- 概要
- This paper describes a support mechanism for the sport of Ski Jumping which comprises a video feedback system. In this system, once recorded, the videos (10MB each) were stored in the Eye-Fi card, which is an SD card that is compatible with Wi-Fi communication. The videos were automatically transferred to the coach's computer. Once transferred, the videos were detected and compressed by the JISS Encoder. As a result, the sizes of the video files were reduced (3MB each). The compressed video files were then uploaded to Dropbox using a mobile hotspot connection. Then, they were automatically downloaded to the athlete's computer, where they were played using the GOM Player. When multiple athletes wanted to watch the videos simultaneously, the videos were delivered using the Air Video Server to each of them. The athletes were then able to watch the videos on their tablets. In this video feedback system, a 10-second video was transferred to the athlete's computer in about 40 seconds. The Japanese women's national Ski Jumping team and the national Nordic Combined team used this system for 550 days and transferred 24,081 video files in the 4 years between the XXII Olympic Winter Games in Sochi and the end of the 2017-2018 season.
