Extended View
OmniTek XR offers an alternative ‘Extended View’ of the Data View window. When
Extended View is selected within the Options menu, the standard pixel value display is
enhanced through the addition of pixel colour data and descriptions of identifiable
structures such as VANC packets in the video signal.
The range of information that can be displayed depends on whether the video signal that
is being analysed is SD or HD or dual-link. For instance, combined Y/C information is
displayed for SD signals, but separate Y-type and C-type information is displayed for HD
signals. The range of additional information to display is selected through the submenu
associated with the Extended View menu option.
Within the active video, both a value and a set of pixel data are shown for each pixel. In
dual-link input formats, the RGB and XYZ colour space data is assembled into full pixel
values.
Within the blanking area, VANC packets are identified and interpreted by comparing the
signal received against information supplied alongside OmniTek XR as XML files. These
files enable the identification of a range of AES controls, SMPTE time codes and RP188
control codes. Users may also add their own packet definitions to install XML-format
descriptor files, for decoding custom VANC packets. If the VANC packet is not one of the
standard types ‘understood’ by OmniTek XR, the heading “Unknown VANC packet” will
be displayed together with the embedded ID to allow separate identification.
Options menu
The Options menu for the Data View window includes the following choices:
Save # samples
Sets the number of pixel pairs displayed in the Data View window (and saved when
a snapshot of the Data View is taken).
Base
Offers the choice of displaying the data as decimal, hexadecimal or binary values.
Viewing Format
Offers alternative ways of formatting the data that is displayed. Dual-link video signals
can be interpreted either as 10bit or as 12bit. 8:2 interprets 10bit data as 8 bits + 2 bits.
This has the advantage of making standard groupings such as those associated with
SAV and EAV easier to pick out.
