MX-FR Series Modular Matrix Frames – User's Manual
132
Applied CPU2 firmware: v3.5.7b8 | LDC software: v2.5.17b2
Example:
A1C010000
PCM audio is present at 48 kHz. The codec is not specified, two audio channels are defined.
INFO:
Please note that the values of
<c>
,
<d>
,
<ee>
and
<ff>
parameters are based on the audio info frame
sent by the source device, while values of
<
a
>
and
<
b
>
are based on measurements. Audio info frames are
forwarded in unchanged format to the HDMI sink devices (e.g. AV receivers) so that they would be able to
interpret the InfoFrames correctly.

block
INFO:
This block is present only if a valid video signal is present on the selected port.
For advanced users this block provides information that could be useful during debugging process. The first
character of this block is I.

VSYNC polarity
0
= VSYNC polarity is negative (leading edge falls)
1
= VSYNC polarity is positive (leading edge rises)
<

HSYNC polarity
0
= HSYNC polarity is negative (leading edge falls)
1
= HSYNC polarity is positive (leading edge rises)
<

TMDS clock line signal
presence
0
= There is no change on the TMDS clock line
1
= Signal is present on the TMDS clock line
<
d
>
TMDS clock line stability
0
= The clock signal is unstable on the TMDS clock line
1
= The clock signal is stable on the TMDS clock line
<
e
>
Active Format Aspect
Ratio based on AVI
InfoFrame
0
= Field is not present (e.g. DVI signal)
2
= 16:9 (top)
3
= 14:9 (top)
4
= greater than 16:9 (center)
5
= Same as picture aspect ratio
9
= 4:3 (center)
A
= 16:9 (center)
B
= 14:9 (center)
D
= 4:3 (with shoot and protect 14:9 center)
E
= 16:9 (with shoot and protect 14:9 center)
F
= 16:9 (with shoot and protect 4:3 center)
<
f
>
Pixel repetition factor
based on AVI InfoFrame
0
= No repetition (i.e. pixel sent once)
1
= Pixel sent 2 times (i.e. repeated once)
3
= Pixel sent 4 times
Example:
I1111A0.
Positive HSYNC and VSYNC, stable pixel clock, 19:9 aspect ratio and no pixel repetition.
