PAL Teletext subtitles extraction

[boulder]

I 'm currently developing a small program that will allow me to rip PAL TeleText subtitles from a DVR-MS file.
It seems feasible, I can decypher 99.99% of the text, and some of the colour codes.

Don't expect anything fancy, though.
What I 'm working on is a command line utility, which will take as an input the dumpfile you get when you dump the data from pin 2, and which will produce an SRT file with the timings and subtitles.
SRT does not support colours though, so the colour information will certainly not be there.
Also, accented characters will not be supported.
And finally, I am not sure yet whether timings will be precise enough, etc.

Anyway, I feel I 've gotten quite far already, I can already get an SRT file, but it contains the broadcast times of the subtitles, instead of the relative file values.

I was wondering if anyone else would be interested in such a utility.

The reason I started this whole thing is because I could not play back DVR-MS files on a second PC that does not have Mediacenter on it, without losing the subtitles.

BTW : Teletext subtitles, once a recording has been made, are not stored in the VBI anymore.
Instead, they have been moved, along with all other Teletext pages to a separate stream (pin 2).

You might want to check out CCExtractor written by Carlos in Spain. I know it handles NTSC .ts but given where he is he might have done PAL too. Its on Sourceforge.

Hmm, I doubt it.
PAL and NTSC are totally different when it comes to closed captions/subtitles.
PAL uses Teletext, uses colours, can have up to 3 lines, and has all kinds of advanced features.

Why would he do PAL and not release it to the public, and do it for NTSC ?

Anyway, I have released my own version now, and called it TTSubripper.

Hi

I'm deaf and I like to capture subtitles teletext but almost impossible too difficult and too much work.... I find easy is use digital box link S-VIDEO to PC TUNER and record mpeg and already copy telext init 'burn' into mpeg file then I use VIDEOREDO to remove ads and then to NERO 7 burn for DVD. Subtitles teletext will be always show.

Ahh way simple.


Anyway do you know how to simple rip CC into SUBTITLES TELEXT ? because I have import DVD from USA that with CC and do not work in my DVD player

I'm from Australia

Thanks

Well, of course I don't think what I wrote is too much work to use, it 's a pity that you won't even give it a try.

I can understand that for you that is ideal, for me, it 's just what I don't want of course, I 'm not deaf nor hard of hearing, I 'm just using the subtitles to make sure I understand every word being said, that 's all.

From a forum on Videohelp.com :

I've got a private message asking me how I did it, so, here's how, it's very easy:

1- Launch the VobSub Ripper Wizard. Click the Load IFO button and browse to the IFO file you copied. Then click the Save To button and select the directory to store the captions in, then click Next.

2 - You will now see a dialog screen to select which streams you wish to process. By default, everything will be selected. If you don't want the DVD's subtitles, unselect everything. A checkbox controls whether the closed captions will be extracted. If it is unchecked when the dialog first appears, this probably means that the tool cannot find any captions.

3 - Click on the Next button to start the extract process. The speed of this depends on the speed of your DVD drive.

4 - If you go to the directory you selected in Step 1, you will see a few files, the one that has the ripped captions is VTS_01_0.cc.srt (assuming you ripped VTS_01).

That's it! Open that file with a program like Subtitle Workshop and do whatever you want to it! :wink:"

I still exist
Yes, it works with XP and other OS'es, you need to run it from a command prompt.
I 'm not that into graphical programming.
First you need a dump file.
Actually everything you need is explained on the website.
It should work with WTV files as well.
