Embodiment 1

[0054] figure 2 It is a flow chart of the steps of the cloud desktop-based video stream processing method in this embodiment. Refer to the following figure 2 The method in this embodiment will be described in detail.

[0055] In step S210, the cloud desktop server monitors the network status between the cloud desktop server and the terminal to determine network parameters. Wherein, the network parameters include but are not limited to network delay time, packet loss rate, and throughput. By monitoring the network status in real time, the load of the network can be judged according to the network parameters.

[0056] For example, if the network delay time is too large, the packet loss rate increases, or the throughput decreases, it indicates that the current network transmission status is not good, and video frames need to be compressed to a greater extent to adapt to the current network conditions. If the network delay time is small, the packet loss rate is small, or the...

Embodiment 2

[0096] This embodiment provides a video stream processing device based on cloud desktop, its structure is as follows Image 6 shown. The device 600 includes a monitoring unit 610 , a receiving unit 620 , an adjusting unit 630 and a processing unit 640 .

[0097] The monitoring unit 610 is used to monitor the network status between the cloud desktop server and the terminal to determine network parameters. The receiving unit 620 is configured to receive the performance parameters of terminal operation and determine the terminal operation status. The adjustment unit 630 is connected to the monitoring unit 610 and the receiving unit 620 respectively, and is used to adjust the video frame compression rate and frame rate according to the terminal's operating status and network parameters.

[0098] The processing unit 640 is connected to the adjustment unit 630, and is configured to compress the video data based on the video frame compression rate and frame rate, so as to obtain a ...

Abstract

The invention discloses a method and a device for processing a video stream based on a cloud desktop. The method comprises the steps of monitoring the network state between a cloud desktop server and a terminal to determine network parameters, receiving the running performance parameters of a terminal and determining the running status of the terminal, adjusting a video frame compression ratio and a frame rate according to the running status of the terminal and the network parameters, and compressing video data based on the video frame compression ratio and the frame rate to obtain the video stream matched with the present running status of the terminal and the network state. According to the method for processing the video stream based on the cloud desktop, the video frame compression ratio can be adjusted in real time according to the load condition of the current network and the frame rate of the video frames is adjusted according to the running status of the terminal, and therefore, the compression method of cloud desktop video transmission is optimized and the requirement of a cloud desktop system on bandwidth is reduced.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a cloud desktop-based video stream processing method and device. Background technique [0002] With the continuous development of cloud computing, virtual desktop solutions are increasingly mature, and desktop virtualization has become a typical cloud computing application. Cloud desktop is a computing model based on a central server, built on the basis of server virtualization. All desktop virtual machines are hosted in the data center and managed in a unified manner. At the same time, users can obtain a complete PC experience and use virtual desktop services according to their needs. [0003] In the cloud desktop mode, the transmission of graphics, images and audio can be completed between the desktop server and the user terminal. The desktop server needs to transmit the desktop image to the user terminal in real time, and also process the input information re...
