ADDRESS BIT
NAME
FUNCTION
8h
0
RSV
Not used.
1
PKTPRTY Arbitrary data packet parity select. When set HIGH, a parity bit is generated
for every user data word (UDW) of an arbitrary data packet. This overwrites
any data input at the PKT[8] pin.
5-2
RSV
Not used.
6
AXST1/2
Audio CH1/2 detection flag. When set HIGH, an audio signal has been
detected.
7
AXST3/4
Audio CH3/4 detection flag. When set HIGH, an audio signal has been
detected.
9h
7-0 PKTLINE[7:0] Arbitrary data packet insertion line. Designates the horizontal line on which
the GS9023A can multiplex arbitrary data packets in the video signal.
Ah
7-0 DELA/B[7:0] Audio control packet delay. Designates the audio control packet delay data
Bh
7-0 DELA/B[15:8] as specified in the SMPTE 272M standard. “DELA” corresponds to audio
channels 1 and 2, while “DELB” corresponds to audio channels 3 and 4.
Ch
7-0 DELA/B[23:16] “DELA/B[25]” is the MSB and “DELA/B[0]” is the LSB.
Dh
1-0 DELA/B[25:24]
2
ACSYNCA/B Audio control packet synchronization data. Designates the sync mode bits
(asx, asy), as defined in SMPTE 272M (Section 14.5), of channels 1/2 or 3/4
of the audio control packet. The bits are selected by “AC34/12” in register
#4h.
3
ACDLY
Audio control packet delay active. Designates the ‘e’ bit of word “DELx0” of
an audio control packet as defined in SMPTE 272 (Section 14.7). When set
HIGH indicates valid audio delay data.
7-4
RSV
Not used.
Eh
0
ANCI_EDH EDH packet ancillary error flag. Error detected here.
1
ANCI_EDA EDH packet ancillary error flag. Error detected already.
2
ANCI_IDH EDH packet ancillary error flag. Internal error detected here.
3
ANCI_IDA EDH packet ancillary error flag. Internal error detected already.
4
ANCI_UES EDH packet ancillary error flag. Unknown error status.
7-5
RSV
Not used.
Fh
0 CRCEDH_A/B EDH packet error flag. “CRCEDH_A” represents Full Field information.
“CRCEDH_B” represents Active Picture information. See “FF/AP_A/B” (bit 7).
1 CRCEDA_A/B EDH packet error flag. “CRCEDA_A” represents Full Field information.
“CRCEDA_B” represents Active Picture information. See “FF/AP_A/B” (bit 7).
2 CRCIDH_A/B EDH packet error flag. “CRCIDH_A” represents Full Field information.
“CRCIDH_B” represents Active Picture information. See “FF/AP_A/B” (bit 7).
3 CRCIDA_A/B EDH packet error flag. “CRCIDA_A” represents Full Field information.
“CRCIDA_B” represents Active Picture information. See “FF/AP_A/B” (bit 7).
4 CRCUES_A/B EDH packet error flag. “CRCUES_A” represents Full Field information.
“CRCUES_B” represents Active Picture information. See “FF/AP_A/B” (bit 7).
5 CRCVLD_A/B EDH packet CRC valid flag. “CRCVLD_A” represents Full Field information.
“CRCVLD_B” represents Active Picture information. See “FF/AP_A/B” (bit 7).
6
RSV
Not used.
7
FF/AP_A/B Full Field/Active Picture select. When set HIGH, the FF (Full Field) information
is displayed in the above mentioned bits. When set LOW, the AP (Active
Picture) information is displayed.
