[Athen] Multimedia Projector and Captioning

Windows Media Player supports line 21 closed captions as can most
software players. It seems most DVD players (standalone) support line
21. The only problem is very few DVDs actually have line 21 data. HD
DVD formats don't support it. My feeling is unless you are going to be
showing VHS or TV signals through the project its not worth the extra
money or weight to support closed captions. That's my feelings

Before deciding what to buy, you need to understand a bit about closed
captions and consider how you will use the projector.


If you are playing VHS tapes that have closed captions and projecting
them through this projector, then you will need the decoder. I suspect,
however, that is unlikely to be the case. Unlike an overhead projector
that has everything wired through it, the presentation projectors for
use with computers are rarely used to show VHS tapes. Generally when
showing VHS tapes, a TV and a VHS player are brought in. The TV has the
decoder built-in, so you would not need a projector with a decoder.


If you have a DVD with actual closed captions (as opposed to subtitles
for the deaf, which are turned on through the DVD's menu) and you wish
to show it on your computer, then you will need a decoder in the
projection unit. You would need to weigh the likelihood of showing a DVD
on a computer, as opposed to bringing in a separate DVD player and TV.


Video captions on the Web are turned on and off through the media player
or with a special CC button. No decoder is required.

To summarize, if weight and portability are issues, and DVD/VHS players
connected to a TV will be available, then you will not need the decoder.
If, however, you need one unit to "do it all," then get the Epson.

Hope this helps!

We are trying to buy a Multimedia Projector for doing presentations for
our Disability Resource Center here at UIC. I found out that Epson has
a projector that has built in closed captioning capability. It is
called the PowerLite 83c. I am trying to wrap my brain around how this
works on a practical level. Has anyone used one? It is heavier than
the one I was looking at from Dell but if it has a tremendous advantage
for the hearing impaired, I would look into us buying it.

Thank you for any feedback,
