SD VCR FF/RW SYNC
Subaddress 0x82, Bit 5
In DVD record applications where the encoder is used with a
decoder, the VCR FF/RW sync control bit can be used for non-
standard input video, that is, in fast forward or rewind modes.
In fast forward mode, the sync information at the start of a new
field in the incoming video usually occurs before the correct
number of lines/fields is reached. In rewind mode, this sync
signal usually occurs after the total number of lines/fields is
reached. Conventionally, this means that the output video has
corrupted field signals because one signal is generated by the
incoming video and another is generated when the internal
line/field counters reach the end of a field.
When the VCR FF/RW sync control is enabled (Subaddress 0x82,
Bit 5), the line/field counters are updated according to the
incoming VSYNC signal and when the analog output matches
the incoming VSYNC signal.
This control is available in all slave-timing modes except
Slave Mode 0.
VERTICAL BLANKING INTERVAL
Subaddress 0x31, Bit 4; Subaddress 0x83, Bit 4
The ADV739x is able to accept input data that contains vertical
blanking interval (VBI) data (such as CGMS, WSS, VITS) in
SD, ED, and HD modes.
If VBI is disabled (Subaddress 0x31, Bit 4 for ED/HD;
Subaddress 0x83, Bit 4 for SD), VBI data is not present at the
output and the entire VBI is blanked. These control bits are
valid in all master and slave timing modes.
For the SMPTE 293M (525p) standard, VBI data can be
inserted on Line 13 to Line 42 of each frame, or on Line 6 to
Lind 43 for the ITU-R BT.1358 (625p) standard.
VBI data can be present on Line 10 to Line 20 for NTSC and on
Line 7 to Line 22 for PAL.
In SD Timing Mode 0 (slave option), if VBI is enabled, the
blanking bit in the EAV/SAV code is overwritten. It is possible
to use VBI in this timing mode as well.
If CGMS is enabled and VBI is disabled, the CGMS data is
nevertheless available at the output.
SD SUBCARRIER FREQUENCY REGISTERS
Subaddress 0x8C to Subaddress 0x8F
Four 8-bit registers are used to set up the subcarrier frequency.
The value of these registers is calculated using the following
equation:
