From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux compatible DVB-S/T/C hardware that works with ubuntu kernels without recompilation (reddthat.com)

I couldn't find a r/linuxhardware alternative community, so I decided to ask here.

I have a TBS5530 DVB-S/T/C USB device and I am not happy with it due to https://github.com/tbsdtv/linux_media/issues/193

I don't want to recompile kernel or use out-of-tree media_builds everytime I upgrade my kernel (ubuntu22.04).

Therefore I am looking for a device that has built-in kernel driver or simply loadable one with apt install linux-modules-XXX .

I prefer USB devices since I use it with both my desktop & laptop.

Does anyone know such hardware available to buy ?

Note to myself: seems I am 175th subscriber and this is my 1st post. yay !

Only for DVB-T which is already offline in some countries.

Thanks, I know very little about how DVB works but that makes sense. What is the limitations for DVB-S/C ?

[–] M_Reimer@lemmy.world 3 points 1 year ago (1 children)

I'm pretty sure there are many more differences between DVB-T and DVB-S/C, but an obvious one is that DVB-S requires a back channel to the LNB which would be missing. The tuner has to be able to communicate which polarisation and frequency level is needed. The LNB will then make the required selection.

Cool, I stopped being lazy and looked up the DVB standards. TIL: a bit about digital broadcast transport methods.
