Nielsen's New Encoder and Monitor


Guest Speaker: John Stavropoulos

IMPORTANT NOTE:  Due to a scheduling problem, it was necessary to RESCHEDULE this meeting for Wednesday, March 25th, at 6:30 PM.

This is a joint meeting of the Baltimore and Washington SBE Chapters.  To accommodate those who will be traveling greater than normal distances, please note that this is an evening meeting.   

Our guest speaker will be John Stavropoulos, Vice President Engineering & Supply Chain Management, Nielsen.  John will be introduced by Ellen Promisloff, Nielsen's Account Director, Client Service.  Nielsen will present their new 1212 Analog-Digital Encoder and the soon-to-be released 1220 Multi-channel Monitor. John's presentation will focus on the technology utilized within these new products. 

As explained below, Nielsen Encoders and Monitors have quickly become a vital element in the station signal chain.  Therefore, this meeting is sure to be interesting to local and network television, radio and cable-TV engineers.

When learning the fundamentals of commercial broadcast engineering, many of us were taught the undeniable relationship between The Three R's:  Reliability, Ratings, and Revenue.  Although Ratings and Revenue are largely envisioned as responsibilities of the Programming and Sales departments, both are dependent on the abilities of the Engineering department to Reliably deliver high-quality audio and/or video.  Without that, Ratings and Revenue will surely suffer.

At one time, the station transmitter was thought to be the primary limiting factor for station Reliability.  However, with the advent of the Portable People Meter (PPM), which detects inaudible digital watermark signals encoded within a station's audio stream for ratings research, proper operation of the Nielsen Encoder is arguably as important as the transmitter.  After all, if the station is on-the-air but not getting ratings credit, how much does it matter?  By extension, confidence monitoring of the broadcast PPM watermark signal is important for determining that the Encoder, broadcast signal chain, and transmitter equipment is functioning properly. 

We're sure you'll be interested in the discussion about PPM encoding, the 1212 Analog-Digital Encoder, and the soon-to-be released 1220 Multi-channel Monitor.  Please mark your calendar for the Wednesday, March 25th 6:30 pm meeting and RSVP (see below) if you think you'll be joining us. 

Sandwiches, kindly provided by Cavell, Mertz & Associates, Inc. and soft drinks kindly provided by Nielsen, will be served at 6:30 PM.  We'll discuss a tiny bit of Chapter 37/46 business about 6:45 and begin our presentation about 7:00 PM.  Please RSVP by Noon on March 23rd by dropping an e-mail to and let us know if we should expect you for dinner!

Thanks to our friends at SBE Chapter 46, Baltimore for their efforts planning this meeting.
