Problems solved by technology
However, the amount of video data is large, and the wired network will also be unstable, causing data congestion, which will cause serious delays after a long time; if the working environment is not fixed and mobility is required, then a wireless network must be used. Nowadays, wireless network cards The work of the computer becomes unstable with the change of the environment, which will lead to a significant drop in the quality of video transmission, and it is easy to cause ghosting, jitter, and blurred screens on the screen.

Embodiment Construction
[0020] The drawings are for illustrative purposes only, and should not be construed as limitations on this patent; in order to better illustrate this embodiment, some parts in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product;
[0021] For those skilled in the art, it is understandable that some well-known structures and descriptions thereof may be omitted in the drawings. The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] A method of saving bandwidth for video transmission in a LAN. This method has no restrictions on routers, and ordinary routers can be used without any additional settings. When the devices (sender and receiver) in the LAN start up, an independent monitoring thread is opened in the background, the Socket is initialized, the machine is configured as the server, and the device that establishes a communication...

The invention discloses a method for video transmission in a local area network. When a sending end and a receiving end in the local area network transmit a video, the sending end is disconnected from a router and establishes point-to-point connection with the video receiving end; the video is sent to the video receiving end directly through a point-to-point manner; and, after the video is transmitted, connection among the sending end, the receiving end and the router is recovered. In the invention, when equipment in the local area network needs to transmit a video flow, video data is not forwarded through the router and directly sent to terminal equipment; therefore, the bandwidth of the router is not occupied; congestion of the router cannot be caused; and thus, the bandwidth of the router is greatly saved.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, relates to a bandwidth-saving method for video transmission in a local area network. Background technique [0002] With the diversification of multimedia services, each terminal has different requirements for service quality in different networks, and its terminal processing capabilities are also different. For some terminal devices with low processing capabilities, it is difficult to perform video compression. With the launch of some social networks and video chat tools, it is necessary to generate, write, process, and search different types of audio and video, images, graphics, etc., and the processing and storage capabilities of the client are increasingly demanding. The capacity is limited, the power consumption is relatively high, and the transmission process will be directly affected by the network signal. The compression capability of the LAN t...
