The September 16 meeting on digital audio was hosted by Mark Parsons of Parsons Audio and the September 25 digital video meeting was hosted by Ross Kaufman of WCVB-TV. The two meetings were organized by Robin Shahid of Boston Post.
Ken Ainsworth of Tektronix gave an excellent presentation on SDI (serial digital issues) and testing as well as the importance of Signal Gamut. Key points of the meeting were:
Inherent SMPTE 259M weak points:
A reliable system must have at least 5 dB S/N margin for each link.
Signal Gamut (Gamut is the complete range of anything.)
Ken stressed the importance for monitoring all destination formats to maintain proper gamut and said that a comprehensive jitter specification for SDI will soon be available.
