M-AUDIO Delta TDIF - Manual (Page 28)

S/PDIF Page
The S/PDIF page of the Delta Control Panel configures the S/PDIF output
format and displays the status of the S/PDIF input. To display this page,
click the "S/PDIF" tab of the Delta Control Panel software.
DIGITAL INPUT: This group box displays the current S/PDIF input status.
The Delta TDIF’s S/PDIF receiver is capable of recognizing a valid input
signal versus an invalid, corrupt or non-present one. When a valid signal is
detected at S/PDIF In, this group box displays "Valid Input Detected."
When an invalid signal is detected or no signal is present, the group box
displays "Invalid or Not Present." Below this message are two ‘grayed-out’
buttons: "Coax(RCA)" and "Optical." These are functions of the Delta DiO
2496, another product in the M Audio Delta line, one with both optical and
coaxial S/PDIF inputs. These controls do not apply to the Delta TDIF.
DIGITAL OUTPUT FORMAT: Within the "Digital Output Format" group,
you choose the digital audio format of the S/PDIF output. The default
setting, "Consumer," is a true S/PDIF format and is recognized by all
consumer devices. The alternate "Professional" setting is an AES/EBU type
data stream, but electrically S/PDIF. This is a work-around that is
recognized by some but not all AES/EBU devices.
For both consumer and professional output formats, the "Advanced"
checkbox will allow you to force a few particular status bits in the outgoing
S/PDIF signal. The advanced option is for expert users only; however, if
you decide to go exploring, change a few bit settings and get lost, you can
always select the "Restore Defaults" button to restore the outgoing status
bits to their factory settings. When "Consumer" and "Advanced" are both
selected, the group "Consumer Format Advanced Settings" will appear.
When "Professional" and "Advanced" are both selected, the group
"Professional Format Advanced Settings" will appear. These groups are
described below:
CONSUMER FORMAT ADVANCED SETTINGS (Copy Mode): Copy
protection, also known as Serial Copy Management System (SCMS), is
written into the S/PDIF subcode, a reserved part of the S/PDIF digital
stream that is independent of the actual audio data being transmitted. It can
be used to inhibit the amount of copies that can be made, or allow for
unlimited copying. Three SCMS modes are available. "Original (Copy
Permitted)" indicates that the source material may be copied by a receiving
device. "1st Generation" indicates that the source material is a first
generation copy. Most devices that are capable of recording will reject
material with this SCMS mode set. The final option is "No SCMS" which
may be used to override the other two modes and allow a recording device
