Input De-multiplexer
Refer to the Input De-multiplexer discussion in the interpolation mode section.
Horizontal Blanking
Refer to the Horizontal Blanking discussion in the interpolation mode section.
Input Offset Adjustment
Refer to the Input Offset Adjustment discussion in the interpolation mode section.
3X3 Color Space Converter and KEY Scaler
Refer to the 3X3 Color Space Converter and KEY scaler discussion in the interpolation mode section.
MATRIX OUTPUT RESOLUTION
Full precision is maintained throughout the 3X3 matrix multiplication. To ensure that maximum precision is maintained by the
GF9105A, rounding of the Y/G, CB/B and CR/R channels depends on the state of the RND8/10 and BYPASS_F control bits
(See HOST Programming Section).
