We are using the ADV7343, also we inputs H_SYNC/V_SYNC(P_HSYNC/P_VSYNC) from external.
And, we need Black Burst(tri-level sync of HD, bi-level sync of SD) output signal.
Do we need to aply specific data for pixel inputs during "Blanking terms" ?
For example, 0x3F, 0x00, etc.
(We do not use CGMS, WSS, VITS.)
Our board design is, input pixel signals tied to Low or High, and their is not controlable. (Y=0x80, S=0x80, C=0x80, each signals tied VDD/GND.)
