Checked all my manuals, but it was not mentioned. I think it's just
VGA (640×480, 256 colours) and nothing else. The manuals only talk
about connecting it to VGA monitors, nothing about TV signals
mentioned anywhere. It is a 24 channel audio recording device (from
2001…) so I don't think they spent too much time designing the VGA
output… There is a built in display (320×240, 2 colours), and the unit
is designed to use it, rather than an external monitor. The VGA output
was originally just a nice bonus… (before they upgraded the internal
software to 2.0, the external monitor was for viewing only, you could
still only work with the built in display. 2.0 meant that you could
suddenly work directly on a VGA monitor).

Yes, I wrote in my first post that I ”have searched a bit”, so I was
just talking about your hints about what to search for.
