I have many videos that contain closed captioning. I am trying to digitize these while preserving the closed captioning. I do not want them converted to subtitles. I use a TV guardian which is inserted between a video device and television. It decodes the closed captioning and filters the language based on settings I set up. Is there any way to convert video to mp4 (or some other format) and then be able to play it back from pc, through the Guardian and have the closed captioning data available? The guardian uses an analog rca interface in case it matters.

The TV guardian won't work if you are playing video using a PC. PC video connections can't provide closed caption data. You would need to play the videos with a hardware media player that has composite video out instead to have the right connection available. However, I don't know if any media players strip the part of the signal containing closed captions like some DVD players do.

That's what I was afraid of. I was hoping there was a way to transmit the cc data from a sound card but was afraid it wouldn't happen.
Along that line, I have considered dubbing it over after passing it through the Guardian but then I have to deal with copy protection issues. All I'm trying to do is store movies I already own on a media center to eliminate the need for using the actual disks/tapes. If anyone has any thoughts I'd like to hear them.
i dont know really but maybe you can convert to subtitles, and make up them like a closed captions, with some subtitle editor
you can also record them with one hvr 1600 or hvr 2250 cards of hauppagge , they can capture closed captions, via composite.
they give to you a .ts file that you can transcode to mp4 but files can be big.
I have an HVR 2250 which I have used with Windows Media Center. WMC can record analog closed captions from the HVR 2250's analog connections, but they aren't stored in the WTV file's MPEG-2 video stream the way some other capture devices provide them. They are stored in their own separate stream, and would have to be converted to subtitles. Setting up Widows Media Center for tape capture is possible, but it requires installing an IR receiver/IR blaster and a remote plus setting up WMC to record from a cable box. Most of those to whom I have suggested this method don't like the idea.

It sounds like it's all a moot point anyway. Based on the earlier post by usually quiet, a pc cannot output a cc data stream for the TV guardian to read. I can get cc data converted to subtitles using Handbrake but that doesn't help me output it to the TV guardian.
Analog closed captions are not used as much because HD video connections don't support the technology. Except for over-the-air broadcast TV (where the TV is also the decoding device), the responsibility for displaying closed captions has moved from TVs to whatever device decodes the digital video.
Since changes in the way we watch video has made your language filter obsolete, you will need to censor your videos manually, or be very selective about what you watch.
i attach one record of hvr 1600 with them.
you can see them with vlc.
you check help site of tv guardian already? why not contact them

Windows Media Center displayed CCs for the same TV program using the digital tuner. Since I can also capture closed captions using my ATI TV Wonder HD 600 USB's analog composite connection, it wasn't the set-top box I was using.
[Edit]I just tried WinTV 8 on the recording I made. It looks like the closed captions are present, but only WinTV can display them. CCExtractor 0.77 doesn't find them, nor can MediaInfo, nor can VLC.
It is all moot anyway, since the OP can't get closed captions in the signal from any common PC video connection.

hvr 2250 capture too , but only way to display - extract them , its using c.c extractor, you get a .srt file
The latest version of CCExtractor (downloaded from Source Forge today) did not find any closed captions in my recordings made with WinTV. This latest version of CCExtractor does find closed captions in other files that have them, so it appears WinTV stores them differently.
In any case, a .srt file won't help the OP with his TV Guardian problem.
It doesn't matter if I can record the cc data if there is not a way to output it from the pc. Based on earlier posts, a pc cannot ouput the cc data so there is no way to send it to the Guardian for processing.
I have used this for years with dvds and was just hoping to transfer the collection to Media pc and still be able to send cc Data to guardian. I guess it's just not possible.
