Problems solved by technology

[0006] 1. The problem of traffic occupation. The double transmission of such a large traffic in the network will cause a certain pressure on the network, especially if it is used in an environment where the network bandwidth is not enough, such as across a wide area network or wireless WLAN, etc.;
[0007] 2. The delay of the image, due to the delay of the network and the transmission of large traffic will cause the delay of the image. The change of the image must be transmitted to the server first, and then fed back from the server to the terminal to feel it, so the user experience is not good.

Embodiment Construction

[0024] The present invention relates to a method for redirecting camera peripherals in a virtualized environment. The specific development ideas of the method are as follows: figure 2 As shown: For the redirection of the camera peripheral, due to the relatively large amount of data, it needs to be transmitted in the corresponding dedicated virtual channel. The client remote virtual desktop’s read and write requests for the redirected camera peripheral are intercepted by the desktop transmission protocol. Read and write requests and data are forwarded to the client, and then the camera peripherals in the client respond to the request, respond to the operation, and return the response result data to the server through the desktop transfer protocol, and then the server sends the received response Data is sent to the camera peripheral.

[0025] In the present invention, virtualization refers to using software to simulate various hardware resources (including CPU, RAM, hard disk a...

Abstract

The invention discloses a redirection method for a camera arranged in a virtual environment. According to the method, information is transmitted by a remote transmission protocol, and thus a terminal directly reads the data of the camera in local, and directly decodes in a local remote desktop window to display an image, namely the completely local displaying is achieved for a user; two times of data transmission on the network is not needed, and no delay phenomenon is caused, meanwhile, no image data needs to be transmitted on the network, and only several pieces of simple communication information are transmitted on the network, so that the network load is greatly reduced and the user experience is greatly enhanced.

Description

technical field [0001] The invention relates to a method for redirecting camera peripherals in a virtualized environment, and belongs to the technical field of application publishing. Background technique [0002] Driven by the advancement of science and technology, network technology is increasingly developed, and the demand for servers is also increasing. At present, various industries around the world have begun to implement virtualization applications. Virtualization can be used to integrate servers, storage, networks, and desktop applications. Future development will rise to cloud computing. Virtualization is the foundation of cloud computing. Desktop virtualization is to perform server virtualization on servers in the data center, generate a large number of independent desktop operating systems (virtual machines or virtual desktops), and send them to terminal devices according to a proprietary virtual desktop protocol. The user terminal logs in to the virtual host th...
