Problems solved by technology
[0003] However, due to the continuous improvement of video image quality, its data volume is also increasing, which brings a certain degree of challenge to video transmission.
At present, each pixel of video in HDMI format contains at least four bytes. If chaos theory is used for encryption during transmission, the security of communication will be greatly improved, but the real-time performance of transmission still needs to be improved.
At present, people mainly study chaotic secure communication through numerical simulation. Compared with voice and images, video has the characteristics of large data volume and strong real-time performance. During the transmission process, it is easy to block the transmission channel, affect the transmission efficiency, and cause video freezes.

The invention discloses a video encryption transmission method. The method detects the identification bit corresponding to the byte in each pixel of the video in HDMI format; only R byte, G byte and B word in each pixel are detected. After receiving the video data, the receiving end inserts the extended data to restore the video format in the video data, and performs chaotic decryption on the video data after inserting the extended data; wherein, each The R byte, G byte, B byte in the pixel and the byte of the tag extension data all correspond to different identification bits, and the bytes are detected, encrypted or decrypted according to the identification bits. Thus, the amount of data in the transmission process of the video data is reduced, the congestion of the transmission channel is avoided, and the transmission efficiency and processing efficiency of the video data are also improved. Correspondingly, a video encryption transmission device, system, equipment, and computer-readable storage medium disclosed in the present invention also have the above-mentioned technical effects.
Description
technical field [0001] The present invention relates to the technical field of data transmission, and more specifically, to a video encryption transmission method, device, system, equipment and computer-readable storage medium. Background technique [0002] With the development of video technology, video production, transmission and display technology are changing with each passing day, which greatly improves the viewing and comfort of video. [0003] However, due to the continuous improvement of video image quality, its data volume is also increasing, which brings a certain degree of challenge to video transmission. At present, each pixel of video in HDMI format contains at least four bytes. If chaos theory is used for encryption during transmission, the security of communication will be greatly improved. However, the real-time performance of transmission still needs to be improved. At present, people mainly use numerical simulation to study chaotic secure communication. C...
