Video Subsystem Description
Note: Descriptions below include some functions and features that are available
only as options.
(See Figure 1-4.) The 9985 features a frame sync that can select from either of
two card frame reference sources, input video, or free-run (internal clock)
video sync. In the event of input video loss of signal, the output can be set to
disable video, go to black, go to an internal test signal generator pattern, or
freeze to the last intact frame (last frame having valid SAV and EAV codes).
Video Processor
The 9985 provides full color processing control (luma gain and lift, chroma
saturation, and color phase) of the output video. The color correction option
(
+COLOR ) provides independent RGB channel controls for luma, black, and
gamma. The color correction function converts the YCbCr SDI input video to
the 4:4:4 RGB color space (where the color correction is applied), and then
back to YCbCr SDI on the output of the function. Controls are available to
adjust each RGB level independently for both white levels (gain) and black
levels (offset). Gamma can also be independently adjusted for each RGB
channels. Various controls can be ganged to provide adjustment for all three
color channels simultaneously. The color correction function can be
user-selected to be applied to input video or output video as shown in Figure
1-4.
