Precisely but it doesn't have to be remote. Some people self host locally but that requires a fast connection and a vpn. Most remote seedbox's are basically virtual private servers. They usually have apps like Jellyfin or plex for streaming all your content locally. Which is what I do and it's very automated and convenient. You can also use your seedbox as a vpn tunnel. If you're a member or interested in private torrent trackers, a seedbox is recommended to help keep your ratio high.
