Talk:Telerecording

Merged with Kinescope ?

This has a big overlap with Kinescope. Suggest merging some of the info from that article but keeping the two separate as Kinescope was the preferred usage in America and Telerecording in the UK. Lee M 18:29, 9 Jun 2004 (UTC)

Examples of Telerecording?

Would it be a good idea to give some examples of telerecorded shows that are still broadcasted today, or available on video? Though there doesn't seem to be a lot shown any more, the earlier pre-colour episodes of Steptoe & Son are still regularly shown on UK Gold, and Hancock's Half Hour is still occasionally shown on BBC2. Are there any others? --Zilog Jones 00:34, 25 Apr 2005 (UTC)

Difficulty overstated

The comments "The time taken physically to move the film ... is much longer than the vertical blanking interval" and "It is not possible to accelerate the film fast enough" overstate the difficulty. The Marconi 'fast pulldown' film recorders (used for example by the BBC) managed to advance the film in about 1.8 milliseconds, fast enough to record both fields with the loss of only about 6 lines at the top and bottom of the picture.

It was true at first. The Marconi 'fast pulldown' film recorders did overcome the difficulty, but that technique was not developed until well into the kinescope era. The problem (with the Wikipedia article) could probably be resolved by modifying the sentence in question to say that at first the film could not be accelerated fast enough and special techniques were used to work around that limitation. With the development of the Marconi fast pulldown mechanism, that limitation was finally eliminated.

I noticed that this omission occurs in both the Wikipedia articles on Telerecording and Kinescope.
