display devices, MCU, a first terminal, a second terminal and a third terminal, wherein the first terminal is connected with three video acquisition devices (VC1, VC2 , VC3) and three video display devices (VD4, VD5 and VD6); two video capture devices (VC4, VC5) and two video display devices (VD1, VD2) are connected to the second terminal; the third terminal is connected to There is a video capture device (VC6) and a video display device (VD3). The first terminal, the second terminal and the third terminal can all serve as the sending end and the receiving end of the video image at the same time. The first terminal, the second terminal, and the third terminal form a network through the MCU. When the first terminal serves as the local end, the second terminal and the third terminal serve as the c...

Abstract

The invention discloses a video processing method. The method includes: splicing two or more original video images according to predetermined video arrangement information to obtain a composite video image; Encoding; sending the encoded composite video image. Correspondingly, the present invention also discloses a video processing device and system, which can ensure strict synchronization between multiple video channels in a telepresence conference; and solves the problem of determining the output position of video images, so that the telepresence conference presents realistic communications. Effect.

Description

technical field [0001] The invention relates to video conferencing technology, in particular to a video processing method, device and system. Background technique [0002] Telepresence is deeply loved by high-end users for its real sense of presence. The key technical indicators of the telepresence system are listening to the voice, identifying the position, and the size of the real body. [0003] In the telepresence conference system, in order to achieve the effect of real body size and listening to the voice, a terminal venue with multiple display screens, each display screen displays the image of a participant in a seat at the far end, and corresponds to the audio output position. That is, the display screen that displays the speaker's image in the conference site, corresponding to the output direction of the speaker's audio. For example, in a three-screen venue, if the left seat speaks, the voice should be heard from the left. Therefore, the location of the remote imag...
