View Full Version : Delsys myomonitor & Video synchronisation

03-07-2007, 02:00 AM
Dear all

I have been trying out synchronised video capture with our Myomonitor III
system via EMGWorks. I have used both JVC DV and basler firewire systems and
have seen that for 15s EMG data I get between 15.9s & 16.03s worth of data.
When analysing the files the emg and video data do not appear synchronised but
are about 1s out.

Delsys replied " ... you must manage the inherent delays of the
wireless communication. The problem is exasperated by Windows, since
the camera is actually operated by Windows, not EMGworks, so we have
little control over the true timing. Our future version of EMGworks will
address camera synchronization much more rigorously, so we hope to
resolve this problem downstream. This will not be available for another
year or so."

Has anyone managed for find a way of getting over such a problem?
