Problems solved by technology

[0004] However, under extremely weak network conditions (the delay, packet loss rate, and jitter in the network are very large, and the bandwidth is very small), if the above method is followed, in order to ensure the normal transmission of data, the image quality or video quality will be seriously sacrificed, so The transmitted data has a serious distortion rate, and the image or video may even have serious mosaic effects, and problems such as indistinguishable content

Abstract

The embodiment of the invention provides an image data transmission method, device and system, and the method comprises the steps: obtaining original image data; when it is determined that the networkcondition is poor, reducing the color depth of the original image data to obtain to-be-transmitted image data; and transmitting the to-be-transmitted image data to a receiving end. Through the scheme, the distortion rate of the image data can be reduced while the image is normally transmitted under the condition that the network condition is poor.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an image data transmission method, device and system. Background technique [0002] With the continuous development of network technology, the application of transmitting data such as images and videos through the network is becoming more and more extensive. However, affected by factors such as network bandwidth and transmission quality, the network status is unstable, and poor network conditions such as high packet loss rate, high delay, and large jitter often occur. [0003] In order to cope with the above-mentioned poor network conditions, before transmitting images, videos and other data, reduce the image quality or video quality to be transmitted by reducing the image resolution, video frame rate, video compression coding quality, etc., to reduce network transmission. The data volume of the data, so as to ensure that the data can be transmitted normally under...
