44 Kameleon HD Instruction Manual
Initial Configuration Process Overview
• Video Proc Amps – enable or disable all HD and SD video processing,
including color correction on the module with the Enable or Disable radio
button. Proc amp status will be reported on each of the Video Proc and
Color Correction web pages. Select the
Color Bars radio button to enable
the internal color bars test signal on the module output.
Note The internal Color Bars test signal is inserted at the output after the video pro-
cessing and is not adjustable with the video processor.
• J3 and J4 Output Selection – for modules with HD 59.94 or HD 50 input
type, output BNCs J3 and J4 may be either HD or SD video. Select the
HD or SD radio button to set the BNCs to the desired output. This choice
is also reflected in the graphics on the Functional View and I/O Config
web pages. Changing this parameter will cause re booting of the
module and the Wait web page (
Figure 28 on page 43 ) will appear until
initialization is complete.
• Standard Definition VBI/Data Lines – when the Advanced (VBI Config) radio
button is selected in the View Select, a control for defining data lines in
the SD and composite video VBI will be present. This control will only
appear when down converted SD or encoded composite video is
present.
Advanced VBI configuration allows you to extend VBI into the active
picture range for special data insertion requirements. Active video lines
that are used to carry data are referred to as Data Lines.
Select the 480i/59.94 or 576i/50 radio button to match the SD or composite
output rate. Select the last line (includes all previous active video lines)
that will be used for data. Selected active video lines will be shown in
the
Reserved for Data section of the web page as shown in the example for
lines 21/284, 22/285, and 23/286 in Figure 30 on page 46 .
Active video lines that can be made available for data insertion are:
• For 525, lines 21 – 24 in Field 1, lines 284 – 287 in Field 2
• For 625, lines 24 – 28 in Field 1, lines 337 – 341 in Field 2
• Output Timing – for all modules, an output timing source can be selected
from Frame Reference or Input . When Frame Reference is selected, modules
with frame sync capability (KAM-HD-FS and KAM-HDD-FS) can be
genlocked to the frame reference inserted into the 2000 frame. For these
modules, a Frame Sync web page provides horizontal and vertical
timing and freeze modes.
For modules without frame sync, when the Output Timing source is
selected as
Frame Reference , the start of any line of the output signal will
sync to the start of any horizontal line in the frame reference.
