I don't know if you saw it but the slingbox will disappear: https://www.slingbox.com/discontinued
I am already looking for a replacement solution to be able to change channels on any cable or satellite receiver. (with the correct remote control codes of course)
To see the tv remotely I already use something like that:

For the change of channels I am looking for something that could be controlled by computer and not with an app on a phone.
If anyone has an idea of the existing material to use or an assembly to do with a raspberry pi or something else...
Thank you
