Semi Standby
Initialize audio and video
processing IC's and functions
according needed use case.
Assert RGB video blanking
and audio mute
Wait until previous on-state is left more than 2
seconds ago. (to prevent LCD display problems)
The assumption here is that a fast toggle (<2s) can
only happen during ON->SEMI ->ON.
In
these states,
the AVC is still active and can provide the 2s delay. A
transition ON->SEMI->STB Y->SEMI->ON cannot be
made in less than 2s, because the standby state will
be maintained for at least 4s.
unblank the video
Wait until valid and stable audio and video, corresponding to the
requested output is delivered
AND
the backlight has been switched on for at least the time which is
indicated in the display file as preheat time
Release audio mute
