I rarely watch broadcast television in any of its forms and when I do
it's usually German analogue (yes I speak German).

I don't speak German but sometimes watch their transport TV channel on the
internet - "Bahn TV". They have a great programme at 2330 (our time) where
they just clamp a camera on the front of a train and broadcast the entire
journey, usually an hour or so. It's completely mindless, but surprisingly
restful to watch. There is no commentary, no music, no camera moves, no
gimmicks whatsoever, just a brief scrolling caption telling the name of
each station as we approach. No, I'm not a train freak. It's just like
going on a journey and being able to watch the scenery because somebody
else is driving. It must cost only buttons to produce, so I wonder why
nobody else has thought of it.

3-sat used to do this with a road journey every night after closedown. I've
often thought about recording the output from the cameras on my van, as
evidence when some clot crashes into me.

Yes, but remember that archiving is still done on tape based systems [1], the

That seems odd - because if a programme was repeated at some point in
the future, it'd have to be recopied?

No, you only need to ingest the programme once. It then becomes a file, that
can be transferred back and forth between the playout server, and the 'deep'
archive storage ad-infinitum. Think of it like transferring an mp3 file from
your PC, to portable player. If you get bored with the track, you can erase it
from you player, but you'll still have it stored on the PC, without the need
to rip it from the original CD.

I don't think I've ever noticed an ARC artefact on analogue TV. Have you got a
screen shot to illustrate your point ? I've not seen in the 10 years I've
occupied these groups a single mention of such an effect (yours excepted).

What sort of thing are you looking for? In the case of 16:9FHA
converted to 14:9 and 16:9 letterbox, the artefacts would simply be a
loss of sharpness, due to the rescaling process, and an unnatural
tracking of movement, due to the deinterlace-reinterlace process.

Where do you get the idea the image is de/re interlaced ?

AIUI each field is treated in its own right.

You seemed to have missed my original point. Upconverted C4 SD, via the C4 HD
channel looks better than the same output as seen on analogue.

I was merely pointing out the reasons why it looks better - ie. the
shortcomings of the SD broadcast chains, most of which could be
avoided or improved upon if broadcasters cared.

I'm with you on that one. However there are so many opportunities for the
analogue tx chain to suffer degradation, that ARC and server artefacts are the
least of your worries IMHO.
