AV CODE INSERTION AND CONTROLS
This section describes the I2C-based controls that affect the
following:
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
Some of the decoded VBI data is inserted during the horizontal
blanking interval. See the Gemstar Data Recovery section for
more information.
BT.656-4, ITU-R BT.656-4 Enable, Address 0x04[7]
Between Revision 3 and Revision 4 of the ITU-R BT.656 standards,
the ITU has changed the toggling position for the V bit within
the SAV EAV codes for NTSC. The ITU-R BT.656-4 standard
bit allows the user to select an output mode that is compliant
with either the previous or new standard. For further information,
visit the International Telecommunication Union website.
Note that the standard change only affects NTSC and has no
bearing on PAL.
When ITU-R BT.656-4 is 0 (default), the ITU-R BT.656-3
specification is used. The V bit goes low at EAV of Line 10
and Line 273.
When ITU-R BT.656-4 is 1, the ITU-R BT.656-4 specification is
used. The V bit goes low at EAV of Line 20 and Line 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-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-bit output interface (64-lead LQFP only), where Y and
Cr/Cb are delivered via separate data buses, the AV code is
spread over the whole 16 bits. The SD_DUP_AV bit allows the
user to replicate the AV codes on both buses; therefore, the full
AV sequence can be found on the Y bus as well as on the Cr/Cb
bus (see Figure 36).
When SD_DUP_AV is 0 (default), the AV codes are in single
fashion (to suit 8-bit interleaved data output).
When SD_DUP_AV is 1, the AV codes are duplicated (for
16-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 ADV7180
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.
section for information on the chroma path.
When VBI_EN is 0 (default), all video lines are filtered/scaled.
When VBI_EN is 1, only the active video region is filtered/scaled.
