Closed Captioning Processor
Note: The closed captioning function is tied to and considers CC sources only
received on SDI IN A.
This function provides support for closed captioning setup. The function
allows the selection of the ancillary data line number where the ancillary
closed caption data is outputted when the output is HD. The function allows
closed captioning packet removal. Regenerate Closed Captioning function
can be used to move the packets to a different VBI output line, if desired.
Character Burn-in Functions
User text 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.
Audio Select/Embed
The audio processor operates as an internal audio router for selecting
quadrant-input embedded channels 1-16 as channels (as a four-group
package) to be embedded into the combined SDI and HDMI video outputs.
The audio processor function operates with the timing alignment function to
align audio with the selected reference.
Note: • Output audio always corresponds to a single particular selectable quadrant
input. Various output embedded channels cannot be sourced from a mix of
various quadrant input embedded channels.
• To maintain conformance with CEA-861D HDMI audio channel line-up
specifications and industry standard SDI convention, the HDMI output
swaps between the C and LFE channels for the HDMI output.
Figure 1-3 shows the user control interface for the 9902-DC-4K. Using
DashBoard™, the 9902-DC-4K and other cards installed in openGear®
frames can be controlled from a computer and monitor.
DashBoard™ allows users to view all frames on a network with control and
monitoring for all populated slots inside a frame. This simplifies the setup and
use of numerous modules in a large installation and offers the ability to
centralize monitoring. Cards define their controllable parameters to
DashBoard™, so the control interface is always up to date.
