BBG1040ACO-OM (V1.4)
Y/C Phase Alignment Processor
This function can correct upstream misalignment of Y and C phase (which is
typically introduced by upstream analog-to-digital converters, especially
where the Y and chroma paths may experience differing characteristics). The
function provides a phase offset of C phase from Y phase.
Color Corrector
Option
+COLOR
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. 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.
Character/Image Burn-in Functions
Text strings and timecode (as selected using the timecode function) can be
burned into the output video. Burn-in attributes such as size, position,
background, color, and opacity are user-configurable. Two discrete character
burn strings can be inserted on output video, with each string inserted as static
text and/or insert only upon LOS. A moving-box insertion can be enabled to
serve as a dynamic raster confidence check even in cases where the input
video image is static or lost.
Trouble Slate Insertion Function
Option
+T-SLATE
provides for graphic insertion onto the SDI processed
output raster. The function allows for uploading a .png image graphic file to
the card/device memory. (png files are converted to a special format using a
web tool before uploading to the host card/device; this is described in the
setup/operating instructions later in this supplement.)
When the image file(s) is uploaded to the device, its insertion can be enabled
via DashBoard Event Setup controls that enable the graphic insertion only
under certain conditions as desired. (For example, a trouble slate graphic can
be set to insert upon detected input Loss of Signal (LOS).
The trouble slate
function allows for positioning the image within the active
video using DashBoard controls. Refer to +LOGO / +T-SLATE Manual
Supplement OPT-SW-PHXLTS-MS for detailed information and installation/
setup instructions.
