alt Hacker News> Satellite TV uses a file system called an MPEG transport stream that allows multiple audio, video, or data layers to be packaged into a single stream file.
Interesting read but that part really made me question my own sanity. It’s probably just lost in translation.

that's how it works. point a free-to-air dish at the right place in the sky, demodulate the DVB-S2 signal, and it's often IP traffic moving through mpeg transport streams.

I wouldn't describe Transport Stream as a "file system" but most people probably aren't familiar with the term multiplexing. It's true if you record a TS (e.g. to a .ts file) you can later split out the different Program Streams which can hold pretty much anything.
