Adaptive comb mode.
Disable luma comb.
Fixed luma comb (top lines of line memory).
Fixed luma comb (all lines of line memory).
Fixed luma comb (bottom lines of line memory).
Configuration
Adaptive 5 lines (3 taps) luma comb.
Use low-pass/notch filter; see the Y-Shaping Filter section.
Fixed 3 lines (2 taps) luma comb.
Fixed 5 lines (3 taps) luma comb.
Fixed 3 lines (2 taps) luma comb.
Insertion of AV codes into the data stream.
Data blanking during the vertical blank interval (VBI).
The range of data values permitted in the output data
stream.
The relative delay of luma vs. chroma signals.
Note that some of the decoded VBI data is being inserted
during the horizontal blanking interval. See the Gemstar Data
Recovery section for more information.
BT656-4 ITU Standard BT-R.656-4 Enable, Address 0x04 [7]
The ITU has changed the position for toggling the V bit within
the SAV EAV codes for NTSC between revisions 3 and 4. The
BT656-4 standard bit allows the user to select an output mode
that is compliant with either the previous or the new standard.
For more information, review the standard at http://www.itu.int.
Note that the standard change affects NTSC only and has no
bearing on PAL.
0 (default)—The BT656-3 specification is used. The V bit goes
low at EAV of Lines 10 and 273.
1—The BT656-4 specification is used. The V bit goes low at
EAV of Lines 20 and 283.
SD_DUP_AV Duplicate AV Codes, Address 0x03 [0]
Depending on the output interface width, it may be necessary to
duplicate the AV codes from the luma path into the chroma path.
In an 8-/10-bit-wide output interface (Cb/Y/Cr/Y interleaved
data), the AV codes are defined as FF/00/00/AV, with AV being
the transmitted word that contains information about H/V/F.
In this output interface mode, the following assignment takes
place: Cb = FF, Y = 00, Cr = 00, and Y = AV.
In a 16-/20-bit output interface where Y and Cr/Cb are delivered
via separate data buses, the AV code is over the whole 16/20
bits. The SD_DUP_AV bit allows the user to replicate the AV
codes on both buses, so the full AV sequence can be found on
the Y bus and on the Cr/Cb bus. See Figure 25.
0 (default)—The AV codes are in single fashion (to suit 8/10 bit
interleaved data output).
1—The AV codes are duplicated (for 16-/20-bit interfaces).
VBI_EN Vertical Blanking Interval Data Enable,
Address 0x03 [7]
The VBI enable bit allows data such as intercast and closed
caption data to be passed through the luma channel of the
decoder with a minimal amount of filtering. All data for Line 1
to Line 21 is passed through and available at the output port.
The ADV7188 does not blank the luma data, and automatically
switches all filters along the luma data path into their widest
bandwidth. For active video, the filter settings for YSH and YPK
are restored.
