Has anyone decoded SMPTE timecode in Labview?

[lancetboy76]

Hi,

I need to synchronize analog voltage acquisition with video data. A SMPTE timecode is created by a generator and is recorded along with the voltage data. I would like to know if anyone has figured out how to decode this SMPTE data in Labview. Does IMAQ include any SMPTE functions? Does NI sell any hardware that decodes SMPTE?

Hello,

I'm not familiar with the SMPTE time code but you can certainly synchronize your image acquisition with voltage acquisition. The following link is to an example that does synchronized acquisition from a frame grabber and a DAQ card and overlay the voltage measurements on the video data: http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3EA7B56A4E034080020E74861&p_node=DZ52489&p_source=external
I hope this helps!

Thanks Yusuf,

Even though I have a lot of experience with Labview, I would need help in developing such a system. I am not sure what frame grabber would be appropriate. I need to synchronize video capture and analog DAQ. This acquisition also needs to be done continuously for up to 60 seconds. I need to collect 12 channels of analog data at 10KHz. What I have been using before is a Pentium 3 laptop for the analog DAQ (with a PCMCIA DAQ card), but that has never run smoothly. Perhaps I need to move up to a desktop with faster disk I/O.
