Can we get a feature to indicate whether a Blu-ray or DVD in the Blu-ray.com database has line 21 (or similar PAL equivalent) closed captions or not by having a section that shows up on the release's page similar to how audio description tracks are displayed on this site?
I was curious after watching *this* Technology Connections video about closed captions recently.
There are also early Blu-rays with line 21 closed captions like *Die Hard* and *Die Hard 2*.
Also, I'd suggest that the "Closed captioning" section be split by format whenever it is on a DVD but not Blu-ray, a Blu-ray but not DVD, on both, or on Blu-ray but not 4K, which never had line 21 closed captions to begin with due to its more modern nature, and also I don't think there's any 4K players with composite outputs.
