- I've got some SCMS questions (sorry of this has already been discussed - I
- haven't been reading this thread).
-
- What happens when an SCMS DAT deck is sent a digital source that's
- marked "unrestricted"? Does it create an unrestricted copy or
- does it treat it the same as the analog input - i.e marking it with
- the code that allows one digital copy?
-
- If so, are they any outboard A/D converts that produce a data stream
- with the SCMS code set to unrestricted? I guess that even if these do
- exist, they will cost more than a pro (i.e., non SCMS) DAT deck so it's
- not really an option for someone that wants to make their own
- unrestricted recordings.
-
- I have a pre SCMS DAT deck. What happens when I feed the digital
- output of this deck to an SCMS deck? Does it look like an unrestricted
- source?
-
- Is the coding of the SCMS data such that the receiving deck can tell
- that there is "no SCMS code" in the data stream and treat the input
- differently? Or is was the SCMS code just assigned to bits that
- were always set to a constant value (like 0) in older equipment?
