Depending on the actual demand of maritime security, this paper analyzes the specific requirements of video encryption algorithm for maritime monitoring system. Based on the technology of Internet of things, the intelligent monitoring system of unmanned surface vessels (USV) is designed and realized, and the security technology and network technology of the Internet of things are adopted. The USV are utilized to monitor and collect information on the sea, which is critical to maritime security. Once the video data were captured by pirates and criminals during the transmission, the security of the sea will be affected awfully. The shortcomings of traditional algorithms are as follows: the encryption degree is not high, computing cost is expensive, and video data is intercepted and captured easily during the transmission process. In order to overcome the disadvantages, a novel encryption algorithm, i.e., the improved Hill encryption algorithm, is proposed to deal with the security problems of the unmanned video monitoring system in this paper. Specifically, the Hill algorithm of classical cryptography is transplanted into image encryption, using an invertible matrix as the key to realize the encryption of image matrix. The improved Hill encryption algorithm combines with the process of video compression and regulates the parameters of the encryption process according to the content of the video image and overcomes the disadvantages that exist in the traditional encryption algorithm and decreases the computation time of the inverse matrix so that the comprehensive performance of the algorithm is optimal with different image information. Experiments results validate the favorable performance of the proposed improved encryption algorithm.

Nowadays, the development and innovation of tennis have basically been integrated with the Internet, and the penetration of big data is accelerating the development of tennis. Collect data and statistics about tennis matches, analyze the key winning factors of the game, assign players’ gains and losses, and assign points. Fully understand the game’s tactics and various key technical functions of the player and enhance the influence of the game’s attention. Therefore, as the era of the Internet of Things is about to come, the development of sports events in my country should seize the opportunity of innovation in the application of Internet of Things technology, accelerate the process of upgrading informatization and intelligence, and achieve leapfrog development. This article is aimed at studying the use of the Internet of Things security technology, research, and design a monitoring system for the key technical characteristics of male tennis players. This paper proposes to develop a novel real-time video semantic analysis prototype system for tennis matches, taking the video from the monitoring perspective of tennis matches as the analysis object. The experimental results in this article show that from Wimbledon to the Australian Open, the Australian Open is very slow, and finally, to the French Open, the speed of the ball slows down and improves the accuracy of the tennis crisis system. The average level and the correct answer rate are 61.37%. Eventually, it rose from the highest 86.13% to 86.92%, and the highest was the lowest. It seems that a monitoring system for the basic technical characteristics of male tennis players is more feasible.

Electric power automation system can also be called telecontrol system, while video monitoring technology is one of the key of video compression and coding technology. In view of the actual situation of video signal remote transmission, high compression rate and good quality standard should be considered and chosen in priority. This paper analyzes the h.264 standard code rate control method and proposes jump frame judgment criterion based on MAD ratio. Furthermore, it elaborates the contrast test results between the jump frame algorithm and the previous algorithm. Telecontrol video monitoring system should be based on digital video recorder optimization (DVR) design and video monitoring system integrated communication design, which can guarantee the transmission quality of electric power remote data and video data. This paper discusses the main functions of the video management system and the design scheme of the software system.

: Cloud monitoring technology is an important maintenance and management tool for cloud platforms.Cloud monitoring system is a kind of network monitoring service, monitoring technology and monitoring platform based on Internet. At present, the monitoring system is changed from the local monitoring to cloud monitoring, with the flexibility and convenience improved, but also exposed more security issues. Cloud video may be intercepted or changed in the transmission process. Most of the existing encryption algorithms have defects in real-time and security. Aiming at the current security problems of cloud video surveillance, this paper proposes a new video encryption algorithm based on H.264 standard. By using the advanced FMO mechanism, the related macro blocks can be driven into different Slice. The encryption algorithm proposed in this paper can encrypt the whole video content by encrypting the FMO sub images. The method has high real-time performance, and the encryption process can be executed in parallel with the coding process. The algorithm can also be combined with traditional scrambling algorithm, further improve the video encryption effect. The algorithm selects the encrypted part of the video data, which reducing the amount of data to be encrypted. Thus reducing the computational complexity of the encryption system, with faster encryption speed, improve real-time and security, suitable for transfer through mobile multimedia and wireless multimedia network.
