2.2.2.1 FAV & BAV & B_SVHS & F_SVHS
B_SVHS and F_SVHS inputs can not be supported at the same time.
FAV & B_SVHS_Y & F_SVHS_Y inputs use same CVBS input. (cvbs2/74)
B_SVHS_ C & F_SVHS_C input is C2/C3(70).
FAV audio input is AUDIOin_5 L,R (94,95) and shared with F_SVHS.
BAV video input is CVBS1 (81) and can not be supported with SCART3 at the same time.
BAV audio input is AUDIOin_4 L,R (80,79) and shared with SCART3.
2.2.2.2 SCART1
SCART1 video input is (CVBS3/71) . SCART1 video input is also applied to Video Switch
IC(TEA6415C) for PIP application.
SCART1 video out will use (IFVO/86) front_end video output, that output is also used as SCART3
video output via a buffer circuit.
SCART1 RGB/fblk inputs are R(51), G(50), B(49), FBLK(52) .
SCART1 AUDIO input is AUDIOin_3 L,R ( 73,72) .
SCART1 AUDIO output is AUDIOout_SR,SL (93,92). Same output also used as SCART3 Audio output.
2.2.2.3 SCART2
SCART2 video input is CVBS4 (78) . SCART2 video input is also applied to Video Switch IC(TEA6415C)
for PIP application.
SCART2 supports SVHS input. SVHS / C input is C4 (77) , Y input is use same video input.
SCART2 video output is CVBSO/PIP (65). That video output is selectable, all inputs can be selected to
be output from SCART2.
SCART2 RGB inputs are R(59), G(57), B(58), FBLK/INSSW2 (54), except CTI/PIP option.
At PIP application ;
-
There are PIP_CVBS, SCART1, SACRT2, SCART3, FAV video inputs and RGB, FBLK inputs to PIP IC.
-
If there is no CTI application, PIP output is applied to SCART2 RGB input directly.
-
In case of PIP&CTI combined application, PIP output will be input to CTI IC as YUV. The YUV
output of CTI IC will be applied to R/Vin(59), G/Yin(57), B/Uin(58) as YUV.
