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 ADV7170/ADV7171 are 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 synchroni-
zation pattern. A synchronization pattern is sent immediately
before and after each line during active picture and retrace.
Mode 0 is shown in Figure 20. The HSYNC, FIELD/VSYNC,
and BLANK (if not used) pins should be tied high during this
mode.
