Subtitle Extraction and Sync Control System of Video Learning Contents using Smith-Waterman Algorithm

摘要

The present invention relates to a system for subtitle extraction and sync control of video learning content using the Smith-Waterman algorithm for learning video media for adolescents with hearing impairments. In more detail, when adolescents with hearing impairments learn through video media, if the synchronization between the video and the subtitle according to the network and the learner's terminal environment does not match, the location of the voice of the video converted to text and the subtitle text that matches the video By using the Smith-Waterman algorithm, the time difference between subtitles and video audio is adjusted to automatically adjust the sync, allowing audio and video media to be learned, facilitating various media education for hearing impaired teenagers and welfare for the disabled. It relates to a subtitle extraction and sync control system of video learning contents using the Smith-Waterman algorithm for video media learning of adolescents with hearing impairments contributing to this.
