Video Input
The 5 mini viewers at the top of the video input panel show the previous 6 seconds of your live
stream, each mini viewer represents 1.2 seconds of streaming time.
Below the mini viewers you can view detailed technical information about the video input
source connected to your Web Presenter's SDI input.
Input Standard
Displays the resolution and frame rate of the SDI video input. Web Presenter
supports up to 2160p60.
Colorimetry
Shows the color space of the SDI video input. Web Presenter supports
Rec.601, Rec.709 and Rec.2020 color spaces.
SDI Ancillary Data
Ancillary data is data carried in the SDI video input that is in addition to
video. This includes embedded audio, timecode and closed captions.
If your SDI input includes ancillary data then 'Present' will be displayed.
Timecode
Displays the timecode from the SDI video input source.
Closed Captions
If your SDI video input includes Closed Captions the format will be displayed
here. CEA-608 and CEA-708 formats are supported.
SMPTE 292 CRC
This is an error checking function for SDI video. If your Web Presenter
detects a problem in the SDI video input it will display an error.
CRC errors are usually caused by a faulty SDI cable or a cable that is
too long.
Luminance Y Bits
The indicators for 'luminance y bits' and 'chroma bits' show you the activity
and Chroma Bits
of the SDI video input signal. Each letter represents the state of one bit of
the video signal.
X - An 'X' indicates a constantly changing bit.
L - A low bit.
H - A high bit.
SDI offsets are subtracted to make it easy to understand. For example,
all bits are low when video is black.
Generally, all 10 bits for your SDI video input will show 'X' to mean all the bits
on your video stream are changing constantly. If your SDI input is 8 bit video,
the two rightmost bits will always be 'L' as they don't have any data. If a bit
stays 'L' or 'H' when you expect it to be 'X', this indicates a 'stuck bit' and
could be the result of a fault in the upstream video.
