I’ve found these very useful too. Eine Möhre für Zwei, a Sesame Street spinoff is very sweet too.

I’ve listened to the Easy German podcast off and on and enjoy their discussions.

Listening to German news radio (NDR Info, RBB InfoRadio, etc.) in the background has also helped.

For structure in learning, I’ve found the roadmap guide in https://refold.la/roadmap very helpful.

Something like a Telestar Digibit should do what you’re after. It’s a Sat>IP box that takes dvb-s and dvb-s2 transponders and pushes the transport streams over IP. From memory it’s UDP.

They take a bit of configuring, and there are some alternative firmware variants out there too that add more functionality.

I used one of these briefly a few years back and can’t remember all the details I’m afraid.
