Widescreen 405 ?

Hi People,

This may be an amazingly stupid question but, if i buy an Aurora converter (or any other for that matter) and feed it video from a DVD player for instance, and the film is in the wide screen format, what will i see on my Bush TV12AM?
Will the picture be truncated like the old wide screen films shown on non wide screen tv's or will i get a letterbox version of the picture (on a 9" screen - excellant !!).
Interested to know,
Cheers Alan.

Hi Alan,

You'd get whatever you've set the DVD player up for, basically. The DVD player should be set up for a 4:3 TV set, then you should be able to select between 4:3 "pan and scan" mode or 16:9 "letterbox" depending on what the DVD itself and the player allow. Some DVDs don't have the option of 4:3 "pan and scan"; but some DVD players may allow the centre 4:3 section of the image to be zoomed to full-screen . Of course with no panning information you might miss some action off-screen.

Regards, Kat

Re: Widescreen 405 ?

Thanks for clearing that up Kat,

I was'nt sure what the convertor would do with the 'Extra' information being put through.
Do you have any thoughts on releasing your software for your PC convertor on a cd so that other people can try it out. I use a pc daily, but have never used Linux, so having a handy ready to go (well almost) system on disk would be great.
All the Best,
Alan.

The short answer is "nothing"...

If the DVD player's set up for a "letterbox" picture on a 4:3 625-line set, that's what you get after it's passed through the converter.

Likewise, if you tell the DVD player it's connected to a widescreen set (so you'd see a correct picture on a 16:9 set but a horizontally squashed picture on a 4:3 set) you'd get a horizontally squashed picture on the 405-line set.

Drifting a tad OT for this thread; but yes, that is part of the Grand Plan; but putting together a bootable "Live CD" Linux distro is non-trivial. But, fairly soon I'll have full instructions on the website for installing KnoppMyth then modifying it for 405-line; it's not that difficult.

Dragging things back on topic again; the various bits of PC software for playing recordings/DVD/etc have a variety of options for zooming/resizing pictures in various ways. Some who saw the demo at the NVCF may remember me zooming the hard disk recordings of Doctor Who (widescreen from digital terrestrial) to 4:3 as letterboxed widescreen on a 9" set just doesn't work too well

Alan,
For the Aurora converters, there are two possibilities. The low cost converter does not do any aspect ratio correction or cropping. The multi-standard unit has a Zoom function which will crop the center 4:3 section out of a 16:9 source. Since so much material today, both broadcast and DVD, is in letterbox format, this allows you to fill the screen on these early, small screen sets.

Take care,
Darryl

I find on the Dinosaur converter this displays images exactly the same as displayed on a 625-line set but in 405-line B&W of course.

On the cheap Freeview boxes sold by Asda one can, at a touch of a button, adjust the size of the image on a Widescreen transmission allowing for 16:3 (true full widescreen), false widescreen (ie:identical to terrestial transmissions with a gap at the top and bottom) and expanded which fills the entire screen.

A VCR, DVD Recorder or 625-405 standards converter records/displays what's seen via the Freeview Box.

The Freeview box can be adjusted to give w/s which will be displayed as a squashed horizontally image on a conventional set, but full widescreen on a w/s set. Better shut up before I go off topic!

Anyway the main advantage to me personally is I find "Fake widescreen" as txd on terrestial TV unacceptable when converted to 405-lines. At least one can expand the image on a Freeview box to fill the entire screen.
