Problems solved by technology

[0002] When transmitting video signals, in order to ensure the integrity of video signals, the scheme of directly transmitting original video signals can be adopted, but this scheme usually occupies a large network transmission bandwidth and resources, in order to reduce the network transmission bandwidth and resources occupied by video transmission resources, in the prior art, the scheme of only transmitting the feature vector in the video signal is also adopted. In the scheme, the video transmission terminal locates the area containing important information in the video signal, extracts the feature vector from it, and only transmits the feature vector. This scheme It can reduce the transmission bandwidth and resource occupancy. However, it is usually difficult for the receiving end of the video signal to restore the complete original video signal by using this scheme.

Embodiment 1

[0030] This embodiment provides a video transmission method, such as figure 1 shown, including the following steps:

[0031] 101. The terminal acquires the first frame of image in the video signal;

[0032] The terminal in this embodiment may be, for example, a video monitoring terminal, a video shooting terminal, etc. The terminal in this embodiment may be integrated with a video acquisition component such as a camera, and of course may also be connected with an external video acquisition component such as a camera.

[0033] The video signal in this embodiment may be collected by a video collection component. For example, when the terminal in this embodiment is a video surveillance terminal, the video signal is collected by a video collection component such as a camera.

[0034] The video signal in this embodiment is composed of images frame by frame. When using the video transmission method provided by this embodiment to transmit video signals, different transmission method...

Embodiment 2

[0075] In this embodiment, a video transmission terminal, such as image 3 As shown, it includes: an acquisition module 21, a detection module 22, an extraction module 23, a transmission module 24 and a judgment module 25; wherein:

[0076] Obtaining module 21, obtaining the first frame image in the video signal;

[0077] A detection module 22, detecting whether specific information is contained in the first frame image;

[0078] An extraction module 23, configured to extract all information from the first frame image as background information of the first frame image when the detection module 22 detects that the first frame image does not contain the specific information; A transmission module 24, configured to send the background information of the first frame image to the server;

[0079] The extraction module 23 is further configured to extract the specific information from the first frame image as the first frame image when the detection module 22 detects that the first...

Embodiment 3

[0093] This embodiment provides a video transmission system, such as Figure 4 As shown, including terminal 10 and server 20;

[0094] The terminal 10 is configured to acquire a first frame image in the video signal; detect whether the first frame image contains specific information; if the terminal detects that the first frame image does not contain the specific information, extracting all the information from the first frame image as the background information of the first frame image, and sending the background information of the first frame image to the server;

[0095] The server 20 is configured to receive and store the background information of the first frame of image, and use the stored background information to restore the image to obtain the first frame of image;

[0096] The terminal 10 is further configured to detect that the first frame image contains the specific information, extract the specific information from the first frame image as the specific informatio...

Abstract

The present invention provides a video transmission method, terminal and system. The method includes: the terminal detects whether the Nth frame image contains specific information, and the value of N is a natural number greater than or equal to 2; if the terminal detects that the Nth frame image contains Specific information, the terminal extracts specific information from the Nth frame image as the specific information of the Nth frame image and extracts all information except the specific information as the background information of the Nth frame image, and determines whether the background information of the Nth frame image is consistent with the previous Whether there is any change in the background information of one frame of image; if the terminal determines that there is no change in the background information of the Nth frame of image compared with the background information of the previous frame of image, it sends the specific information of the Nth frame of image to the server, and the server Receive the specific information of the Nth frame image, obtain the previously stored background information, and use the received specific information of the Nth frame image and the previously stored background information to perform image reconstruction to obtain the Nth frame image.
