Well, you make a distinction that I hadn't thought of. When I thought "3D Captions", I was thinking about captions made from essentially flat letters, except they would appear at different depths, perhaps representing the position of the speaker within the depth of field of a scene. Your...

that is correct. other sources include various satellite receivers and cable receivers, as well as OTA receivers. It seems to be working pretty well in about 95% of the installations so far. The few glitches seems to be from (a) less-than-perfect HDMI interface issues (HDMI isn't quite a...

No, my product is indeed a consumer product. I'll be introducing a model soon for the deaf and hard of hearing community which should fully support closed captions (the current product only supports a limited subset for Pop-On mode only). If you wanted to test your 65 in Plasma for the CC...

Peter: good point. way back in the beginning of this thread, I introduced that I am making an external, stand-alone HDMI closed caption decoder. Since of course CC signal is not on HDMI, I am taking advantage of the fact that almost all HDMI video sources these days also have a simultaneous...

I think we need a different terminology when talking about displaying any type of captions, closed, decoded, or subtitles on the HDMI interface. There simply IS NO method to transmit closed captions on HDMI, period. If you see captions, or any kind of text, it is being superimposed on the...

My limited testing with BluRay players (I have a Sony and a Samsung model) is that they WILL transmit Line 21 CC out the analog port. I haven't investigated whether they will decode and transmit them as open captions on the HDMI port or not - probably not, as this is kind of an unusual function...

Peter, thanks for the tuner information. I do wonder if the Media Center would decode and record CC signal from analog inputs. I'll have to research that some, it might be quite useful to me in my lab and for factory testing. BTW, my interest in Panasonic DVD recorders is that they are one...

Peter: I have heard similar reports as yours. But just to clarify, technically speaking, none of the situations you have described are actually carrying "closed captions" over HDMI. Rather, your software/hardware has decoded the closed caption signal from the source program and displayed...

john57: I have heard positive reports about Panasonic DVD recorders as well, being one of the few brands that will correctly capture and record the CC data on your DVD. But I'm talking in the analog video world, or perhaps using now-obsolete analog OTA broadcasts. I don't know if newer...

Very interesting subject. I am an engineer and design set top boxes for closed captions. I'm currently working on one which supports HDMI. I noticed that the basic hardware I'm using supports 3D, and that got me wondering whether one could make the captions them selves 3D. I don't think...

Anij: Good points. Keep in mind, I'm not generating captions, just displaying them. Since things like underlining, flashing and italics and colors are in the captioning standard, I'm compelled to consider them in my design. It would be good to hear how prevalent these features are used in...

Ok, as my design progresses, I have some more questions regarding text attributes. (Please remember I'm talking about the old style, Line 21 captions, and not the new HDTV captioning style). The law governing the design of caption decoders specifies that text can be displayed "with any or...

MayGuy - well, if the X-Box doesn't output CC, even though the disc has CC, then there is no way that the box I'm designing could work with the X-Box. That said, I haven't specifically tested an X-Box to know for sure.

Thanks, GadgetQueen. Good points, especially regarding interfacing to additional equipment.

I'm not quite clear about your question - this box will go between your HDMI video source (cable receiver, satellite receiver, DVD player, etc) and your HDTV. Initially I envision the unit only doing HDMI video signals, although HD component video might be added in the future. Does this answer...

Hask12 - sorry if I was too technical. To answer your question, this new box will only display existing captioned programs. The problem this addresses is cable and satellite boxes which either (a) don't display captioning, or (b) make it very difficult to display and control captioning...

The traditional, line-21 style captions are formally documented and defined in the EIA-608 standard (although as I recall, it wasn't 100% complete - to truly define a CC decoder function I needed a couple of additional documents, the old Telecaption-II report and perhaps one of the FCC...

Hello. I am new to the group. I am a design engineer, having worked on several video set-top boxes using Closed Captioning over the past 10 years. I have a new project this summer to make an HDMI set top box which will also display closed captioning - therefore one will be able to watch high...
