"Close Caption" on Sony DVD Player

post #1 of 5
Thread Starter 
While I own and use a Panasonic BD30 player (mostly for playback SD DVDs because I'm a old-film collector) and it does a great job of upscaling older DVDs, including those I've dubbed on my Panny EH55, I may soon have access to a Sony DVD SD DVD player and a "projector" to which I can attach the Sony player to output "large" images on various handy walls. I've discovered somewhat belatedly that my EH55 has recorded and I've subsequently dudded to DVD-Rs films with Close Captioning. Although it took a long time to discover this, I found it quite accidentally when I went back to check my Panny plasma display manual and found that if I could selected "CC on" in "set up" and used the EH55 as the plaing device, the CC "subtitles" magically appeared. I did discover that it doens't work with HDMI connections, hence playing a CC-enhanced DVD on my BD30 doesn't work and my S-video connected EH55 to Pnny display does as long as "CC on" has be set up.

Finally, my question: Do any, few or many SD DVD players such as a Sony "read" CC coding (perhaps through use of the remote) so that it can be projected through a (probably code-neutral) projector onto a wall? I have some friends and relatives with various levels of hearing loss who could benefit from the CC option.

PS from OP:

I've now found that some commercial DVDs have a "hidden" CC option, i.e., it does not appear anywhere in the playing menu, but actually exists and could appear visually if "CC on" could be turned on in the player itself, something that's not possible with the project alone. For example, I viewed a recent commercial DVD which had Spanish and French subtitles (but not English, which I needed) on its menu. I could never have found the CC option if I'd I'd not set it on my Panny display and played it through the S-video out on my EH55 DVDR.

This comes up from time to time; if you search the whole forum for "closed captions" you may find old discussions.

Very few DVD players decode CC for HDMI output. For background on why see:

http://en.wikipedia.org/wiki/Closed_captions#DVDs

...and this from an HDMI article (http://en.wikipedia.org/wiki/High-De...ia_Interface):

Quote:


The HDMI standard was not designed to pass closed caption data (for example, subtitles) to the television for decoding.[53] As such, any closed caption stream must be decoded and included as an image in the video stream(s) prior to transmission over an HDMI cable to be viewed on the DTV. This limits the caption style (even for digital captions) to only that decoded at the source prior to HDMI transmission. This also prevents closed captions when transmission over HDMI is required for upconversion. For example, a DVD player that sends an upscaled 720p/1080i format via HDMI to an HDTV has no way to pass Closed Captioning data so that the HDTV can decode it, as there is no line 21 VBI in that format.

If the TV has a CC decoder, then I believe any DVD player using composite, s-video, or component (using 480i output resolution) output would work.

It's a shame the industry dropped the ball in the transition to HDMI; all the CC effort lost.

Recently I discovered some media file tools will extract CC and convert it to text-based SRT subtitles for inclusion in media containers like MKV. HandBrake will do it, for example. But that's a lot of work if you are not already doing it.

Thanks for the clarifications re HDMI. What I want to do is output via composite, component or S-video--but not HDMI--a viewable signal that can be projected on a non-active surface, i.e., not to a television display. I can do that already on my own Panny plasma display because the display itself has a "CC on" options.

I did read a thread mostly discussing the use or non-use of CC-coded programs with HDMI inputs and outputs but that does not address my purposes.

Could it be that there are no SD players that can output through a "dumb" projecting device, but that CC can only be decoded and displayed through an electronic display itself such as most modern TV displays such as my Panny?

I believe that is the case: the display itself must have a CC decoder. In that case the player isn't doing anything special, just sending the video over the analog output as it normally would. The display detects the CC, decodes and displays them.

I recall reports that some DVD player(s) decoded CC and sent them out over HDMI (or other output?) but don't recall the model(s). For some reason I thought this might be more likely on DVD recorders, but I never investigated.

You might google around the disabilities sites to see if you can find specific recommendations. Or here at AVSForum, although I'm not sure when or where the discussions occurred.

You might also look at PC software like VLC, which is free. It will display CC. Maybe a laptop would serve instead, either on it's own screen or via video out to a display device.

Sorry I can't be more help. I like subtitles too and this is a sore point.
