My requirement is much less demanding.
I only need to show test cards,static pictures and the like.
Whats most important is that the output is as close to the full PAL
standard as possible.
So to widen the scope the question becomes:
'Where can I get an old system that will do broadcast standard PAL TV
out.'
PAL will be gone as soon as the analog systems TV systems are switched
off and digital takes over.

Does anybody know which ones and could they do PAL or just NTSC?
Special effects makers strove for higher quality as the job demanded.
Part of the appeal of the Amiga for special effects was the price of the
32-bit hardware and software. SGI hardware and software was an order of
magnitude more expensive. NewTek's Lightwave was used by the Babylon 5
special effects group. I know they also used an early 3D Studio on a PC
for some of the modeling. (And they used some of my software to convert
between 3D file formats; as I recall, the spun shape of the original
station was made that way.)
Yes, the Amiga had the horsepower to play back animations of useful
color depths in real-time. Depending on the image and the requirements,
some special effects might even look OK with the straight TV-out. For
example, the typical synthetic "computer display" in a cheesy sci-fi
show. When you're filming an actor in front of an animation playing on
a monitor, low-res is OK.
More often for serious output, as in Babylon 5's case, they laid their
bitmaps to an 8mm Exabyte tape as data files, then imported into an
Abekas framebuffer that could play them back in real time.
High quality, no generational loss every time you made an edit or copy.
Straight TV-out wasn't a high-quality method of exporting video, though.
In the early days, some people used single-frame video recorders to lay
down a sequence of animation. This worked reasonably well, within NTSC
generational limits. Later, some NewTek Video Toaster-based animators
used its higher-quality framebuffer as the output to single-frame
recordings.
