Selecting the main ID6 display (mode No.5)
(1) SCMS
The Serial Copy Management System (SCMS) is designed to control digital-to-digital DAT copying that a
consumer can perform on various digital audio material, including Compact Discs, pre-recorded DAT tapes,
and other material via IEC 958 "consumer use" digital audio interfaces (also commonly referred to as "S/P DIF").
SCMS does not affect the ability to make copies using a DAT recorder's analog inputs and outputs.
Only one serial (or generational) digital-to-digital copy can be made from a copyright protected source, such as
a commercial CD or pre-recorded DAT. Serial Copy Management System labels are generated onto tape each
time an SCMS-equipped consumer DAT machine records an audio signal to tape, no matter whether the source
is from the analog or digital inputs.
(2) Setting the main ID6
Technically, the SCMS labels for DAT are encoded into the sub code sections of the main digital data area,
specifically "main ID6". The SV-3800 allows the user to preset the SCMS status bits of main ID6 onto the DAT
recording. For legal reasons, the ID6 bits are only modified if the source input is the AES/EBU Digital I/O or
analog input; during digital copying via the IEC "consumer use" input, the SV-3800 simply copies across the
current status of SCMS codes from the source tape.

Display example: When "11P00" is displayed
The first two digits denote the value of main ID6 which is
"user-selectable bits" and to be recorded onto the tape during recording.
In this case, these digits are "11."
The last two digits denote the value of main ID6 which has been recorded
onto the tape being played back. In this case, these digits are "00."
To change the setting:
Press the SKIP button (forward). The display changes in the sequence of 1) through 3) above, thus changing the
value of main ID6 which is to be recorded onto the tape during recording. The setting established after
initialization is "00."
