> 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.

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.

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.

it’s the claim of it being a file system that’s throwing me. obviously nbd but maybe my mental models broken again.

		File system is the wrong word. What they should have used is file format. It is not wrong that you can have a file (bits and bytes encoded in the shape described by a file format) on some remote point. If you have an index of those files where you can programmatically choose between multiple files that could even pass as a crude "file system". But I doubt this is what they meant to refer to. It is likelier they wrongly assumed a file system is the system in which a file is organized, where in fact they meant file format.
