Video Processing
Figure 9-6 Video processing 2fH/3fH input
The outputs toward the electronics of the set consist of:
•
YUV-422.
•
H-2FH-AD-OUT and V-2FH-AD-OUT.
•
Left and right audio channels (analogue).
•
CLK-2FH.
Notes:
•
In case of 2fH inputs, the signal is (after detection via the
EBILD) routed through the FBX for picture improvement.
The YUV output of the Eagle is then routed to the EBILD
for the displaying part.
•
In case of 3fH inputs, the signal is not routed via the FBX
(because the Eagle cannot handle them), but directly
processed by the EBILD.

Miscellaneous
Comb Filter
The comb filter functionality can be enabled or disabled via the
HIP. This means allowing or disallowing the HIP to use the
comb filter. Both the conventional 2D comb filter (EUR) and the
3D comb filter (USA) have to use this HIP command.
Notes:
•
The command ENABLE_COMBFILTER enables the
function. If the TV standard that enters the TV is one where
a comb filter is applicable (e.g. PAL or NTSC, not SECAM),
the HIP will determine self if the video signal can be
combed and as a consequence, the video processing
output can be CVBS or Y/C. No software interaction is
needed.
Remark: Enabling the comb filter does not necessarily
mean that the signals will be combed.
•
The comb filter must be disabled in case of RGB and for
YPbPr-1fH, to avoid big horizontal shifts of the picture
caused by the comb filter processing.
•
The comb filter is also disabled at very low quality antenna
signals for AP due to vertical instability/scrolling effects.
