DVD player with Closed Caption via HDMI - is there such a thing ?
Can someone recommend a DVD player capable of decoding Closed Caption on its own and overlaying it on top of video when outputting via HDMI - at least in 1080i (1080p preferred) ?

all DVD-player does it.. DO you know any dvd player which doesn't.. if you press CC on the remote it will show up..
I managed CC over DVI (not HDMI) by using the software DVD player on my Powerbook as that was the only way I could display CC in Hong Kong (i.e. we use PAL). I assume that when HDMI becomes available on laptops, I can use that solution.

I connected a DVR to my TV via HDMI and the CC options were disabled on the TV which makes me think wmcclain is right.
This is different; your computer is integrating the captions into the actual image before sending it to what it believes is the computer display. A stand-alone DVD player has to treat a TV as a TV, and in non-upscaled modes typically passes the CC signal to the TV's CC decoding hardware over extra bandwidth in the signal. There is apparently no extra bandwidth over HDMI, at least for upscaled images. - DR

It seems the situation regarding closed caption and hdmi is probably best described as a clusterf**k. If you had a setup with a composite/S-Video connection and relied on closed caption to be available, you are in a for a big surprise when switching to HDTV.
Here is a link from TEITAC:

"So clearly the authors of the HDMI spec thought the DVD players would decode
captions - they even mistakenly believed that they were required to do so.
Many of the members of the HDMI consortium are also members of CEA ...
So, here we have a situation where the right hand didn't know what the left
hand was doing - and deaf consumers and others who rely on closed captioning
are faced with acceptance of .... a lower quality image (composite video
and last generation DVDs) ..."

I am also looking for a DVD player with CC support (not subtitles) using either component or hdmi connections. SVideo sucks =(
Is there a TV that can display CC over component connection? I have the 65731 right now and it's not displaying it, but am exchanging it for Toshiba 65HM167 (due to other reasons)

This issue has been discussed in the past on one of the Display Devices forums

I see that some of the players here are shown as having CC support: http://www.world-import.com/dvd-hdmi.htm . I know nothing about them otherwise, and would suggest researching to see if CC really is supported for HDMI.

These guys are just resellers. Some of the models they sell support CC over composite and also have HDMI connectivity. None of them show CC over HDMI though.

I contacted CEA - http://www.ce.org/ and they send me back a document - CEA_Closed_Caption_FAQs_April_2007.pdf where they explain their stance on the subject. The doc is on their web site or you can use Google's cache to read a plaint text version of it - http://www.google.com/search?q=cache...April_2007.pdf
CEA apparently thinks the millions of CEA-608 captioned DVDs people already have in their hands will be dumped in the ocean in the near future and everybody will switch to a new medium ( yet to be determined ) and repurchase the same content ( providing it is available ) over again.

Well, that's a terrible waste. The CC info is already in the video signal on current discs; you'd think there would be an automated way of extracting this and converting it to an additional subtitle track at disc authoring time. All current players can handle subtitles. It seems like a small matter of programming to me, but perhaps there is more to it than I suppose.

currently "harassing" SONY over at
http://boardsus.playstation.com/play...ead.id=1929162
hoping that at least PS3 will be able to show captions.

So which upconverting DVD player or which HDDVD player or which BRDVD player can display cc via HDMI? Thanks.
Edit: Sorry link from #11 maybe a good source! I have no expeience though with any from the site.

As reported in the other thread Panasonic EZ47V ( and probably EZ27 ) has the capability of decoding captions when using HDMI. I did not test EZ27 but they both hit the market in May of 2007 so it is safe to assume they share the capability.
I also found two older Toshiba models - SD-3950 and SD-3960 which are able to decode captions and send them over component in 480p mode.
This means that, despite what the DVD player manufacturers want you to believe, closed captions decoding is not quite out of realm of possibility for DVD players.

Thought I'd point out that new DVD *recorders* that have digital (ATSC) tuners have a good chance of decoding captions from a DVD when they play them. For the most part, stand-alone devices with digital tuners are supposed to decode captions. Anytime a device decodes captions and the captioning is turned on within that device, the captions should show up on any display no matter whether HDMI is used. You could even connect the device to a monitor that isn't even a TV (as long as there's a compatible connection) and still see the captioning since it's already been decoded.
Caveat: it's possible that some digital tuners would only decode the CEA-708 caption data, not the line 21 (CEA-608) analog caption data. Closed captioned DVDs have analog, NTSC caption data on them. It would be important to doublecheck whether the recorder would be able to decode the captions from the DVD, even though this would seem like an obvious requirement if there's a built-in caption decoder.

According to the Oppo Early Adopters forum

Oppo is about to release a new blu ray player - BDP-83
The current firmware does not allow for CC decoding from DVDs,
but I am sure if enough people contacted Oppo with their requests it might change.
It is very easy to contact them @ http://www.oppodigital.com/support.htm and they reply almost instantly.

I actually haven't tested it but I presume, like other players, it will give CC over 480i component.
Supporting CC over HDMI: I haven't heard anything about that.
