Input Signal Automatic Detection

The MSD continuously monitors input signals. If input signals that have been input before, they are output
with the same size and quality of view used previously. If input signals are not matched with any signal
settings that have been input before, only settings of input timing is initialized and other settings are not
changed. Adjust the size and quality of view as necessary.
The MSD saves data of 50 input devices for each channel, and the data is used to check whether the input
signals have been input before or not. To save the data of the 51st device, the oldest data that have not been
input recently will be deleted, instead.

When new signals are input, the oldest data will be overwritten.
The data of the following settings are stored for each input signal.
