VIP 2.0 Modes (8 or 16 bits)
VIP 2.0 mode builds on VIP 1.1 with the following changes/
additions:
Video Flags T, F, and V are valid in the EAV and
SAV code, valid values must appear no later then the
SAV of the first scan line of the next active region
(see Figure 6-35).
Task bit differentiates between two video streams.
These streams can be interleaved at a line or field
rate.
New Video Flags - The P Nibble is redefined as
[NON_INT,REPEAT,Reserved,EXT_FLAG].
NON_INT - 1 = non-interlaced source, 0 = inter-
laced source.
REPEAT - 1 = repeat field in 3:2 pull-down,
0 = not a repeat field (tied to 0).
EXT_FLAG - 1 = extra flag byte follows this EAV,
0 = no extra flag byte (this flag is always 0).
