In many experiments involving both data and video collection it may be desired to synchronize the collected analog/digital data with the recorded video. This paper demonstrates two LabVIEW Virtual Instruments (VI), which use a single A/D channel to collect and decode SMPTE (Society of Motion Picture Television Engineers) time codes. This paper will demonstrate the proper sample rate selection for bi-phase data collection, as well as the decoding of Binary Coded Decimal (BCD) data. The output of the VI will be frame number, hours, minutes, and seconds in ASCII format, which can be included with the collected analog data. These Virtual Instruments demonstrate a simple, efficient, cost effective method for synchronization of data and video.
