<video> block
INFO: This block is present only if valid video signal is present on the selected port.
character of this block is V.
Format: V<Resolution>,<Hsync>,<Color_space><3D_format>
Parameter Description Parameter Values
<Resolution> <>x<Height><Scan><Vsync>
<> = active video width (pixels)
<Height> = active video height (pixels)
<Scan> = p: progressive, i: interlaced scan mode
<Vsync> value (Hz)
<Hsync> Horizontal sync <Hsync> value (kHz)
<Color_space> Color space information
0 = RGB444
1
2
<3D_format> 3D format descriptor
0 = 2D signal
1 = frame packing
2 = top-bottom
3 = side-by-side (half)
4 = Field alternative
5 = Line alternative
6 = Side by side (full)
7 = L+depth
8 = L + depth + graphics
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.
