Problems solved by technology

[0005] In the horizontal video conferencing protocol currently supported in the telepresence system, the life-size images obtained by both parties are limited to the upper body of the participants. To be precise, they should be called life-size half-body images, although most of the time in the meeting is sitting. But for speeches, demonstrations, training, etc., the half-length display will reduce the quality of communication and affect the atmosphere of the scene

Embodiment 1

[0039] see figure 1 , the embodiment of the present invention provides a method for sending video information, specifically including:

[0040] Step 101: Obtain the video information of the first conference site;

[0041] Step 102: Obtain the video information of the second conference site according to the video information of the first conference site and the vertical video format supported by the second conference site;

[0042] Wherein, the vertical video format is a video format in which the aspect ratio of the video information is less than 1;

[0043] Step 103: Encoding the obtained second conference site video information to obtain the second conference site video encoding information;

[0044] Step 104: Send the video encoding information of the second conference site to the second conference site, so that the second conference site displays the video information of the second conference site.

[0045] In this embodiment, the vertical video format supported by the s...

Embodiment 2

[0059] see figure 2 , the embodiment of the present invention provides a method for sending video information, including:

[0060] Step 201: A terminal at a first conference site acquires video information of the first conference site.

[0061]In this embodiment, the first telepresence site directly communicates with other sites, where the other sites include a telepresence site or a common video conference site. In this embodiment, the direct communication between the first telepresence site and the second telepresence site is taken as an example for description. At the beginning of the video conference, the terminals at the video conference site exchange their respective video format support capabilities. After receiving the video format supported by the second telepresence site, the first telepresence site learns that the video format supported by the second telepresence site is vertical To the video format (that is, the video format whose aspect ratio of the video infor...

Embodiment 3

[0083] see image 3 , the embodiment of the present invention provides a method for sending video information, including:

[0084] Step 301: The media controller obtains the video information of the first conference site.

[0085] In this embodiment, the telepresence site communicates with other sites through an MCU (Multipoint Control Unit, multipoint processing unit), including a telepresence site or a common video conference site, where the MCU is also called a media controller. In this embodiment, the first telepresence site and the second telepresence site are connected through a media controller as an example for illustration. Wherein, at the beginning of the video conference, the terminals at the video conference site send respective video format support capabilities to the media controller, where the media controller receives the video formats supported by the first telepresence site and the second telepresence site, and then It is known that the second telepresence ...

Abstract

The invention discloses a method and a device for sending and receiving video information, belonging to the field of video communication. A method for sending video information includes the steps of: obtaining video information of a first meeting place, wherein the video information of the first meeting place adopts a vertical video format with a length-width ratio being smaller than 1; obtaining video information of a second meeting place according to the video information of the first meeting place and a video format supported by the second meeting place; encoding the obtained video information of the second meeting place to obtain video encoding information of the second meeting place; and sending the video encoding information of the second meeting place to the second meeting place by a data transmission network, thereby enabling the video encoding information of the second meeting place to be displayed at the second meeting place. The vertical video format is added in a video meeting protocol; and through obtaining the vertical video information, participants in a meeting can obtain the image of the whole body of the other party, therefore the visual feeling to the scene of the video meeting is improved and the liveness, the reality sense and the communication quality of the participants are improved.

Description

technical field [0001] The invention relates to the field of video communication, in particular to a method and device for sending and receiving video information. Background technique [0002] With the development of communication technology, telepresence conference has become an important way of communication. Technically speaking, the concept of telepresence is to transmit real feelings through the network, to reproduce the real environment through the network and to realize the real experience through the network. In a telepresence meeting, participants can feel as if they were there. [0003] Existing telepresence conferences support horizontal video conferencing protocols, so horizontal display devices and corresponding video capture and video processing devices are generally used, such as 16:9 display screens and corresponding video capture devices, 4:3 With the display screen and the corresponding video capture device, the participants get the upper body images of ...
