TG8000 Multiformat Test Signal Generator User Manual
SDI7 Dual Channel SD/HD/3G SDI Video Generator module
All of the signal sets that are available in the module are already assigned to the
corresponding test signal buttons. (See Table 3-59.) When the SDI7 module is
selected and you press any of the front-panel test signal buttons, the selected
signal in the signal set is output. (See Figure 3-115.)
For example, when you press the COLOR BAR test signal button, a signal in
the Color Bars signal set is output. Use the left (◄) or right (►) arrow button, or
press the COLOR BAR test signal button repeatedly to select a different signal
from the Color Bars signal set.
Figure 3-115: Front-panel test signal buttons
The following table lists the signal set assigned to each test signal button and the
signals that can be selected in the signal set when the module is in generator mode.
Description
Eight full-height bars of white, yellow, cyan, green, magenta, red,
blue, and black. This pattern is available with three variations, at
100% value for all bars, at 75% value for colors and 100% for
white, and at 75% value for all bars.
These variations on color bars are available only in the 625 50i
format of the SD output mode. They consist of the 75% or 100%
color bars signal on the top half of the raster, and a matching 75%
or 100% red field on the lower half.
Color bars per SMPTE EG 1-1990. This pattern includes 75%
color bars, reverse blue bars, −I and +Q sections, black, white,
and pluge sections. Note that this pattern is only available for
YCbCr formats, since the −I and +Q sections contain color
components outside of the legal RGB gamut. For the SD output
mode, this pattern is available only for the 525-line 59.94i format.
Color bars per SMPTE RP 219-2002. This pattern is intended for
16×9 aspect ratio displays, with additional elements as compared
to EG1 bars. The SDI7 implementation includes −I and +Q
sections, but unlike the similar sections in EG1 bars, they have
additional luminance to stay within RGB gamut. The −2% patch
of the pluge section is clipped to 0% black for XYZ formats. For
SD, the color bars are the 4:3 aspect ratio version, as if converted
from the 16:9 image with a center cut.
