NOTE: SMPTE RP 188 defines a standard for the transmission of time code and control
code in the ancillary data space of a digital television data stream. Time code
information is transmitted in the ancillary data space as defined in ANSI/SMPTE
291M. Multiple codes can be transmitted within a single digital video data stream.
Other time information, such as real time clock, DTTR tape timer information,
and other user-defined information, may also be carried in the ancillary time
code packet instead of time code. The actual information transmitted through
the interface is identified by the coding of a distributed binary bit. Equipment
manufacturers can use the meta data for different purposes.
User Bits
For monitoring a variable framerate (VFR) timecode (such as Varicam), you may
wish to check the User-bits box. If you set this checkbox, Io X3 will detect and
interpret the user-bits and display them next to the checkbox. You will see the
original framerate (30 fps in the figure below) followed by the adjusted frame
padding (two digits reporting discarded and retained frame padding).
NOTE: SMPTE 12M-2 is the updated name and specification for what was RP-188.
Presets Screen
After configuring the AJA Control Panel screens, you can then save all your
settings as a snapshot for later recall, called a preset. In this way, you can organize
presets for all your typical tasks, eliminating manual reconfiguration.
