That shows you are not tuning any muxes.
If you are in Germany - then the predefined lists in TV Headend may well be out of date and refer back to the old German SD MPEG2 DVB-T system.
Germany has migrated (or is in the process of migrating) to DVB-T2 (using HD HEVC/H265) and will need new mux information potentially. It's entirely possible the frequency database in TV Headend is still putting in the muxes for the old German SD standard.
What TV transmitter do you receive your TV from? I might be able to google to assist you with the correct settings for TV Headend.
I always configure my TV Headend installs manually from a frequency list, rather than using the wizard. It's a bit more involved, but once you master it you have a much better understanding of how TV Headend, and DVB-T/T2, works.
TV Headend has the concept of Networks. These are different TV sources. For a single DVB-T/T2 tuner you probably just want a single Network. (In the UK I call mine Freeview HD. You might want to call yours DVB-T2 or Freenet or something)
Each adaptor is associated with one or more networks. This is how TV Headend knows which TV adaptor to use for each network.
You then add muxes to the Network. A mux is a DVB-T/T2 broadcast on a single frequency that can carry multiple TV, Radio, Text etc. services. The Mux information needed will be as a minimum the frequency, whether the mux is DVB-T or DVB-T2, and the bandwidth of the mux (I think Germany uses
7MHz muxes, whereas the UK uses 8MHz) You may be able to leave the other settings on AUTO, or you may also need to enter the Constellation (which in Germany on DVB-T2 is
64QAM) and the Transmission Mode (Which in Germany on DVB-T2 is either
16k carriers or
32k carriers. It seems to vary by region for the ARD and ZDF muxes). I've never had to enter manual details for Guard Interval or FEC/Hierarchy.
I guess in Germany you will add an ARD Mux, a ZDF Mux, and probably a regional Mux? The 3 Freenet muxes carrying Sat 1, Pro 7 etc. are all encrypted (which means they aren't going to be receivable with just a Pi and a TV uHAT) - and the only free services the 3 Freenet muxes carry are Shopping and Religion?
Once these 3 muxes have scanned you will have services in the Services tab, but these won't be mapped to channels. You need to then click on the Map Services Dropdown. This will then associate a Service with a Channel. In Germany I think you use an EIT DVB EPG so the default EPG grabber should just work.
IF you are using Kodi (which on a Pi for TV Viewing which may be an issue for 1080p50 HEVC - which is the standard used for most German DVB-T2) then you might also want to enable the option to use the channel numbers from the backend in the Live TV and PVR settings menus in Kodi. This will mean your channels in Kodi map to the channel numbers used by the broadcasters.
