Re: BBC4 to recreate the first night of television.
True, but I think that they could have expanded things a bit more by, say, making part one about the start of live TV broadcasts and then maybe a couple of more episodes.

Re: BBC4 to recreate the first night of television.
If they had that as a plan I am sure they would have but they were simply celebrating the anniversary of the first live broadcast and to me they did their job well.

Re: BBC4 to recreate the first night of television.
Yes, I also found it to be very informing as well as enjoyable.

It was the classic example of a technological blind alley, complete with complex workarounds to cover shortcomings that ought really to have killed it off long before opening night. I'm probably going to watch The Fools on the Hill again now just to be sure, but I don't recall them really going into the reason Baird's system got the gig, and how it survived for even half its contracted six month trial. Even last night Dallas Campbell skimmed over it with a one-line reference to Baird's personal influence in having pushed for development of a TV service in the first place. Of course the system was so utterly impractical that BBC4 couldn't actually recreate it at all. A 3ft diameter disc spinning at 6,000rpm in a vacuum chamber ... a massive machine to process film stock and deliver it to another Baird camera in time to delay the "live" broadcast by a mere 54 seconds ... beyond the budget of a single documentary and doubtless ruinously expensive back in 1936 too. Absolutely fascinating though. |
Re: BBC4 to recreate the first night of television.
I couldn't believe how big and expensive and really impractical Baird's system was and even that early TV sets had a switch to change between the two systems, it really was experimental and a real shame that no real documentation exists in regards to the machine.
Imagine if that system did in some other reality win, then TV as we know it would not be here. Still as you say very fascinating. |

After a bit of research I found this after someone asked what we were thinking: 'We still use mechanical TV systems. Blu Ray, DVD and VHS are all mechanical systems involving motors, even PVRs have mechanical parts. The Apollo Television and early Space Shuttle TV used a version of the Baird sequential system which later went on to DLP with rear screen projection TV's using the Baird colour filter wheel as late as the 1990s'. |
Re: BBC4 to recreate the first night of television.
Don't think you can really call hard drives and disc drives the same thing though. They maybe mechanical in terms of moving parts but they still require electricity to work.

It is an interesting point though, think how many people disposed of their old VHF TV's after BBC2 UHF started, their monochrome TV's after colour started and their CRT TV's after DSO believing them to be worthless? If it weren't for the odd person keeping them, there would be none available for historical TV enthusiasts to pursue their hobby and we would be historically poorer. What was regarded as rubbish is now worth money again all these years later! |

Re: BBC4 to recreate the first night of television.
It might be worth something to a collector, even if it doesn't work.
If you don't want to sell it, I'd definitely hang onto it after all this time. |

Re: BBC4 to recreate the first night of television.
A hard drive has moving parts - a HDD uses magnetism to store data on a rotating platter, and the read/write head floats above the spinning platter reading and writing data.
If it didn't have moving parts, it wouldn't work. Unless, of course, it's a SSD (Solid State Drive)... |
