A Netflix multi-device subtitle generator for the elderly and visually impaired, a project I've been planning for a long time.

I removed the video for now because there might be copyright issues.
After subscribing to Netflix, I haven't touched the middle part. Since the series is so long and you have to watch subtitles to concentrate, if you enlarge the subtitles too much compared to the monitor, the screen also looks strange. Previously, I planned and briefly created a Chrome extension, a viewer that transmits from one system, but I adopted a method of syncing with a specific sound. It's inaudible to humans, but it synchronizes between systems using ultrasound, and if not, you can adjust the sync by specifying the time.

It's the age of learning Chinese characters, so let's study Mandarin and Chinese together. The initial idea was "What if I became like this?", and before I knew it, I became like that. I will also revise the stroke order practice for stroke patients.
