It's a small server built by Sundtek for their tuners to watch, stream and record LiveTV (e.g. without using TVHeadend).
You must have installed the Sundtek USB TV Driver (and a Sundtek tuner of course) for this program to run.
It provides a web interface on port 22000; there's also a 'sundtek_ss' command to control the daemon via SSH and update the application binary without the need to reinstall this meta-package.
