Legend: <INPUT_D> may contain 9, 17, 33 or 80 hexadecimal numbers. Each number
represents the state for the corresponding input port. The meaning of the responded
number depends on the actual board (port) type. The binary representation of the responded
hexadecimal numbers is shown below.

7.6.3. Get information about input port
Description: You can get more detailed information about an input HDMI port with this
command. The response will contain information about the general signal parameters, the
video resolution and mode, the audio format, other advanced parameters and the actual
settings on this port.
The response repeats the number of the input port after the STI string. There are different
blocks present after the equal sign, which are separated by semicolons. Every block
contains different type of information and can be recognized about the first character. For
example, a block started with 'V' is about the video resolution and format. Some of the
blocks might be missing depending on the actual signal – e.g. if the port operates in DVI
mode then no audio information will be sent.
Command {:HDMIIGET<in>}
Response (STI#<in>=<INFO>;<VIDEO>;
The exact meanings of different blocks are explained in the following sections.
Legend of <INFO>
The signal info block contains some general information about the signal. The first character
of this block must be S.
