SMPTE Interface
The SMPTE Interface is what gives the Binloop the ability to generate
and read SMPTE and EBU timecode. Whether it is generating or
reading, this interface provides the Control system with the current
SMPTE time. The most important purpose for this is to execute
precisely timed user-programmed commands, or triggers, to the
reproducer cards. In addition, it provides a SMPTE Frame Clock
which is used throughout the Binloop for synchronization purposes.
Configuration Options
The SMPTE Interface is a very powerful and flexible system and, as a
result, it has a variety of configurable settings. Here is a summary of
those settings:
Setting Description
SMPTE Mode
Determines whether the SMPTE Interface will
generate timecode, or read external timecode.
Framerate
The framerate in which SMPTE is generated.
Preroll Time
The initial time of SMPTE generator when it is
first enabled.
Start Time
The time that the SMPTE generator returns to
after it reaches the End Time (when looping)
End Time
The time when the SMPTE generator either
stops or loops back to the Start Time.
Loop Mode
Determines whether the SMPTE generator
loops continuously from Start to End Time.
Powerup Mode
Determines whether SMPTE is Enabled or
Disabled when the Binloop powers up.
Restart Mode
Determines how the SMPTE generator
responds when it is told to start again. It can
either restart or ignore the start command.
Idle Mode
Determines if the SMPTE Output is muted or
active when the SMPTE Interface is idle.
Self-Gen Mode
Determines how long the SMPTE reader will
free-wheel when external SMPTE is lost.
Output Level
Configures the voltage level (in dB) of the
SMPTE output.
These settings can all be configured using the Menu Wheel interface
on the front of the Binloop, or with through the Binloop Config
software. Please read on to learn more about these settings and how
they can be used to configure the SMPTE Interface to meet your
needs.
