Re: Downloadable Test Card DVD
 

Thanks Mike.

Finally got round to downloading some freeware to enable me to burn it to a dvd and it works very well indeed:)

Many thanks Mike, Just burnt a disk, will make a nice addition to my collection especialy as I am just old enough to remember Sylvia Peters. It did look a little different on the Bush TV11A.

Re: Downloadable Test Card DVD
 

Thanks Andi, Mal, Trevor, Tas, Victor and Craig. I'm glad it's a useful thing. The only minor problem with putting test cards on DVD is that a lot of machines cut off the sides so sometimes you don't get any (or reduced) edge castellations.

Kind regards.

From Mike.

Re: Downloadable Test Card DVD
 

Mike, as a newcomer to this forum (but as a long-ago lapsed member of the trade) may I also add my thanks to you for this excellent resource.

A few questions/points for you: can you please explain the resoultion difference between the two Test Card F versions, one of which is showing a BBC identifier, and the other which is showing your SWETV museum? Presumably the museum version is a direct digital creation, rather than a screen-grab for the BBC version?

Would you have any plans to add to content of this disk? May I place with you some Viewers' Requests? A high-res BBC recreated Test Card F would be great, as would a PM5544 card, and also a dot/spot convergence signal.

Is there a mechanism via which I can make an appropriate donation to your museum?

All best

echelon

Hi Echelon.

My apologies for not replying sooner - I only just noticed that there was a reply. :)

Just a quick note about TCF and TCJ - Test card F was the original George-Hersee designed version from 1967 which was simply filmed off a card by a normal TV camera. The TCJ was a much later all-electronic version with a few differences - a slightly bigger circle, a slightly zoomed out picture of Carol and Bubbles and a few other bits and bobs.

There is now a new version (see below) which has the PM5544 card and a few other bits and bobs which have been tidied up from the previous version. I may well put a few things on in future version - certainly the cross-hatch wants modifying a bit and I may add dots too. Also a "next" / "prev" option too, but that means doing a bit of programming, which sounds complicated.

Thanks Echelon.

Kind regards.

From Mike.

Hi all.

A new version of the Test Card Disc is now available (V0.15).

This new disc has an added PM5544 test card, a modified (and nicer) version of Test Card F with the "BBC2 Colour" caption. A few other bits and pieces have also been tidied up etc. As always, you just need to use some kind of DVD-burning software to turn the image file into a proper DVD.

Anyway, here it is:

Enjoy. :)

Thanks all.

Kind regards.

From Mike.

Re: Downloadable Test Card DVD
 

Hello Mike,

No, it wasn't. It was a transparency that was used. It consisted of two transparencies sandwiched together, one for the monochrome part of TCF and one for the colour part. An electronic version was introduced in 1984.

See this web site page:

http://www.barney-wol.net/video/test...testcardf.html

The difference in the size of the circles is only about 2 pixels and wouldn't be noticeable except by direct comparison. TCJ was introduced in 1999.

See this web page:

http://www.barney-wol.net/video/test...testcardj.html

Regards,

Dave.

Re: Downloadable Test Card DVD
 

I stand corrected Dave. :)

The main point I was trying to make was that it was a mechanical device whereas Test Card J was all-electronic. I'm not any kind of expert (as you can tell) but Echelon was asking for the main difference between the two test cards.

Re: Downloadable Test Card DVD
 

Hello Mike,

Whilst that is true, one shouldn't make untrue statements (which, I'm sure, was not your intention) as they are likely to be taken as fact and repeated elsewhere, propagating the untruth until it is difficult to rebut!

I hope you found the links I gave of some interest.

Regards,

Dave, G8TVW.

Re: Downloadable Test Card DVD
 

I believe that one other difference was that the cross on the blackboard was repositioned at the centre of the testcard to give more accurate static convergence - something overlooked in the original.

Re: Downloadable Test Card DVD
 

Hi Mike.

Many thanks for the test card iso files. It took me a little while to work out how to use the free ImgBurn software required for converting the iso files to a useable DVD but the result is excellent.
Very useful test patterns, particularly Test Card G for colour decoder assessment.
I also like Test Card J, a revamped Test Card F. The main visual difference between these two cards is that on TCJ the centre picture appears a zoomed out version of TCF. Also, the images of the girl and the clown appear slightly darker on TCJ.

Regards
Symon.

Re: Downloadable Test Card DVD
 

A big thanks from me also Mike! Great quality and will be super with the old tellies. John.

Re: Downloadable Test Card DVD

In addition to what was on the old disc, the new disc contains a newly recreated version of the original 5:4 Test Card C as well as a slight modification to Test Card J and a new 1950s BBC Tuning Signal.

Thanks everyone.
