LingvoTV Chrome Extension is a small program you can only install on a
Chrome Browser on a desktop computer. It will grab subtitles appearing
on the screen as you watch the movie and send them to LingvoTV Web App.
It is required to install it because otherwise, LingvoTV Web App won't
receive subtitles.
Open
LingvoTV site on a desktop Chrome
Browser, click on the "Chrome Extension" button, and it will take you to
the official Chrome Web Store, then click on "Add to Chrome" to install.
