be built with no SECAM chroma re-insertion filter
and no additionalcontrol switches.
The sum maybecancelled bysettingthe M8mode
bit. In this case, the VIDEO OUT2 pin is in high
impedancestateand the resistor network delivers
VIDEO OUT1 only.
When using the resistor network,please set M8 in
the following cases :
- in fullpage mode
- when OSD in not displayed
- to select opaque text. This allows the viewer to
selectby softwarethe preferreddisplay mode.
The DC levels of theVIDEO OUT1, VIDEO OUT2
and the sum signals are high enough to directly
drivea NPN emitterfollower driver (see Table 1).
9 - VIDEO FULL PAGE MODE
In additionto thenormal fullpage mode in whicha
uniformely colored screen background is gener-
ated, the STV5730 is able to support a ”video full
page mode”.
Normal and video full page mode are selected by
the controlbit C11 (respectively set high andlow).
By using the video full page mode the channel
capture operation can be easily monitored on the
screen since the signal at the VIDEO IN input is
displayed, unlocked, in the screen background
area ; the text being stable and colored, with or
Table 1
without colored background.
Presence detectionis permanently active to keep
the microcontroller informed of the input signal
quality. The information is delivered by the MUTE
pin.
Thisinformationcanbeusedbythemicrocontroller
to forcetheSTV5730 into the mixed mode (set C0
low) when the input signal becomes good enough.
In thevideo full page mode, it can be usefull to set
the M11(mode register)bit high, so that the mute
signalis notsynchronizedontheverticalsync,thus
acceleratingthe VIDEO IN presence detection.
10 - S-VHS APPLICATION
(seeFigure 5)
The STV5730can be used in S-VHS applications
easily.
The Y signal must be delivered to the VIDEO IN
input. The VIDEO OUT1 output then delivers a
Y +text signal,whilst theVIDEOOUT2 deliversthe
Y input signal, provided that the CIN input is con-
nected to abias DC level.
An external switch must be used to select the C
signal in mixedmode or the COUT outputsignal in
full page mode.
In mixed modethe chromasignal (C) can be exter-
nally attenuated(multistandard translucent opera-
tion) or killed (PAL/NTSC opaque operation only)
during the character gate controlled by the fast
blankingsignal.
