The present invention provides a system for long-distance high-definition transmission. The system includes at least one video interface, at least one Video Decoder module and / or Video Receiver module, FPGA module, HDMI Transmitter module, HDBaseT Transmitter module, and the FPGA module sends digital signals To the HDMI Transmitter module; the HDMI Transmitter module converts the digital signal into an HDMI signal; the HDBaseT Transmitter module converts the HDMI signal into a digital signal of the HDBaseT protocol, and sends the digital signal of the HDBaseT protocol to the HDBaseT display device, thereby according to different The video signals of different types and resolutions input by the interface can simultaneously collect multiple video signals through flexible application configuration. For high-definition video signals, the high-definition transmission technology HDBaseT can be used for long-distance transmission of uncompressed video signals. The signal is restored to a video signal through the HDBaseT receiving device, and then input to the display device through the HDMI interface for display, which is used to realize the application scenario of high-definition video signal without delay and long-distance transmission without compression.
Description
technical field [0001] The present invention relates to the communication field, in particular to a system for long-distance high-definition transmission. Background technique [0002] With the popularity of high-definition video signal applications, more and more multimedia video and audio scenarios use high-definition signal sources, such as video conferencing applications in the conference room industry, remote video teaching applications in the education industry, and medical surgery video teaching applications. application mode. At the same time, with the development of video hardware technology, the multimedia industry puts forward higher requirements for video clarity. High-definition video signal sources such as 720P@60Hz and 1080P@60Hz are becoming more and more popular. How to record high-definition multimedia information quickly and effectively Realizing the recording, dissemination and sharing of multimedia information is the main goal of the recording and broad...
