Absolutely.

I see it as a more detailed data flow.

There are the authoring tools that create the captions in some format.

There are the transcoding tools that convert a given captions file
into a supported input format.

There are the encoding tools that map a supported input format into
the binary file, should that be necessary / requested. There could be
compression involved here.

Finally. there are the video players that need to extract the
encapsulated input format, interpret it, and display it to screen.

Cheers,
Silvia.
