Figure 19. RTC Timing and Connections
Vertical Blanking Data Insertion
It is possible to allow encoding of incoming YCbCr data on
those lines of VBI that do not bear line sync or pre-/post-
equalization pulses (see Figure 21 to Figure 32). This mode of
operation is called partial blanking and is selected by setting
MR32 to 1. It allows the insertion of any VBI data (opened VBI)
into the encoded output waveform. This data is present in the
digitized incoming YCbCr data stream, for example. WSS data,
CGMS, VPS, and so on. Alternatively, the entire VBI may be
blanked (no VBI data inserted) on these lines by setting MR32
to 0.
Mode 0 (CCIR-656): Slave Option
(Timing Register 0 TR0 = X X X X X 0 0 0)
The ADV7174/ADV7179 is controlled by the SAV (start active
video) and EAV (end active video) time codes in the pixel data.
All timing information is transmitted using a 4-byte synchro-
nization pattern. A synchronization pattern is sent immediately
before and after each line during active picture and retrace.
Mode 0 is illustrated in Figure 20. The HSYNC, FIELD/VSYNC,
and BLANK (if not used) pins should be tied high during this
mode.
Mode 0 (CCIR-656): Master Option
(Timing Register 0 TR0 = X X X X X 0 0 1)
The ADV7174/ADV7179 generates H, V, and F signals required
for the SAV and EAV time codes in the CCIR-656 standard. The
H bit is output on the HSYNC pin, the V bit is output on the
BLANK pin, and the F bit is output on the FIELD/VSYNC pin.
Mode 0 is illustrated in Figure 21 (NTSC) and Figure 22 (PAL).
The H, V, and F transitions relative to the video waveform are
illustrated in Figure 23.
