I used VLC media player on Ubuntu Mate ARM64.
The generic USB web cam works perfectly.
I then tried the generic USB DVB-T stick bought years ago (Ireland is all H.264 DVB-T for HD and SD). I needed a hub or extension cable because the Pi is too small and cramped.
Capture Device -> Digital TV -> DVB-T. Enter a mux in KHz and set BW to 8 MHz (maybe auto works)
Program guide under Tools works.
Use Playback -> Program menu to select a station. The HD stutters a lot on RTE1 HD, so I selected a Virgin channel (cheapskates). It plays usably. My TCL Nxtpaper11 tablet is however flawless with HD DVB-T.
I've no analogue/composite video capture apart from Digital8 camcorder, ISA MJPEG video editing card with HW overlay and also analogue out and some PCI cards inc Analogue TV tuner that were never good.
Likely any generic USB capture device will look like a web cam to Linux and work on Pi.
I was thinking of getting a couple of USB capture devices anyway, so I may buy 1 or more of these:
HDMI Capture (SD, HD and 4K exist).

https://www.amazon.de/-/en/dp/B0B7DSPPNX/
Also they may not decrypt HDCP.
I already have a variety of analogue to HDMI encoders (One Component model only converts progressive! But PAL and NTSC DVDs work) for composite, Y/C, component and VGA because newer TVs are HDMI only. My old 40" Toshiba HDTV does everything (4 x HDMI, composite, Y/C, component any format, and VGA).
Analogue (loads of brands of this generic device supposedly NTSC/PAL/SECAM and composite or Y/C.

This will work with anything that can display streaming video:

Or get a Pi camera board and point it at an existing screen. Arr me hearties!
Also I can convert DVB-T to PAL composite or RGB with a cheap setbox. The Technomate HDMI DVB-T modulator V4 seems to work OK. However using mouse on desktop shown on a TV via DTT has rather severe latency, rubber band effect. Also there is no TV in library. I use an old 4:3 LCD that can only work with 720p60 on a setbox. The setbox "forgets" that HDMI mode on reboot, but amazingly the remote has a vmode button and it cycles through the modes putting partial setting on LED 7 segment channel display (720p50 and 720p60 are shown as 720p). It's amazing how well frame rate conversion and de-interlacing works these days.
