Summary0000567: HDMI Output during the Active Standby
DescriptionHi Mr. Jacky Chiang,

When we turn off our STB with "Btv 전원" button of RCU, then STB looks turn off and display black screen on TV.
But after that TV shows the still picture on the screen.
We are not know who is in charge of this part. But please check it and inform your review .
Our expectation is
     1. STB should HDMI off. So TV display "No Signal" message,
         STB should not show Black screen via HDMI.
     2. Keep HDMI off until user turn on the STB.

After check the logcat,
TVS called setHDCP(0),
In this function,
It will write -1 to /sys/devices/virtual/amhdmitx/amhdmitx0/avmute,
and HDMI will turn on.

I've gave the information to JingYu, Amlogic will check with TVS

It is a feedback from TV Storm.

They already remove setHDCP(0) after HDMI output mute when Active Standby mode.(3/21)
They want to implement HDMI Output Mute function as follows :
          If user set HDMI output Mute, then HDMI donot send any signal to TV.
          It is not black color output to screen.

They think Amlogic fix it. Amlogic said that it work as TVS expected in their reference board.
So Amlogic look into it.

Hi jim

We checked internal.
Following commands are way to make sure disconnect hdmi with TV.

=================================================
echo 1 > /sys/class/amhdmitx/amhdmitx0/avmute
sleep 0.05
KILL hdcp_tx22 PID
echo stop14 > /sys/class/amhdmitx/amhdmitx0/hdcp_ctrl
echo stop22 > /sys/class/amhdmitx/amhdmitx0/hdcp_ctrl
echo 0 > /sys/class/amhdmitx/amhdmitx0/phy

we are checking with internal and we will modify removeOutput api in SystemControlManager.java.
SKB's active standby mode means only hdmi off, so foxconn dont need to do anything on this.
