Embodiment 1

[0063] see figure 1 , which shows a schematic diagram of the implementation flow of the video receiving method in Embodiment 1 of the present invention. This embodiment can be applied to the video receiving party, and is described in detail as follows:

[0064] In step S101, the display window information of each video receiver is acquired in real time, and the display window information includes: the DPI parameter of the video receiver and the size of the display window of the receiver.

[0065] In this embodiment, the display window information of the receiver needs to be obtained first, and the video sender can adjust the size of the video to be sent according to the display window information. Specifically, obtaining the display window information of each video receiver may include: the video receiver first receives the video stream sent by the video sender, and the video receiver decodes the received video stream to obtain the display window information.

[0066] Among t...

Embodiment 2

[0085] Corresponding to the video receiving method described in the above embodiment, figure 2 A schematic diagram of a video receiving device provided by an embodiment of the present invention is shown, and this embodiment can be applied to a video receiving party. For ease of description, only the parts related to this embodiment are shown.

[0086] see figure 2 , the device may include: a window information acquiring module 101 , a feedback information calculating module 102 , a feedback information sending module 103 , a video receiving module 104 and a playing module 105 .

[0087] The window information acquiring module 101 is configured to acquire the display window information of each video receiver in real time, and the display window information includes: the DPI parameter of the video receiver and the size of the receiver's display window.

[0088] The feedback information calculation module 102 is configured to calculate the feedback information of each video r...

Embodiment 3

[0098] see image 3 , which shows a schematic diagram of the implementation flow of the video sending method in Embodiment 3 of the present invention. This embodiment can be applied to the video sending party, and the details are as follows:

[0099] Step S201, receiving feedback information sent by each video receiver, and obtaining window resolution information according to the feedback information; or directly receiving window resolution information sent by a server.

[0100] In this embodiment, the video sender needs to receive feedback information from the video receiver or window resolution information from the server. When the video sender receives feedback information from the video receiver, the feedback information is The feedback window information of each video receiver needs to calculate the window resolution information according to the feedback window information, and the window resolution information is the basis for the video sender to adjust the output video....

Abstract

The present invention is applicable to the field of communication technology, and provides a video transmission system, receiving / sending / transmitting method and device. The video receiving method includes: obtaining display window information of each video receiver in real time, and the display window information includes: The DPI parameters of the video receiver's dots per inch and the size of the receiver's display window; when the display window information changes, calculate the feedback information of each video receiver based on the display window information of each video receiver; send the video to the video sender or server. Describe the feedback information of each video receiver; the feedback information is used to adjust the video data output by the video sender; receive the video data output by the video sender or server and play it in the display window of the video receiver, the video in the above method The sender can adjust the resolution of the video sent by the video sender according to the video display environment information of the receiver, so as to save transmission bandwidth without affecting the playback quality.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a video transmission system, receiving / sending / transmitting method and device. Background technique [0002] In an ordinary Internet video conference, a video sender and a video receiver are usually included, wherein there are usually multiple video receivers, and the video sender usually sets a resolution coded video in advance and sends it to each receiver. However, when the display window resolutions of the display devices of each video receiver are different, if the video sender directly sends the preset encoded video to each receiver, the preset encoded video may not meet the needs of each receiver. Display requirements, on the one hand, when the resolution of the display window of the receiver’s display device is much smaller than the resolution of the video sent by the sender, it will lead to a waste of transmission bandwidth, resulting in network congest...
