Full Version: missing subtitle mystery

I'm scratching my head on this one. huh.gif I have a dvd player that has a VGA out to hook directly to my lumenlab PJ. If I hook it up to any VGA monitor I can get subtitles but when connected to my lumenlab pJ there are no subtitles.

I have Wagner's complete Ring Cycle on DVD and the whole thing is in German. I like watching it with English sub-titles so I know what is going on. I also like to watch Crouching Tiger, Hidden Dragon in Mandarin Chinese with subtitles on. My daughter takes French and I would like her to be able to watch movies in French with english subs or the other way around.

I have messed with all the settings in the DVD player that I can think of. Besides, the settings that work on any other monitor just don't work on mine. My projector uses a benq 567s v2. Isn't the monitor just a passive device or is there some signal that it has to decode to display the subs?

Hi Kjudki,

Not 100% sure on this one. Sounds very odd. However I do vaguely recollect something from my DVD authoring days about "closed captions" being a function of the display device. Embedded in the video signal. If your disks use this method for subtitles perhaps the monitor doesn't like it. Generally speaking I thought subtitles were rendered by the player but possibly not always.

I could also be talking complete cr#p.. I'd do a search on the web for "closed captions" and see if it turns up anything.

Cheers,
Arkay.

My lumenlab pj will do captions from my laptop but then I can't hook audio up to the surround system. My laptop sends 1024 x 768 to the PJ. I don't think that the DVD player sends as high of a signal. Maybe captions need more resolution to render.

Bizarre.

I also thought the player rendered the the captions - Hmm - Did you say youc an hook the dvd player up to the regualr tv and get captions?

Dang Man you got me on this one I would assume that if you are able to hook it up to a diff. VGA moinitor (CRT) and it works then you would get the same with the LCD panel?

I am very curious about this now. take some pics of it working and not working on the diff. monitors.

But there has to be a solution there alwayz is biggrin.gif

Where theres a will theres a way.

Strange kjudki, I will have to do some testing and see what I can find out.

Same LCD BenQ 567s Version 2

I have an idea. My wife complained once that she had 2 sets of subtitles on the screen at the same time. It turned out that the DVD player was outputting subtitles, and the TV was doing it too. I turned OFF the subtitles/captions option in the DVD player, which then doesn't send them on to the TV to be displayed. This is SEPARATE from the DVD player actually decoding the subtitles/captions and adding them to the picture that it sends on. I only get subtitles now if i CHOOSE the captions from the DVD's menu system. Some dvd's don't have an option for subtitles, but the video has them encoded in the stream.. For those dvd's I have to turn the subtitle option back on so that the TV can display the stream for me.


Just thinking... try looking in the dvd player's menu system for an option to turn on captions. (separate from the one that is in a movie's menu system.)

While we're on the subtitles issue. Let's say you watch a 2.35:1 movie, and you cover the screen's top and bottom "gray bars", with some black material, do you know an easy way to elevate the subtitles to be displayed only above the lower black bar ?. Is this a common feautre with retail DVD players ?.

I have one solution for this with a pc, but it is cumbersome.

I assure you a computer monitor has no idea whatsoever how to decode closed captioning. It is in the input device, the player.

The only thing that comes to mind, solution wise, is to shrink your projected image (using the monitor's controls) to the minimum size. The player, when connected to the projector, may have some of the image information off screen (the subs).

I imagine the player is outputting 480p, no where near the 1024.768 of your computer, and very very very likely a different refresh rate as well. I notice on all my analog monitors, that different resolutions (or refresh rates) always shift my image up/down or to the side, and the size often is affected as well. DOS mode sometimes is nearly half off the screen to the left, for example.

So to reiterate, use the pj's screen controls to shrink the image as much as possible, as the different resolution and refresh rate of the player may have shifted the sub-titles off the screen. If they still don't show....take two aspirin and call me in the morning.

Any luck?

Tony,
When I realized that the Yamakawa DVD player's resolution was so low (640 x 480 at 50Hz), I switched to a computer. I'll probaly use the DV player on a regular TV or give it to a friend that doesn't have one.

Thanks for asking.
kjudki
BTW-- I couldn't shrink the image enough for the captions to show up --- if that was the problem.

because i am hearing impaired, i have viewsonic N5 that comes with built in CC(closed captions) chip. if you have tv turner with built in CC chip, u can hook up the wires from DVD player to a PJ thur that box. let see if CC comes on screen. personally i dont have the PJ myself. i am working on process before i ll start building the PJ, anyway.

Viewsonic's N5 and N6 come with the CC chips, not sure about N4.

AverMedia's TvBox 9 has CC chip.

i do not know other tv tuner box that has built in CC chip.

good luck.

If you use an HTPC instead of an external box, then the ATI series video cards support CC.

Sounds like a player issue. They're probably being displayed off screen. Have you tried hooking the projector up to your PC and running DVD software?
kjudki
Golly! Is this thread still getting posts? I appreciate your help and concern guys but that problem was 10 months ago! That was 37,693 problems ago. I don't use the (overly complicated) Yamikawa DVD player with my projector anymore. Instead the lumenlab PJ is hooked directly to a computer with a DVD player.

yea i know it s old post but it is important to educate some of us like hearing impaired enthusiastic PJ builder or builder who may have hearing impaired relatives. or friends.

i am pretty excited that video card that now has built in CC because i want to have it for my PC. thanks This is Me cuz i had been waiting for video card with CC for some times.

Huh. I thought it was a new thread that just started a couple days ago. I never check dates on posts.
