VDP Manual Configuration
MAN_LINE_PGM, Enable Manual Line Programming of
VBI Standards, Address 0x64 [7], User Sub Map
The user can configure the VDP to decode different standards on
a line-to-line basis through manual line programming. For this,
the user must set the MAN_LINE_PGM bit and write to the
VBI_DATA_Px_Ny line programming bits (see Register 0x64
to Register 0x77 of the user sub map).
0 (default)—The VDP decodes default standards on lines as
shown in Table 66.
1—The VBI standards to be decoded are manually
programmed.
VBI_DATA_Px_Ny [3:0], VBI Standard to be Decoded on
Line x for PAL, Line y for NTSC, Addresses 0x64 to 0x77,
User Sub Map
These bits are related 4-bit clusters in Register 0x64 to Register 0x77
of the user sub map. The 4-bit line-programming registers, named
VBI_DATA_Px_Ny, identify the VBI data standard that would be
decoded on Line x in PAL mode or on Line y in NTSC mode. The

different types of VBI standards decoded by VBI_DATA_Px_Ny
are shown in Table 67. Note that the interpretation of its value
depends on whether the ADV7184 is in PAL or NTSC mode.
Notes
•
•
Full field detection (lines other than VBI lines) of
any standard can also be enabled by writing into the
VBI_DATA_P24_N22 [3:0] and VBI_DATA_P337_N285 [3:0]
bits. Therefore, if VBI_DATA_P24_N22 [3:0] is programmed
with any teletext standard, then teletext is decoded from
the entire odd field. The corresponding bits for the even
field are VBI_DATA_P337_N285 [3:0].
In teletext system identification, VDP assumes that if teletext
is present in a video channel, all the teletext lines comply with
a single standard system. Therefore, the line programming
using VBI_DATA_Px_Ny registers identifies whether the
data in line is teletext; the actual standard is identified
by the VDP_TTXT_TYPE_MAN bit. To program the
VDP_TTXT_TYPE_MAN bit, the VDP_TTXT_TYPE_
MAN_ENABLE bit must be set to 1.
