“Raw” VBI Data Capture
“Raw” data capture of VBI data during blanked scan lines
may be optionally implemented. In this instance, the active
line time of blanked scan lines are sampled at the CLK2 rate,
and output onto the pixel outputs. This permits software
decoding of the VBI data to be done.
The line mask registers specify on which scan lines to gen-
erate “raw” VBI data. If the RAW VBI All bit is enabled, all the
video lines are treated as raw VBI data, excluding the equal-
ization and serration lines.
The start and end timing of capturing “raw” VBI data on a
scan line is determined by the Start and End Raw VBI Reg-
isters. This allows the proper capture of “raw” VBI data
regardless of the BLANK# output timing for active video.
The blanking level is subtracted from the “raw” VBI data
samples, and the result is output onto the pixel outputs.
Note both “sliced” and “raw” VBI data may be available on
the same line.
During NTSC operation, the first possible line of VBI data is
lines 10 and 272, and the last possible lines are the last
blanked scan lines. Lines 1-9 and 264-271 are always
blanked.
During PAL (B, D, G, H, I, N, N
C
) operation, the first possible
line of VBI data are lines 6 and 318, and the last possible
lines are the last blanked scan lines. Lines 623-5 and 311-
317 are always blanked.
During PAL (M) operation, the first possible line of VBI data
is lines 7 and 269, and the last possible lines are the last
blanked scan lines. Lines 523-6 and 261-268 are always
blanked.
REAL TIME CONTROL INTERFACE
The Real Time Control Interface (RTCI) outputs timing infor-
mation for a NTSC/PAL encoder as BT.656 ancillary data.
This allows the encoder to generate “clean” output video.
NOTES:
34. The MSB is bit number: 271 for system C, 279 for system B 525-line and 343 for system B 625-line.
35. The clock run-in is 16 bits wide for both systems and is not included in the BT.656 ancillary data stream.
36. The bit rate is 5.727272 Mbits/second for system B and C on 525/60 systems and 6.9375 and 5.734375 Mbits/second respectively for
625/50 systems.

NOTES:
37. ep = even parity for P8-P13.
38. CRC = Sum of P8-P14 of Data ID through last user data word. Preset to all zeros, carry is ignored.
39. For 525-line system B, bits 280-343 are “0”.
40. For system C, bits 272-343 are “0”.
