Creating a Closed Caption Sub-Master Tape
Once all the steno work is done, do you need a special deck to record from the encoder to line 21? I assumed any deck should be able to do it but a colleage tells me only certain decks will do it. I would think you pass the master through the encoder along with t/c and record the sub-master with line 21 filled in from the encoder.
Can anyone explain the proceedure? Will a uvw-1800; dsr 80; dsr-85; or AJ-d750; AJ-d650 be capable of recording this sub-master?

Your colleague is mistaken.
However, you should commit to extensive testing. Better than that, hire it done by a captioning service. You are going to find out there are lots of weird little things that can go wrong when attempting to run closed captioning.

I’m looking into this myself and there seems to be two options: the typical one is software and hardware (encoder), and the the other which is maccaption that accomplishes with a software solution. One thing to keep in mind is that you need a digital work flow.

Thanks for your help, I’m with clients all day so will check these out later. Basically someone needed to borrow a deck to record from their encoder as “their decks wouldn’t do it”. I questioned the logic behind this as from my understanding from about lines 18 -28 ntsc has reserved for these types of data, line 21 being CC. I’ve never needed to work with them but have seen on the waveform and been aware they are there and I ASSUMED any deck could record or play as they are part of the ntsc signal. What would my aj-d750 have that their 650 or 640 doesn’t have or their uvw-1800; D-9; DSR-80? All these I would think should work but then I don’t know everything either.

It sounds like there could be several issues. A few things to consider – 1) Is the caption file the correct format? 2) Which captioning field is the encoder set to place the caption data? 3) Did they run the video back through a TV set with a decoder to see the captions?
In the future, you could use our company to create a caption file that goes right into your editing system. There is no need for an encoder and there is no generation loss. Feel free to give me a call and I’ll help you understand the different options. We have a full studio with several encoders and multiple format decks so we’ve seen most issues and had to resolve them.
