Problems solved by technology
[0014] It can be seen that the camera video service brings a large amount of loop traffic and uncompressed video traffic in a virtualized environment, and because the network connection between the client computer and the virtual machine is an IP network, the network may even be in the scope of a wide area network, and its network delay bandwidth and other indicators cannot meet the transmission needs of these video streams

Embodiment Construction
[0062] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined arbitrarily with each other.
[0063] Compared with the traditional virtual desktop environment, the virtual desktop environment of this embodiment adds a dedicated video service channel between the client machine and the virtual machine, that is, the video service data of the camera is exchanged between the client machine and the virtual machine and is independent of the peripheral mapping channel communication channel. Other video service data interactions between the client computer and the virtual machine can use the video service dedicated channel, or use the original peripheral mapping channel. In add...

A camera video processing method and corresponding equipment applied to a virtual desktop environment. A client computer receives an instruction to start a camera video service and window information sent by a virtual machine through a dedicated video service channel. The camera video service has an echo function; Start the camera, receive the video data collected by the local camera, and generate an uncompressed video stream; the client generates display data according to the window information and the uncompressed video stream and echoes it on the monitor; among them, the dedicated channel for video services is the client A communication channel that exchanges camera video service data with the virtual machine and is independent of the peripheral mapping channel. The virtual machine sends instructions and window information to start the camera video service to the client through the video service dedicated channel, and when the camera video service has the echo function, the echo function is blocked. The invention can avoid a large amount of loop flow, so that the video service can be carried out normally.
Description
technical field [0001] The present invention relates to video compression, more specifically, to a camera video processing method applied to a virtual desktop system and a corresponding client and virtual machine. Background technique [0002] Desktop virtualization is to install a virtual host system on a physical server, and the virtual host system simulates the hardware resources required for the operation of the operating system, such as: CPU, memory, network card, storage, etc. The operating system runs on these virtual hardware resources, so that multiple operating systems can share the hardware resources of the physical server, thereby improving resource utilization. Desktop virtualization hosts all desktop virtual machines (referred to as virtual machines) in the data center and manages them in a unified manner. The storage, computing, and execution of virtual desktops (including operating systems, applications, and user data) The operating system desktop is present...
