AJA Io HD Front Panel Indicators
The Io HD front panel provides a variety of visual indicators to tell you exactly
the state of the system and how video and audio are being handled. The topics on
the next few pages discuss these indicators:
•
Alphanumeric and Graphics display
•
Status and Power LEDs
•
Audio VU LEDs
Alphanumeric and
Graphics Display The alphanumeric and graphics display provides a view into the current Io HD
system status. When first powered up, the Io HD display shows an AJA logo,
followed by all the LED indicators lighting up (showing they’re functioning), and
then finally the current system status screen is displayed.
Information contained in the status screen shows:
•
Primary source selection and format (SD or HD format and framerate)
•
Secondary source selection and format (SD or HD format and framerate)
For example, if Io HD is currently set up to do a downconvert from 1080i 29.97
to 525i 29.97, the display would look similar to this:
The primary video is P1080i at 29.97 framerate and the video source is the SDI
input. The secondary source is 525i at 29.97. The audio source selected is from
the AES inputs.
Alphanumeric display
shows current state
of input and output
selection. It’s also used
for status messages when
appropriate.
The alphanumeric display has four screen fields
as shown here It can also display the Primary Video on top
and the current Timecode type and value at bottom
