Timecode Control
In this method of control, the commands are pre-programmed ahead of
time using the Binloop software, and then downloaded and stored in the
Binloop.
The concept is pretty simple. When you program the commands, you
must specify a SMPTE timecode value for that command. If the SMPTE
clock ever equals that timecode value, the command (or trigger) is
executed. This concept applies whether the SMPTE is being read from
an external source, or generated internally by the Binloop.
There are several benefits to using this control interface. First, this
interface allows the Binloop to operate completely on its own. For
example, you could program the Binloop to automatically generate
SMPTE timecode when it powers-up. You could then create a ‘Play’
command that gets triggered by the timecode shortly after it starts
running. The result is that the Binloop automatically starts playing after
power-up with no external control required!
The other benefit to this interface is precision. Each command’s SMPTE
execution time is accurate down to the frame. For example, you could
make a video start playing at exactly 01:02:05.21. Again, it doesn’t
matter if that timecode is being read from an external source or
generated internally. This precision also helps with tweaking the
playback timing. Is the video starting a little too soon? Just add 1 or 2
frames to the SMPTE execution time to make it start a little later.
For more information about using this method of control, please refer to
the
Binloop Configuration Software section of this manual. If you
would like to configure the Binloop to automatically play upon power up,
please see the
Application Notes section of this manual.
