Before we go into too much detail, here are some basic definitions you should know (please
refer to the figure that follows for reference). After studying the basics, read “Who is
Controlling KONA?” later in this chapter for more advanced information on how applications
interact with the KONA LHe Plus board.
Control Panel Screens—the bottom area of the AJA Control Panel provides different
information categorized by topic. Clicking on one of the Screen links from the left
navigation column will result in an information screen corresponding to that screen’s
topic. Each of the Control Panel screens are described on the following pages.
Screens available are:
Control: configures the default output (test pattern, pass through, desktop, etc.) plus
setting genlock and output timing.
Format: select the framebuffer primary video format, any secondary.
formats, and parameters of conversion for input/output.
Input Select: view and edit input selections and how they are mapped.
SDI Output: assign outputs to either Primary or Secondary formats.
Analog Output: configure the component/composite +Y/C analog output.
Video Setup: configures Video options such as composite black level.
Audio Setup: configures analog audio monitor level and delay.
Conversion: used to select codec options such as whether paused video appears as a
full frame or a single field (jitter shown or not shown) and 24 to 30 fps padding
patterns.
DS Keyer: select downstream keyer mode, specify a graphic file or matte.
Timecode: m
onitor RP-188 timecode and configure timecode window burn output
(Note: SMPTE 12M-2 is the updated name and specification for what was RP-188)
Presets: add or delete saved preset configurations (handy for setting up the KONA LHe
for certain workflows and then saving it as a canned configuration for easy later recall)
Firmware: enables installation of AJA card firmware.
Info: displays status information about the KONA. This information is generally
intended for troubleshooting and support.
Block Diagram Screen—the top area of the AJA Control Panel shows a visual picture
representing the processing (if any) that's currently occurring, including inputs/
outputs, any down-conversion, reference source, and system status. Lines between
inputs, the framebuffer, and outputs, show a video path. Where there are no lines, it
shows there is no connection; this can be either because an input or output isn't
selected or because no video is present at the selected input.
Icon objects on the block diagram screen (input/output icons, frame buffer, etc.-also
called “widgets”-indicate their status by color (explained later) and when clicked will
bring up the proper Control Panel screen used to configure that item. For example,
clicking on an SDI output icon will cause the “SDI Output” screen to be displayed below
the block diagram. With the mouse on a block diagram element, you can also control
click to reveal contextual drop down m enus for certain functions.
Text Color—Colored text in the block diagram provides an indication of signal type and
what the KONA LHe Plus is doing. Text in blue shows the values automatically selected,
while text in black shows values that have been manually selected. Text in red shows
that the KONA is not detecting a signal or cannot negotiate with the attached device
(even if it can’t detect an output device, it still shows the signal it is outputting).
