The continuous development of the media has drawn it closer to sports, and television broadcasting is an important facilitator in making sports events widely popular among people.The sports of table tennis require the use of a small court and a small ball played in a fast speed with strong rotation and variable landing points. These characteristics also lead to some limitations, which may greatly reduce audiences’ sense of immersion, experience and participation in events; and the screen design of television broadcast becomes very important. Therefore, this study takes the 2022 National Intercollegiate Athletic Games as a case study to analyze its broadcast screen design, hoping to provide suggestions on the screen design for similar sports events broadcasted in the future.","PeriodicalId":46240,"journal":{"name":"IET Networks","volume":"5 1","pages":"1-2"},"PeriodicalIF":1.4,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80546331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the actual conditions of the displacement and external force boundary conditions, the appropriate contact parameters, test the ideal convergence of the solution, obtain reasonable results, and estimate the motor performance curve of revolution speed and torque. In the ultrasonic motor prototyping of measurement characteristics, the use of piezoelectric induction, the size of the control voltage applied to the rotor pre-stressing to replace the traditional compression spring caused by uneven force of the rotor phenomenon, to avoid affecting the motor performance.

Neural networks have been continuously deepened to improve the accuracy of detection, so that the parameters have increased with a direct proportional rate. In this way, however, high energy consumption has been induced which obstacles the deployment of AI algorithms on portable devices. Therefore, the design of neural network must consider not only detection accuracy but also energy efficiency. In this paper, we analyzed energy consumption, detection accuracy and execution speed of our neural network model as well as the state-of-the-art models based on an FPGA platform called ZCU-102. We adopt the performance index from Low Power Computer Vision (LPCV) challenge which considers power dissipation, mean Average Precision (mAP) and Frames Per Second (FPS) at the same time to evaluate these models in an overall point of view. Agilev4 can achieve 59.9% of mAP@50 on MS COCO test-dev2017 datasets. If the input frame resolution is turned into $416times 416$, the processing frame rate can reach 20.7 FPS on ZCU-102.
