Back in 1952 there was no clearcut route to recording video on magnetic tape, it was very much a research problem. Quadruplex machines worked, but were VERY expensive. This cost may have been acceptable to US networks with their timezone problems but was a deterrent to European broadcasters. Had some form of linear recording worked, it would likely have been quite a bit less expensive to build though the tape costs would have been high. I suspect this was the reason why the BBC pursued VERA until 1958. It would be hard to find the total R&D costs for either Quadruplex or VERA. From what I know of the BBC Research labs the amount of expenditure would have been pretty small. A barely measureable fraction of the BBC's total budget. If you want a different comparison, look at standards conversion. BBC Research and Designs departments produced the world's first all electronic standards converters between 525/60 and 625/50. They did it in time for the 1968 Mexico olympics where it was urgently needed. I don't know if there was any work at all in the US on this subject. |

Haven't got the exact date to hand but prior to c1963 all conversion was optical. In other words a camera pointed at a monitor. Not very satisfactory but the best that could be done at the time. Even worse if you try to do it in colour. The only other method wasn't real time. It was to telerecord on film, then telecine on the output standard. Not really an improvement on optical conversion.
c1963 the BBC developed the world's first linestore converter. This used analogue methods to store a whole line of video. It was used primarily for 625>405 conversion. In principle this method could be used for any pair of standards that share the same field rate. This design was the basis of the analogue fieldstore converter that was first deployed in 1968. Hence in answer to your question, the early US<>Europe satellie links used optical conversion. |

Collectivism to the "rescue": Enter BBC - funded by $6b/yr licensing tax. What do they do with all that money? Create Public Sector jobs. What do they do at these jobs? Keep working on a failed VTR project for 2 more years after Broadcast-Quality VTR available. |

I don't know about current figures but through the 1950s, 60s, 70s, 80s the BBC had a reputation for being able to produce programmes at a lower cost than its commercial rival in the UK. When will a US broadcaster stage a music festival that rivals the Proms? When will a US broadcaster run a mainstream radio channel that comes close to BBC Radio 4? Neither of these would be commercially viable but both add hugely to the quality of life over here. Burning, in the sense of keeping a candle dimly alight. I doubt if figures are readily available but BBC engineering research probably used less than 1% of the BBC's budget and VERA was some small fraction of that. To get some idea of the work done by BBC Research have a look at some of the reports http://www.bbc.co.uk/rd/publications/rdreports.shtml As with all research, some of it will have led up blind alleys while other work will turn out to be very useful. No real way to tell in advance. Last edited by ppppenguin; 01-31-2013 at 02:44 AM. |

This is a Regressive Tax that hits the Working Class the hardest (those least interested in BBC programming)
Meanwhile BBC refuses to reveal top salaries - though some are suspected of pulling $3,000,000/yr Hope those making $3,000,000 pay their $230 License (which goes right back in their pocket )This is why we have to keep fighting to eliminate remaining Govt subsidies to PBS Last edited by NewVista; 01-31-2013 at 10:10 AM. |
