Method and system for improving image data transmission speed

Abstract

The invention relates to the field of desktop virtualization, and particularly relates to a method for improving an image data transmission speed. The method comprises the following steps: collecting image data; compressing the image data; encoding the compressed image data; transmitting the encoded image data to a virtual machine; and analyzing the encoded image data by the virtual machine. On the basis of using a high-definition image device based on a desktop cloud USB port redirection mode, the high-definition image data collected by a client are compressed, so that when the client transmits the image data to the virtual machine, the data transmission amount is reduced temporarily, and the compressed image data are encoded to form a specific signal orgniazation form that is unlikely to interfere and can be restored from a transmission error, thereby improving the transmission reliability; after the virtual machine receives the image data transmitted by the client, the virtual machine analyzes the encoded image data into the image data of a high-definition image for output; and thus the transmission speed of the image data is improved without affecting the definition of the image.

Description

technical field [0001] The invention relates to the field of desktop virtualization, in particular to a method and system for increasing the transmission speed of image data. Background technique [0002] A high-definition image device (such as a high-definition camera) is a video device, and video service data belongs to video images and is calculated in frames. But it is a USB device. From the perspective of the USB protocol, the business data is a URB (USB REQUEST BLOCK). When using the USB port redirection method, in the desktop cloud, the focus is on the transparent transmission of URB messages between the image device and the virtual machine. ; On average, each frame of data corresponds to 30 URB messages, and the processing time of each URB message is about ten milliseconds, and it takes about 500 milliseconds to process one frame of data; the data format collected at the same time is YUV format data, and the transmission bandwidth is large. The data processing delay...
