During the broadcast, there is often a need for an on-line switch-off of the stream.
The program is not always convenient. This task is successfully solved by the popular device after my modification.
If any of the HDMI inputs (1,2 or 3) is connected, the signal from the 1st input is transmitted to the output. The absence of a signal when connecting 1 HDMI input causes a pause in the broadcast.
When the button is pressed, the output switches to the next connected input and again to the 1st input.
In this way, you can specify (or switch) the HDMI signal on the encoder input.
Perhaps soon the encoder will be optionally equipped with such a set .
