Video transmission device with surfing function and implementation method thereof

Abstract

The invention discloses a video transmission device with a surfing function and an implementation method of the video transmission device, which can achieve the surfing function of remote display equipment. The video transmission device comprises an RJ45 socket, a PHY (Physical Layer) chip, a data processing module, a data receiving-transmitting module, a crystal oscillator, and a main data interface, wherein the crystal oscillator is connected with the PHY chip and the data processing module; and the main data interface is connected with the data processing module. According to the device and method, the data processing module converts a 100M RGMII (Reduced Gigabit Media Independent Interface) network signal and a video input signal into a high-frequency 2.5-bit network signal and a high-frequency 13.5-bit video signal respectively, and the high-frequency 2.5-bit network signal and the high-frequency 13.5-bit video signal are subjected to hybrid coding based on a certain format so as to form a continuous 16-bit even and odd field data frame; and the 16-bit even and odd field data frame is output through the data receiving-transmitting module; and meanwhile, the data processing module reversely processes the receiving data from the data receiving-transmitting module by decoding, separating and reducing the frequency, so as to complete duplex communication, therefore, the video display and web-surfing function can be achieved, and the performance of the video display control and monitoring system is improved.

Description

technical field [0001] The invention relates to the field of video communication, in particular to a video transmission device with Internet access function and its realization method. Background technique [0002] At present, display devices such as LED displays, LCD splicing walls, and advertising screens realize functions such as video transmission, screen control, monitoring return, and signal testing through optical fibers or network cables. With the increasing demand of users, the demand for display devices, especially advertising screens, to be able to access the Internet or directly play online videos at the remote end is increasing. [0003] In the existing long-distance video display transmission technology, if it is necessary to realize the Internet access function at the remote end, it is necessary to lay a separate network cable to extend the LAN to the screen body of the display device, and at the same time add Internet access devices or devices to the control ...
