<INFO> block
The signal info block contains general information about the signal. The first character of this block is S.
Format: S<a><b><c><d>
Identifier Parameter Description
<a> 5V power presence
<b> Signal detection
<c> DV/HDMI mode indicator
<d> HDCP state
Example: S1131
5V and active video signal is present in HDMI deep color mode (36 bpp), HDCP is active.
<video> block

INFO: This block is present only if valid video signal is present on the selected port.
The resolution, refresh rate, scan mode, and color space information are described in this block. The first
character of this block is V.
Format: V<Resolution>,<Hsync>,<Color_space><3D_format>
Identifier Parameter Description
<Resolution> <Width>x<Height><Scan><Vsync>
<Hsync> Horizontal sync
<Color_space> Color space information
<3D_format> 3D format descriptor
Example: V720x576p50,313,00
720x576 signal resolution is detected with progressive scan at 50 Hz refresh rate; vertical sync value is 313
kHz and the signal is in 2D format wat RGB 4:4:4 color space.

<audio> block

INFO: This block is present only if a valid video signal is present on the selected port.
The audio info block determines the type of the audio, the decoded sampling frequency and some further
information extracted from Audio InfoFrames. The first character of this block is A.

<d> Audio channel number
1..7 = channel number is equal to (<d>+1)
7-5 bits:
reserved and shall
be 0 (zero)
Sampling frequency and
sample size (encoded
<ee> in HDX format and
represented by binary
format)
example:
0F = 000 011 11
48 kHz sampling frequency and 24 bit sample length
This byte describes how various speaker locations are
allocated to the audio channels:
Speaker locations FR/FL = Front Right / Front Left
LFE = Low-frequency effect
<ff>
(See the following table FC/RC = Front Center / Rear Center
for the possible values) RR/RL = Rear Right / Rear Left
FRC/FLC = Front Right Center / Front Left Center
RRC/RLC = Rear Right Center / Rear Left Center
