The STATUS area provides information on various signal status of incom-
ing S/P-DIF optical or coaxial digial audio signals. Incoming AES3 or AES3id
signals will be not evaluated by this function because of the lack of the
corresponding status bits within these data streams.

»ORIG«
This status LED indicates when the incoming digital audio signal of the
active S/PDIF input is SCMS-encoded as original source.

»1st«
This status LED indicates when the incoming digital audio signal of the
active S/PDIF input is SCMS-encoded as 1st copy.

»NONE-PCM«
This status LED indicates when the incoming digital audio signal of the active
S/PDIF input is a none-standard PCM data stream, e.g. AC-3, MPEG, etc.

»DTS-CD«
This status LED indicates when the incoming digital audio signal of the
active S/PDIF input is a DTS-CD bitstream (DTS = Digital Theatre System).

SCMS Functions

SCMS (Serial Copy Management System) settings, also know as »copy
protection bits«, affect the S/P-DIF optical and coaxial output signals
only. The AES3 and AES3id output signals are not affected because the
corresponding AES specifications do not define any SCMS encoding. Due to
this, the AES3 and AES3id output signals are free of SCMS information.

SCMS functions can be set independently of the SCMS status of an incoming
S/P-DIF signal. They are not available using the split mode.

»ORIG«
This function called »Original« sets the outgoing SCMS data-bits to indicate
that the signal source is the original master and not a copy. Therefore,
devices which are capable of evaluating SCMS data-bits will accept those
digital audio signals at their S/P-DIF inputs for recording.

»1st«
This function called »1st Generation« sets the outgoing SCMS data-bits
to indicate that the signal source is a copy. Therefore, devices capable of
evaluating SCMS data-bits will not accept those digital audio signals at
their S/PDIF inputs for recording. Due to this, valuable recordings, sounds or
commercial material will be protected against illegal copying.

»PASS«
This function transmits all SCMS information received at the active S/P-DIF
input/s to all S/P-DIF outputs without any modification.
