AI Technical Summary

Problems solved by technology

Since the specifications of the transmission medium are relatively fixed, flexible adjustments cannot be made once the installation is completed
Therefore, image data will inevitably be blocked during the transmission process, that is, the currently transmitted image data is too large, while the data transmission volume of the matching transmission medium is too small, etc., resulting in image data in the transmission process. Congestion, or even packet loss, will cause the image display device to be unable to view clear and complete images after receiving the above-mentioned image data, and even the image display device will not be able to play the above-mentioned image data
[0004] In summary, there is currently no effective solution to the problem that image data cannot match the transmission medium during transmission

Embodiment 1

[0075] see figure 1 , figure 2 with image 3 The image transmission method proposed in this embodiment specifically includes the following steps:

[0076] Step S101: When the image transmission request trigger is received, the image sending end detects the data transmission volume of the transmission medium connected to it in real time. During the implementation process, a transmission medium, namely the image image, is set between the image sending end and the image receiving end The transmission is carried out by means of a transmission medium, and the trigger condition of the transmission is the triggering of an image transmission request (for example, button trigger, touch control, etc.) sent by the user terminal. In this embodiment, the transmission medium between the image receiving end and the image sending end includes A type of network cable or electronic circuit. The network cable is usually used for the transmission of images with a longer distance and larger cap...

Embodiment 2

[0115] see Figure 4 , the present embodiment provides an image transmission device comprising: a data transmission amount detection module 1, used for detecting the data transmission amount of the transmission medium connected to it by the image sending end in real time when receiving an image transmission request trigger; Module 2 is used for the image sending end to retrieve the image data corresponding to the image transmission trigger from the data storage end; the resolution value extraction module 3 is used for the image sending end to extract the foreground resolution value and the main body resolution of the image data respectively value and the background resolution value; the resolution value comparison module 4 is used to compare the size of the foreground resolution value, the subject resolution value and the background resolution value at the image sending end; the transmission setting module 5 is used for when the comparison result is The main body resolution va...

Abstract

The invention provides a video image transmission method and a device thereof, relating to the technical field of data transmission, wherein the video image transmission method comprises the followingsteps of: detecting, by a video transmitting end, a data transmission quantity of a transmission medium connected thereto; when a main body resolution value of the image data is greater than the foreground resolution value, and when the main body resolution value is greater than the background resolution value, dividing each frame of image of the video data to be transmitted into a plurality of image blocks; when the data transmission amount is smaller than the pixel, calculating the difference between the data transmission amount and the pixel, reducing the pixel of the selected image blocksby selecting image blocks with the least varieties, and calculating the reduction amount of pixel of the image blocks; when the reduction amount and the difference are equal, updating the image blocks with the least color type as the saved image blocks, and putting the un-updated image blocks and the saved image blocks into a transmission medium for transmission, thereby improving the matching degree between the image data and the transmission medium.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to an image transmission method and device. Background technique [0002] With the development of science and technology and the popularization of computer technology, various image and image data using high-tech technology have also brought people a new sensory experience. The stage effect produced by 3D technology, the virtual reality game experience produced by VR technology, the remote multi-person video screen realized by video chat technology, etc., are all acquired at the front end (for example, 3D glasses, camera, etc.) After the image data is transmitted to the viewer's human eyes after passing through the transmission medium using a certain transmission technology. [0003] However, during the transmission process, the above-mentioned multiple forms of image data need to be transmitted through the transmission medium (eg, network cable, electronic circuit, etc.)...
