Probably.
I usually use
tar -zcvf my_archive.tgz /xx/yyy/*
The 'v' list what it does, including filenames
You could probably use
tar -zcvf my_archive.tgz /xx/yyy/* 2>my_archive_contents.txt
to get a plain text content file, and save it with the archive.
Ultimately YOU decide how you compress / store. encrypt, whatever.
US launch codes are all zeros I've read as in a stress situation those poor guys cannot
remember anything more complicated, so something like Kamalatypezerozerozero.txt would be a good compression example.

So the .ts contains video in mpeg2 format (so compressed) and several audio channels in mp2 (so also compressed) format.
There seems to be new audio and video compression methods every few years...
