Datalist Color Coding
Different fi eld
s of the data stream are shown in different colors:
Green: Active video data.
Blue: Data in horizontal or vertical blanking intervals.
White: EAV and SAV packets; other reserved values such as the XYZ word.
Yellow: Data outside the nominal allowed values.
Red: Data with illegal values.
Quickly Finding SAV and
EAV in the Active Video
Stream
From anywh
ere in the video stream, pressing the CU RSOR button once will take
you immediately to the EAV of that line. Press it again to jump to the SAV of
the same line. This is also an easy way to move quickly to the beginning of the
ANC data, which is right after the EAV.
Datalist Display Pop-Up
Menu
Trace Type: Select from Video or Data. If you select Video, you can then
select to t urn on or off individual c omponents (traces) of the display. (Default
is Video.)
Video mode shows the data similar to the video Y PbPr display in
waveform mode, but without interpolation. The Y, Cb, and Cr traces are
offset vertically to separate them, but are aligned temporally.
Data mode using a SD signal shows the data in the same sequence as it
occurs in the serial domain. You see a sample of Y, then o f Cb, then of Y’
(Y prime), and then of Cr. Then the sequence repeats. The Y sample is the
co-
sited s ample and the Y’ sample is the isolated luma sample.
Data mode using an HD signal splits the serial input into a Y channel
an
d a multiplexed Cb/Cr channel. The intent is to show the data in the
same block structure as it occurs in the serial domain, even though it is
displayed as 8 or 10-bit values.
Format: Select from Hexadecimal, Decimal, or Binary. (Default is
Hexadecimal.)
Link Selection: Select from Link A, Link B, or Dual Link. This menu item is
onlyavailablewhenthetracetypeisData.
