1 - Received channel status block is in the professional format.

COPY - SCMS copyright indicator

0 - Copyright asserted.

1 - Copyright not asserted. If the category code is set to General in the incoming AES3 stream, copyright

will always be indicated by COPY, even when the stream indicates no copyright.

ORIG - SCMS generation indicator, decoded from the category code and the L bit.

0 - Received data is 1st generation or higher.

1 - Received data is original.

Note:

COPY and ORIG will both be set to 1 if incoming data is flagged as professional or if the receiver

is not in use.

EMPH – Indicates if the input channel status data indicates that the incoming audio data has been pre-em-

phasized.

0 – 50

µs/15 µs pre-emphasis indicated.

1 – 50

µs/15 µs pre-emphasis not indicated.

11.18 Format Detect Status (12h)

Note:

PCM, DTS_LD, DTS_CD and IEC61937 are mutually exclusive. A ‘1’ indicated the condition

was detected.

PCM – Un-compressed PCM data was detected.

IEC61937 – IEC61937 data was detected.

DTS_LD – DTS_LD data was detected.

DTS_CD – DTS_CD data was detected.

HD_CD – HD_CD data was detected.

DGTL_SIL – Digital Silence was detected: at least 2047 consecutive constant samples of the same 24-bit

audio data on both channels.

11.19 Receiver Error (13h)

This register contains the AES3 receiver status bits. Unmasked bits will go high on occurrence of the error,

and will stay high until the register is read. Reading the register resets all bits to 0, unless the error source

is still true. Bits that are masked off in the receiver error mask register will always be 0 in this register.

QCRC - Q-subcode data CRC error indicator. Updated on Q-subcode block boundaries

0 - No error.

1 - Error.
