What, more details than the subject? Ok...

What options do those of use keeping 35mm's, particularly in side-by-side installations have?

And what's the cheapest digitial captioning system?

Thanks!

For film, Datasat has been the company that does it and it was Rear Window for "closed captions" (as well as for Open Captions).

In Digital, USL has taken the lead for closed captions. http://www.uslinc.com/products-sound-CCS.html

The text info is on the Ethernet of the auditorium. Open caption can be done by the projector itself and there are open caption versions of the movies.

For digital we have the DoReMi Captive View at one location - they use a USB transmitter plugged into each server . . . . seems to work well so far.

I have not done a full cost comparison between them and USL yet.

If I am not mistaken Rear Window can be made to work with both 35mm and digital.

for 35mm we only ever used Datasat for open captions, it has been a while and I forget pricing.

Some digital cinema servers support Rear Window directly out of an RS232 port on the back. For others, the USL CCE-100 can be used to convert the SMPTE captioning protocol to RS232 for Rear Window.

As pointed out above, USL provides the IRC-28C IR panel that transmits HI/VI-N audio plus four languages of closed captions. Various receivers are available for the HI/VI-N audio and the closed captions. The HI/VI-N inputs are balanced analog audio. The captioning is received using the SMPTE Auxiliary Content Synchronization Protocol over Ethernet. An introduction to SMPTE closed captioning is in the manual for the UPC-28C (or IRC-28C) at http://www.uslinc.com:8880/ftp/IRC-28/Manual/IRC-28C.pdf .

Let me know of any questions or problems with closed captioning. Since I designed the USL system, any problems are my fault, and I'd like to get them resolved.

Thanks!
