Close captioning over HDMI

I am hearing impaired, so I use Close Captioning a lot.

I have a DVR/DVD recorder that I use for recording OTA programs to watch later.

When the signal from the DVR, is sent to the TV using composite video, I can enable CC on the TV and get the CC content for the program that I am watching.

If the signal is sent to the TV using HDMI, there is no CC.

Is there anyway to make this work using HDMI? I would prefer to use HDMI for a better picture from the DVR.

Thanks,

My answer is not definitive or conclusive, but I would recommend you check al the menus in the DVR. I know that in NTSC (which is the composite or SVH S) the captions are sent during the vertical interval. You used to be able to see them if you had a vertical hold control. Now it takes either a modif ication or a scope with dual time base.

With HDMI there may be a whole different scheme. It is not sso much the hig her resolution that makes me think that, it is possibly other information t hat maty have crowded it out and now it is sent some other way. Simply not being interlaced would change the scheme of things. Or maybe the DVR genera tes it instead of the TV, I do not know but it is possible. If so, remember that if you were to copy it the CC would be one the screen in the dubbed r ecording.

So, look at all the menus, if you do not find anything it may be a limitati on of the system.

Question : Are you simply using the DVR tuner straight off the air ? There is no convertor box ?

Another thing you might consider is seeing how good it looks using SVHS/SVI DEO. It does make a difference. Just not going through the COMB filter help s. It might be good enough because not all OTA material is really high reso lution. when they split one channel into four, it is not quite the highest, like watching a movie at the theater. Between the line doubler and the enh anced video bandwidth it might look good enough.

From what I have been reading HDMI has no "caption Data" which can be turned on/off. It has to be integrated into the HDMI video permanently.

Then it is a deficiency in the DVR. Where else could it be ?

Onl other thing I can say is go in those DVR menus and look or recording op tions and maybe they have wher you shut of CC to enable some "cool" feature you never use.

Also go to the website, they all have a website. Put in the model number WI THOUT the brand name first. Put in the search string "firmware". (without q uotes) Notice if other brands come up, from one of them you might get firmw are.

We could all be wrong here, isn't this format supposed to be the hifi of TV ? Maybe it is like me getting rid of all Windows sounds so I can be onlone and listen to music. i really do not know.

It used to be in the vertical interval in NTSC, which is what composite is. If HDTVs cannot reproduce CC in the highest mode they can otherwise handle , they are in violation of a federal mandate. They deaf community will have their head, and you know what ? Alot of people watch TV with it muted and the CC on even though they can hear. I do hen I watch, my Mother is hard of hearing but the TV has a decent set of speakers on it and she had hearing aids, but we have come to the conclusion that not having these hucksters in our ears is actually better than trying to hear dialog in whispers among a ll kinds of background street sound going through an echo chamber and overl oading the whole story. And I have tried switching it to mono. Sometimes it works, but not all.
