Sky reveals HDTV launch lineup

I don't know what broadcasts there have been, but plenty of programmes have
been made in various high definition formats, two that spring to mind being
1250/50 and 1125/60. I've been seeing them at IBC on and off for many years,
and the exhibitors often have lists of programmes and feature films that have
used their equipment. It's not new. There were even high definition Plumbicon
tube cameras which gave absolutely stunning pictures at the exhibitions,
though I did wonder how well they would fare in typical daily broadcast use.
I think broadcasters quite often make programmes in new formats
experimentally but downconvert them for normal broadcast.

Zeiss calendar advertising their own involvement. It has stunning shots of
the earth and moon, including the famous "Earth Rise Over The Moon", and
Apollo space craft.

You could buy the "Earthrise" picture as a poster at the time (possibly still
can), and I had one on the wall in the London flat I lived in at the time. I
find it difficult to think of any other single image I've ever seen that has had
such an impact.

But you cannot compare what was used in the "lab" or niche markets to what
is used en masse for public broadcasting.
The public have not be used to HD for twenty years. As such, it will be a
major step forward in quality for them

Maybe. Which reminds me that the moon landing broadcasts that went out on
BBC1
would only have been on 405 lines, and I think BBC2 was officially still
monochrome until the following Christmas or New Year.



Although I'm pretty certain that BBC2 showed a reasonable amount of colour
in the late Sixties. The old whisky addled brain is long past its memory
peak, but I do seem to recall watching a fair number of imported American
'color' programmes, such as Rowan and Martin's laugh in.. My world and
welcome to it.. Wait till your father gets home.. Hondo etc.
Also IIRC didn't the BBC receive a fair amount of flak, because they chose
to make the Forsyth Saga in black-and-white, at a time when the BBC was
actually transmitting programmes in colour!

Sure you can get CRT HDTVs, both direct view and projection.
However, the projection ones are going the way of dinosaurs, and
the larger direct view ones seldom have real, true, pixel-perfect HD
resolution, at least at brightness you would use in a room with any
light on at all.

The current mainstays of HDTV are LCD (both projection, three chips,
and direct view), DLP, various forms of LCOS, and plasma. I suspect that
in smaller sizes CRT will remain popular for quite a while, albeit at
somewhat less than "true" HD resolution for large ones.

It was the last big production in black and white. I don't know the reason
for this, but in 1967 the first production studios to be converted to colour,
TC6, 7 and 8, would be just being completed and tested, so maybe the BBC
didn't think they were ready to undertake something of this size. There's a
big difference between transmitting films from a telecine machine or chat
programmes from a presentation studio and creating a major multipart drama,
particularly if the technology is new and you're not sure of it.

Yes, if they choose something like 1125/60 (1080 active lines) it will be a
major step forward to the picture resolution that is available today on some
mobile phones.

And whatever technical quality can be achieved by the system, every other
programme producer will probably degrade it in an attempt to make it look
like cine film.

Colour my life

Although limited colour transmissions had started on BBC-2 from 1967,
with the channel already on UHF and 625-lines, the main dawning of the
colour TV age in Britain came in November 1969, when the colour
service started on BBC-1 and ITV, initially in the major English regions.

The myth of Forsyth Saga being commissioned in Black and White
when BBC was transmitting in colour arose when it was retransmitted!

It was not until this program that the genre was proven
and more money made available for similar projects!
