Muting signal is for component video(YUV) output. igh is
i- (0V) for component video output is enabled. And low disable the
component video output.

Control signal for Power On LED indication with reen color.
For the blink condition:
1.) reen Led blink at 1sec intervals between power-on and
Low(0V) boot. The LED keep the light after the boot finishing.
2.) reen Led blink at 1sec intervals before the system becomes
Standby compeletely when the power key is pressed in
power on mode.
Control signal for the Standby LED indication with red color. The
igh(3.3V) LED is light in standby mode. And turn off the LED in power on
mode.
This control signal is to set the low pass filter bandwidth for
i- (0V) Component output. igh is in 720P, 1080i output mode. And low
is in 480i 76i, 480P 76P output mode.
