Problems solved by technology

In the prior art, the signal is transmitted through the VGA cable, and there is a limitation on the transmission distance, and because the signal line of the VGA signal adopts an analog transmission mode, the computer graphics card must convert the digital signal into an analog signal when outputting an image. In the process of digital / analog conversion, signal loss will be caused. In addition, the analog signal is easily disturbed during transmission, which will affect the quality of the image.

Embodiment 1

[0020] This embodiment proposes a device for remotely displaying a desktop image of a local computer through a video conferencing system, including a local computer and a conference computer. Such as image 3 As shown, the local computer includes a desktop image acquisition module and a network sending module; the conference computer includes video conferencing software, a virtual video capture card driver module and a network receiving module. exist image 3 In , both the local computer and the conference computer contain a network interface, which is a common interface for connecting network cables.

[0021] Each module is described in detail below:

[0022] The desktop image collection module is used for collecting desktop images of the local computer. There are many ways to realize this module. In the present invention, two ways are proposed, but it can also be realized in other ways at the same time, and it is not limited thereto. These two methods are respectively: o...

Embodiment 2

[0031] This embodiment proposes a device for remotely displaying a desktop image of a local computer through a video conferencing system, including a local computer and a conference computer. Wherein, the local computer includes a desktop image acquisition module and a network sending module; the conference computer includes video conference software, a virtual video acquisition card driver module and a network receiving module. In this embodiment, both the local computer and the conference computer may be notebook computers including wireless network cards, and data transmission is performed between the local computer and the conference computer through the wireless network card.

[0032] In this embodiment, the desktop image acquisition module is a desktop image acquisition module that collects desktop images of the local computer through mirroring. The network sending module, the virtual video capture card driver module and the network receiving module are all the same as t...

Abstract

The invention relates to the technical field of video communication and in particular provides a device for remotely displaying local computer desktop images through a video conference system. The device comprises a local computer and a conference computer, wherein the conference computer comprises video conference software, a virtual video acquisition card drive module and a network receiving module; and the local computer comprises a desktop image acquisition module and a network sending module. In the device, the traditional video conference system software does not need to be modified, and hardwares such as an RGB (red, green, blue) acquisition card and the like do not need to be increased in the traditional video conference system, thus the fund investment of users and the subsequent hardware maintenance cost are not increased. Moreover, the local computer images are transmitted by adopting network digitization, thereby avoiding the limit of transmission distances and the loss of image quality.

Description

technical field [0001] The invention relates to the technical field of video communication, and specifically proposes a device for remotely displaying a desktop image of a local computer through a video conference system. Background technique [0002] At present, video conferencing systems based on IP networks have been widely used in daily life. Due to the popularization of computers, a large amount of daily work can be done by computers. For remote communication tools such as video conferencing systems, not only sound and video image transmission capabilities are required, but computer desktop image transmission capabilities are also required. In order to meet the requirements of computer desktop image transmission, video conferencing system manufacturers have extended the video conferencing system protocol on the basis of the original video conferencing, and proposed the concept of dual streams, that is, video images and computer desktop images are transmitted separately...
