The invention discloses an ultra-high-speed video stream control method and system based on an NI millimeter wave system, including: a transmitter generates a video data stream and encapsulates it into an IP data packet; Network card module; the network card module of the transmitting end buffers and reads the received video stream data, and uses the Nlen and len parameters to fill random numbers in the video data stream; the network card module of the receiving end receives the high-speed data stream from the baseband processing The frame structure is unpacked and repackaged into data packets in a format that the display can recognize and sent to the display; the display at the receiving end receives the data packets, and unpacks them and restores them to the original video for playback and display. The present invention can improve the throughput rate of the wireless communication system, realize ultra-high-speed data transmission in the millimeter wave frequency band, and be combined with the future 5G streaming media application scenarios.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method and system for controlling an ultra-high-speed video stream based on an NI millimeter wave system. Background technique [0002] So far, there have been 4 generations of very mature wireless communication standards in the world, and from the perspective of historical development, the system of each generation will evolve almost every 10 years. Taking the United States as an example, the first generation of FM analog communication in 1981, the second generation of digital communication technology in 1992, the 3G technology in 2001, the Long Term Evolution A (LTE-A) in 2011, and even today 5G, which is advancing (albeit delayed due to the global pandemic), fits this pattern. [0003] With the development of Moore's Law in the past ten years, a large number of electronic devices and application scenarios have emerged one after another, including...
